Operating Manual - CLX-52 and CLX-51 Compressor/Limiter

7. TYPICAL APPLICATIONS

The applications of the Ashly CLX-52 and CLX-

51 can be divided into two basic categories, limiting and

compressing. When used as a protective device to pre-

vent audio levels from overloading systems such as tape

recorders, power amplifiers, speakers, or transmitters, it

is generally referred to as a Limiter.

It may also be used to create special effects and

unusual sounds for recording and musical performance

by deliberately reducing the dynamic range of a signal,

creating a much louder or fuller sounding signal without

increasing the loudness peaks, in which case it is referred

to as a compressor.

In either case, the Ashly CLX units offer excep-

tional performance and precise controls for the audio pro-

fessional.

The CLX-52 As A Protective Device

The CLX-52 provides fast and accurate gain con-

trol for the prevention of sound system overload due to

unexpected transients. Sound system distortion is usu-

ally the result of amplifiers running out of power, in which

case nice round waveforms turn into harsh sounding

squared-off waveforms. Looking at it from the perspec-

tive of the speaker diaphragm, this means that, whereas

in normal operation the diaphragm is required to acceler-

ate, slow down, smoothly change direction, and acceler-

ate again, distorted operation requires an instant

acceleration, instant stop, a change of direction, and in-

stant acceleration again.

Since speaker diaphragms are subject to the laws

of physics, they won’t take this kind of punishment for

long. The diaphragm may shatter, or its voice coil may

overheat. In addition to the damaged caused by sustained

overload, the speaker may also be damaged by occasional,

one-shot high level overload, for example, the sound of a

microphone falling face-first onto a hardwood floor. Even

if this type of transient doesn’t destroy a speaker out-

right, it may damage the speaker surround in such a way

as to cause mechanical abrasion and future failure.

Alternatives For Sound System Installations

To install the CLX unit in a sound system using

a passive crossover, insert it between your mixing con-

sole output and the power amplifier input. For systems

using electronic crossovers, there are two ways to use an

Ashly limiter. It may be inserted between the mixer out-

put and the crossover input, in which case it will act on

the entire audio frequency spectrum. Alternately, if the

limiter is inserted between an output of the electric cross-

over and the input of a power amp, it will only affect a

specific band of frequencies.
