- Page 12 INSTALLATION HUM PROBLEMS 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: Electrostatic radiation, Electromagnetic radiation, and Earth loops...
- Page 13 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.
- Page 14 MAINTENANCE Only competent or qualified persons should attempt any service or maintenance of your amplifier. Your new SMA/SBA Series amplifiers 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.
