2-Channel Remote Speaker Station with Gooseneck Mic Connector
KB-702GM
The KB-702GM remote speaker station permits the user to select between two channels of partyline communications, with the ability to talk and/or listen on the selected channel, like the KB-702 but adds a gooseneck mic connector and VOX circuitry.
Note: Access the Encore Power Supply Calculator to estimate power requirements for analog partyline systems.
