Chapter 3: Using HDx

OverviewEach HDx card allows up to 64 channels of audio to be re-corded into Pro Tools. You can also playback your recorded tracks through your VENUE system so you can, for example, perform a Virtual Soundcheck.

Two HDx cards can be installed into an FOH Rack, allowing up to 128 record or playback channels. You can also operate the cards in a redundant output configuration, allowing you to re-cord to two discrete Pro Tools systems.

Signal routing for recording or playback is configured in both VENUE and Pro Tools.

VENUE System Settings

Recording

Send direct digital splits of Mix Rack or Stage Rack inputs 1–48 (or 49–96 if using a second Stage Rack and a second HDx card) to Pro Tools. See “Enabling Digital Splits” on page 17 and “Recording Digital Splits” on page 21.

Using assignable outputs, record the Main L/R mix using Di-rect Outs, or record submixes (or stems) using VENUE system bus outputs. See “Recording the Main L/R Mix” on page 19 and “Recording Submixes” on page 20.

Record all 48 Stage inputs, plus any assignable outputs, to two independent, 64-channel Pro Tools|HD systems (or to Pro Tools|HD system and an external MADI device if you have an HDx card and a VENUE MADI card installed) in a redun-dant output configuration. See “Enabling Redundant Out-puts” on page 19.

Playback

Virtually Soundcheck the band using Virtual Soundcheck mode. Pre-recorded Pro Tools tracks are the main source of au-dio for VENUE. Stage inputs on your VENUE system are re-placed with inputs from Pro Tools. You can then make changes in Virtual Soundcheck mode, including creating and modifying Snapshots. These changes carry over when switch-ing back to Stage mode. See “Enabling Virtual Soundcheck Mode” on page 17.

Replace your Stage inputs with audio from Pro Tools using Input mode. In this mode, audio from Pro Tools is the main audio source for your VENUE system. Stage inputs on your VENUE system are replaced with inputs from Pro Tools. Un-like Virtual Soundcheck mode, input channel gain, HPF, and other PRE parameters are ignored (sources from Pro Tools are reset to default, i.e, taken “direct” into VENUE). See “Enabling Input Mode” on page 18.

Playback Pro Tools tracks using assignable inputs. Mix pre-recorded tracks from Pro Tools in with your live mix, monitor your live recording, or mix-down tracks using your VENUE system. See “Playing Back and Monitoring Pro Tools Tracks” on page 21.

Signal Routing for Recording Direct Digital Splits in Stage ModeIn Stage Mode, each HDx card provides a direct digital split of all 48 Stage input channels outputs. The input signal is split im-mediately after the input stage, and these input signals are sent directly to Pro Tools. The direct digital split channels do not ap-pear separately in the Patchbay.

In this mode, 16 assignable outputs for recording and 16 assignable inputs for playback are freely available.

Mix Rack inputs are referred to as “Stage” inputs, while Stage Rack inputs are referred to as “Stage 1” and “Stage 2” inputs.

Enabling Digital SplitsTo send digital splits of your VENUE system Stage input chan-nels, you must enable your VENUE system’s Stage inputs.

To enable digital splits of VENUE Stage input channels:

1 Do one of the following to put your system into Config Mode:

• Press the Console Config switch on the console.

– or –

• Double-click the Mode box in the bottom-right corner of the screen.

2 Go to the Options page and click the System tab to access the System Configuration page.

3 Click Edit.

4 For Stage 1 inputs, in the Inputs section of the System Con-figuration page, beneath Inputs 1–48, select Stage 1 (or Stage for Mix Rack).

5 For systems with a second Stage Rack, do the following:

• Select Enable Stage 2.

• Select Enable HDX 2.

• In the Inputs section of the System Configuration page, beneath Inputs 49–96, select Stage 2.

6 Click Apply. The system restarts with all selected Stage inputs active. Any audio present on VENUE system Stage input chan-nels is sent to all HDx card ports.

Selecting Stage 1 inputs

Enabling Stage 2

Selecting Stage 2

Enabling Virtual Soundcheck ModeIn Virtual Soundcheck mode, audio from Pro Tools replaces the corresponding Stage inputs one-for-one, and appear in place of those Stage Inputs in the VENUE Patchbay. The digi-tal portion of the gain for each channel is preserved and ap-plied to the incoming signal from Pro Tools. This results in the same apparent levels for Pro Tools inputs and Stage inputs. All changes to your live mix (such as channel assignments, and input and output processing) carry over when you switch to Virtual Soundcheck mode.

When exiting Virtual Soundcheck mode and returning to Stage mode, you can choose whether or not to apply input channel gain changes to Stage input channels made while in Virtual Soundcheck mode.

