Millennia HV-32P Portable Two Channel Microphone Preamplifier
The Millennia HV-32P is a portable two-channel microphone preamplifier with continuously variable gain, a ribbon mode, and phantom power, running on 12 to 15 V DC.
Gain runs from 14.5 dB to 60 dB and rises faster near the knob’s full clockwise position, for low-level signals. The Ribbon-Dyn mode DC couples a ribbon or dynamic microphone to the gain stage and adds 10 dB, for up to 70 dB of gain. A microphone that needs phantom power does not work in this mode.
A switch turns on +48 V phantom power for condenser microphones, and the pad cuts the signal by about 14 dB after the gain stage. Signal LEDs light green at -30 dBu, yellow at +8 dBu, and red at +20 dBu.
Equivalent input noise is -130 dB at 60 dB of gain, and the frequency response runs from under 10 Hz to over 200 kHz.
