CLX-52 Peak Compressor Limiter

Ashly’s CLX-52 Peak Compressor/Limiter is a two-channel universal peak-sen­sitive automatic gain control (AGC) device with exceptional audio perfor­mance, precise controls and rugged durability. The CLX-52 compressor/limiter
uses an “infinite soft-knee” characteristic and timing based on compression
ratio. This, combined with a dual release time, allows program density to
increase as the input signal increases. The result is a peak controller with very
low noise, smooth sound, and excellent stereo tracking without the usual
“constricted” limiter sound.

Front panel controls allow you to set input gain, threshold, ratio, attack time,
release time and output level. Additional front panel features are an in/out
switch for each channel, stereo tie switch and eleven-step LED meters for
gain reduction and input or output level. All audio connections are XLR, ¼”
TRS and euroblock. Each channel has a TRS insert detector patch point which
can be used as a “ducking” input, or in conjunction with an equalizer to pro­duce frequency-sensitive limiting.

A unique feature of Ashly Compressor/ Limiters is the incorporation of a
double release-time constant. When a conventional compressor/limiter is
adjusted for slow release times, transients such as mic “pops” may cause a
severe reduction in gain followed by a slow fadeup, making the action of
the limiter very obvious. With the double time constant, release from gain
reduction after a brief transient is always fast, with a slower release after a
sustained overdrive.

With wide-bandwidth, ultra-low-distortion and a low noise VCA, the CLX-52
is a versatile and highly listenable compressor/limiter. Used in professional
sound reinforcement as a protective device it will prevent audio levels from
overloading systems, or it can be used to reduce the dynamic range of a
signal creating a much louder or fuller sound without increasing the loudness
peaks. The CLX-52 is a versatile and highly listenable compressor/limiter suit­able for use in professional sound reinforcement, recording and broadcast­ing.
