Description
The ACM120XL is an 8 channel, 120 watt mixer amplifier suitable for rack or desk mounting.
The amplifier is a self contained compact unit of solid steel construction. This amplifier features
a status LED.
Inputs
The ACM120XL has eight universal input channels with separate level controls. Each channel
will accept balanced or unbalanced microphone, line and auxiliary inputs. The unit has indus-
try standard XLR microphone sockets and dual RCA auxiliary sockets for each channel. Rear
panel dip switches per channel allow the adjustment of line input sensitivity. An insert point is
also featured on the rear panel for those applications where an additional EQ or Feedback
Exterminator may be required.
Outputs
The ACM120XL features 100 volt, 70 volt, 4 & 8 ohm isolated transformer outputs, plus a tape
recorder output by means of dual RCA sockets. A balanced 700mV XLR output is also provided
to feed up to 6 power amplifiers. A vox triggered relay output is also available on the rear panel
for activation of external devices from the vox muting circuit. In most cases this would be used as
a muting bypass relay, which when used with the appropriate external attenuator, such as our
ATC5143 or ATC5143FS, will maintain paging levels irrespective of the attenuator setting.
VCA Control
The master volume level can be controlled remotely. External VCA control would normally be
via a pot connected to a two wire rear panel barrier strip.
Tone Generator
The ACM120XL 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 connected to the rear panel of the amplifier.
Muting
Multiple levels of VOX muting is standard on the ACM120XL. A mic or line signal on channels 1
will mute channels 2 to 8, on channel 2 will mute 3-8 and channel 3, will mute 4-8. The muting
function can be disabled via an internal link. A vox triggered relay output is also available on the
rear panel for activation of external devices from the vox muting circuit. In most cases this would
be used as a muting bypass relay, which when used with the appropriate external attenuator,
such as our ATC5143FS, will maintain paging levels irrespective of the attenuator setting.
Phantom Power
Phantom Power (18 volts DC) is available from all mic inputs. A rear panel phantom power
on/off dip switch is also provided per channel.
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.
