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.
