Bilbao... Basque Country....Spain. Probably has existed from 1300s. Home of the Guggenheim museum designed by Frank Gehry, one of his best works of architecture. Also, a pillar in Spain's gastronomy. One of Spain's major ports, etc, etc
Bilbao is in Spain. I have been there. They even have a Guggenheim museum there. On my travels in the past i remember getting the best food in Bilbao spain.
3:37 I love home grown tomatoes! They actually taste like tomatoes. 😃 What a concept. And thanks for the preamp and line out info too. Believe it or not, I just realized that I can probably connect my modern AV receiver to my antique Carver C-4000t stereo system through the line out RCA's. iTunes and computer audio out through a real stereo with real speakers! It's only taken 13 years for the light bulb to go off. (Some of us are a little slower than others.)
My wife and I went on a trip to spain. Four days in Madrid and four days in Bilbao. Both are beautiful cities (objectively, Madrid is more impresive), but after several days of the cacophonic inferno of Madrid, Bilbao was absolutely wonderful - tranquil, clean, and relaxing. And the Guggenheim,, out of this world - I could have spent a week gazing at that building from all angles, inside and outside.
It's true that many high-level sources such as CD players will put out plenty of voltage to drive a power amp to full output, or into clipping. Hopefully most owners realize that sources lacking volume controls should only be connected directly to a power amp, if the amp has its own level control(s).
I was connecting-up a friend's stereo. His teen sister was handing me labeled wires and one set was from a simple reel-to-reel which didn't have a preamp stage. The receiver was a Sansui 500 from the early 1960's and it had a tape head input and output. When it was time to hook up those, I asked her to give me "head". I haven't spoken with my friend for 40 years, but his sister still likes me.
I finally had this explained to me. After researching this a bit I gave up and learned by trial and error. And yes it was very loud. Luckily my powered speakers had volume control in front.
@@TorToroPorco i mean the poison of what they give you on the market, and i recommend garden, and dont believe that tomato is bad, if you consume it right, i believe God created it right, and it is good for health, after you thank God, ...atheists should still wait for the tomato to fully evolve at its best, 😂😂😂. this what you say is like saying that God did it wrong. Oh really? Of course this is how people think, some foods are toxic, because they are so powerfull and healthy, but they dont have pure mountain water to flush out those bad things, because they are feed of sterilized water, and this means that it is not Gods fault, that He made wonderfull things.

You audio tweaker want to get more in depth with sound. Let's go way out to extreme tweaking! Let's break down the different sound waves entering the ear of different physical attributes of everyone's born shape and position of their ear. Yep, everyone hears differently. At least on the level of really tweaking sound level, travel, and how much wax each person's ear has or doesn't have. LOL!
i'm trying to use line out from a pioneer sx-10ae to provide an fm signal to a fosi V1.08 external amp to power some elac 6.2 speakers along with 2 sets of speakers powered by this receiver. the fosi has volume control and rca inputs. anyone forsee any problems?
I have an integrated amp with volume controll. It has a tape out connection. Can I connect to this tape out an independent preamplifier which has volume controll too ?
The simplicity of wisdom! It's awesome to listen Paul's explanations! So, the max volume of a pre amp out would be the pure signal of it's input, most of the time +4dBu, is that right?
So, question for Chris - he’s really smart, by the way - can you explain how back loaded horns and transmission lines work, and are there any rules of thumb to make them work? (This question comes from Jens, pronounced Yens, in Elmbridge, England)... Love your work. Since lockdown it’s become a daily ritual to watch and learn.
Great video? Do you have a suggestion for an off the shelf external buffer that one could utilize if they have an older tube amp with the tape out and no internal buffer?
Paul, get your wife to add more organic matter such as compost and mulch to her vege patch and see it suddenly grow faster and healthier. Seaweed juice and worm castings does wonders as a plant tonic too!
Paul. Is it correct to say that "line out" is from mixer or pre-amp is fixed at -10dBV for consumer and +4 dBu for pro audio? And "preamp-out" is modified line-out?
