AUSTRALIAN MONITOR IC30 Series User manual

30W, 3 Channel Mixer Amplifier
IC30
Description
The IC30 is a 3 channel, 30 watt mixer amplifier designed for both AC and 12 volt DC opera-
tion. The amplifier is a self contained compact unit of solid steel construction suitable for table
or desk mounting. An optional rack mount kit is also available.
Inputs
The IC30 has three universal inputs, each with separate level controls. Each channel will accept
balanced or unbalanced microphone or a line/auxiliary input. The unit has industry standard
XLR microphone sockets and a single RCA socket for each channel.
Outputs
The IC30 features 100 volt, 70 volt & 4 ohm isolated transformer outputs. A tape recorder out-
put by means of an RCA is also provided.
Tone Generator
The IC30 will accept the ATC5488, an optional, plug-in four tone generator module. The
ATC5488 connects to a 7 pin receptacle inside the amplifier and provides Bell, Pre-announce
Chime, Alert Tone (AS2220.1) and Evacuate Tone (AS2220.1). Any of these tones can be acti-
vated from a simple contact closure which may be wired to the spare terminals on the rear of
the amplifier.
Muting
The IC30 includes a muting facility where channels 2 and 3 are muted when two terminals on
the rear panel of the amplifier are shorted. Alternatively, an optional plug-in VOX muting card
(TX3010) is available. With the TX3010 installed, signal on input 1 will automatically mute
inputs 2 and 3.
Protection
Internal current limiting protects the amplifier from 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.

ARCHITECTURAL AND ENGINEERING SPECIFICATIONS
The mixer amplifier shall have three universal inputs each comprising of a balanced microphone with
XLR female sockets and auxiliary input using single RCA sockets.
The amplifier master section shall include three channel level controls, two EQ controls, one with 12dB
of cut and boost at 100Hz and the other with 9dB of cut and boost at 10kHz. Speaker outputs shall be
transformer isolated at 100 volt, 70 volt & 4 ohms. The amplifier must be capable of delivering 30 watts
RMS into a 330 inductive ohm load, with less no more than 0.3% distortion measured at 1kHz @ 70 volts
and with system hum and noise at less than -68dB. The amplifier shall be capable of operating on mains
power and 12V DC.
The amplifier shall be an Australian Monitor Installation Series model IC30.
