3、Quick Start 7 Quick Start 3CONNECT THE AUDIO INPUTS If youre using the CHANNEL 1 INPUT there is a metal tab on the chassis for this purpose. If the DSP-3 is powered by the amplifiers DataPort, the amplifier must be connected to an operational AC power receptacle. Then turn the amplifier “on” using i

4、ts power switch. The blue POWER LED on the DSP-3 will illuminate a few seconds after the amplifiers power switch is activated. If the DSP-3s blue POWER LED does not illuminate, you may have an older QSC DataPort equipped amplifier that requires use of the accessory external power supply (refer to th

5、e Appendix for complete application information). 8 9 Quick Start 5INSTALL THE SOFTWARE 1. Place the QSC Signal Manager CD in your computers 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. Run D:

6、Setup.exe (replace D: with the drive letter designator appropriate for your system) and follow the instructions displayed. 3. When the installation is complete, you will be presented with a screen that prompts you to view the “Readme” file. Please take time to read this- it contains important up-to-

7、date information on the software. 4. After installation, you will have an icon on your computers “desk top” labeled Signal Manager. Use this icon to start the application (double-click on the Signal Manager icon, this will start the program). 5. Using the Menu Bar (see below) at the top of the windo

8、w, choose the “Help” item and read the software help section. The help system includes the contents of this hardware manual for “paperless” reference. 6. IMPORTANT! The DSP-3 is shipped with all of its presets configured to pass full-range audio signals through both channels. THIS MAY NOT BE APPROPR

9、IATE FOR YOUR SETUP! Be sure to configure any necessary crossovers , filters, etc. prior to applying audio signals to the inputs. Damage to equipment may result if these recommendations are not followed. WHAT THE SIGNAL MANAGER APPLICATION LOOKS LIKE This screen-shot is what a typical Signal Manager

11、EW PANE STATUS BAR TITLE BAR MAIN PALETTE CONFIGURATION STATUS PANE 6ESTABLISH COMMUNICATION BETWEEN THE DSP-3 the Options dialog box will open. Click on the DSP tab. In the Serial Port Selection field, click on the “down arrow” next to the port selection data window. A drop down list of COM1 throug

12、h COM4 will appear. Select the COM port number that corresponds to the COM port of your computer that the DSP-3 is connected to. Click OK (at the bottom of the dialog box); the dialog will close. Exit Signal Manager and restart it so that the newly selected COM port will become active. The Communica

13、tion Status pane should now indicate ONLINE if everything was connected and set up properly. 7 MAKE SURE THE AMPLIFIER IS TURNED DOWN AND THAT YOU HAVE SUITABLE SPEAKERS CONNECTED FOR YOUR INTENDED CONFIGURATION For familiarization with the DSP-3 and the Signal Manager software, we recommend that yo

14、u use a pair of full range speakers connected to your amplifier and that the amplifier gain be reduced to the minimum useful setting. This will allow you to configure the DSP-3 almost anyway you desire while providing audio output to verify that the DSP-3 is doing as you intend. Small, high-power ra

15、ted monitor speakers are perfect for the task. Better safe than sorry! Dont turn your amp all the way up; if communica- tions between the computer and DSP-3 fail for any reason, unexpected output transients could damage your speakers 8CREATE A SIMPLE DSP CONFIGURATION 10 ?From the Menu Bar, select C

16、onfiguration, New. If there was a default configuration on the Workspace, you will be prompted to close the “current” configuration first. ?Locate the Inputs and Outputs palette; left-click on the icon labeled IN1. Move your pointer into the upper left area of the Workspace and left-click the mouse

17、again. The IN1 object should now be on your workspace. 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 las

18、t time it was powered down. If you decide to edit an existing configuration, you will need to “unlock” the configuration after opening it. Just select Configuration from the Menu Bar, then select Edit. The palettes that were “grayed out” will now appear in their normal, colored state and you will be

