Operating Manual - DPX-100 Graphic Equalizer - Compressor/Limiter
1. INTRODUCTION
The Ashly DPX-100 combines a 15 band graphic
equalizer and full function peak compressor/limiter in a
single rack space product. Both equalizer and compres-
sor/limiter can be used as stand-alone processors, or can
be automatically chained together with a back panel
switch.
The graphic equalizer section uses professional
quality 25mm faders for maximum resolution and long
life. Ashly graphic equalizers use "Q" enhanced Wein
bridge filters with interleaved summing for constant "Q",
low ripple, and minimum filter interaction.
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-100, 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-100 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
are preselected for 120VAC, 60Hz and should be plugged
into a standard NEMA 5-15 3-wire grounded AC recep-
tacle. Most units distributed outside the US are
preselected and labeled for 240VAC, 50-60Hz and are
shipped with the appropriate power cord.
The DPX-100 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 technician for
servicing. Power consumption is less than 20 watts.

triangle is intended to alert the user to the
presence of important operating and
maintenance instructions in the literature
accompanying the device.
The lightning flash with arrowhead
symbol, within an equilateral triangle, is
intended to alert the user to the presence
of uninsulated "dangerous voltage"
within the product's enclosure that may be
of sufficient magnitude to constitute a risk
of electric shock to persons.
