8.3.1. Pro Tools | HD Setup¶
These options are available in the Setup page for the Pro Tools | HD Expansion Card:
- Sample Rate
Displays the sample rate being output by Pro Tools. This will change depending on the Sample Rate of the Pro Tools Session.
- Clock Source
Displays either “Internal” or “LoopSync”. If the H9000 is the Clock Source in Pro Tools, then this will display “Internal”. If another HD device is the Clock Source in Pro Tools, then this will display “LoopSync” if a LoopSync connection has been established. These settings will also be reflected on H9000’s Clock menu page.
- Interface Mode
Toggles between 32 Channel mode and 16 Channel Mode. In 32 Channel Mode, the expansion card will output 32 channels through the Primary DigiLink port. Use this setting if you are connecting directly to the HD Card to take advantage of all 32 channels. In 16 Channel Mode, the expansion card will output 16 channels through both the primary and secondary port. Use this setting if you are daisy chaining into another HD interface’s secondary port since the maximum channel count per DigiLink port is 32.
- Connection Status
Indicates DigiLink port connection status. If GREEN, your HD Expansion card is connected to your HD System. If RED, your HD Expansion card is not connected or being detected by your HD System. Check your connections.
- Loop Master Status
Indicates what source is being used as the “Loopmaster” in the LoopSync. If GREEN, your H9000 is serving as the “Loop Master” to the rest of your HD System. If RED, your H9000 is clocking to another source through the LoopSync of your HD System.
- Clock Control
Allows Pro Tools permission to control your H9000’s internal clock via the HD expansion card. When using Pro Tools, toggle this on so that your H9000 can sync seamlessly with your HD System’s clocking. When not using Pro Tools, turn this off so that the H9000 will ignore any clock changes you make from Pro Tools.
When Clock Control is enabled, you will not be able to change the H9000’s clock settings regardless of whether the HD expansion card is being used or not. Turn Clock Control off to change the H9000’s clock settings.
To use Pro Tools | HD I/O with the H9000, you must connect the expansion card to your HD system via the DigiLink ports. Once this is connected, You must select the HD device as your Playback Engine in Pro Tools. In the example below, we are using an HD Native Thunderbolt to integrate it into the HD environment.
Once you have the HD device selected as your playback engine, you can now route audio to and from the H9000 via the expansion card’s DigiLink ports.
To use the H9000 as a H/W insert in Pro Tools, first you have to check your Hardware Setup page in Pro Tools to see which inserts the H9000 will correspond to.
On the left side of the Hardware Setup page, your HD devices will appear in the Peripherals window. In this case, we have our HD audio interface plugged into the Primary port, and the H9000 plugged in to the Secondary port of the HD Native. In the Peripherals window, the HD audio interface will show up as HD I/O #1 and #2, and the H9000 will show up as HD I/O #3 and #4.
Highlighting a device in the Peripherals window will allow you to view its I/O settings. In Pro Tools, the hardware inserts for HD I/O #1 and #2 will appear as A 1-16 and B 1-16. Since the H9000 is plugged into the Secondary port (HD I/O #3 and #4), its corresponding hardware inserts will be C 1-16 and D 1-16. Note that the I/O of the HD expansion card will show up in the Pro Tools Hardware Setup page as “Analog 1-16” when these are, in fact, digitally routed to the H9000.
In Pro Tools, 1st party HD interfaces will show up with their proper name (i.e. HD Native). The H9000 and other 3rd party HD devices will show up as “HD I/O” with its corresponding device number as shown above.
If a LoopSync connection has been established between your H9000 and another HD device, you will be able to use either the H9000 or the other HD device as the clock source. To select a clock source, click on the Clock Source tab and a drop down menu will appear. In the above example, selecting HD I/O #1 or #2 “Internal” will set the HD audio interface as the clock source and the H9000 will be synced to it. Alternatively, selecting HD I/O #3 or #4 “Internal” will set the H9000 as the clock source.
In the example below, the Pro Tools insert C 5-6 will route to the H9000 HD expansion I/O 5-6.
Note that the H9000 displays the expansion card I/O as a single 32-channel device, while Pro Tools divides the I/O into two separate 16-channel devices. In the above example, expansion card I/O 1-16 will appear in Pro Tools as C 1-16, while expansion card I/O 17-32 will appear in Pro Tools as D 1-16. For example, if you want to route your audio into HD expansion inputs 19-20, they will appear in Pro Tools as D 3-4.
8.3.3. Using Multiple Pro Tools | HD Expansion cards¶
In order to use more than one Pro Tools | HD expansion cards, the clocking must first be setup correctly:
If there are no other HD devices in the system, LoopSync is not needed.
Only one card can have Clock Control enabled AND it must be the card that Pro Tools selects as the “Loop Master” (Internal/AES/Word Clock).
Let’s assume that HD expansion card A is connected to the HD system’s Primary port and HD expansion card B is connected to the Secondary port:
In the Pro Tools Hardware Setup page, if HD1 or HD2 is selected as the “Loop Master,” then HD expansion card A needs to have Clock Control ON.
If HD3 or HD4 is selected as the “Loop Master,” then expansion card B needs to have Clock Control ON.
If another HD device is the “Loop Master,” either expansion card can have Clock Control enabled.
