Peavey Electronics is proud to announce the introduction of a new line of exciting Professional Power Ampli-
fiers. The new CS-G series is the result of years of research & development into a smaller, lighter, compact and more
powerful amplifier. These units operate much more efficiently than contemporary power amp designs, requiring less
current from the mains power plug, producing far less heating. This new technology allows the CS'rM 1800G to reliably
produce more than 1800 W RMS into 4 ohms (Bridge Mode) in a two rack space unit, at extremely low distortion
levels.
These new designs use a new class of operation called "Class BG". This class uses two levels of power supply
"rails," but switches between the rails faster and at lower distortion levels than does a typical Class G design. This unit
then combines higher efficiency and lower distortion, and together with our all new Non-saturating Series Single
Emitter Resistor topology (NSSER), provides awesome performance levels with full power 20 kHz distortion below
U.S. Patent (Pending).
The following is the new CS 1800G specs:
600 W RMS into 4 ohms; 900 W RMS into 2 ohms, per channel
1200 W RMS into 8 ohms; 1800 W RMS into 4 ohms (Bridge mode)
Slew Rate: 40 V/microsecond, stereo mode, each channel
Frequency Response: 20 Hz to 20 kHz, f0.2 dB, at rated power
Total Harmonic Distortion: Less than 0.04%, at rated power
Hum and Noise: 100 dB below rated power, unweighted
The unit is attractively packaged in a rugged, rack-mountable configuration requiring only two rack spaces.
Naturally it has Peavey's patented DDT TM Compression Circuitry, and has a very flexible back panel. The design uses
dual two speed fan cooling to provide all the cooling necessary for the two ohm load conditions.
