ITC T-450B เครื่องขยายเสียง 450W. Mixer Amplifiers 450W Public Address
Mixer Amplifier XLR Balance Mic input + Phantom Power
The basic public address mixer amplifiers have power ratings from 30W, 60W, 120W, 240W, 350W, 500W to 650W. They are featured of 3 balanced microphone inputs, 2 aux inputs and 2 EMC inputs.
Priority muting is achieved via EMC1-2 for overriding other inputs except Mic1 on front panel. Individual gain controls are provided for Mic 1-3 and Aux 1-2, bass and treble controls and master volume control are provided for overall tone control. 70V, 100V and low impedance 4-16ohms speaker outputs are provided. Extensive protection from short-circuit, overload and high temp.
