- What is the difference between -10 dBV and +4 dBu? In this video, you'll learn the difference between professional and consumer audio line level.
CORRECTION:
The difference between +4 dBu and -10 dBV is 12 dB.
(In the video, I said the difference is 12 "dBu". When drawing a comparison between two values, dB is used. "dBu" is used only when comparing a voltage to 0.775 volts.)

Amazing watch! You simplified the contrasts between Consumer & Professional gear quite elegantly :-)
Keep up the good work.
Thanks, Aaron! I appreciate you watching!
Another excellent explanation, thanks! I was curious about the 0.775V standard because I know it isn't the square root of 2 or anything obvious like that! So I looked it up on Wikipedia. Turns out it's pretty arbitrary and seems to have historical roots in telephony:
"In professional audio specifications, a popular unit is the dBu. This is relative to the root mean square voltage which delivers 1 mW (0 dBm) into a 600-ohm resistor, or √1 mW×600 Ω ≈ 0.775 VRMS. When used in a 600-ohm circuit (historically, the standard reference impedance in telephone circuits), dBu and dBm are identical."
Bravo ! Great explanation my friend, i found a lot of value in this video. You just earned yourself a new subscriber. Peace !
Kyle, your videos are the best in the entire field. congrats.
Thanks, Thomas!
Great help! Building a sound system atm! 4 bassbins, 2 kick bins and 2 mid tops. 4 band system. How to I work out what to set my DB at for each channel on my xover going to each amp
Why UA-cam suggest your chennel to me so late!!! Your video is all I want for all time!!!!
Thanks, @Mashed Potato! I’m glad you found this channel! Any other videos that you’d like to see?
Great videos! Simple and clear
Glad you like them! Thanks, Ruben!
Still not sure if I should set my new JBL 305 PMkII to +4dBu or -10dBv with my also new MOTU M2 thru the balanced 1/4 out to XLR in.
Hey did you figure it out?
Just got used to it.
So I have my jbl mk2 series 3 speakers connected to the back of my scarlet pro 2i2 but the back of my speakers has a setting for input sensitivity +4 db or 0 my teacher said +4
What are some examples of when consumer and professional gear would be interconnected as part of a single system?
I've never really thought of my guitar amplifier as being either a professional or a consumer device.
Great! Simple and informative! Well done!
Thanks, @Dimitris Kovaios! I appreciate you watching!
Informative as always. Thanks
Thanks! I appreciate you watching!
So what happens if you connect a professional cd player to a consumer receiver? And what is the difference in quality in comparably priced pro & consumer cd players? -- good video btw!
should a mooer ge300 multi guitar fx processor be select as professional audio level or consumer level
On the Behringer Xenyx analog mixers (e.g. X1204USB) there's a level switch button next to the inputs on the stereo channels. It reads -10 and +4. On the manual, it says that the -10 setting makes the inputs more sensitive.
Let's say I'm connecting my iPhone or MacBook to stream music through these channels. Should I use the -10 setting, as iPhones and laptops are consumer products?
I won't lie, these two level standards make me confused... Thank you to all who will help me!
Is that also why, in audio editing software, you can have a maximal increase of 12 dB at a time? It would bring the volume up for use by the professional equipment in one iteration of amplification, it seems.
Hi and thanks for great video. I am trying to use a pair or genelec 8010 monitor speakers together with Zoom F8n audio interface.
F8n main output level settings:
Line (+4dBu)
Normal (-10dBV)
Genelec 8010 sensitivity settings:
OFF(default): 100dB @ -6dBu
ON (-6dB): 90dB @ -6dBu
I get a huge amount of noise using the Line level on F8n and default sensitivity settings on Genelec.
I get better results using "Normal" on F8n and "ON" on genelec but still I can hear noise.
What am I doing wrong? Do you have some advice?
If I use a CleanBox between a pro amp and a consumer AVR, what voltage shoud I set the amp to?
Finally a really explanation.. 😊
Glad it was helpful! Thanks for watching, guitarans!
It’s not common I know but let’s say since it’s possible , what’s the difference in audio signal level of a car audio stereos / car amps output rca and or against a pro mixer or mini Bluetooth line input connector signal level ? What’s the difference of this all levels my questions comes from a test I did on connecting a 3.5mm phone Jack output and I connected this to car amp but I always noticed the Bluetooth built in car stereo always sound abit louder than an external or when using my phone as a source and putting that audio to my car amp or stereo it reduces a lot of speaker output but when the music is being played by cd of fm is way louder . In mixer there no issues if I use any source like phones or external Bluetooth the gain can help me adjust . I hope you or someone can help me it’s audio but different worlds heheh
Thanks for the informative video!
Thanks, Scott! I appreciate you watching!
