Operating Manual - CLX-52 and CLX-51 Compressor/Limiter
1. INTRODUCTION
The Ashly CLX-SERIES of Peak Compressor/
Limiters were designed in response to the need for uni-
versal peak-sensitive automatic gain control (AGC) de-
vices with exceptional audio performance and rugged
durability. It took years of research to realize this goal,
with much of that time spent in developing a wide-band-
width, ultra-low-distortion, low noise VCA (voltage con-
trolled amplifier). The resulting products are versatile
and highly listenable compressor/limiters suitable for use
in professional sound reinforcement, recording and broad-
casting.
What’s New?
The CLX-52 replaces the CL-52E with the addi-
tion of a threshold control, an input/output meter select
switch, and XLR connectors. Also, the detector loop is
now on a single TRS patch point, with send on the ring
and return on the tip. Premium components are used
throughout, and computerized automatic assembly equip-
ment verifies that each component's electrical specifica-
tions are within tight tolerances before becoming part of
the circuit assembly. Each finished unit is then tested
twice before leaving the factory, guaranteeing you a
worry-free, professional product for many years. The
CLX-51 is the mono version of the CLX-52.
We ask that you please read this instruction
manual thoroughly before operation so that you may re-
alize all the features and benefits that ASHLY Compres-
sor/Limiters have to offer.
2. UNPACKING
As a part of our system of quality control, every
Ashly product is carefully inspected before leaving the
factory to ensure flawless appearance. After unpacking,
please inspect for any physical damage. Save the ship-
ping carton and all packing materials , as they were care-
fully designed to reduce to minimum the possibility of
transportation damage should the unit again require pack-
ing and shipping. In the event that damage has occurred,
immediately notify your dealer so that a written claim
to cover the damages can be initiated.
The right to any claim against a
public carrier can be forfeited if the car-
rier is not notified promptly and if the
shipping carton and packing materials
are not available for inspection by the
carrier. Save all packing materials
until the claim has been settled.
3. AC POWER REQUIREMENTS
A standard IEC-320 AC inlet is provided on the
rear panel of both CLX models to accept the detachable
power cord shipped with the unit. Units distributed within
the United States are preselected for 120VAC, 60Hz and
should be plugged into a standard NEMA 5-15 3-wire
grounded AC receptacle. Most units distributed outside
the US are preselected and labeled for 240VAC, 50-60Hz
and are shipped with the appropriate power cord.
Both CLX models will perform normally from
95 to 125 volts AC. An internal line fuse is used. In the
event of fuse failure, refer to a qualified service techni-
cian for servicing. Power consumption is 12 watts.
4. MECHANICAL INSTALLATION
The CLX-52 and CLX-51 Compressor/Lim-
iters mount in a standard 19 inch equipment rack. The
mounting screw threads vary with different rack manu-
factures and you should refer to your rack instructions
for proper hardware. An oval head or flat head screw with
a plastic countersink washer is preferred to protect the
finish of the compressor/limiter under the screw.
This unit is housed in a rugged steel case and
will tolerate moderate abuse. However, for road systems
which may be dropped or otherwise subjected to extreme
forces, we recommend some rear support for the chassis
to prevent bending the front panel the front panel when
these forces occur.
For installations where it is desirable to protect
the front panel controls from tampering or accidental
misadjustment, use the Ashly security cover. Installation
is simple and does not require removal of the equipment
from your rack. See your Ashly dealer for details.