No, line out levels will depend on the selected source. It can be much higher if a source like a CD player or DAC is selected, and will likely be lower with sources like portable players. Output from a pro audio mixer can be much higher than +4dBu; most are capable of +20dBu.
@@hightttech Line out (or record out) is fixed level, in that it isn't affected by volume, balance, or tone controls. Signal levels for consumer equipment are all over the map. The lowest you are likely to encounter is 300mV (-10dBV), but some consumer sources will put out 2V or more. In pro audio, signal levels between components are typically around 1-2V, but can go much higher since mixers are usually capable of 8-10V.
@@marianneoelund2940 : I thought LINE LEVEL output standardized so input level at power amp unchanged when you change your source... e.g. wouldn't LINE OUT from DVD player and DirecTV box both be fixed at -10dBV (consumer) so that switching between those two sources does NOT require adjustment of power amp to maintain same listening level in the room? Thanks for your thoughts.
@@hightttech My experience suggests that if there is a standard, many devices do not follow it. My TV, CD players, DVD players, PC have rarely been the same level and so need gain adjustment when switching between them. My new Rotel preamp allows me to set default gain level on individual inputs which is kinda handy.
Bilbao is a city in Spain (I suppose you know what the heck is Spain). It is also funny that the guy from Bilbao has not written the country name he is writting from... I would have paid for him writing Euskadi to see Paul's reaction to that! 😂
It's amazing how many autonomous communities and regions exist around Europe and in other countries around the world. Many of them only came into official existence in the last 40 years or so.
In a signal path of a PC/Mac/phone --> DAC --> power amp, you are connecting a "line out" to a power amp and rely on the volume control of your digital source. It sort of works, but beware that digital volume control is potentially reducing the bit resolution e.g. a 24 bit audio file attenuated to less than max volume in your PC will in some cases lose resolution with 1 bit per -6dB thus -48dB volume will yield effectively 16 bit CD resolution of your 24 bit FLAC file. But -48dB volume is likely so low volume that you can't hear you just lost your high-res performance.
Yes. A full volume (100%) on the iphone/iPad is to be kept if you want the full resolution. At that point, the device does not manipulate the digital output. Control the actual analog volume on the amplifier that is feeding your loudspeakers
Unless you have a preamp or receiver with individual input level adjustments, it's important to understand that line out level will depend on the selected source. The range between low-level and high-level sources can be 15dB or more. There can also be a significant difference in the output impedance. For example, my old Pioneer receiver has over 2K ohms output impedance at its line (record) outputs, but the preamp out is less than 300 ohms. The lower output impedance reduces noise susceptibility, and avoids high-frequency rolloff if you use very long cables. The higher output impedance is only intended to drive relatively short interconnects, typically 2m (6').
@behexen250 Recognize this? Vn = SQRT(4 * k * T * B * R) Now tell me again, that impedance has nothing to do with noise. Recognize this? Vn = Z * In, where Vn is noise voltage and In is induced noise current. Now tell me again, that impedance has nothing to do with noise. What does the "VLZ" stand for in the Mackie mixer name 802VLZ, and why does it have that? I've designed low-noise preamplifiers that achieve 0.5dB noise figure or better. Do you even understand what that means? "Lower the gain, and you lower the noise." Oh my, what a profound insight! Until you mentioned it, I'm sure no one else in the world had ever thought of that. Hey, here's an even better idea: Turn the power off, and the noise goes away completely! Magic!
