ACM250 250w Mixer Amplifier Operating Manual
ACM250, 250 Watt Mixer Amplifier Product Description The ACM250 mixer amplifier is designed for commercial installations. It operates on 230/240 VAC, 50Hz (or 115 VAC, 60Hz with factory modification) and may be desk or rack mounted (rack mount kit supplied). The ACM250 delivers 250 watts into a load of 4 ohms, 70 or 100 volt line. As standard, the ACM250 is supplied self standing with rubber feet. They may be stacked to a maximum of four units high. .
Power Switch This switch controls the switching of AC power to the amplifier. A blue On LED will indicate whether the amplifier is switched on or off. Protect LED A feature of the ACM250 is high temperature protection. In most applications, the internal cooling fan will most probably never switch on. When used with demanding speaker loads or in difficult operating environments, the fan may regularly switch on to cool the amp down and then switch off again.
Phantom Power This button enables or disables the 18 volts DC phantom power which is available on all microphone inputs (XLR’s). The “in” position indicates that phantom power is on for all mics. The “out” position means that phantom power is switched off for all mics. Phantom power is required for electret condenser microphones which require DC power to operate.
