Hi guys!

I'm happy to introduce you my new MP312-4!
 
For a while I wanted to create a Rack version of API312 mic preamp with 4 channels.
I'm sure people will love it and will be using different Rack modules. It was my idea to create something exciting!
I hope you will love this new MP312 4 channel mic preamp since it was made based on old API 312 version preamp.
And now you can use four channels per unit! I hope it will be a good reason to select this kit.



Price: 250$ + shipping!

Will be redy for shipping from 15 of November!

More information on WWW.AVDAUDIO.COM

Hi, I would like to order one of these.  Does it include transformers?  How would you describe the difference between 1731 and 2520 opamps?

Hi rockinrob86,

The MP312-4 DIY kit contains:
Metal case (with screws kit)
Metal case for power supply
PCBs (Main PCB and PCB for power supply)
Power transformer (115V or 220V included)
Four ps of GAIN potentiometer 
Four T-Pad 600ohm attenuator
DOA PCB (4ps of 2520 or 1731)

Audio transformers are not included! To order separatly!

1731 and 2520 has small difference. 1731 has more clear sound, It is my opinion. But 2520 more deeper in the mid range.

Hey Andrey,
Does the 312 BOM include the components for the 4 DOA PCBs ?

Thanks ;)

dasnevestheo, hello!
312 kit has only PCB of DOA. I can add as a bonus two different DOA.
But if you need full DOA's kit, you must to order it separately!

You are welcome!

Hi,

do you have a mouser cart for the 312-4 bom ? I must admit that it would be very helpful and a big time saving. Or at least, do you have an estimation of the cost for the bom components ?

Cheers

I was going crazy trying to find out why my MP312 build is blowing caps

Come to find out the pcb has a white stripe on the anode of the electro cap footprints for some bizarre reason

For people like me who are too stupid to read the microscopic + and - on the footprint, the cap should look like its backwards

I’ve been playing around with my newly built MP312 pair this weekend and I’m really happy with them.

They sound and look great. Very nice work, especially with the transformers
