Sonodore Pre-amplifier MPS-502 for: RCM-402, CCM-65, BLM-21

2 Channel Microphone Pre-Amplifier / combined 60V Power Supply.
This unit combines the MPA-502, 2 channel Microphone Pre-Amp, with the
PS-402 Power Supply.
There are 2 advantages, namely only one box for power and amplification, and
secondly, the unit is dedicated to the Sonodore microphones, so we could leave
out the standardized DC-de-coupling capacitor necessary for most 3rd party
pre-amplifiers. This capacitor normally is integrated in the PS-402.
The result is a substantial better impulse response and even lower distortion.
The MPS-502 get’s the ultimate out of the Sonodore microphones in our
experience and vision!
