AUSTRALIAN MONITOR ACM1202P User manual

120W + 120W
Dual Channel Power Amplifier
ACM1202P
Description
The ACM1202P is a dual channel 120W + 120W power amplifier designed to deliver continu-
ous full range performance in a compact and reliable package. The ACM1202P is two inde-
pendent amplifiers in the one chassis making it the perfect choice for multi-zone or multi-chan-
nel applications.
Inputs and Outputs
The ACM1202P provides dual balanced XLR inputs (male and female) per channel. These two
inputs are wired in parallel enabling a line level “split” to be taken from the second input of
each channel.
100/70 volt line and 4/8 ohm outputs are available via the rear panel barrier strip.
Controls and Metering
A recessed input attenuation control for each channel is included on the rear panel. These pots
are accessible using a screwdriver.
The ACM1202P features a signal-present LED per channel and power-on LED.
Protection
The ACM1202P features ”slow start“ and dual AC and DC fuse protection. Also featured is
automatic speaker protection. The ACM1202P includes generous heat sinking for reliable
operation in even the most extreme conditions.
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.
