User manual AUSTRALIAN MONITOR DCM500 DATASHEET

[. . . ] Description The DCM500 is a high performance 500 watt power amplifier designed to meet the needs of the most demanding sound reinforcement installations and applications. The amplifier is designed to operate from both AC mains power as well as 24 volts DC. 500W AC/DC Power Amplifier DCM500 Inputs and Outputs The DCM500 features a transformer balanced line level XLR input with a parallel output to feed additional power amplifiers. [. . . ] The DCM500 features generous heatsinking and fan cooling. The fan will only switch on if the operating temperature exceeds a factory preset level. Australian Monitor Installation Series amplifiers feature a protection network that provides greater stability and performance. Our amplifiers are recognised worldwide for their reliability and this is due to the extensive levels of current limiting which protect the amplifiers from both overload and overdrive conditions. Other Features The DCM500 can operate from both AC and 24V DC and includes a built-in trickle charge circuit.
