SPA100

Introduction:

Congratulations. You have selected one of the finest sound reinforcement amplifiers available,
the Crate Audio SPA100 1/2-Rack Power Amplifier. Our many years of experience in high-perform-
ance audio equipment, combined with our extensive research and development procedures, have
enabled us to produce an amplifier which provides the highest quality and reliability possible.
Like all Crate products, your SPA100 amplifier was designed and manufactured using only the
finest components and materials. Each amplifier design must satisfy our team of highly-trained tech-
nicians and musicians before it is approved. We insist upon high level of quality control to ensure that
each amplifier produced will provide its owner with years of trouble-free, ear-pleasing performance.
Your new SPA100 is a flexible part of any sound system – simple to connect and easy to operate
– if you first know how to incorporate it into your application. Several configurations are covered in
this manual, along with important information regarding impedance ratings and output power. In
order to get the best performance and highest level of quality and reliability from your new amplifier,
please read this user's guide before operating the unit.

Features:

The Crate SPA100 is a ruggedly constructed high quality power amplifier designed to give you
continuous performance with professional results. Two of these amplifiers can be mounted side by side
in a standard 19" rack, requiring only 1-3/4 inches of vertical rack space. The automatic variable-
speed internal cooling system uses the front, side and rear of the amplifier - not the top and bottom -
for its air intake and exhaust, allowing you to stack multiple components closer together in a rack
mount situation.
The SPA100 produces up to 100 watts of power @ 4 ohms, or 75 watts @ 8 ohms. Several "pro-
fessional" features have been built into the SPA100, such as 1/4" phone and XLR input jacks with elec-
tronically balanced Low or High impedance operation. Built-in limiting circuitry constantly monitors
the output of the amplifier for clipping, thus helping prevent the generation of speaker-damaging
square waves. A built-in protection circuit guards the amplifier against damages from overloads, short
circuits, or overheating. In addition, each channel features a Signal LED to assist in hookup and trou-
bleshooting, and a Peak LED to allow you to set the input level for the best signal to noise ratio.
