500A POWER AMPLIFIER
Congratulations on your purchase of the new CS
®
500A stereo power amplifier. This latest version is the most advanced
ever, using state-of-the-art analog power supply technology to deliver high fidelity and rock solid performance in a two-
rack-space unit that’s the little brother of the famous CS
®
800S. This new design retains the extended performance
capability of the old CS
®
400X, providing very impressive two ohm output power capability, and maintaining the old
4 and 8 ohms ratings with awesome industry standards for power bandwidth, slew rate and distortion specifications.
Following are the new CS
®
500A specs:
• Music Power: 275 W RMS @ 4 ohms, 400 W RMS @ 2 ohms (per channel)
• Music Power: 550 W RMS @ 8 ohms, 800 W RMS @ 4 ohms (bridged)
• Continuous Power: 200 W RMS @ 4 ohms, 250 W RMS @ 2 ohms (per channel)
• Continuous Power: 400 W RMS @ 8 ohms, 500 W RMS @ 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
• Damping Factor: Greater than 300 @ 8 ohms, 100 Hz each channel
Two heavy-duty analog transformers are used to provide extremely high power capability and are designed to fit nicely in
a conventional two-rack-space unit. Additionally, the power supply is designed to produce a higher-than-normal no load
voltage value, and has large, over-sized electrolytic capacitors. This combination results in a power supply with a high
Dynamic Headroom value of more than +2 dB. As such this DH value will produce an awesome “music power” output
capability, resulting in a power amp that “sounds” much louder than one would expect from a typical 200 W RMS per
channel unit. The supply has a thermal monitor system that will protect it from extreme overloads and excessive operating
temperatures. The new CS
®
500A retains the Peavey patented DDT
™
compression system which virtually eliminates any
possibility of clipping. The new back panel design 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.
