"Vintage" Version of the A-150. Module A-150 (Dual VCS) contains two separate voltage-controlled switches.

Each switch has a control voltage input, a common Out / Input, and two In / Outputs. The switches are bi-directional: they can work in both directions, so can connect one input to either of two outputs, or either of two inputs to one output.

Voltages in the range -12V...+12V at the O/I resp. I/O sockets can be processed by the module.

Two LEDs show which in / output is active (ie. which is connected to the common out / input).
