status LEDs will be illuminated green. In any event, corrective action should be taken to determine the cause of the thermal shutdown. If the amplifier is not severely overloaded or shorted and air flow is normal in and out of the amplifier, then steps should be taken to provide a cooler environment for all the amplifiers. As a general rule, the cooler electronic equipment is operated, the longer its useful service life.
STUDIO AND FACILITY INSTALLATION
In most low to medium power applications, the power amplifier can be mounted in any configuration. It is desirable that, if at all possible, the power amplifier be located at the top of an equipment stack. This will prevent possible overheating of sensitive equipment by the hot air rising from the power amplifier. As a general rule, most studio requirements will never cause high speed fan operation. However, if they do, this may indicate that you have not taken the necessary steps to provide adequate cooling. Remember, closed up in a cabinet, a DPC Series power amplifier will have severe cooling problems, even at low power levels. Again, inadvertent short circuit or sustained overload usage could also cause temporary thermal shutdown and/or blowing of the fuse. Also, most home wiring and electrical circuits are only 15 amps.
BRIDGE MODE
The bridge mode on stereo amplifiers is often misunderstood as to the actual operation and usage. In basic terms, when a

DDT™
Peavey’s patented DDT (Distortion Detection Technique) compression circuit enables the user to maximize the performance of the amplifier/speaker combination by preventing the power amp from running out of headroom (clipping). This compression system is activated by a very unique circuit that senses signal conditions which might overload the amplifier and activates compression (reduces the amp gain) when clipping is imminent. Threshold of compression, then, is clipping itself, and no specific threshold control is used. This technique effectively utilizes every precious watt available for the power amplifier to reproduce the signal, while at the same time minimizing clipping and distortion and thus significantly reducing the potential of loudspeaker degradation and damage. The DDT system is an automatic
