INTRODUCTION AND CONTENTS XA SERIES INTRODUCTION 3 Congratulations on choosing Australian Monitor for your professional amplification requirements. FEATURES 4 The design of our XA Series Audio Power Amplifiers embraces all the aspects of a well designed amplifier. The visual design, mechanical, electrical and sonic parameters, along with our dedicated manufacturing process, have all been optimized to provide a professional tool that exhibits quality, reliability and longevity.
FEATURES & PROTECTION FEATURES FEATURES Custom designed, 2RU heavy duty steel chassis Signal ground lift switch Front carry handles Built in limiter circuit Symmetrical layout – even-weight distribution Stereo, bridged or parallel operation Class G operation Binding post and 4 pole speaker output connection High efficiency switch mode power supply VU meter Efficient front to back cooling Output clip indication Variable speed axial fans Multi-role output fault indication Balanced inputs and bu
CONTROLS, CONNECTORS & INDICATORS 8 6 5 1 7 3 FRONT PANEL The XA 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 XA 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” rack mounting and occupies 2 EIA rack units (3.5”). The mounting centres are: Vertical: 3.0” (76.2mm) Horizontal: 18.2” (461.2mm) to 18.7” (473.8mm).
INSTALLATION Speaker Connector Wiring Diagram Ensure the mains power for the audio system is “quiet” i.e. without equipment on it such as air-conditioning, refrigeration or lighting which may generate noise in the earth circuit. Ensure all equipment within the system shares a common ground/ safety earth point. This will reduce the possibility of circulating earth currents, as the equipment will be referenced to the same ground potential.
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 XA 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.
