IS SERIES 600W/1200W/1600W STEREO PRO AUDIO AMPLIFIERS INSTALLATION AND OPERATION MANUAL
IMPORTANT SAFETY INFORMATION 1. Save the carton and packing material even if the equipment has arrived in good condition. Should you ever need to ship the unit, use only the original factory packing. 2. Read all documentation before operating your equipment. Retain all documentation for future reference. 3. Follow all instructions printed on unit chassis for proper operation. 4. Do not spill water or other liquids into or on the unit, or operate the unit while standing in liquid. 5.
INTRODUCTION AND CONTENTS The Australian Monitor Installation Series IS600, IS1200 and IS1600 are 2 RU stereo power amplifiers. The IS600 delivers 300 watts per channel @ 4 ohms & the IS1200 delivers 600 watts per channel @ 4 ohms and the IS1600 delivers 800 watts per channel @ 4 ohms. Designed for permanent installations where high quality audioreproduction is required on a small budget, the IS series deliver the sound quality & features contractors require.
FRONT PANEL 1 2 5 3 4 6 3 POWER SWITCH 1 ATTENUATOR There are 2 level controls on all IS models. Each control is labelled for the channel which it controls. 0dB indicates minimum attenuation. 5 ACTIVE INDICATOR This switches AC power to the amplifier. 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.
REAR PANEL 13 14 7 BALANCED XLR INPUT A female 3-pin XLR type connector is provided for each input: Pin 1 = Signal Ground; Pin 2 = Hot (non-inverting or in phase); Pin 3 = Cold (inverting or reverse phase). 8 BALANCED 6.35MM TRS INPUT A female 6.35mm TRS connector is provided for each input. Tip = Hot (non-inverting or in phase); Ring = Cold (inverting or reverse phase); Sleeve = Signal Ground.
INSTALLATION POWER REQUIREMENTS 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. COOLING Each channel of your IS Series amplifier is cooled by an axial fan which draws cool air from the front of the amplifier and expels heated air out the rear of the amplifier.
INSTALLATION BINDING POST OUTPUTS When terminating to the 4 mm binding post (banana jack) output connectors, banana plugs or bare wires can be used. The red terminal is positive and the black terminal is negative (ground). SPEAKER OUTPUTS When using the 4 pole speaker connector for speaker output, use only the mating 4 pole in-line connector. This connector is designed so that both speakers can be fed from a single connector. Two speaker connectors are provided on the amplifier.
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.
OPERATION HUM PROBLEMS SIGNAL GROUND-LIFT SWITCH Most equipment is designed for minimum hum when used under ideal conditions. When connected to other equipment and to a safety earth in an electrically noisy environment, problems may occur. The three "E"s of hum and hum related noise which can plague your audio system are: a) Electrostatic radiation, b) Electromagnetic radiation, and c) Earth loops When proper system hook-up has been made, you may still have some hum or hum related noise.
MAINTENANCE Only competent qualified persons should attempt any service or maintenance of your amplifier. Your IS 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. NOTE: The following instructions are intended for action by qualified personnel only.
