This module replicates the Moog 992 Control Voltages with four CV inputs and internal patching for driving Behringer 904A and 904B filter modules. The module is designed to reduce the need for patch cables and to replicate the CV internal bus structure of the original Moog Modulars.
The module AM992 is supplied with PCB Daughter Boards that attach to the rear of the 904A and 904B and a cable that interlinks them with the AM992.
