RDL EZ-MPA2 Dual Mic Preamp
« on: January 18, 2011, 07:36:35 AM »
Anybody familiar with this company or piece of gear?
"Made in USA"

There's one on Ebay right now with $139 BIN.

24VDC powering is less than ideal in the field though.

EZ-MPA2 Dual Microphone Preamplifier - Stereo Output with Compressors


    * Left and Right Balanced XLR Microphone Inputs
    * Switch-Selectable Phantom on Rear Panel
    * Unbalanced Output on MINI or RCA Jacks
    * Input and Output Connections on Rear Panel
    * Front-Panel Compressor Enable/Disable Switch
    * Audio Compressors Control Overloads
    * Front-Panel LEVEL Control for Each Channel
    * Dual-LED VU Meter for Each Channel


    * Optimized for Dynamic or Condenser Mics
    * Headroom Accomodates High Input Levels
    * Headroom Increases with Lower Gain Settings
    * Compressor Limits Clipping Over Wide Dynamic Range

The EZ-MPA2 is a stereo microphone preamplifier with front-panel volume controls and audio level metering. A front-panel switch engages audio compressors to control overloads and clipping during high level audio bursts or peaks from the microphones. Dynamic or condenser microphones are both supported with rear-panel switchable phantom voltage. The line output is available on RCA or MINI jacks. Left and right channel LED VU metering facilitates easy level adjustment. The EZ-MPA2 is ideal to add microphone inputs to mixers and amplifiers with line inputs. It is used in houses of worship, restaurants, clubs, meeting rooms, educational facilities, conference rooms, studios and commercial sound systems.

IN that price range I'd say the Little Box is still a better choice.  You are right powering options are very limited for this.

I was checking out their DAC a while back for home playback.  It's a shame the ADC and the pre require 24v, though.
