IMPORTANT SAFETY PRECAUTIONS & EXPLANATION OF SYMBOLS
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 mag-
nitude to constitute a risk of electric shock to humans.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of impor-
tant operating and maintenance (servicing) instructions in this manual.
CAUTION: To reduce the risk of electric shock, do not remove the cover. No user-serviceable parts inside.
Refer servicing to qualified service personnel.
SAFEGUARDS
•Electrical energy can perform many useful functions. This unit has been engineered and manufactured to
assure your personal safety. Improper use can result in potential electrical shock or fire hazards. In order
not to defeat the safeguards, observe the following instructions for its installation, use and servicing.
•Maximum operating ambient temperature is 50° C.
•Never restrict the airflow through the device’s fan or vents.
•When installing equipment into a rack, distribute the units evenly. Otherwise hazardous conditions may
be created by an uneven weight distribution.
•Connect the unit only to a properly rated supply circuit.
•Reliable Earthing (Grounding) of rack-mounted equipment should be maintined.
•To prevent fire or electric shock, do not expose this equipment to rain or moisture.
WARNING!
While QSC has endeavored to develop and produce the most dependable and robust Digital Signal Processor (DSP)
audio product for your use, due to the unlimited and potentially destructive (to the sound system) configurations
that may be applied to the DSP by the user, QSC cannot be held responsible for damages resulting from any devia-
tion or failure by the user to strictly follow the recommendations set forth in the owner’s manual for the integration
of the DSP-4 and Signal Manager software with your sound system.
All risks attendant to integration of user-configurable DSP products with your sound system are assumed by you.
While QSC strives to supply the highest quality technical solutions for Digital Signal Processing, in no event will
QSC or its suppliers be held liable for any damages, consequential, incidental, or otherwise, including any claims
for lost profits and/or savings resulting from any attempted integration of the DSP-4 and Signal Manager software
which does not strictly adhere to the manual’s recommendations.
FCC INTERFERENCE STATEMENT
NOTE: This equipment has been tested and found to comply with the limits for a class B digital device, pur-
suant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harm-
ful interference in a residential installation. This equipment generates, uses, and can radiate radio
frequency energy and if not installed and used in accordance to the instructions, may cause harmful inter-
ference to radio communications. However, there is no guarantee that interference will not occur in a par-
ticular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by switching the equipment off and on, the user is encouraged to try to correct
the interference by one or more of the following measures:
- Reorient or relocate the receiving antenna.
- Increase the separation between the equipment and the receiver.
- Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
- Consult the dealer or an experienced radio or TV technician for help.

Introduction
The DSP-4 is a digital signal processor (DSP ) accessory for
audio power amplifiers. It is designed to reduce the need for
external signal processing while increasing overall system
reliability through distributed intelligence. It is intended pri-
marily for QSC’s CX, DCA, and Powerlight2 series amplifiers
and mounts directly to the rear panel of the 2-RU, 2-channel
models of these amplifiers (pre-August, 1999 date-code of
the CX, DCA and Powerlight2, and all ISA models will
require use of an external power supply). Use of the DSP-4
with Powerlight models requires remote mounting, external
power supply and use of a special interconnect cable
(PL6.0/9.0 only). Refer to the Appendix for application infor-
mation. The DSP-4 can also be used with amplifiers that do
not have a QSC DataPort (older QSC models, non-QSC mod-
els) with a reduced feature set and remote mounting/exter-
nal power.
The signal processing capabilities include Compres-
sors, Limiters, multiple Parametric Filters, High- and Low-
Pass Filters, Shelf Filters, Muting, Attenuation, Multiple
Delays, Polarity Reversal, and Audio Routing. A new feature
of the DSP-4 is amplifier output Power Limiting (QSC
DataPort amplifiers only). Analog-to-digital and digital-to-
analog converters are 24-bit resolution and 48 kHz. sam-
pling rate. Post-processor audio outputs are daisy-chain-
able for connection to additional amplifiers. Input sensitivity
and output level is software selectable. Dynamic range is
greater than 106 dB. Inputs are balanced and the post-DSP
outputs are pseudo balanced.
Physically, the DSP-4 is a small module that “piggybacks”
onto the back panel of the specified QSC amplifiers. It con-
nects directly to the DataPort on the back panel and is
secured with supplied hardware. When used with other
amplifiers, the DSP-4 is mounted remotely on a rack-mount
accessory bracket providing a solid mounting platform.
There are two LED’s; blue to indicate power status and
green to indicate input signal presence.
Connections include an RS-232 port and a DataPort pass-
through connector for use with QSC DataPort products . For
non-DataPort applications, two XLR audio inputs and two
XLR outputs (post-DSP) are provided. There is a power
receptacle for use with amplifiers that do not provide
DataPort power or with non-QSC amplifiers.
Control of the DSP-4 is accomplished with the supplied
QSC Signal Manager software and an RS-232 connection
between the module and PC. The Signal Manager software
provides an easy-to-use graphical user interface where DSP
“objects” are placed onto a palette and connected. This
interface allows for almost infinite configuration possibili-
ties. Once the DSP-4 has been set up as desired and the
configuration saved to the DSP-4, connection to the PC is
no longer required. This feature allows essentially tamper-
proof amplifier DSP set up. Further changes can be imple-
mented in the field by simply connecting a PC and loading
the new setup into the DSP-4.
Operation over an Ethernet network can be accomplished
using QSC’s QSControl platform. Please refer to the soft-
ware documentation (software Help file and Readme.txt
file) for supported feature-set and operation information.
