DON Classics NV73

DON Classics NV73 is a pre-amp for the 500 series.

Official description
Overview


 * 0dB line setting to warm up your digital recordings while mixing
 * Output attenuator allows more sound options
 * Impedance switch lets you choose 300 ohms for your old ribbon mics
 * DC-DC converter to change the +-16V(32V total) to 24V so the module just sees a clean single 24V rail.
 * Slow start circuit, meaning the module never uses more than the 130mA allowed. Even inrush current stays below 130mA.

Specs


 * Input (incl. Line setting) are transformer balanced/earth free
 * Microphone Input: Gain 0dB to + 65db in 5dB steps. (around 71dB with Lo Z button pressed)
 * Mic Input impedance: around 1200 ohms normally; or 300 ohms (with Lo Z pressed)
 * Output: Maximum output is >+26dBu into 600 ohms.
 * Output is transformer balanced and earth free
 * Output impedance: Around 50ohms
 * Freq Response: +0dB/-0.5dB 20Hz to 20kHz.
 * ±16 vdc converted to single 24V rail inside module. Total current draw 125mA max
 * Output pot: unity at CW, mute at CCW. -6dB at midpoint
 * Polarity flips 180 degrees when pressed in
 * Phantom 48V applied when in down position.
