Spectra 1964 Model V610 Complimiter

Spectra 1964 Model V610 Complimiter is the top specification of the 601-based processor: lower noise, higher output and less distortion than the other models in the range. Control is by Elma stepped switches with mil-spec resistors.

Settings you can recall exactly

In mastering a continuous pot is a liability: a week later you cannot land on the same position, and left and right channels never match perfectly. Elma stepped switches solve both at once, because a setting is stored as a detent number and both channels can be set identically.

Headroom for work on the mix bus

Maximum output of +24 dBu and an input pad offering -10, -20 and -30 dB let the V610 sit in a hot bus path without overloading the input. Response within 0.1 dB from 20 Hz to 40 kHz and THD under 0.01% at +22 dBm with up to 30 dB of compression mean the unit controls dynamics without editing the tone. Beyond mastering it holds up equally well in tracking and mixing.
