Modding my Yamaha MC2404-II mixer - Part 1 - Before the mod
Вставка
- Опубліковано 17 чер 2016
- In part 1, I do a preliminary test on my Yamaha MC2404-II mixer. I record a mixing session without EQ and again with EQ applied. Once I've finished the mod, I'll once again record a mixing session without EQ and again with EQ applied.
And finally, in the last part of this video series I'll compare the mixer before and after the mod, side by side so we can all perform a critical listening test to see whether a project such as this mod is even worth the money and effort.

I have the 1604ii console at my studio (: . Love the preamps
I have one also and love the pre also
This video helps to demonstrate by purchasing or acquiring a use mixer can be a laborious task in replacing components. The better way to test is to supply various frequencies using a frequency generator and an oscilloscope to actually see the output - before and after. The difference from before and after may not have an impact on quality output but that the tolerances are better, therefore the adjustments, for instance on EQ, or flat settings would be different.
hi! how can I mos the auxs for being all pre fader? thanks
Thank you for your beautiful video. Can you help me understand how you connected the mixer to the computer and have the tracks
All channels coming out of the DAW go out of my 3 audio interfaces (connected via ADAT digital outputs). They go out of the audio interfaces via 1/4" analog and into the mixer. The mixer 2bus comes out analog and into my line inputs on my main audio interface and into the DAW.
May Yahweh bless you and I love this mixer I just bought one off Ebay for 300.00 and 185.00 shipping I do believe that the price is going to go up in years because they don't make them like they use to.
Question. how did you plug this mixer into your computer. how did you get it to come through into your computer
I sent the stereo output bus to two line inputs on an audio interface.
I recapped my mc 2404 mk1 in the power supply and the audio path of all the channels. I also added direct outs to all the channels.
How difficult is the direct outs mod? I'm actually pretty interested in this because if I get a really nice AD/DA converter, I'd need pre-amps and this board would be pretty dope for that.
+Misc. Factory Studio if you have a schematic it's pretty stair forward. I taped into the signal just after the faders. Then drilled a hole on each channel just below the insert and line in jacks. Time consuming but not difficult.
+TheBlack Moriah sorry strait forward lol.

Cool thanks for sharing!
My mixer has two 1/4" jacks just above the XLR inputs (preamp). One of them is a Hi-Z input and the other an insert jack. I'm wondering if I could steal the Hi-Z jack since I don't think I'll ever use it.
I have the owner's manual that has a schematic. It's not very detailed tho. I'm pretty sure it doesn't have any opamps or caps indicated in the schematic. I've looked it over a lot to try to figure it out.
My worry is I don't want to screw anything up, and I would have to have pictures of a successfully modded mixer (line outputs mod) to guide me as well as all the specs of the material used (if there's a specific gauge wire to use, parallel and series wiring, etc.). I'm really good with soldering, great with understanding things, but I just need a good guide to make me comfortable to go ahead with the mod. I also prefer not drilling anything.
How do you feel about Yamaha m916 mixer
How's the mod coming along? The 275's are the opamps btw.
Yeah I just blanked in the video for some reason, remembered they were opamps after I recorded, lol. I did a bunch of testing in steps, doing one set of four and the entire master section before doing all 24 channels... turns out the mod did absolutely nothing, no difference whatsoever. I'm going to do a follow up video and show my results.
Can i show me how you connect Mixer .2404 to computer
I connected each output on my audio interfaces to the inputs of the mixer. Then the stereo bus outputs from the mixer to the inputs of the audio interface for recording.
@@VintiqueSound Which audio interface do you use?
Don't buy chips off ebay. They willl be counterfeit and usually wont work. Sorry. Buy some cheap Panasonic FM/FC series capacitors, recap and double up all of the capacitors uF rating in the signal path of your channels.
Yeah I'm a total noob when it comes to this kind of upgrade. Is it ok to double up uF? Would I have to compensate for that increase by doubling up the power supply or changing resistors or something of the sort?
Either way, I'm not going to do any mods to this or my other analog mixer except for maybe installing direct outs from the preamps so I can go directly to an AD converter and ditch my bundle of interfaces.
Start off with one channel. It wont make much of a difference on the power rails if you only upgrade 1 channel. See if you like it with new caps. Yes you can easily upgrade all the capacitors in the channel to double the uF. Buy a big batch of panasonic FM/FC caps from farnell or some shop like that.. they cost next to nothing.. your tone will probably be hell of a lot cleaner and bass will come back
I wouldnt however upgrade with those chips. Especially if you dont know if theyre legit or not. Opa275 takes a lot to get stable and if you dont know anything about stabilizing opamps i would stay away.
Hmm, I don't know anything about stabilizing. I'll probably just stay clear of any upgrade. Also, I've just completed a thorough test between analog summing versus digital summing (Cubase) and found almost no difference at all when loudness and panning was accounted for. So I'm pretty sure my analog mixer is as clear as it's ever going to sound, modding it would probably simply change the EQ curve, but having it sound very similar to digital summing seems just perfect to me :) Thanks for the details!