Thanks a lot for the info, it's exciting to learn with the videos on this channel. I have a doubt, I want to connect a mixer to an avr receiver (marantz SR5013), but I'm not sure if it'spossible and in this case which outputs I should use, if the main out (xlr or trs) or tape out (rca)?? SR5013 specs indicates 200mV as input sensitivity, which according to my calculation would be -14 dBV, which is even less than the -10 dBV of the tape out, that I think is the lowest voltage signal output of the mixer... Maybe I should just lower the main mix fader below unity, rely on headroom, or just be careful not to turn the AVR volume too high, I don't know... by the way my front L /R speakers are 4 ohm, I don't know if it's relevant for sensitivity and levels... I would appreciate any indication. Greetings!!
I’d recommend using the RCA outputs as you’ve described, Martí!
I have a Focusrite Scarlett 2i2 3rd gen and JBL lsr 305 mk2 studio monitors. I tried using the +4 dbu setting, but the signal was too soft. Why is this?
I'd recommend making sure that the signal sent to the interface is strong (around -6 dB peaks or greater). Also make sure the volume knob on the monitors is set properly.
Hi,
(1) Is it okay to connect the output from a 50-watt guitar amplifier headphone port to a line-in input port on a mixer?
(2) Also, is it okay to connect the output from a 50-watt guitar amplifier headphone port to a line-in input port on a PC sound card?
When I did (2) the PC sound card quite literally got fried up.
But for (1), the mixer didn't get burnt up and everything functioned normally.
What's the difference actually between the two scenarios?
Afterall both had the same signal from the headphones output port going into a line-level input port.
Hi, I have a question, what if I have a USB audio interface and studio monitors speakers (JBL 308mkii) should I set it to +4dBu or -10dBv?
The output of your interface is most likely designed for +4 dBu. You can look in the specifications to verify.
Hi. I just want to know the meaning of consumer audio. I want to buy headphone but the description is consumer audio momentum 4? What does this means?
I didn't understand, does this principle apply to all devices or only when you want to combine speakers with an amplifier? my hi-fi cd player just broke and I was thinking of buying a professional cd player, which would be on an integrated hi-fi amplifier. it's not good? thank you!
Hi! In your jbl monitors connected to your focusrite, do you set the input of the monitors in +4 or -10?? Thankss!!
I have mine set to +4 dBu. I based that decision off of the specifications here: focusrite.com/en/usb-audio-interface/scarlett/scarlett-2i2
The Focusrite Scarlett 2i2 line outputs will output 15.5 dBu at 0 dBFS.
2:00 A signal pad like the one it's used by guitar players?
I just got a Scarlett 2I2 3rd gen. and have jbl 305p mkii's. Should these speakers be at +4?
Yes. I have mine set to +4dBu. The maximum output of the Focusrite Scarlett 2i2 3rd Gen is +15.5dBu.
Hello, i have 2 jbl 308mk2 monitors and the jbl lsr 10s subwoofer connected to my Dj mixer (pioneer Djm s11). Its better to be in +4 or -10? Thanks
I would recommend setting them to +4dBu.
@@AudioUniversity Thanks 👍👌
thanks !!
Your channel I subscribe supporting the knowledge
Thanks, @Leak Banga! Let me know what type of videos you’d like to see in the future!
This is really helpful 🤙
Thanks for watching, Isaac! I’m glad it’s helpful! Any ideas for future videos that you would find helpful, too?
Audio University I have a keyboard synthesizer, how would I go about using that for an at home production, like things I would need and so forth, tutorials on settings that up with software would be nice as well 👍
What do the "u" and "v" mean in dBu and dBv?
Check out this video: ua-cam.com/video/xSe7y9tYex8/v-deo.html
But why is consumer and professional equipment at different levels, and why not use dBV or dBu reference for both?
I don't know the history of it. Maybe it has to do with cost...? I think the different references are used because the numbers are simpler that way. Again, I might be wrong. Good questions, D Young!
There was a movement within the consumer car audio industry back in the 1990s to use a higher line level to better combat noise in the line level cables between the crossover and the amplifiers. They didn't give dBu or dBv numbers, but the marketing said the standard line-level was +-1v, and their system was a +-4v, allowing a 75% reduction in noise within the system. I think they were looking at 2v versus 8v max potential difference.
However, years later, I don't see it mentioned much. Most likely the difference caused a lot of issues, since many people just think everything other than a speaker connection is line level, and don't pay attention to it being a 4v line-level or whatever. So within consumer electronics, it's best to just be the same as everyone else and don't cause problems.
:)
awesome and thank you!
Thanks, @AwesomeJimJam! I appreciate you watching! Thanks for the suggestion!
