INTRODUCTION AND CONTENTS AMC+ SERIES INTRODUCTION 3 The Australian Monitor Installation Series AMC+ range of booster amplifiers take the rugged reliability of the famous AMIS range and deliver the same high quality audio reinforcement, in a low cost, 2 rack unit package. The AMC+ booster amplifiers are available in 120 & 250 watt, a dual channel 120 watt and a 4x60 watt version, and offer 100 volt, 70 volt and 4 ohm outputs.
FRONT PANELS 2 1 ALL MODELS HAVE THE SAME FRONT PANEL. 1 ON This LED indicates the unit is powered “on”. 2 POWER This switch switches power on or off the mains. The up position is on. To indicate hazards arising from dangerous voltages. Pour indiquer les risques résultant de tensions dangereuses.
REAR PANEL AMC+460P shown here These terminals are hazardous. External wiring to these terminals requires installation by a professional. 5 4 3 1 INPUT These 3 pin XLR sockets accept the source input for each channel. One input is a male XLR, the other is a female XLR. The male XLR is normally used as a thru output. When wiring from unbalanced sources, pins 1 and 3 should be shorted together.
INSTALLATION MOUNTING MONTAGE Your amplifier is designed for standard 19” rack mounting and occupies 2 EIA rackunits (3.5”). Cet ampli convient pour un montage en rack de 19” et a 2 unités de 3.5”. The mounting centres are: Vertical: 3.0” (76.2mm) Horizontal: 18.2” (461.2mm) to 18.7” (473.8mm) The slots in the mounting flange will accept bolt diameters up to 1/4” (6.35mm).
INSTALLATION DIRECT OUTPUT The output terminal strip accepts wire sizes from 16-22AWG (1.5mm2 – 0.35mm2) or spade lugs. The following table should be used as a guideline for cable sizes. Regulations in your area may require different gauged wire and should be checked before using. OUTPUT 100V 70V 4 OHM DISTANCE WIRE SIZE AMC+120P / AMC+1202P AMC+250P AMC+460P Up to 50m AWG24(0.2mm2) AWG22(0.35mm2) AWG26(0.12mm2) 50m–200m AWG18(0.75mm2) AWG16(1.5mm2) AWG20(0.5mm2) Over 200m AWG16(1.
