Installera inte enheten i ett oventilerat stativ, eller direkt ovanför utrustningar som avger värme, t ex effektförstärkare. Se till att omgivningens temperatur vid drift inte överskrider det angivna värdet i produktspecifikationen. Behållaren är försedd med hål och öppningar för ventilering.

To reduce fan noise to an absolute minimum, a thermal sensing and control circuit has been incorporated in the Synthesis S800 that senses increases in temperature within the amplifier and powers a fan at a speed proportional to that temperature increase. When the S800 is "loafing", the fan turns very slowly ­ and quietly. At high listening levels (and the higher operating temperatures this creates within any amplifier), the sensing circuitry causes the fan to turn faster, producing increased cooling. As a result, the fan is never turning faster than necessary, and most of the noise that is generated is masked by the program being listened to. Comprehensive and Isolated Circuit Protection The S800 amplifier employs a sophisticated protective circuit (one for each channel) that senses many possible fault conditions, such as shorted loudspeaker 2. 0 INTRODUCTION AND FEATURES wires or excess power demand, and turns the affected channel(s) and their blue front panel indicators off until the fault condition is removed, at which time normal operation is automatically restored. While protection of this sort is not uncommon in today's well-designed amplifiers, a remarkable feature of the Synthesis S800's protective circuits is that they are optically-coupled to the signal circuit; there is no direct electrical connection between the signal path and the protective circuitry. As a result, there can be no coloration of the music, no interaction between protection and amplification, until certain thresholds are exceeded, at which point the channel(s) turn off completely. 9 3. 0 OPERATION AND CONTROLS OPERATION AND CONTROLS 3. 0 S80 0 3. 1 S800 1. Power Switch Pushing this button is all that is required to turn on the S800 if it is not part of a Synthesis system and the Manual On/Auto On switch (rear panel) is in the Manual On position. If the amplifier is used as part of a JBL Synthesis System, and the Manual On/Auto On switch is in the Auto On position, the amplifier will turn on when the surround processor is activated. The front panel pushbutton power switch is left in the ON (in) position. . Standby Indicator (red) This indicator, immediately above the front panel power switch, will glow red when the amplifier is in the "standby" mode, whether operating as part of a Synthesis system or not.
