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!

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.
