EXPLANATION OF GRAPHICAL SYMBOLS The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsu- lated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a risk of electric shock to humans.
Section 1: Introduction- Overview 5 The DSP-3 is a digital signal processor ( or DSP ) accessory for audio power amplifiers designed to reduce the need for exter- nal signal processing while increasing overall system reliability through distributed intelligence.
IMPORTANT! Pleas read before operating the DSP-3 with your audio system. The DSP-3 is a professional level DSP product that allows the user to produce virtually unlimited signal processor varia- tions and configurations.
This quick start section is for those users who want to get up and running with the DSP-3 and Signal Manager software as quickly as possible. It is in no way a substitute for reviewing the contents of the entire hardware manual.
Section 1: Introduction- Quick Start 3 CONNECT THE AUDIO INPUTS If your using....... the CHANNEL 1 INPUT & CHANNEL 2 INPUT connectors the DataPort input (QSC CM16a or related products) Then you need to.
9 Section 1: Introduction- Quick Start 5 INST ALL THE SOFTW ARE 1. Place the QSC Signal Manager CD in your computer’s CD drive (typically the D: drive). The installation program should run automatically after several seconds; if it does not, then proceed with step 2: 2.
6 EST ABLISH COMMUNICA TION BETWEEN THE DSP-3 & THE COMPUTER Section 1: Introduction- Quick Start At this point, you should have everything “up and running”. In the Signal Manager application, check the COMMUNICATION STATUS PANE (lower right corner of the Signal Manager window, see above).
Section 1: Introduction- Quick Start The last applied configuration that is “running” in the DSP-3 when it is turned off becomes the active configuration again once the power is turned back on to the DSP-3. This ensures that the system “comes up” just as it was left last time it was powered down.
Section 1: Introduction- Basic Connector & Indicator Descriptions 12 RS-232 - This DB-9 fe- male jack is where the serial cable between the DSP-3 and the computer is plugged in. FRONT P ANEL CH 1 INPUT, CH 2 INPUT - These terminal-block jacks (receptacles) are where you connect the line-level audio inputs to the DSP-3.
Section 1: Introduction- Basic Connector & Indicator Descriptions 13 REAR P ANEL OVERALL DATAPORT (unlabeled)- This is the “output” DataPort. If the DSP-3 is directly mounted on a 2-RU QSC DataPort equipped amplifier, this connector plugs into the amplifier’s DataPort connector.

Section 1: Introduction- T echnical Overview 17 Audio Input Path There are two audio channels each with two input connectors, a balanced 3-pin ‘euro’ terminal block jack and an electronically balanced DataPort input. The inputs are protected with a filter that prevents radio frequency interference.
Section 2: Installation- Unpacking and Mounting 18 UNPACKING There are no special unpacking precautions for the DSP-3. However, it is recommended that you keep the original packing material for reuse in the rare event that service be required for your DSP-3.
Section 2: Installation- Remote mounting (4-ch., Powerlight & non QSC amp ’ s) 19 REMOTE MOUNTING THE DSP-3 : 4-Channel CX and DCA , Powerlight series, and all non-QSC amplifiers Use of the DSP-3 with the 4-channel CX and DCA and all Powerlight amplifiers requires the remote mounting of the DSP-3.
20 Section 2: Installation- Connections CONNECTING AUDIO INPUTS AND OUTPUTS: The audio inputs and outputs of the DSP-3 use 3-pin “Phoenix”-type (Euro-style) terminal block connectors.
21 Section 2: Installation- Connections DATAPORT Connection- This section applies to those users interfacing with the QSC DataPort products. If using the DataPort for your audio inputs, DO NOT use the terminal block inputs.
Section 2: Installation- Connections 22 DAISY-CHAINING THE DSP-3 OUTPUTS TO ADDITIONAL AMPLIFIERS The DSP-3 provides audio output jacks for each channel. These outputs may be used for daisy-chaining the post-DSP signal to other amplifiers or for monitoring purposes.
Section 2: Installation- Application Examples DSP-3 Directly Mounted to QSC Amplifier. Audio Inputs via Terminal Block Inputs DSP-3 Directly Mounted to QSC Amplifier. Networked OR Local Control. Audio Inputs via DataPort. The following examples show basic hook up information that assumes a two-channel, full range audio signal driving the load.
Section 2: Installation- Application Examples DSP-3 Remotely Mounted used with QSC DataPort Amplifier. Audio Input via Terminal Block Inputs DSP-3 Directly Mounted to QSC Amplifiers, Networked Control via QSCcontrol Products 24 NOTE: External accessory power supply may be required on older models, see Appendix for application information.
DSP-3 Remotely Mounted connected to any Non-DataPort Amplifier. Audio Input via Terminal Block Inputs Section 2: Installation- Application Examples 25.
26 Section 3: Signal Manager Software- Software Installation Software Installation- 1. Insert the CD labeled QSC DSP-3 Signal Manager into your CD drive (typically drive “D:”). If your computer has AUTORUN enabled, the installation utility will start automatically.
