A
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
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)
DDTTM
compression with LED indicators and defeat switch
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
DDTTM
compression system and the very flexible back-panel patching capabilities. The
two-
speed fan cooling system has been improved to automatically provide additional cooling for the
two-ohm load conditions.
