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:

SIOmkII_TFT_Dante AIM

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.
