INTRODUCTION AND CONTENTS AMNG SERIES INTRODUCTION 3 Congratulations on choosing Australian Monitor for your professional amplification requirements. FEATURES 4 The AMNG Series Audio Power Amplifiers embrace all aspects of a professional tool exhibiting quality, reliability and longevity. The visual appearance, mechanical, electrical and sonic parameters have been optimized using our dedicated manufacturing process.

CONTROLS, CONNECTORS & INDICATORS 8 6 5 1 7 3 FRONT PANEL The AMNG Series differ only slightly across all models and all share the same features on their front panels. The functions of the controls and indicators are as follows: 1 Power Switch Press the switch to up for power on and down for power off. At start-up (turn-on), the input to the amplifier is muted for approximately two seconds.
CONTROLS, CONNECTORS & INDICATORS 11 9 16 10 17 REAR PANEL 9 Balanced Input A female 3-pin combined XLR/TRS type connector is provided on each input: Pin 1/Sleeve = Signal Ground; Pin 2/Tip = Hot (non-inverting or in phase); Pin 3/Ring = Cold (inverting or reverse phase). 10 Signal Strapping A male 3-pin XLR type connector is provided and wired in parallel with the female input XLR for strapping / looping signal between amplifiers.
INSTALLATION Power Requirements When wiring for an unbalanced source: Power consumption for your model of the AMNG Series amplifier is indicated on the rear panel for maximum output. Pin 1/Sleeve = GROUND/SHIELD Ensure that your mains voltage is the same as the rear panel mains voltage marker (+/- 10%). Mounting Your amplifier is designed for standard 19” (482mm) rack mounting and occupies 2 EIA rack units 3.5” (88mm). The mounting centres are: Vertical: 3.0” (76.2mm) Horizontal: 18.2” (461.
INSTALLATION Speaker Connector Wiring Diagram Hum Problems continued This is by far the most common cause of hum, and it occurs when source equipment and the amplifier are plugged into different points along the safety earth where the safety earth wiring has a current flowing through it. The current flowing through the wire produces a voltage drop due to the wire’s resistance.
OPERATION IMPORTANT: All signal source equipment should be adequately earthed. This not only ensures your safety but everybody else’s as well. Faults can and do occur in mains connected equipment where the chassis can become “live” if it is not properly earthed. In these instances, the fault in a “floating” (ungrounded) piece of equipment will look for the shortest path to ground, which could possibly be your amplifier’s input.
MAINTENANCE Only competent or qualified persons should attempt any service or maintenance of your amplifier. Your AMNG Series amplifier will need minimal maintenance. No internal adjustments need to be made to the unit to maintain optimum performance. To provide years of unhindered operation we suggest a maintenance inspection be carried out on a regular basis, say every 12 months or so. Fans Over time, dust may build up on the leading edge of the fan blades and reduce their cooling efficiency.
