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

Got myself some Mic preamp module (from eBay) originally for a Sony MXP3000 console. For more information about the Sony MXP-3000 Mic Preamp, click here. http://www.wesdooley.com/z-p/Sony_MXP3000.html

I'll be racking this mic preamp (and EQ module), adding power supply and XLR connectors.

Gain is 15 to 35db in the LOW setting, and 30 to 65dB in the high, plus 48V phantom power.

In action, along with his buddies.... The EQ module is right below the mic preamp module.

TESTING:
My problem now is how can I test this mic preamp if it's working or DOA?  The seller didn't know much about these things, so I'm left on my own.

I found a drop-in replacement preamp module for the MXP-3000 console (thanks Google!) made by the John Hardy Company.

Upon closer inspection of the above drawing, I see that the pin-outs are labeled. If the John Hardy MPC-3000 is a drop-in replacement, then my MXP-3036 preamp should follow the same pin-out assignment.

So I soldered wires to the pin connectors, added XLR inputs and outputs, and used my bench power supply to supply +18-0-18V. Hooked it up to my studio patchbay, and it passed audio!

Yipee, it works!!! This could be the best $35 I've spent.