@behexen250 I'll take that as an admission that you have no idea what the noise equations mean. Since it apparently hasn't occurred to you yet, you can see my employer and job title by searching campaign donor public records - but note that I recently retired. That means I accumulated near 4 decades of design experience as a fully qualified, degreed EE with an aerospace company, designing and developing analog and digital circuitry for flight control electronics, mostly used on Boeing commercial airplanes. First program, back in the 1980's, was the full flight regime autothrottle computer for the 747-200, also used on a few 747-300's, including Air Force 1. It's an analog computer which also employs MSI CMOS logic for mode control and BIT. My design responsibility was updates for control law and interface changes, including a full re-design of the BIT subsystem. Many other programs over the years used my analog and digital circuit designs in actuator control electronics, active stick interface electronics, primary flight computer for the Boeing 777, plus a number of prototype and test equipment designs. I'm certainly not going to attempt listing every design task here. With regard to what you call "McDonalds level equipment," the Mackie mic preamps come very close to the theoretical noise limit for operation at room temperature. This is achieved by using low-impedance design methods, the importance of which is clearly lost on you. Fundamentally, optimal low-noise designs must be tailored to a specific source impedance; preamp design is quite different for high-Z sources, than it is for low-Z sources. The mic preamp I designed and built, achieves 0.5dB or better NF with the high-Z microphones it was designed for, but it would not perform as well with low-Z mics. Your concept of "gain related noise" is strictly user-level, not a term used by analog design engineers. We work with source and component voltage noise and current noise specs, to build representative models and achieve target equivalent input noise (ein) levels and SNR performance. We also employ a variety of methods to protect sensitive inputs from induced noise; I have experience in design for EM hardening in flight controls, as well as commercial audio installations where I have solved a number of noise issues.
@Lloyd Stout 1. It isn't "my" formula. 2. As I didn't provide any examples of applying it, how can you conclude whether or not I understand it? 3. I still have hardware that I designed and built many years ago, and the measured performance agrees with the expected performance that I calculated using that formula. 4. I had to apply that formula for a design project during my analog design class at the UW EE dept., which was checked by my professor. He didn't find any problems with my calculations. 5. That same professor surprised me with an unexpected and stern challenge when I went to pick up my graded final exam at the end of the course: "How did you get a perfect score on the final? No other student of mine has ever achieved that."
@behexen250 The only "issue" I have, is with incessant needlers who keep demanding examples, immediately after I had already provided them. I will not entertain continued discussion when it has become circular and is unable to progress due to the other party's abject refusal to accept valid evidence. It has happened only one time that I deleted posts under those conditions - and not because of any errors on my part as you attempt to suggest - yet you pose it as though it were a regular occurrence. And which one of us is making derogatory personal remarks about the other's behavior, motivations and emotions? How does that add any value to technical discussions?
@behexen250 "I take it all back. Stick with preamps, not airplanes. I'm sure your designs are excellent." You just blew up my sarcasm detector's input stage. Thanks a lot. I'm sending you the repair bill . . .
This is not a problem. Just set the volume of the unit in which you are using line in to the maximum (if it has volumen control, although you can set the second volume control to match its sensitivity to the pre amp output level if it needed) so you can control the signal level from the pre amplifier. I supose that this is your intention. Best regards.
If the sending receiver has a pre-amp out with a return amp in circuit use a y cable from the pre amp out to split the signal ,one will go in the amp return on the sending receiver and the other send will go to the other receiver on which you could use an aux or tape input
There's a MAGNIFICENT Guggenheim museum/art space in Bilbao. And the BBVA bank, one of the richest in the world, is in fact from Bilbao. Great city in northern Spain. You should visit it. 😉 About the question, great q, I had exactly the same q.
Hello! I have a Yamaha R-N420D (very basic) receiver which has only 1 'line out' (full powered for i.e. recording). I use this receiver to receive an ethernetcable so I can play flac files from my computer through the LAN network. Next to that I have a Cambridge Audio - Azur 840A V2 which is a way better quality amplifier, but doesn't have an ethernet receiving port. I would like to receive music through the yamaha receiver (ethernet) and send it to the cambridge audio amp which drives my speakers (2x KEF LS50 and 2x Monitor Audio GS20. Is it possible to use the simple 'full powered - line out' of the yamaha receiver to connect the Cambridge amp and will it sound any good? Any insights are greatly appreciated!!! Thanks!
Bilbao is a town in Spain, Bascony and the place that was demolished by bombarding of German bombers before WWII and Pablo Picasso made famous Guernica painting based upon that catastrophic event.
Sir your videos are very useful.. could you plss tell me is it possible to connect 4 channel amplifier with 4 speakers and one subwoofer ..my car stereo have 4 preout..