19、 able to edit the configuration. After your editing is complete, select Configuration from the Menu Bar and then Apply to DSP. Thats it for the “Quick Start.” For more information, review this manual and the softwares help file. 11 ?Now select the OUT1 icon from the same palette (left click on the O

20、UT1 icon). Move your pointer into the upper right area of the workspace, in line with the IN1 object you just placed, and left click again. The OUT1 object should appear. ?Select the GAIN icon in the MISC PROCESSORS palette (it looks like a little wedge and is the left-most icon in this palette). Mo

21、ve your pointer to the workspace in between (and in line with) the IN1 and OUT1 objects; click the mouse button again. The GAIN object should appear. ?Go to the DRAWING TOOLS palette and select the DRAW (pencil) icon. Notice that the IN1 object has a small yellow-colored “node” on its right side. Th

22、is is its connection node or the point that “wires” are drawn from. Similarly, note the same yellow-colored nodes on the GAIN and OUT1 objects. Draw a “wire” from the IN1 object to the left side of the GAIN object. Draw another “wire” from the GAIN object (right side) to the OUT1 object. The DRAW to

23、ol works by clicking on one of the nodes that you want to draw a wire between, then, while holding down the mouse button, dragging the wire to the other node. You can change the drawing mode from click-drag-release wiring to click-click wiring in the Tools, Options dialog box; select the Drawing tab

24、 and make any desired drawing “behavior” changes. ?When everything is placed on the workspace and connected with “wires”, go to the Menu Bar and select Configuration, then Apply to DSP (or just click on the “Apply to DSP” icon in the DSP Tools palette). This will send your configuration (and any obj

25、ect parameter settings) from the computer to the DSP-3. The DSP-3s outputs will be muted while the configuration is loaded. For complex configurations, this could take several seconds. ?If you have active audio inputs connected to the DSP-3 and the amplifiers gain is sufficient, you will probably he

26、ar your audio material at this point. If not, double-click on each of the GAIN objects and increase the gain setting as required. Also in the Tools, Options dialog, the DSP tab has settings for input and output sensitivity for the DSP-3; these may require adjustment dependant on your particular set

27、up. ?The Communication Status pane should indicate “ONLINE” and the Configuration Status pane should indicate “ACTIVE”. If you get an error message when applying the configuration to the DSP-3 (i.e. “Failed to connect to DSP-3”) check the cable connection between the DSP-3 and the computers COM port

28、. Ensure that the correct COM port is selected in Signal Managers Tools, Options, DSP settings dialog box. ?Repeat the above procedure, this time using IN2, OUT2 and a GAIN object. This will give you a signal path with gain adjustment for channel 2. Be sure to “Apply to DSP”. This sends your updated

29、 configuration from your computer to the DSP-3. 12 Remote Mounting and External Power required. No DataPort Connection possible, Power Limiting not available. ISA series:The ISA amplifiers have a “V2” DataPort that may be used for audio inputs only. MX series:All PLX series:All RMX seriesAll USA ser

30、ies:All ALL non-QSC amplifiers can be used with the DSP-3. Application Information APPLICATION INFORMATION As design improvements are continuous, the following information is subject to change. Contact QSC for current information. QSCs DSP-3 Module has been designed to attach directly to the DataPor

31、t connector of QSCs CX, DCA, Powerlight, and Powerlight 2 series amplifiers. When attached to CX, DCA, and Powerlight 2 amps manufactured 08/99 and later, the module receives its power through the DataPort from the amplifier. Modules connected to earlier models of those just mentioned and all Powerl

32、ight amplifiers (the “non-2s”) require an external DC supply (available from QSC). TO CLARIFY: CX, DCA, and PL2 amps made prior to August 1999 DO NOT provide adequate power supply voltage to the module, requiring the use of the same type of external DC supply as used with Powerlight amplifiers. The

33、amps in question will have a serial number PRIOR to 0899XXXXX, where the first four digits of the serial number are the MMYY datecode. Again, the modules WILL work with these amps just fine, but will require the use of our external power supply. Remote Mounting, QSC DataPort Cable and External Power

