[. . . ] b) If you place your crossover in DSP # 2, the filters can only be placed in DSP 2 or DSP 3. c) If you place your crossover in DSP #3, the filters can only reside in DSP 3. This feature can prove beneficial when you are trying to "shuffle" around DSP resources. The same rule applies regarding Y memory placement as mentioned in Editing Filter Tool Parameters. 17 After you have selected the desired number of filters, click the "OK" button. You will then see a series dialog windows relating to each crossover output. You will see one of these dialog windows for every output of the chosen crossover, if additional filters for that output have been selected. (If no additional filters have been selected for any or all of the Crossover outputs, you will be prompted for Crossover output designation when you wire the device. ) This allows you to rename that particular filter device. After you click "OK", you will then be prompted to place the device where you want it on the screen. Figure 17. When you have finished, your crossover device (in this case a 4-way) should look something like this (Your wire lines may look different. You can select different line styles later): Figure 18. 18 3. Editing Delay Parameters Delay times are generated in the ISP-100 by using system memory and NOT DSP cycles. This is a great advantage over some other products by not wasting DSP resources for this function. Therefore, when you change delay parameters, you will not see any impact on DSP resources. Each DSP chip is capable of a maximum of 2. 7 seconds (2700 Ms), for a total system allocation of 8. 1 seconds (8100 Ms). The QuickBUILD software will monitor your delay usage per chip and not allow you to exceed this limit. For example, if you place a 2500 Ms delay in a given chip, the next delay device you place (in that same chip) will only be allowed up to 200 Ms. If you did not assign a delay time when you placed your Delay device, or you want to change that time, right mouse click and select "Edit". You will see the following dialog window: Figure 19. You can either type in the delay value you want in the Max Delay Time window, or you can use the "Up and Down" arrows. The arrows will change the delay time in 50 Ms increments. In order to explain the Delay Bias, you need to understand some basic characteristics of analog and digital inputs and outputs. When you are bringing in an analog audio signal to a digital processor, or sending out a digital signal to the analog world, that signal must go through an Analog to Digital (A to D) or Digital to Analog (D to A) converter. [. . . ] Otherwise files will default to be opened from the QuickBUILD Maptool directory. 31 SECTION 5 ­ DOCUMENTING YOUR SYSTEM ___________________________________ Defining System Description When you have completed your system design, you will want to create a "system description". When you create a new project in the VUE-IT software, you will be shown a menu of QuickMAPS to choose from. Figure 40. The "Name" represents the file name you gave your design when you saved it. The "I/O Configuration" is automatically generated from the design itself, and "Create" and "Modify" are automatically time and date stamped. [. . . ]
