Home > Studio Recording DIY Projects> Sony MXP-3000 Mic Preamp

My Impressions:
Very quiet.... very clean and clear sounding. It's a 100% solid state design. As you can see from the picture, it's a simple design. Not much there to muck up your sound. Very good amplification. Lots of gain!... it can get pretty loud.

Puts my ART DPS preamp to shame... I like this MXP preamp!

UPDATE: New MXP preamp with transformers

I found some MXP preamps that are different from the above model. This new one that I found uses mic input transformers from the company Jensen-Transformers (www.jensen-transformers.com) Here are some pictures!

The transformer can above.... Model # is JE-115K-E.  This particular model I believe is now replaced with the JT-115K-E model on their website.

You won't believe this! But this particular model of the Sony MXP preamp is using a Texas Instrument NE5534 dual opamp.

So let's see... a common NE5534 opamp, and a Jensen Transformer, this thing will be easy to clone!!!! When I get some time, I'll try to sketch/trace the schematic using the PCB layout.

A whole body closeup of the preamp module. Very simple isn't it?

This is the other MXP preamp I have. Notice the difference. This particular model does not use any transformers and uses a proprietary discrete opamp circuit.

My three amigo preamps! (2) Transformer type, and (1) discrete opamp type.
