The Baldwin Boxall BT8 8 zone telephone extension interface allows connection of a telephone system to a public address system via a conventional two wire telephone extension socket.

The BT8 detects the ringing current then allows the user to broadcast a message via their desk telephone. 

The BT8 enables the user to pre-record an announcement, thereby reducing the risk of feedback where the telephone is adjacent to a loudspeaker.

When connected to a telephone system with MF signalling, the BT8 enables the user to select up to eight zones via the telephone keypad.

Free standing and self-powered.
