C O N T R O L S , C O N N E C T O R S & I N D I C AT O R S 6 1 Front Panel 1 2 Power Switch Thermal Indicator In the advent of a thermal overload, this LED will turn red, indicating that the internal operating temperature of one or both amplifier channels has exceeded a safe level of operation and the channels will be automatically muted. The fans will continue to run and once the effected channel/s have cooled, they will un-mute and return to normal operation.

I N S TA L L AT I O N Power Requirements Power consumption for your model of the Synergy-2 Series amplifier is indicated on the rear panel for maximum output. 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).
I N S TA L L AT I O N 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. When proper system hook-up has been made, you may still have some hum or hum related noise. This may be due to any of the previously mentioned gremlins.
O P E R AT I O N 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 Synergy-2 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.
