Multi-channel Volume Control control module kit

A kit that includes all the parts needed to build the control and power supply module for the Multi-Channel Volume Control, including the LCD touchscreen. You can connect up to five Volume Control modules to this to control the level of up to 20 audio channels (16 if an OLED Module is included).

See the link below for details on everything included in this kit. A 1m length of ribbon cable is included to connect the various modules in the system.

You will also need at least one Volume Control module. That kit is available separately, as is the optional OLED Module.

Note: the photo shows the fully assembled module.
