Moog 992 Control Voltages


The Moog 994 is a very simple 1U module for CV routing only to the 904A Low Pass Filter in the upper cabinet.  

The Moog description of this module is:

The 992 Control Voltage Panel is used for routing control voltage signals (generally from Keyboards and Ribbon Controller) to filters and upper console modules in larger modular systems. The fourth input on the panel face contains a signal inverting attenuator circuit.


The date on the label is 2 years before the Sytem 55 was assembled.


This is a very small PCB containing a simple inverter for the reversable CV attenuator.  The PCB still uses the separate edge finger PCB.
