Neve 33135 Equalizer & Mic. Preamps

You are bidding on a pair of equalizers. These equalizers feature a
microphone preamp and mic/line equalization. A built in relay switches
from mic to line preamplification. Preamp gain is switched in 5 dB
steps with a handy continuously variable control between these steps.
Leds indicate EQ selection. Mixed discrete and integrated
amplification. High headroom circuitry with using both 24 volts single
polarity and 15 volt dual polarity power. Excellent condition. Working
perfectly. We will provide a schematic with the pin hookups for these
units.
