DEAR VALUED CUSTOMER.
Earthquake Sound Corporation specializes in manufacturing high end Home and Car
audio products ranging from the smallest driver to the loudest subwoofer system. In its
dedication to excellence, Earthquake has maintained extensive programs in research and
development to provide you with the highest quality audio products.
The PA-600 is a ruggedly constructed high quality professional amplifier. The amplifier
mounts into a standard 19" rack, requiring only two rack spaces (3-1/2 inches, vertically).
Two automatic variable-speed internal cooling fans use the sides, rear and the front of the
amplifier - not the top and bottom - for its air intake and exhaust, allowing you to stack
multiple amplifier closer together in a rack mount situation. Additional rack support holes
have been provided along the rear of the amplifier for the most secure installation
possible. (Use of these additional supports is strongly recommended.)
The PA-600 produce up to 300 watts of power per channel @ 2 ohms, 200 watts per

channel @ 4 ohms stereo mode or 110 watts per channel @ 8 ohms (stereo mode); 560 watts
@ 4 ohms, 380 watts @ 8 ohms (bridged mono mode). Several "professional" features, such
as 1/4" and XLR input jacks with electronically balanced Low or Medium impedance
operation have been built into the amplifier. Limiting circuitry with LED indicators
constantly monitors the output level of each channel and provides protection from clipping,
thus preventing the generation of speaker-damaging square waves. A built-in protection
circuit protects the amplifier from overloads, short circuits, and overheating. In addition,
each channel features a Signal LED to assist in hookup and troubleshooting and a Fault
LED which indicates when the internal protection circuitry is activated.
This owners manual is designed to better acquaint you with the PA-600 pro-
amplifier. It is imperative that you read this manual in its entirety. EARTHQUAKE
technicians and staff are looking forward to answer any questions you might have, please
call (1-800-576-7944).
CAUTION: the PA-600 is capable of generating high sound
pressure levels. You should exercise caution when operating this
amplifier system. Long term exposures to high levels of sound
pressure will cause permanent damage to your hearing. Sound
pressure levels exceeding 85dB can be dangerous with constant
exposure. Set your audio system to a comfortable loudness level.
Earthquake Sound Corporation does not assume liability for
damages resulting from the direct use of the PA-600 , and urges
users to play the PA-600 in moderate levels.
