[. . . ] Core2 User Guide Unpacking and Inspection After unpacking the system modules, save all packing materials in case you ever need to ship the units. Thoroughly inspect the modules and packing materials for signs of damage. Report any damage to the carrier at once; report equipment malfunction to your dealer. Communications Notice This equipment generates and uses radio frequency energy and if not installed and used properly, that is, in strict accordance with the manufacturer's instructions, may cause interference to radio and television reception. It has been type tested and found to comply with the limits for a Class B computing device in accordance with the specifications in Subpart B of Part 15 of FCC Rules, which are designated to provide reasonable protection against such interference in a residential installation. [. . . ] (The jumper nearest the edge of the card is for Analog Input 1. ) 3. Replace the Core2 card in the computer, reboot, and launch the Lexicon Control Panel. The corresponding LED under the Type IV logo should be off (indicating that Type IV is inactive on this channel). Punch Tab This page lets you select input Sources for Punch or overdub recording and output monitor Destinations for the sources selected for Punch or overdub recording. The Punch feature lets you perform overdub or punch recording by directly connecting to a Lexicon Studio interface -- no external mixer is required. All computer operating systems have a delay when applications use host processing. The delay will vary depending on the buffer size of the audio hardware. This means that, when playing along with previously recorded tracks, the track you are playing will sound delayed while you are performing. This delay can be overcome by using an external mixer, or by using the Punch feature. 15 15 Using the LexPanel Lexicon The punch feature mixes the input signals directly with the outputs selected for your monitor system (speakers or headphones) to avoid the inherent processing delay from the card to the computer application and back. Unlike monitoring through a tape deck where the input is typically monitored when the transport is in Stop or Record and muted during Play, the input signal is monitored all the time. Configuring the Punch feature 1. Select Enable Punch to turn on monitoring. Select as many input sources as you like, clicking multiple selections with the shift or Ctrl key. Note that only those I/O selections which are currently enabled in the Routing tab will appear as Source and Destination selections. Select the outputs you are using for monitoring. (Often the analog left and right outputs will be connected to an amp and speakers -- digital connection to a mixer is, of course, also possible. ) A mono mix of the selected inputs will be sent to the outputs. If you are using Cubase, select Global Disable from the System Setup dialog to turn off the monitoring through the application so that a delay is not heard from the input signal. The MIX Level Control Mix Level allows you to adjust the volume of the selected Punch sources that are mixed with the VST output assigned to the same outputs (usually "Master"). NOTE: If multiple sources are being summed, the Mix Level may need to be lowered to avoid distortion. In such cases, try an initial setting of 40. 16 16 Lexicon Studio Core2 User Guide Using the LexPanel The Monitor Buttons When using an ASIO application (such as Cubase), the available sources and destinations of Punch are those which are active in Cubase. For example, to route Punch from the LDI-10T A/D 1&2 to LDI10T D/A 1&2, you must activate the corresponding input and output bus in Cubase. Remember that the Lexicon Control Panel must be exited, then re-launched, each time a change is made to the Cubase active streams list. When using the Wave drivers, when the Monitor button is turned on, all channels will be available for selection as Punch sources/destinations. When the Wave audio application in in Play, only those channels which are in use in the audio application are available to Punch routing. This is true even when the audio application has been configured to keep its audio channels open in Stop. (Refer to the specific application's User Guide for details on how to set this up. ) When there is no audio application running (or when the application is in Stop and has not been configured to keep the audio channels open), all channels are available to Punch routing -- provided the Monitor button is turned on. [. . . ] Add memory. · Optimizing Windows for Audio Applications Following are some suggestions that may improve your computer's performance as a dedicated digital audio workstation. Some of these suggestions disable some Windows 95 optimization features and may slow the overall performance of your system when using non-audio applications. Add Memory Adding RAM to your computer will reduce the chance that Windows needs to use Virtual Memory. Defragment Your Hard Drives Defragment your drives on a regular basis. 26 26 Lexicon Studio Core2 User Guide Troubleshooting Run Scan Disk Regularly Scan disk can detect and fix problems before they become fatal. Disconnect Any Mapped Drives That Are No Longer Connected To Your Computer Drives will appear in Explorer with a red "x" under them if the drive is no longer connected to your system. Verify no Drives are Compressed ControlPanel/System/Performance: Make sure it says "Not Installed" after Disk Compression Disable Write-Behind Disk Caching Sets the number of kilobytes that Win95 reads ahead. (Reading ahead makes the audio drive work harder than necessary. ) Graphics Hardware Acceleration In non-AGP computer systems (computers using VGA cards), graphics acceleration settings can force your video card to hog the PCI bus. Crackling and zippering in the audio while opening and moving windows is a warning sign of this. [. . . ]