34、 required: Full feature-set. PowerLight series: PL1.0 through PL4.0 (all) PL6.0 and PL9.0 require modified DataPort cable between DSP-3 and amplifier. Full feature set, Direct-mounting, No external power or special interconnect cables required for the following QSC power amplifiers with serial numbe

35、rs of 0899XXXXX and later, where the first four digits of the serial number are the MMYY datecode : CX series: CX302 CX1202V (all) DCA series:DCA1222, DCA1622, DCA2422, DCA3022, DCA342 PL2 series:PL224, PL230, PL236, PL218 PL2A series:All Remote Mounting Required, QSC DataPort Cable required: Full f

CX series:CX204V, CX254, CX404 DCA series:DCA1644, DCA1824 Powerlight 6.0 and 9.0 MUST have pin #9 removed from the amplifier-to- DSP DataPort Cable before use! Sharing Configuration Files Between Different Computers SPECIAL INFORMATION CONCERNING SAVED DSP-3

37、CONFIGURATIONS The computer which is used to create the DSP-3 signal flow configurations, and subsequently save them to disk, should be the same computer used to modify and adjust the DSP-3 settings in the future. Naturally, this might not always be the case. At the least, a copy of the DSP-3 config

38、uration(s) should be saved to floppy disk, so the configuration files can be transferred to whatever computer(s) might be used to adjust or modify the DSP-3 module settings in the future. The reason: The Signal Manager software works in conjunction with the DSP-3 module to create specific signal pro

39、cessing algorithms for filters, delays, limiters, and the like. The algorithms are displayed on the computer screen as ”configuration files”, with graphical representations of each function and parameters. The user creates a signal chain, “wiring” together blocks of functions as needed for each part

40、icular audio channel or channels. When you build a DSP-3 configuration from scratch, or load one from disk, and perform an “Apply to DSP” operation, the information downloaded into the DSP-3 module is NOT the graphical representation of what is displayed on the screen. The downloaded information con

41、sists of the compiled algorithm coefficients of the functions, i.e. “just the math”. If building a new configuration from scratch, when you apply it to the DSP-3 you will also be prompted to save it to disk as a Configuration file. The path for this Configuration file is then associated with the com

42、piled information that is applied to the DSP-3. A previously saved (to disk) configuration file may also be applied to the DSP-3, and that particular file path is associated with the algorithms now loaded in the DSP-3. When you connect a DSP-3 to a computer, the Signal Manager software first attempt

43、s to locate and display the configuration file that has been associated with the algorithm coefficients currently running in the DSP-3, to correlate “what you hear” with “what you see”. This would allow you to further adjust a delay or a filter parameter, for instance. If the correct file is located

44、, based on the associated path name, the graphical configuration is displayed. If the file is not found (the file has been renamed, moved, deleted, or you are not using the same computer on which the DSP-3 was originally configured) the computer will display a message asking if you would like to loa

45、d the Default configuration. Answering YES will load the Default (factory) configuration TO THE SCREEN, but will not apply it to the DSP-3. Answering NO will merely display a blank workspace to the screen with no configuration loaded. At this point, what is displayed is NOT what is currently running

46、 in the DSP-3 memory. IF YOU PERFORM AN “APPLY TO DSP” NOW YOU WILL OVERWRITE WHATEVER IS CURRENTLY RUNNING IN THE DSP-3! This is likely NOT what you want to do. Instead, locate the desired configuration file (from an alternate path or from floppy) using the Configuration-Open menu (Ctrl-O). When th

47、e 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). This will download the currently displayed configuration back into the DSP-3 (overwriting itself), allowing synchronization of what is displayed with what

48、 is running in the DSP-3. At this point, you may adjust parameters or modify settings as usual. QSC engineers are currently developing an improvement to this process, in which the computer would always be capable of displaying the currently running configuration, regardless of the location of the configuration file (or lack of the file). 13 Maintenance, Warranty & QSC Contact Information Cleaning The faceplate and chassis can be cleaned with a soft cloth and nonabrasive, mild cleaning solution.
