A BRIDGE MODE:
The bridge mode on stereo amplifiers is often misunderstood as to the actual operation and usage. In basic terms, when a two- channel amplifier is operated in bridge mode, it is converted into a single channel unit with a power rating equal to the sum of both channel’s power ratings, at a load rating of twice that of the single channel rating. In this case the CS 800s is rated at 600 W RMS per channel into 2 ohms. The bridge mode ratings are 1,200 W RMS into 4 Ohms (minimum load). The bridge mode operation is accomplished by placing the mode switch into the bridge position, connecting the load between the red binding posts of each channel, and then using channel A as the input channel. All channel B input functions are defeated.
Another application for bridge mode operation is to drive sound distribution systems in very large public address applications. In this mode, the CS@ 800X power amplifier can actually drive
DDT’”
Peavey’s patented DDT’” compression system enables the sound man 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 unique circuit that senses signal conditions that might overload the amplifier and reduce the amplifier’s gain when clipping is imminent. The threshold of compression 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 minimizes clipping and distortion, and thus significantly reduces the potential of loudspeaker degradation and damage. The DDT system is automatic,
