Peavey CS 1200X - Manual (Page 3)

WARNING!
For optimum performance and reliability DO NOT PRESENT THE AMPLIFIER WITH A SPEAKER LOAD OF LESS THAN 2 OHMS, OR A
COMBINATION OF SPEAKERS THAT TOGETHER ARE LESS THAN 2 OHMS!
Using one speaker, it must be rated at 2 ohms minimum.
Using two speakers, they must be rated each at 4 ohms minimum.
Using three speakers, they must be rated each at 8 ohms minimum.
The world-famous 1200 power amplifier has been changed to the new, extended-perfor-
mance This upgraded model provides impressive output power capability
while still maintaining the current and ratings, and meets rigid industry standards for
power bandwidth, slew rate, and distortion specifications.
The new extended specs are:
630 W RMS into 4 ohms 900 W RMS into 2 ohms (per channel)
1260 W RMS into 8 ohms 1800 W RMS into 4 ohms (bridged)
compression with LED indicators and defeat switch
Slew Rate: 40 V/microsecond, stereo mode, each channel
Power Bandwidth: 10 Hz to 50
4 ohms, rated power
Total Harmonic Distortion: less than rated power
Hum and Noise: 100 below rated power, unweighted
All the current features of the previous units have been retained, including Peavey’s patented
compression system and the very flexible back-panel patching capabilities. The
speed fan cooling system has been improved to automatically provide additional cooling for the
two-ohm load conditions.