To enable Virtual Soundcheck mode:

1 Put your system into Config mode.


3 Click Edit.

4 For the first HDx card, in the Inputs section of the System Configuration page, beneath Inputs 1–48 select HDx1, then se-lect Virtual Soundcheck from the Input format pop-up menu.

5 For systems with a second HDx card, do the following:

• Select Enable Stage 2.

• Select Enable HDx2.

• In the Inputs section of the System Configuration page, beneath Inputs 49–96, select HDx2, then select Virtual Soundcheck from the Input format pop-up menu.

6 Click Apply.

In VENUE software 2.8.1 and lower, the mode called HDx Input was the only mode available for replacing Stage inputs with Pro Tools audio inputs. It provided all Virtual Sound-check features. Beginning in VENUE software 2.9, these fea-tures are provided in two separate operating modes.

Enabling Virtual Soundcheck HDx 1 inputs

Selecting Virtual Soundcheck for HDx2 inputs


The Stage tabs in the Patchbay are replaced by HDx tabs, and all Stage routing is preserved. Audio from Pro Tools is sent to connected HDx card ports. A history Show file of the previous configuration is also created and stored in Filing > History.

Exiting Virtual Soundcheck Mode

To exit Virtual Soundcheck mode and return to Stage mode:



3 In the Inputs section of the System Configuration page, be-neath Inputs 1–48, select Stage 1 (or Stage for Mix Rack).

4 For systems with a second Stage Rack, In the Inputs section of the System Configuration page, beneath Inputs 49–96, se-lect Stage 2.

5 When the Apply/Discard dialog appears, click either of the following as desired:

Apply Any gain changes made in Virtual Soundcheck mode are added to the total Stage input gain on each channel.

Discard Any gain changes made in Virtual Soundcheck mode are lost and the Stage input gain is returned to its previous value on each channel.

For example, if you set the Stage Rack gain for a channel to +30 dB, then switch to MADI Virtual Soundcheck inputs, a digital gain of +2.2 dB is preserved in Virtual Soundcheck mode to yield the same overall gain on that channel (because 2.2 dB of the 30 dB setting was digital gain as compared to an-alog gain).

While in Virtual Soundcheck mode, if you increase the digital gain on a channel by 6 dB (to a displayed setting of +8.2 dB), and then switch back to Stage mode, you can do one of the following:

• Apply the gain change, yielding a Stage Rack gain in-crease of 6 dB, or a final setting of +36 dB (30+6).

– or –

• Discard the gain change, leaving the original Stage input gain unchanged at +30 dB.

If you change input routing when in Virtual Soundcheck mode, those changes remain when you switch back to Stage input mode.

HDx TDM Card18

Enabling Input ModeIn Input mode, Pro Tools is the main source of audio signals for your VENUE system. Audio channels from Pro Tools ap-pear one-for-one in place of Stage inputs in the VENUE Patch-bay.

When switching back to Stage mode, previous input channel gain and PRE settings are restored. Any adjustments made in Input mode are dropped. Use Snapshots to store PRE parame-ters before entering Input mode, then recall those Snapshots after switching back to Stage mode.

To replace Stage inputs with inputs from Pro Tools:

1 Put your system into Config mode


3 Click Edit.

Adjusting Input Gain in Input Mode

In Input mode, input channel gain is adjusted using the input gain encoders. Digital gain (–20 dB to +18 dB) is available for all MADI inputs.

Exiting Input Mode

When switching from Stage mode to Input mode, all gains for MADI input channels are set to 0 dB.

When switching from Input mode to Stage mode, all digital gain settings are replaced by pre-existing Stage gain settings.

Enabling Redundant OutputsYou can install two HDx cards, or a combination of HDx and VENUE MADI cards, in an FOH Rack or a Mix Rack and oper-ate the cards in a redundant output configuration. With two HDx cards, you can record all 48 Stage inputs, plus any assign-able outputs, to two independent 64-channel Pro Tools|HD systems.

If you have an HDx card and a VENUE MADI card installed, you can record all 48 Stage inputs, plus any assignable out-puts, to a Pro Tools|HD system, and transmit the same chan-nels to an external MADI device.

To enable redundant outputs:



3 Click Edit.

4 Do one of the following depending on your configuration:

• If you have two HDx cards installed, click Enable HDx 2, an click Copy Stage 1 (or Stage for Mix Rack) Outputs to HDx 2.

It is possible to use HDx2 inputs even if a second Stage Rack (Stage 2) is not present in the system. A second Snake card must be installed in your FOH Rack.

If you want to revert to the previous configuration, in the Show Folder column select the most recent Show file from the Most Recent Changes folder, and click Load.

