4 Introduction: Overview and Illustrations The DSP-30 and Signal Manager software combine easy-to- use, customizable, two-channel DSP with simple operating- mode selection that requires only two buttons to operate. It can be used with all amplifiers and is housed in a 1-RU , 19-inch rack-mount steel chassis.
5 Introduction: Illustrations and Dimensions Dimensions.
6 Support the Rear for Portable/Mobile Installations If the DSP-30 is to be transported while in a rack, we recommend supporting the rear of the chassis. This will help prevent the unit from being damaged from the increased mechanical stresses of portable and mobile use.
7 Installation: Balanced Audio Connections Connecting Audio Inputs and Outputs All audio connections should be balanced to ensure the best performance. Unbalanced signals may be used if necessary; follow the wiring guidelines below for recommended unbalanced termination.
8 Installation: Unbalanced Audio Connections Connecting Audio Inputs and Outputs Unbalanced inputs can be used if required. If unbal- anced audio sources are used, it is preferable to use an ap- propriate audio transformer (or other unbalanced-to-balanced “converter”) to provide a bal- anced input.
9 Installation: Connecting Audio Inputs and Outputs Audio Connections Once the input and output cables have been properly wired, they can be connected to the receptacles on the rear panel of the DSP-30. INPUTS- Input jacks are “combo” style. They accept either male XLR or 1/4-inch diameter TRS phone plugs.
10 Connecting to the RS-232 Port Connect to the RS-232 port using the 9-pin serial data cable (included in the shipping box). Orient the DB-9 plug correctly, insert the plug fully into the RS-232 port and finger-tighten the retaining screws. The cable length should be 25 feet or less.
11 Installation: System Requirements and Software Installation Software Installation 1. Insert the QSC Signal Manager CD into your drive (typically drive “D:”). If your computer has AUTORUN enabled, the installation will start automatically after several seconds.
12 CH 1 INPUT, CH 2 INPUT - These female XLR-combo jacks are the line-level audio inputs to the unit. TRS or XLR connectors may be used. They are electronically balanced with an input impedance of 8.3k Ohms. If used in an unbalanced configuration, the input impedance is 3.
13 Use: Control, Indicator , and Connector Descriptions RS-232 - This DB-9 female jack is for attaching the serial cable between the unit and the computer. Use this connection for loading your DSP configurations from the computer to the DSP and for “real-time” configuration tuning with Signal Manager software.
14 Use: General Use Guidelines and Preset Description NOTE! The factory setting for all eight presets is wire-through. Signals are passed from input to output without any processing. Y ou may select configurations from the sample files (*.cfg) within Signal Manager or create your own.
15 The DSP-30 must be loaded with your desired presets using the Signal Manager program before use. T est all new presets for expected behavior at low power levels to avoid inadvertently damaging speaker systems. The DSP-30 has eight Preset memories numbered 1 through 8.
16 Use: How to Recall a Preset from the Front Panel TO RECALL A PRESET - 1- Press the BROWSE key until the desired preset number shows in the display . The selection display flashes until Step 2 (below) is completed. 2- Press the ACCEPT key to activate the selected preset in the DSP .
17 TO LOCK THE FRONT P ANEL BUTTONS (Browse and Accept pushbuttons)- 1- Press the Accept button and hold it down for at least three seconds. 2- The “lock” indicator will illuminate. 3- The Browse button is disabled. FRONT P ANEL DISPLA Y - Example shows Preset 7 in “ unlocked ” and “ locked ” state.
18 Use: Contact Closure Feature Contact Closure Feature The contact closure feature is used to trigger gain changes in the DSP . Any configuration that uses one or more switched gain objects (see Signal Manager software Help file ) can take advantage of this feature.
19 Use: RS-232 Pinout Pin Signal Description 1 DCD 2 T D 3 R D 4 DTR 5 GND 6 DSR 7 RTS 8 CTS 9 Contact Closure RS-232 Pinout: The diagram below shows the pin assignments for the female RS-232 connector on the DSP . *Note! Pin 9 is used for contact closure input.
20 TRI-AMPED P A CABINETS WITH SUBWOOFER (refer to illustration at right) Use: Application Example This is highly generalized, but shows the main idea in cre- ating larger systems. In this example, the audio source material is connected to the inputs of all four DSP’ s.
21 Use: Application Example TRI-AMPED P A CABINETS WITH SUBWOOFER: Sample Application Diagram.
22 Specifications Frequency response 20 Hz–20 kHz ±0.4 dB at 1dB below full scale input voltage (all sensitivities) Distortion <0.007% THD+N @ 1dB below full scale output, all sensitivities, 20 Hz– 20 kHz Group Delay 1.00 milliseconds Dynamic range >95dB unweighted, 1.
23 Physical Chassis Type Steel (chassis & covers) Height 1.73 inches Width 18.9 inches (including rack ears) Depth 14.9 inches (including rear ears) 13.
24 Architect ’ s and Engineer ’ s Specification The Digital Signal Processor (DSP) shall provide two independent channels of DSP for signal delivery to all professional power amplifiers. Input and output sensitivity shall be adjustable to accommodate consumer and pro audio signal levels.
25 Maintenance, Warranty & QSC Contact Information Cleaning The faceplate and chassis can be cleaned with a soft cloth and nonabrasive, mild cleaning solution. Products like Simple Green and Windex work well. Do not use powders or scrubbing pads of any type as they are usually abrasive and will permanently damage the finish of your DSP-30.
