Symphony I/O Mk2 Dante + Pro Tools HD Routing

Dante + Pro Tools HD Audio Interface Mode

Symphony I/O Dante + Pro Tools HD offers powerful routing options between Symphony I/O modules, Pro Tools HD, and your Dante network.

To set Symphony I/O to Dante + Pro Tools HD audio interface mode from the front panel OLED:

1. Tap Settings (gear icon).

2. Tap the Setup tab at the top of the screen.

3. Tap the Audio Interface Mode button, then tap “Yes” in the on-screen prompt. If the Thunderbolt option card is installed, the button toggles through the available AIMs in the order Dante - Dante + PTHD - Thunderbolt. Thus, it may be necessary to set the Audio Interface Mode twice to arrive at the desired AIM.

Routing TO Pro Tools HD

When Symphony I/O is set to Dante + PTHD audio interface mode, it's possible to route up to 32 channels to the Pro Tools session inputs. The source of these inputs may be routed from either Symphony I/O's 32 I/O module inputs (when 2 modules are installed) or from 32 Dante Receive channels. 

Routing from I/O modules inputs or Dante Receive inputs is set on the front panel OLED in Settings (1) > Setup tab (2), using two buttons (3) labelled To PTHD 1-16 and To PTHD 17-32. Each button sets two banks of 8 channels: To PTHD 1-16 sets the source for Pro Tools inputs 1-8 and 9-16, while To PTHD 17-32 sets the source for Pro Tools inputs 17-24 and 25-32.

In the example shown above, To PTHD 1-16 is set to Analog 1-8, Dante 9-16 and To PTHD 17-32 is set to Dante 17-24, Dante 25-32. With this setting, the first 8 I/O module analog inputs are routed to Pro Tools inputs 1-8 while Dante Receive 9-32 is routed to Pro Tools inputs 9-32.

To route all Dante Receive channels to Pro Tools inputs, set To PTHD 1-16  to Dante 1-8, Dante 9-16and To PTHD 17-32  to Dante 17-24, Dante 25-32.

 To route all I/O module inputs to Pro Tools inputs, set To PTHD 1-16  to Analog 1-8, Digital 9-16 and To PTHD 17-32  to Analog 17-24, Digital 25-32.

If only one I/O module is installed, then To PTHD 17-32 defaults to Dante 17-24, Dante 25-32.

Routing FROM Pro Tools

Audio FROM the Pro Tools session is routed simultaneously to I/O module outputs and Dante Transmit channels. This routing is fixed.

Custom Labels in Dante Controller & Pro Tools HD

Once To Pro Tools routing has been set, it's recommended to create custom labels for both the Dante Controller Routing grid and Pro Tools I/O Setup. This will make routing between your Pro Tools session, the Dante network, and Symphony I/O modules simple to implement.

The Dante Controller Routing grid custom labels are shown below based on the To Pro Tools settings shown above. 

  • The first 8 Dante Receivers are set to N.A, or not available. With To Pro Tools configured so input 1-8 are sourced from Symphony I/O modules, Dante Receivers 1-8 aren't routed anywhere.
  • All Pro Tools outputs are simultaneously transmitted to the Dante network and routed to I/O module outputs.

In Pro Tools I/O Setup, the custom Input labels shown below are based on To PTHD 1-16 is set to Analog 1-8, Dante 9-16.

Custom Output labels shown below are based 1 I/O module installed - Outputs 1-16 are routed to Dante Transmit and I/O modules outputs simultaneously.
