Chapter 3: Using FWx Overview Using FWx, you can record and archive performances, and you can integrate pre-recorded Pro Tools tracks with live in- puts. By combining these recording and playback features, you can also perform Virtual Soundchecks by playing back tracks you recorded earlier. Signal routing for recording and playback using FWx is done in both Pro Tools and in D-Show. D-Show Signal Routing FWx Outputs (Recording) FWx provides 18 assignable outputs for recording D-Show channels into Pro Tools. For information on assigning D-Show channels for recording, see “D-Show Signal Routing for FWx Recording” on page 11. FWx Inputs (Playback) FWx provides 18 assignable inputs for playback of Pro Tools tracks through your system. For information on assigning Pro Tools tracks for playback in D-Show, see “D-Show Signal Routing for FWx Playback” on page 13. Pro Tools Settings The connection to the FWx card is reflected in the Pro Tools Hardware Setup dialog, and FWx inputs and outputs appear in the Pro Tools I/O Setup dialog. This allows you to assign track inputs and outputs to FWx. D-Show Signal Routing for FWx Recording You can assign any mono or stereo D-Show channel to FWx channels, including channel Direct Outputs, Mains, Auxes, mono or stereo Groups, Matrix outputs, and PQ outputs. Use the Patchbay>Outputs page to route D-Show output busses or Direct Outputs to FWx channels 1-18 for recording. ‹ Using Direct Outputs lets you record discrete channels from the pickoff point you choose. ‹ Using Mains, Aux, Group, Matrix, or PQ outputs lets you record a stereo main mix, one or more stereo submixes, or any combination of these, up to the number of available FWx channels. To route multiple Direct Outputs to Pro Tools for a multitrack recording: 1 In the D-Show Patchbay, click the Directs tab. 2 Click the tab at the left of the grid for the channel or bus type you are routing. 3 Click the Pro Tools tab at the top right of the grid to show the available FWx channels. When using FWx, Pro Tools session bit depth and sample rate are fixed at 24-bit/48 kHz, and cannot be changed. For complete information on configuring your Pro Tools system, see the 003 & 003 Rack Getting Started guide or the Pro Tools Reference Guide. If you configure the Patchbay for playback as well as recording through FWx, be sure to check Pro Tools track outputs for any potential feedback loops before record enabling tracks.

12 4 Click in the channel grid to assign a channel or bus (listed on the left) to FWx channels (listed across the top). 5 Activate and set the level for each Direct Output by clicking its In button and dragging its on-screen encoder in the Direct Out section. 6 Click the Pickoff column in the Patchbay to specify one of the following the pickoff sources for each Direct Output: • top of channel (indicated by a “T”) • pre-fader (indicated by a lowercase “p”) • post-fader (indicated by an uppercase “P”) 7 Configure Pro Tools tracks for multitrack recording. To route the L/R main mix to Pro Tools for a stereo recording: 1 In the D-Show Patchbay, go to the Outputs page. 2 Click the Mains tab to the left of the channel grid. 3 Click the Pro Tools tab at the top right of the grid to show the available FWx channels. 4 Click in the channel grid to route the Main Left and Right outputs to FWx channels 1–2. 5 Configure Pro Tools for stereo recording.

13 D-Show Signal Routing for FWx Playback You can route channels from Pro Tools to D-Show Input Channels and FX Returns to include pre-recorded tracks in your mix. You can use this feature to perform Virtual Sound- checks, use prerecorded click tracks or other material in a per- formance, or mix down the Pro Tools session using D-Show. Use the Patchbay>Inputs page to route FWx channels 1-18 to any available D-Show Input Channels or FX Returns. To route FWx channels to Input Channels and FX Returns: 1 In the D-Show Patchbay, go to the Inputs page. 2 Click the Channels or FX Returns tab to the left of the grid to display the type of channels you want to use. 3 Click the Pro Tools tab at the top right of the grid to show the available FWx channels. 4 Click in the grid to route FWx channels to D-Show Input or FX Return channels. 5 From the ACS or channel Input screens, assign routing for each FWx channel as needed: • Assign to the main L/R bus to include FWx audio in the main mix of a performance. • Assign to a Group, Aux, Matrix, or PQ bus for submixing and monitoring. You can leave FWx channels unassigned and still monitor them in the Solo bus and headphones. . Monitoring FWx Recordings Through D-Show To monitor the recording through D-Show, configure Pro Tools signal routing to play back the main stereo mix through two available Input or FX Return channels. In D-Show, leave the Input or FX Return signal routing unas- signed and use Solo to monitor the recording. To monitor FWx recording from D-Show: 1 In Pro Tools, check the output assignment shown for the currently record-enabled tracks, as follows. • If Pro Tools is only being used for recording, make sure the recording tracks are assigned to an available FWx channel pair. – or – • If simultaneously using Pro Tools to record and play back audio, check output routing to avoid potential feedback loops. Make sure record-enabled tracks do not share the same output assignment as any playback tracks. Assign output of the recording tracks to a discrete pair of FWx channels. 2 In the Patchbay, route the FWx channels to D-Show Input Channels or FX Returns. See “To route FWx channels to Input Channels and FX Returns:” on page 13. 3 Using the ACS or channel Input screens, make sure the FWx record monitoring channels are not assigned to any D-Show bus or output, as follows: • Make sure no Group Bus indicators are lit; press any lit or flashing indicators to unassign. • If you selected multiple channels, the LEDs flash to indi- cate a mixed state of assignments among all the currently selected channels. • Press a flashing indicator LED once to reset all selected to the same setting (usually, assigned). Press again to toggle and unassign all selected channels in unison. Using Synchronization and Time Code with FWx The FWx Option only communicates audio data between D-Show and Pro Tools. If you plan to use Pro Tools as a MIDI Time Code master or slave, a separate MIDI connection for the Pro Tools host com- puter is required. Use a USB MIDI interface with Pro Tools, and connect its ports to the MIDI In/Out ports on the FOH Rack or Mix Rack. For complete information on synchronization and time code features, see the user guide that came with your VENUE system. Patching FWx channels to D-Show FX Returns for playback To avoid potential feedback loops, make sure no channels are simultaneously routing to and receiving from any record-enabled Pro Tools tracks.