Hi Mr Paul, I have a isd 1820 module. It is a simple record module. The output is a speaker output. How can i make this signal less hot and put a 1/4 jack as a line out. Thanks in advance!
I learned from book by an American that Basque fishermen went to New Foundland even before Columbus mistook America for India. But they kept it secret because the fishing was so good, back then. Where the heck is Boulder?😀
My question is: Can i connect a pair of subwoofers to preout connectors? Won't burn the imput circuits of the subs? My preamp doesn't have a stereo sub out.
Bilbao is in Spain. It is also the capital of Vizcaya, a province (like a county in the U.S.) that belongs to the Pais Vasco region. This is a popular place in Europe Paul, perhaps you have customers there...
Strange question. The only difference is that one is controlled by the volume switch and you can turn the volume up and down. The other has full volume and used for EQ. or recording as the cassette plays. and things that must have full volume.
I wanted to ask maybe you can help you know a lot when it comes to audio , what’s the difference on the following : when I connect a external phone or via Bluetooth to a car amp or stereo I get less overall volume on the speakers but when I play cds or fm radio the head unit sounds louder , I also wonder for example putting the output of a line out of an instrument like piano / eléctric perc what’s the db or ac micro volatge output aprox or “value “ if I were to connect that to a home stereo mic or line input how much will audio level be affected , of course the only use should be a mixer that has gain and all to EQ but why can’t this three areas in sound be 1? 😂 In car audio I believe the best output in ac can be upto 5v ac aprox but in a pink noise test no distortion 1% , so but I don’t know the terms used for each of this areas or how to call those different values 😅
Sir I have an integrated amplifier named Cambridge audio sr10 but it doesn't have preamp out Can I take out the preamplifier output connection from the amp before it goes in to power amp section. Please let me know
Any practical demonstration of getting line out from tape recorder that doesn’t has line out because i want to convert audio songs from cassettes to mp3s and finally discard those cassettes... What would be the circuit diagram and what additional components are required i think a capacitor and a resistor but of what value? I want to get optimal output out of the tape recorder for optimal conversion
@@kenbongaards554 thanks for the reply but the sound from the headphones is not optimal... The sound from line out is constant and of optimal fidelity and quality... This is what i experienced...
Most ordinary preamps made after the middle 1970s, whether separate or built into receivers or integrated amplifiers, lack buffers ahead of the tape outputs; the signal passes through the selector switch and goes directly to the recording jacks. (Built-in phono preamps may appear to be buffered, but not all of them really are.) After the tape monitor switch, there are usually series resistors (most are between 4.7 k and 25k; some are higher or lower) that feed the stereo/mono switch if there is one (and there Should be!); those resistors prevent the two channels of low-impedance sources from loading each other down and causing distortion. A quick look at the service manual for almost any unit will reveal the truth of this.
@@jonathansturm4163 Ah yes, I also have some pots for musical enhancement. A motorized pot for volume, so that I can use a remote to attenuate the volume in an analogue manner. Schiiit products are good (sounds like a paradox, somehow hehe), but I use an SPL Phonitor 2 as a preamp. It also has a headphone amplifier and headphone matrix built in. The matrix allows you simulate the sound of speakers into headphones, like sound angle, phase (to simulate room modes) and even things like interaural time differences (which Paul calls "interaural crosstalk").
If I understand your question correctly then yes,. The output of a microphone preamplifier or an EQ should be line level and that can go into most preamplifiers.

great garden, plant marigolds with your veggies for a real great crop
Loved that part where you said I love tomatoes. Haha
😜Me too.
Love the way you guys did the step garden . Looking great ! ♥️✌️
Your garden is bigger than my backyard😆
Everyone's talking about your tomato's, I'm watching closely to see where you're growing your weed...😜
Playing psychedelic music on some preamps makes them smoke their pot!
DOH!
Unless you have a preamp or receiver with individual input level adjustments, it's important to understand that line out level will depend on the selected source. The range between low-level and high-level sources can be 15dB or more.
