Adapter for Dispatcher/Operator board with screw terminals for mic input and line level output and/or modular jack for audio output.

This adapter allows you to connect 3.5mm tip/ring/sleeve audio cables to screw terminals (for input and output) and also offers a modular connection for the output. This is intended for use with scissor mount candlestick phones as microphones (there is a mod available for the Dispatch/Operator board to support carbon mics) and various speakers, including telco-style 106/107 self powered speakers with screw terminal or modular connections.
