[. . . ] Hardware Manual DSP-30 Computer Configurable Digital Signal Processor *TD-000097-00* TD-000097-00 Rev. C 1 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 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 AND SIGNAL MANAGER SOFTWARE WHICH DOES NOT STRICTLY ADHERE TO THE MANUAL'S RECOMMENDATIONS. IMPORTANT SAFETY INFORMATION: PLEASE REVIEW! EXPLANATION OF GRAPHICAL SYMBOLS Federal Communications Commission (FCC) Information NOTE: This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a commercial installation. [. . . ] ACCEPT- after using the BROWSE button to choose a Preset number, press ACCEPT within 30 seconds to activate the selected Preset. NOTE!Pressing the ACCEPT button and holding for at least 3 seconds locks (disables) the BROWSE key to prevent accidental operation. The ACCEPT key must be pressed again and held for at least 3 seconds to "unlock" the BROWSE button so that other presets may be accessed again. AC power receptacleThe DSP-30 uses a detachable IEC standard power cord for connecting to a grounded AC source. To connect power: identify the proper end of the cord, match the orientation of the receptacle on the rear panel and insert firmly into the receptacle. The power supply will accept from 100 to 240 Volts AC, 47 to 63 Hertz. Make sure the power cord used is suitable for the line voltage the unit is connected to. If a different type of IEC power cord is required, contact QSC's Technical Services Department to obtain the correct one. 13 Use: General Use Guidelines and Preset Description IMPORTANT!Please read before operating this Digital Signal Processor with your audio system. General Use Guidelines This is a professional level DSP product that allows the user to produce virtually unlimited signal processor variations and configurations. Because of the infinite configuration possibilities of digital signal processing, it is possible to create configurations that may result in unwanted signals or uncontrollable output. The Signal Manager software has no way of knowing if the DSP configuration you have designed will produce the results you intend. You can create signal loops in a configuration that may oscillate and damage your sound system if applied to the unit. When applying an untested configuration or when designing or experimenting with this unit, it is a very good idea to turn down the amplifier's physical gain controls. That way, you won't damage your speakers or create very loud sounds if you apply a configuration that doesn't do what you thought it would. There is nothing useful to achieve by doing this, you will only create an oscillator that could damage your speakers. If you don't hear a signal when you think you should, DO NOT INCREASE THE GAIN!!!If the signal isn't audible at lower levels, there is something else wrong. Turning up the gain to full exposes you and your system to the possibility that some loose connection somewhere will suddenly send a full-amplitude signal through your sound system. Like all freely configurable signal processing tools, this DSP will do what the configuration your design tells it to do, which may not be what you expect it to do, so use caution. Factory Presets NOTE!You may select configurations from the sample files (*. cfg) within Signal Manager or create your own. 14 Use: Saving Presets Using QSC's Signal Manager software Presets The DSP-30 must be loaded with your desired presets using the Signal Manager program before use. Test all new presets for expected behavior at low power levels to avoid inadvertently damaging speaker systems. You will need to configure the preset memories with signal chains that meet the precise requirements of your sound system using QSC's Signal Manager software. For help creating configurations, refer to the software's on-line Help system for detailed information. Configuring the DSP-30's Presets The DSP configurations created with the Signal Manager software are not usable until they are saved into the DSP. [. . . ] Amplifier Interface--The DSP shall connect to amplifiers using standard 3-pin XLR connections. Provisions for both balanced and unbalanced connection shall be provided. Noise & Tone Generation-- The DSP shall provide pink and white noise generation capability. Level control of noise and tone objects shall be provided Presets-- The DSP shall be capable of storing eight preset configurations. [. . . ]
