800s POWER AMPLIFIER OWNERS MANUAL
Congratulations on your purchase of the new
CS@
800s
stereo power amplifier. This latest version is the most advanced
ever, using state-of-the-art switching power supply technology to deliver high fidelity and rock solid performance in a two-
rack-space unit that weighs just under 23 pounds. This new design retains the extended performance capability of the old
CS@8OOX,
providing impressive two ohm output power capability, and maintaining the old 4
&
8 ohms ratings with
awesome industry standards for power bandwidth, slew rate and distortion specifications. The new
“S”
design also reflects
a significant improvement in damping factor specifications. Following is the new
CS

The heavy transformer is replaced by an extremely reliable switching power supply that uses proven half-bridge topology
to provide 1,700 watts peak power from a high-efficiency
IGBT
design. The supply has a thermal monitor system with
proportional fold-back which prevents a total shut-down at extreme operating temperatures. The new
CS
800s
retains the
Peavey patented
DDT’”
compression system which virtually eliminates any possibility of clipping. The new back panel
design now includes plug-in modules for both inputs and outputs offering flexible patching features and various connector
choices. Two variable speed DC fans provide tremendous cooling capability upon demand.
