ACM60

60w, 4 Channel
Mi x er Am p lif i er

Description

The ACM60 is a 4 channel, 60 watt mixer amplifi er suitable for table or desk mounting. Alternatively, it can be rack mounted by
means of an optional rack kit. The ampli fier is a self contained compact unit of solid steel constructi on.

Inputs

The ACM60 has four universal input channels with separate level controls. Each c hannel will acc ept balanced or unbalanced
micr ophone, line and auxiliary inputs. The unit has industry standard XLR mic rophone soc kets and dual RCA Phono auxiliary
sockets f or 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 r ecorder output by means of dual RCA
Phono sockets. A balanced 700mV XLR output is also provided to feed up to 6 power amp li fiers.

Speaker Zone Selector

A six position push button speaker zone se lector with overri ding "all c all" is loc ated on the front panel. Each of the si x zone
selectors switch the 100 Volt speaker line output to 6 separate speaker zones. The "all call" selector overrides all 6 zones
regar dless 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 gener ator module. Tones include Bell, Pr e-announce Chime, Alert tone
(AS2220. 1) and E vacuate Tone (AS2220. 1). Any of these tones may be activated f rom a si mple contac t closure c onnected to
the rear panel of the amplifi er. A Pre-announce defeat switc h 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.

Ph anto m P o w e r

Phantom Power (18 volts DC) is available from all mic inputs. A rear panel phantom power on/off switch is also provided.

Protection

Internal curr ent limiting protects the amplifier from both overload and overdrive conditions.

Architectural and Engineering Specifications

The mixer amplif ier shall have four universal input channels, each c omprising of a balanced micr ophone input with XLR fe male
sockets and an auxiliary input using dual Phono RC A sockets. The 100 volt line speaker outputs should be able to be switc hed via
a 6 position selector with "all call." A balanced X LR output to drive additi onal power amplifiers shall also be provided.

The amplif ier master sec tion shall include one master gain c ontr ol, two EQ contr ols, one with 12dB of c ut and boost at 100Hz
and the other with 9dB of cut and boost at 10kHz. Speaker outputs shall be transfor mer isolated at 100 volt, 70 Volt and 8 ohms.
The amplifier must be capable of delivering 60 watts RMS into an 160 ohm inductive load, with less than 0.5% distortion
measured at 1 kHz and with system hum and noise less than -74dB.

The amplifi er shall be an Audio Telex model ACM60, manufactured in Australia.
