The T-120B is a basic public address mixer with a 120W power rating.

The T-120B features 3 balanced microphone inputs, 2 auxiliary inputs and 2 EMC inputs.

Priority muting is achieved via the two EMC inputs which can override other inputs except the front panel microphone input.

Individual gain controls are provided for all microphone and auxiliary inputs alongside master volume bass treble controls for the entire unit.

70V, 100V as well as low impedance 4-16 ohm speaker outputs are also provided.

The T-120B features extensive circuit protection with built-in protection from power shorts, overloads and high temperatures.
