User manual AUSTRALIAN MONITOR ACM120 BROCHURE

[. . . ] Description The ACM120 is a 4 channel, 120 watt mixer amplifier suitable for rack or desk mounting. The amplifier is a self contained compact unit of solid steel construction. Inputs 120W, 4 Channel Mixer Amplifier ACM120 The ACM120 has four universal input channels with separate level controls. [. . . ] 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 ACM120. 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 (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.
