New Extended Specs; Features - Peavey CS 1200X Operating Manual

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 CS@ 1200 power amplifier has been changed to the new, extended-perfor-
mance CS@ 1200X. This upgraded model provides impressive 2-ohm output power capability
while still maintaining the current 4- and g-ohm 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)
Slew Rate: 40 V/microsecond, stereo mode, each channel
Power Bandwidth: 10 Hz to 50 kHz @ 4 ohms, rated power
Total Harmonic Distortion: less than 0.03%, rated power
Hum and Noise: 100 dB below rated power, unweighted
All the current features of the previous units have been retained, including Peavey's patented
speed fan cooling system has been improved to automatically provide additional cooling for the
two-ohm load conditions.
