AUDIO TELEX ACM250P Specifications
Text of the manual
The ACM250P is a 250 watt power amplifier with outputs for 4 ohms, 70 and 100 volt line. It may be desk or rack
mounted but is packaged as self standing with rubber feet. The ACM250P features a flat screwdriver accessible
gain control on the rear panel.
Inputs
The ACM250P features two signal inputs. The unit has industry standard 3 pin XLR microphone sockets. Two line level
sockets are provided for bridged in/out connection.
Outputs
The ACM250P features 100 volt, 70 volt and 4 ohm isolated transformer outputs.
Protection
Internal current limiting protects the amplifier from both overload and overdrive conditions. The ACM250P also
features protection in the form of excess temperature auto cut out. An in built auto temperature sensing fan will
turn on at a factory default level but in most situations, will never be required.
Manufacture
The ACM250P is proudly designed and manufactured in Australia.
