ACM60
60w, 4 Channel
Mixer Amplifier

Description

The ACM60 is a 4 channel, 60 watt mixer amplifier suitable for table or desk mounting. Alternatively, it can be rack mounted by
means of an optional rack kit. The amplifier is a self contained compact unit of solid steel construction.
Inputs
The ACM60 has four 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 Phono auxiliary
sockets for each channel. Line input 4 has a lower input sensitivity and is suitable for high level CD players.
Outputs
The ACM60 features 100 volt, 70 volt and 8 ohm isolated transformer outputs, plus a tape recorder output by means of dual RCA
Phono sockets. A balanced 700mV XLR output is also provided to feed up to 6 power amplifiers.
Speaker Zone Selector
A six position push button speaker zone selector with overriding "all call" is located on the front panel. Each of the six zone
selectors switch the 100 Volt speaker line output to 6 separate speaker zones. The "all call" selector overrides all 6 zones
regardless of their on/off condition and places the 100 Volt output to all 6 zones.
Tone Generator
The ACM60 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. A Pre-announce defeat switch is located on the front panel.
Muting
VOX muting is standard on the ACM60. A mic or line signal on channels 1 or 2 will mute channels 3 and 4. The muting function
can be disabled via an internal link.
Phantom Power
Phantom Power (18 volts 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.