There can also be a significant difference in the output impedance. For example, my old Pioneer receiver has over 2K ohms output impedance at its line (record) outputs, but the preamp out is less than 300 ohms. The lower output impedance reduces noise susceptibility, and avoids high-frequency rolloff if you use very long cables. The higher output impedance is only intended to drive relatively short interconnects, typically 2m (6').
@behexen250
Recognize this?
Vn = SQRT(4 * k * T * B * R)
Now tell me again, that impedance has nothing to do with noise.
Recognize this?
Vn = Z * In, where Vn is noise voltage and In is induced noise current.
Now tell me again, that impedance has nothing to do with noise.
What does the "VLZ" stand for in the Mackie mixer name 802VLZ, and why does it have that?
I've designed low-noise preamplifiers that achieve 0.5dB noise figure or better. Do you even understand what that means?
"Lower the gain, and you lower the noise." Oh my, what a profound insight! Until you mentioned it, I'm sure no one else in the world had ever thought of that.
Hey, here's an even better idea: Turn the power off, and the noise goes away completely! Magic!
@behexen250
I'll take that as an admission that you have no idea what the noise equations mean.
Since it apparently hasn't occurred to you yet, you can see my employer and job title by searching campaign donor public records - but note that I recently retired. That means I accumulated near 4 decades of design experience as a fully qualified, degreed EE with an aerospace company, designing and developing analog and digital circuitry for flight control electronics, mostly used on Boeing commercial airplanes. First program, back in the 1980's, was the full flight regime autothrottle computer for the 747-200, also used on a few 747-300's, including Air Force 1. It's an analog computer which also employs MSI CMOS logic for mode control and BIT. My design responsibility was updates for control law and interface changes, including a full re-design of the BIT subsystem. Many other programs over the years used my analog and digital circuit designs in actuator control electronics, active stick interface electronics, primary flight computer for the Boeing 777, plus a number of prototype and test equipment designs. I'm certainly not going to attempt listing every design task here.
With regard to what you call "McDonalds level equipment," the Mackie mic preamps come very close to the theoretical noise limit for operation at room temperature. This is achieved by using low-impedance design methods, the importance of which is clearly lost on you.
Fundamentally, optimal low-noise designs must be tailored to a specific source impedance; preamp design is quite different for high-Z sources, than it is for low-Z sources. The mic preamp I designed and built, achieves 0.5dB or better NF with the high-Z microphones it was designed for, but it would not perform as well with low-Z mics.
Your concept of "gain related noise" is strictly user-level, not a term used by analog design engineers. We work with source and component voltage noise and current noise specs, to build representative models and achieve target equivalent input noise (ein) levels and SNR performance. We also employ a variety of methods to protect sensitive inputs from induced noise; I have experience in design for EM hardening in flight controls, as well as commercial audio installations where I have solved a number of noise issues.
@Lloyd Stout
1. It isn't "my" formula.
2. As I didn't provide any examples of applying it, how can you conclude whether or not I understand it?
3. I still have hardware that I designed and built many years ago, and the measured performance agrees with the expected performance that I calculated using that formula.
4. I had to apply that formula for a design project during my analog design class at the UW EE dept., which was checked by my professor. He didn't find any problems with my calculations.
5. That same professor surprised me with an unexpected and stern challenge when I went to pick up my graded final exam at the end of the course: "How did you get a perfect score on the final? No other student of mine has ever achieved that."
@behexen250
The only "issue" I have, is with incessant needlers who keep demanding examples, immediately after I had already provided them.
I will not entertain continued discussion when it has become circular and is unable to progress due to the other party's abject refusal to accept valid evidence. It has happened only one time that I deleted posts under those conditions - and not because of any errors on my part as you attempt to suggest - yet you pose it as though it were a regular occurrence.
And which one of us is making derogatory personal remarks about the other's behavior, motivations and emotions? How does that add any value to technical discussions?
@behexen250
"I take it all back. Stick with preamps, not airplanes. I'm sure your designs are excellent."
You just blew up my sarcasm detector's input stage.
Thanks a lot.
