Pro Tools HD Audio Interface Mode |
Connecting to Pro Tools HD PCI cards
When Symphony I/O's Audio Interface Mode is set to Pro Tools HD, one (1) Symphony I/O with up to 32 channels of input and output may be connected to each Pro Tools HD PCI card. Up to 3 Symphony I/Os may be connected.
Connect one end of an Apogee PC-32 (or Avid DigiLink) multichannel cable to the Symphony I/O Main port and the other end to a Pro Tools HD PCI Core card, as shown below. Connect additional Symphony I/Os to additional HD PCI cards.
The following Pro Tools HD PCI cards are supported.
HD Core
HD Process
HD Accel PCI
HD Accel Core
HD Accel PCIe
HD Native (see below)
Connecting to Pro Tools HD Native cards
When Symphony I/O's Audio Interface Mode is set to Pro Tools HD, one (1) Symphony I/O with up to 32 channels of input and output may be connected to each port of a Pro Tools HD Native PCI card. Connect one end of an Apogee PC-32 (or Avid DigiLink) multichannel cable to the Symphony I/O Main port and the other end to Port 1 of the HD Native PCI Core card. Connect a second Symphony I/O to Port 2.
PC-32 cable lengths of up to 30 meters between the Mac and Symphony I/O are supported at sample rates of 44.1-96 kHz. Lengths up to 5 meters are supported at sample rates of 176.4-192 kHz.
To incorporate Avid interfaces (192 I/O, 192 Digital I/O, 96 I/O, HD I/O) with one or more Symphony I/Os in a Pro Tools HD or HD Native system, the following guidelines should be followed:
Connect Symphony I/Os and Avid interfaces to different PCIe card ports.
Connect Symphony I/O's Loop Sync inputs and outputs with Avid interfaces as described in Making Hardware Clock Connections (Locking Multiple Symphony I/Os with Loop Sync).
It's recommended to connect Symphony I/O to the first PCIe card port and choosing it as the Loop Master, thus making it the clock master of the system.
A USB connection between Symphony I/O and an Intel Mac provides the link between Apogee Maestro software and Symphony I/O. See Connecting to a Mac's USB Port for details.
