ACM250P 250w Power Amplifier PROTECT SIGNAL ON POWER Operating Manual
ACM250P, 250 Watt Power Amplifier Product Description The ACM250P power amplifier is designed for commercial installations. It can be used for either low impedance (4 ohm) or 70v/100v line speaker systems. It operates on 230/240 VAC, 50Hz (or 115 VAC, 60Hz with factory modification) and may be desk or rack mounted. The ACM250P features a line level input (with parallel output) and is normally used with mixers, mixer amplifiers or other power amplifiers.
Rack Mounting The ACM250P is supplied with rack ears attached to allow mounting within a standard 19” equipment rack. As is the case with almost all audio products, adequate ventilation and air flow is required. When installing multiple ACM250P power amplifiers within the one rack, it is recommended that at least one rack unit of ventilation space is left between every two amplifiers. For table or shelf mounting, the rack ears can be removed using a screwdriver.
XLR Audio Input and Parallel Output The ACM250P includes both male and female 3 pin XLR connectors. While the female is normally used as the input to the amplifier, both XLR’s are connected in parallel so either will work. When signal is connected to one XLR, the other XLR becomes a line level output allowing the input signal to be distributed (split) to other amplifiers. In some projects, the same input may be looped through to multiple amplifiers using this method.
