Referee Audio System

The Referee Audio System is a compact device designed for WRTC referees, providing convenient switching of audio signals between two transceivers. It can also be used as an audio switching device for SO2R (Single Operator Two Radios) operation. It supports three operating modes:

1. Transceiver A only (audio signal from the first transceiver).

2. Transceiver B only (audio signal from the second transceiver).

3. Both (Transceiver A in the left ear, Transceiver B in the right ear).

The device supports processing of input signals in both stereo and mono modes, which can be switched using a switch. A standard 3.5 mm Jack audio connector is used for headset connection, but stereo headphones are required for proper operation.

The device is powered by a 12 VDC source (a 1-meter power cable is included). The 3-meter audio system cable allows the referee to move freely around the operators during operation.
