have been provided along the rear of the amplifier for the most secure installation
possible. (Use of these additional supports is strongly recommended.)

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.

PA-600 AMPLIFIER INSTALLATION & MOUNTING
The PA-600 is specifically designed to be rack mounted, either as a permanent
fixture or in a "mobile" rack. As with any large, heavy object, a proper
installation could mean the difference between success and disaster. The front of
the unit is designed to attach to standard rack rails. The four outermost holes
correspond to the screw on standard rack rails (2 rack spaces in height). Use only
10-32 threaded rack screws with large heads (such as a truss heads). The use of
nylon rack mount washers between the screw heads and the faceplate will keep
the faceplate from being scratched. Due to the depth and weight of the PA-600 a
set of rear support holes have been provided. It is highly recommended that the
installer use these holes to support the rear of the amplifier. A support rail, shelf,
or bracket can be attached to the amplifier and then to the installation
enclosure. One thought to keep in mind when considering the related hardware
for this: more is better when it comes to a secure installation - a little extra time
spent on installing a heavy object more than offsets the possible losses that
could be incurred if the object were to be damaged due to inadequate support.
The dimensions below are provided to assist you and/or your installation
engineer in mounting the amplifier securely.