I'm sending you the repair bill . . .
I need help!
What would happen if I was to connect from a pre amp output to a line in?
This is not a problem. Just set the volume of the unit in which you are using line in to the maximum (if it has volumen control, although you can set the second volume control to match its sensitivity to the pre amp output level if it needed) so you can control the signal level from the pre amplifier. I supose that this is your intention.
Best regards.
Mr Paul , can you explain how to connect an AV receiver to another AV receiver? Is that possible?
If the sending receiver has a pre-amp out with a return amp in circuit use a y cable from the pre amp out to split the signal ,one will go in the amp return on the sending receiver and the other send will go to the other receiver on which you could use an aux or tape input
There's a MAGNIFICENT Guggenheim museum/art space in Bilbao. And the BBVA bank, one of the richest in the world, is in fact from Bilbao. Great city in northern Spain. You should visit it. 😉
About the question, great q, I had exactly the same q.
Bilbao is in Spain I think ?
Hello!
I have a Yamaha R-N420D (very basic) receiver which has only 1 'line out' (full powered for i.e. recording). I use this receiver to receive an ethernetcable so I can play flac files from my computer through the LAN network. Next to that I have a Cambridge Audio - Azur 840A V2 which is a way better quality amplifier, but doesn't have an ethernet receiving port. I would like to receive music through the yamaha receiver (ethernet) and send it to the cambridge audio amp which drives my speakers (2x KEF LS50 and 2x Monitor Audio GS20.
Is it possible to use the simple 'full powered - line out' of the yamaha receiver to connect the Cambridge amp and will it sound any good?
Any insights are greatly appreciated!!!
Thanks!
So line out is fixed audio?
Tomato 🍅 + mozzarella di bufala + little bit Origan + Olive oil + Basil 🌿 = Caprese 😋😋😋 now that’s Foodophile 🤣🤣🤣🤣🤣
Bilbao is a town in Spain, Bascony and the place that was demolished by bombarding of German bombers before WWII and Pablo Picasso made famous Guernica painting based upon that catastrophic event.
Sir your videos are very useful.. could you plss tell me is it possible to connect 4 channel amplifier with 4 speakers and one subwoofer ..my car stereo have 4 preout..
Hi Mr Paul,
I have a isd 1820 module. It is a simple record module. The output is a speaker output. How can i make this signal less hot and put a 1/4 jack as a line out. Thanks in advance!
I bought some LPs at a nice record shop several years ago while visiting the beautiful city of Bilbao.
I learned from book by an American that Basque fishermen went to New Foundland even before Columbus mistook America for India. But they kept it secret because the fishing was so good, back then. Where the heck is Boulder?😀
Paul, your terrasses are not properly aligned with your concrete steps. I don't what me noticing says about me.
My question is: Can i connect a pair of subwoofers to preout connectors? Won't burn the imput circuits of the subs? My preamp doesn't have a stereo sub out.
Bilbao is in Spain. It is also the capital of Vizcaya, a province (like a county in the U.S.) that belongs to the Pais Vasco region. This is a popular place in Europe Paul, perhaps you have customers there...
Strange question. The only difference is that one is controlled by the volume switch and you can turn the volume up and down. The other has full volume and used for EQ. or recording as the cassette plays. and things that must have full volume.
I wanted to ask maybe you can help you know a lot when it comes to audio , what’s the difference on the following : when I connect a external phone or via Bluetooth to a car amp or stereo I get less overall volume on the speakers but when I play cds or fm radio the head unit sounds louder , I also wonder for example putting the output of a line out of an instrument like piano / eléctric perc what’s the db or ac micro volatge output aprox or “value “ if I were to connect that to a home stereo mic or line input how much will audio level be affected , of course the only use should be a mixer that has gain and all to EQ but why can’t this three areas in sound be 1? 😂 In car audio I believe the best output in ac can be upto 5v ac aprox but in a pink noise test no distortion 1% , so but I don’t know the terms used for each of this areas or how to call those different values 😅
Bilbao has a fantastic branch of the Guggenheim Museum, designed by Frank Gehry. Check it out!
