INTRODUCTION AND CONTENTS AMC+ SERIES INTRODUCTION 3 The Australian Monitor AMC+ series of amplifiers takes the heritage and reliability of our famous AMIS series amplifiers and integrates these features into low cost amplifiers for applications where reliability is everything, but the more elaborate features of our AMIS series are not required.
FRONT PANEL 1 2 3 4 5 6 1 CH 1–4 These control the levels for each channel input. 2 Bass There is 12dB of cut and boost at 100Hz. 3 Treble There is 9dB of cut and boost at 10kHz. 4 Master This controls the overall mixed output level. 5 On This LED indicates the unit is powered “on”. 6 Power This switch switches power on or off the mains. The up position is on.
REAR PANEL 5 4 7 6 1 CH 1–4 Each channel input section has two inputs: XLR input – This is a balanced microphone input. It has an input sensitivity of 1mV. RCA input – This is an unbalanced line level input. It has an input sensitivity of 150mV. The two RCA sockets are summed to mono internally.
INSTALLATION Mounting When rack mounting, it is advisable to allow 1 rack space above and below the amplifier. When multiple amplifiers are mounted in a rack, exhaust fans should be used on the rack. Airflow for cooling the AMC30, AMC60 and AMC120 is by convection from bottom to top. Airflow for cooling the AMC250 is by fan from front to side. Output Distance Wire Size + 100V 70V 4 ohm Direct Output The output terminal strip accepts wire sizes from 16-22AWG (1.5mm2 – 0.35mm2) or spade lugs.

FUNCTIONAL NOTES AND INTERNAL ADJUSTMENTS Priority Channel 1 will mute channels 2, 3 and 4. This will only occur when signal appears on channel 1, irrespective of the channel volume control. Priority can be disabled. (See below). The release time is approx. 3 secs and is NOT adjustable. The mute depth is approx. 40dB and is not adjustable.
