VCA Control Module

D-984VC

The D-984VC is a dedicated VCA control module designed for use with the D-901 Digital Mixer. It expands the D-901 Digital Mixer's functions by 20 VCA control inputs, 8 contact inputs, and 8 contact outputs. By the VCA controls from external equipment, this module permits the D-901's gains of 12 inputs and 8 outputs to be controlled. By the contact input controls from external equipment, this module permits the preset memory recall, input/output channel gains, stereo input selection, and channel ON/OFF to be controlled. By the contact output controls Tally outputs can also be provided for external control.
