VC2.1 Volume Controller

The VC2.1 DCS (Delta Control System) volume controller is a device designed for remote volume control of six independent audio channels. It has a function of simultaneous muting of all channels through the MUTE function.The controller adjustment is realised through the RS 232 serial port.The operational state of the individual channels is signalled by the LED diodes, placed on the device front panel. The particular LEDs signal the power voltage presence (POWER) and the controller channels state (CH1-CH6).  

The rear panel contains all device connectors:

- audio channels inputs and outputs,
- power connector with the external mute terminals DB9 socket for the RS 232 control connection.