Hey.can i use sound from one of the speakers in a 5.1 home theater system as a signal to a more powerful sub amp?are there risks involved?
My little British integrated amp has a tape monitor loop. It's 14 years old, though.
Sir
I have an integrated amplifier named Cambridge audio sr10 but it doesn't have preamp out
Can I take out the preamplifier output connection from the amp before it goes in to power amp section.
Please let me know
Any practical demonstration of getting line out from tape recorder that doesn’t has line out because i want to convert audio songs from cassettes to mp3s and finally discard those cassettes...
What would be the circuit diagram and what additional components are required i think a capacitor and a resistor but of what value?
I want to get optimal output out of the tape recorder for optimal conversion
If the said tape recorder has a headphone out try using that with appropriate cables
@@kenbongaards554 thanks for the reply but the sound from the headphones is not optimal...
The sound from line out is constant and of optimal fidelity and quality...
This is what i experienced...
Hello Adam could I install a effects loop to my tube amp that doesn't have one, it only has a line out and a head phone jack? Thank u for any info
I just got the Black Voice witch is an amp and a preamp. But the line out first say pre out.
Hey Paul I got a question are the speakers in the studio B&w 802s1
bilbao is in spain!!..they have a good well not so good football team atletico de bilbao!
Thanks from someone that has lived and studied in Bilbao.
I found this very helpful. Appreciate your channel 👍
Line standard is simply 0.78v (0dB) into 600 Ohm load, it can be balanced or unbalance.
Bilbao is in Spain 😊
Too bad the tomato growing season is so short in Boulder... Last year I needed to pick all of my tomatoes green because of an early freeze.
Northern Spain!!!
I too was wondering about the answer to this question. Thanks.
I love tomatos, too! Especially those tiny cocktail tomatos!
Most ordinary preamps made after the middle 1970s, whether separate or built into receivers or integrated amplifiers,
lack buffers ahead of the tape outputs; the signal passes through the selector switch and goes directly to the recording jacks.
(Built-in phono preamps may appear to be buffered, but not all of them really are.)
After the tape monitor switch, there are usually series resistors (most are between 4.7 k and 25k; some are higher or lower)
that feed the stereo/mono switch if there is one (and there Should be!); those resistors prevent the
two channels of low-impedance sources from loading each other down and causing distortion.
A quick look at the service manual for almost any unit will reveal the truth of this.
Came for the line out explanation, stayed for the tomatoes
💪💪💪 nice garden
Bilbao is in Spain.
Hi Paul, would that also work with an AV receiver?
Hi ,Paul love your garden setup .
Portugal
1:53 Plenty devices still use pots for signal attenuation.
My Schiit DAC uses a pot for that very purpose. And I use pot for pain attenuation with the side benefit of musical enhancement ;-)
@@jonathansturm4163 Ah yes, I also have some pots for musical enhancement.
A motorized pot for volume, so that I can use a remote to attenuate the volume in an analogue manner.
Schiiit products are good (sounds like a paradox, somehow hehe), but I use an SPL Phonitor 2 as a preamp.
It also has a headphone amplifier and headphone matrix built in.
The matrix allows you simulate the sound of speakers into headphones, like sound angle, phase (to simulate room modes) and even things like interaural time differences (which Paul calls "interaural crosstalk").
@Fat Rat It Shure is! 👍
@Fat Rat It Shure is stylus!
Just like other fancy Elactric devices 😉
@Fat Rat Yes, Shure is that Elac-tronics brand 😜
Bilbao is in northern Spain , the largest city in Basque country . That was a great question . I only thought I knew the difference .
Bilbao is beautiful!!!
Glad to learn that from you now looking more like a farmer...
Can I connect a microphone preamp or a guitar equalizer to a line level input of an audio interface which does not have a built-in preamp?
If I understand your question correctly then yes,. The output of a microphone preamplifier or an EQ should be line level and that can go into most preamplifiers.
in Spain?
thank you very much Mr Paul!!!
Great video glad to listen to your opinion really helps
