Operating Manual - DPX-200 Parametric Equalizer - Compressor/Limiter
1. INTRODUCTION
The Ashly DPX-200 combines a four band para-
metric equalizer and full function peak compressor/lim-
iter in a single rack space product. Both equalizer and
compressor/limiter can be used as stand-alone processors,
or can be automatically chained together with a back panel
switch.
Parametric EQ filters offer custom tailoring of
equalization solutions. Where a graphic EQ boosts or
cuts fixed frequencies, a parametric EQ boosts or cuts
tunable frequencies. The DPX-200 parametric equalizer
uses two tunable shelving filters along with two fully ad-
justable, 20Hz-20KHz parametric filters, resulting in very
precise control of frequency response.
The Ashly compressor limiter circuit was de-
signed in response to the need for universal peak-sensi-
tive automatic gain control (AGC) devices with
exceptional audio performance and rugged durability.
The result is a wide-bandwidth, ultra-low-distortion, low
noise VCA (voltage controlled amplifier) which is versa-
tile and highly listenable.
Premium components are used throughout the
DPX-200, 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.
Please read this instruction manual thoroughly
before operation so that you may realize all the features
and benefits the Ashly DPX-200 has 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 carrier is not notified promptly and
if the shipping carton and packing materials are not avail-
able for inspection by the carrier. Save all packing mate-
rials until the claim has been settled.
3. AC POWER REQUIREMENTS
A standard IEC-320 AC inlet is provided on the
rear panel to accept the detachable power cord shipped
with the unit. Units distributed within the United States
