QSC® is a registered trademark of QSC Audio Products, Inc. , Costa Mesa, CA "QSC" and the QSC logo are registered with the U. S. Patent and Trademark Office 3 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 DEVIATION OR FAILURE BY THE USER TO STRICTLY FOLLOW THE RECOMMENDATIONS SET FORTH IN THE OWNER'S MANUAL FOR THE INTEGRATION OF THE DSP-3 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. [. . . ] The DSP-3 samples the IMON and VMON (current and voltage monitoring from the amplifier) lines of QSC amplifiers (via the DataPort) in order to perform dynamics (limiter, compressor, etc. ) processing. The four inputs (IMON and VMON for both channels) are continuously sampled by a four channel ADC. When used with non-QSC amplifiers or QSC amplifiers that have no DataPort, the power limiter DSP "object" is not available as this function relies upon amplifier current and voltage feedback. The DSP-3 will also not be able to monitor the protect or power status of the amplifier as these features require amplifier data via a DataPort connection. Contact Closure When using the external power source, we recommend that the DSP-3 be powered-up before the amplifier in order to insure trouble-free start-up. This will also avoid the possibility of "thumps & bumps" should the DSP-3 be powered up after the amplifier. to non-QSC amplifiers (or any amplifier that does not have a DataPort). External power is provided by the accessory power supply ("wall wart") via a coaxial power cord jack on the back of the DSP-3. 17 Section 2: Installation- Unpacking and Mounting 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. If service is required and the original packing material is not available, insure that the DSP-3 is adequately protected for shipment (strong box of appropriate size , sufficient packing material). WHAT IS INCLUDED IN THE CARTON: Item 123456Description DSP-3 Digital Signal Processor 3-pin terminal block connector plug #4-40 machine screw, 1. 125" long #8-32 machine screw, 0. 312" long Hardware Manual (this document) Signal Manager Software CD disk Quantity 1 4 2 1 1 1 DIRECT MOUNTING THE DSP-3 TO 2-CHANNEL, 2 RU QSC DATAPORT EQUIPPED AMPLIFIERS (CX, DCA, Powerlight2) The DSP-3 mounts directly to the rear of 2-channel, 2-RU, DataPort equipped QSC amplifiers. 1- Configure the amplifiers DIP switches (QSC amplifiers where the DSP-3 covers the configuration switches) as follows: ·All filters off ·Clip limiter off ·Mode set as required 2- Align the DataPort plug on the back of the DSP-3 with the DataPort jack on the back of the amplifier and gently push the DSP-3 to seat the connector. 3- Install the two #4-40 screws to secure the left side of the DSP-3 to the amplifier. These two long screws pass through the DSP-3 and thread into the inserts on the DataPort (HD15) jack. The DSP-3's "backside" DataPort connector can be easily damaged if the DSP-3 is twisted and there are no supporting screws to properly secure it to the chassis. 4- Install the #8-32 screw (0. 312 inch long) to secure the right side of the DSP-3 to the amplifier (see below). 18 Section 2: Installation- Remote mounting (4-ch. , Powerlight & non QSC amp's) 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. Keep in mind that all applications that use amplifiers that do not have a DataPort ( i. e. nonQSC amplifiers) some of the dynamic processing capabilities of the DSP-3 will not be available. Accessory Remote Mounting Bracket- This accessory is a 19", 2-RU panel with mounting facilities for up to four DSP-3 modules. It is intended to be mounted to the rear-support rails of an equipment rack. The bracket kit comes with one large bracket ( the 19", 2-RU size) and four smaller right-angle brackets that are used for securely mounting up to four DSP-3's in a 2-RU space. The right-angle bracket is attached as shown, below. 2- Attach the DSP-3 & right-angle bracket to the main 19" bracket as shown, below. 3- Mount the main bracket assembly in your equipment rack between the rear support rails. 4- Attach the inputs, outputs, DataPorts, RS-232 and external power as required. 19 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. [. . . ] At this point, what is displayed is NOT what is currently running in the DSP-3 memory. IF YOU PERFORM AN "APPLY TO DSP" NOW YOU WILL OVERWRITE WHATEVER IS CURRENTLY RUNNING IN THE DSP-3!Instead, locate the desired configuration file (from an alternate path or from floppy) using the Configuration->Open menu (Ctrl-O). When the proper configuration file is displayed on the screen, go to the Configuration->Edit menu (Ctrl-E), followed by an Apply to DSP command (Ctrl-D). [. . . ]