VENUE software 2.9 is required to enable redundant out-puts. Visit our website, www.avid.com, or see theWhat’s New in VENUE 2.9 guide for more information

5 Click the Pickoff column in the Patchbay to specify one of the following pickoff sources for each Direct Output:

• Top of Mains (indicated by a “T”)

• Pre-Fader (indicated by a lowercase “p”)

• Post-Fader (indicated by an uppercase “P”)

6 Activate the Direct Outs by clicking either channel’s In but-ton.

7 Set the level for the Direct Outs by adjusting either chan-nel’s Direct Out level control on-screen (or use the Direct Out channel encoder on the console if available).

Pro Tools

In the Inputs tab of the I/O Setup dialog:

Assign the corresponding HDx assignable output channels or channel pairs to HDx Assignable input paths in Pro Tools.

Recording Submixes

You can record submixes (also called stems) by sending VENUE system bus outputs directly to Pro Tools. Bus outputs such as Auxes, Groups, Matrixes, and PQs (if available) give you discrete level controls for the Pro Tools recording.

VENUE

On your VENUE system, do the following:

1 Assign Stage inputs and any FX Returns to the output busses you want to record in Pro Tools.

2 Go to the Patchbay page and click the Outputs tab at the top of the page.

To send the Main L/R mix pre-EQ, use the Top of Mains Di-rect Out pickoff point. This lets you capture the mix without hearing the effect of any inserted plug-ins or graphic EQs.

Recording Digital Splits

When recording digital splits of Stage input channels, assign-able inputs and outputs are freely available and independently routable.

VENUE

Go to the Options page and click the System tab to access the System Configuration page to confirm that your Stage in-puts are active. See “Enabling Digital Splits” on page 17 for more information.

Pro Tools


1 Click the Inputs tab.

2 Assign VENUE Stage1 or Stage2 input channels to HDx in-put paths in Pro Tools.

Signal Levels in Pro Tools When Recording Digital Splits

0 dB on VENUE system input meters equal –20 dBFS. This 20 dB of mixer headroom helps prevent digital clipping and distortion in live program material.

HDx does not provide independent gain control for digital splits of Stage input channel, so program material coming into VENUE at 0 dB will be recorded into Pro Tools at –20 dBFS.

For gain control of HDx outputs to Pro Tools, use Direct Out-puts to route audio channels to HDx assignable outputs, and adjust the gain on the Direct Output control for each channel.

Playing Back and Monitoring Pro Tools Tracks

You can route channels from Pro Tools to VENUE system In-put Channels and FX Returns to use click tracks or other pre-recorded material in a performance, mix down a Pro Tools ses-sion using your VENUE system, or monitor your live recording through your VENUE system.

Use the Patchbay > Inputs page to route assignable input channels 1–16 to any available Input Channels or FX Returns.

VENUE

To route assignable input channels to Input Channels and FX Returns:

1 Go to the Patchbay and click Inputs tab.

2 Click the Channels or FX Returns tab to the left of the grid to display the type of channels you want to use.

For more information on configuring your VENUE and Pro Tools systems for live recording, see the Live Recording Guide for VENUE and Pro Tools.

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 Input or FX Re-turn channels.

5 From the ACS or channel Input screens, assign routing for each HDx assignable input channel as needed:

• Assign to the main L/R bus to include Pro Tools audio in the main mix of a performance.

• Assign to a Group, Aux, Matrix, or PQ bus for submixing and monitoring.

You can leave HDx assignable input channels unassigned and still monitor them in the Solo bus and headphones.

Pro Tools


1 Click the Outputs tab.

2 Assign Pro Tools tracks to HDx Assignable output paths in Pro Tools.

Patching FWx channels to D-Show FX Returns for playback

To avoid potential feedback loops, make sure no channels are simultaneously sending to and receiving from any re-cord-enabled Pro Tools tracks.


Monitoring Recording with an HD Audio InterfaceIf your HDx installation includes a Pro Tools|HD audio inter-face, you can use the I/O Setup dialog in Pro Tools to monitor the HDx recording independently of HDx inputs and outputs.

To configure the Pro Tools system to monitor the recording, send the outputs of the Pro Tools session to the signal path that corresponds to the audio interface outputs connected to your monitoring system.

Auditioning Files in Pro Tools with HDx

The audition function in Pro Tools, used for previewing audio files in the Import Audio dialog, the Audio Regions list, the Create Fades dialog, and for previewing AudioSuite processes, is limited to the first 8 channels of the primary audio inter-face.

In an HDx-equipped VENUE system, the primary interface is always the first HDx card, so audition output goes to this de-fault output path. When you have set Inputs 1–48 to “HDx1,” audition output will be sent to the first 8 channels of your console.

It is not possible to send Pro Tools audition output to an audio interface that is connected at the end of the HDx card chain.
