250W, 6 Channel Mixer Amplifier
Description
The ACM250 is a 6 channel, 250 watt mixer amplifier suitable for rack or desk mounting. The
amplifier is a self contained compact unit of solid steel construction.
Inputs
The ACM250 has six universal input channels with separate level controls. Each channel will
accept balanced or unbalanced microphone, line and auxiliary inputs. The unit has industry
standard XLR microphone sockets and dual RCA auxiliary sockets for each channel. Line Input
6 has a lower input sensitivity and is suitable for high level CD players.
Outputs
The ACM250 features 100 volt, 70 volt and 4 ohm isolated transformer outputs, plus a tape
recorder output by means of dual RCA sockets. A balanced 700mV XLR output is also provid-
ed to feed up to 6 power amplifiers.
3 Band EQ
The ACM250 includes a 3 band equaliser (Bass, Middle and High), giving the user a wider
range of tone controls for high level music or difficult voice applications.
Tone Generator
The ACM250 comes standard with an in-built four tone generator module. Tones include Bell,
Pre-announce Chime, Alert Tone (AS2220.1) and Evacuate Tone (AS2220.1). Any of these
tones may be activated from a simple contact closure on the rear panel of the amplifier.
Muting
VOX muting is standard on the ACM250. A mic or line signal on channels 1 or 2 will mute chan-
nels 3, 4, 5 and 6. The muting function can be disabled if via an internal link.
Phantom Power
Phantom Power (18V DC) is available from all mic inputs. A rear panel phantom power on/off
switch is also provided.
Protection
Internal current limiting protects the amplifier from both overload and overdrive 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.
