User manual APOGEE AMBUS DIGI8+ CARD

[. . . ] These precautions may include 1) leaving a grounded AC cable connected to the unit; 2) grounding yourself by touching a connector on the unit; 3) leaving the card in its anti-static bag until ready to be installed and 4) handling the card only by the card edges or front panel. To install the card, remove the blanking panel from an available AMBus slot, carefully insert the card edges into the slot's guide rails and slide the card in until it has firmly mated with the slot's backplane connector. Fasten the card in place using the thumbscrews provided. Configuring Your Interface(s) As stated above, Apogee interfaces may be clocked in precisely the same manner as any Digidesign interface, if firmware version 3. 1. 0 is installed; please see Figs. [. . . ] 2) Given the exception noted above, Apogee interfaces may be clocked using either Word Clock or Super (Slave) Clock. Slave Clock I/O is found on the Dig8+ card, while Word Clock is found on the interface chassis. 3) Digidesign interfaces must be clocked with Super (Slave) Clock ONLY. 4) When using Super (Slave) clock on either a Digidesign or Apogee interface, clock cables must be connected from the Super (Slave) Clock out of the master interface to the Super (Slave) Clock in of interface 2, Slave Clock Out of interface 2 to Slave Clock In of interface 3, and so on until all interfaces have received a clock signal 5) When using Word Clock with Apogee interfaces, Word Clock out from the master interface should be connected to one side of a BNC "T" connector at the Word Clock in of interface 2. The other side of the BNC "T" connector goes to a similar BNC "T" connector on interface 3, and so on until all interfaces have received clock. Connect a 75 ohm termination plug to the unused side of the BNC "T" on the LAST interface (see Fig. 3). Page 1 Digi-8+ Card Operating Information v 3. 1. 0 Working with Pro Tools After configuring your hardware interfaces, you'll need to configure the Pro Tools application so that it recognizes the interfaces. Please see Digidesign's TDM Hardware Installation Guide for precise details, remembering that Apogee interfaces should be configured as an 888/24. Unlike meters on Digidesign interfaces, Apogee interface meters display the signal level before being sent to the Pro Tools application. We feel that input level is the highest priority in digital recording, and have built our interfaces accordingly. DIP Switches The default position for the DIP switches found on the Digi8+ card is shown at right. All switches are pressed towards OPEN 1 2 3 4 5 6 7 8 OPEN When DIP switch 2 is pressed away from OPEN (as shown at right), certain settings on the AD-8000 may be controlled from Pro Tools: Pro Tools Settings AD-8000 Settings Session Sample Rate determines Sample Rate Sync Mode sets Sync Source* Digital Format sets Source* Ch 1-2 Input sets Channel 1-2 input* * note that the only Digital formats selectable from Pro Tools are the AES and S/PDIF chassis mount inputs. be selected usersthe 16-bit Profront panel. For from of AD-8000 Tools systems, DIP switch 3 reverses odd/even audio pairs from Pro Tools when pressed away from OPEN, while DIP switch 4 reverses odd/even audio pairs to Pro Tools when pressed away from OPEN 1 2 3 4 5 6 7 8 OPEN 1 2 3 4 5 6 7 8 OPEN For Extra Credit (Clock Experts) Version 3. 1. 0 firmware makes Apogee-equipped Pro Tools systems highly tolerant of clock phase differences caused by latency, as long as all devices are ultimately clocked from the same source Signal Routing in Apogee Interfaces The AD-8000 and Trak2 interfaces share the same extremely flexible signal routing architecture, which may configured in the two general signal paths depicted on the next page. When working with Pro Tools, you'll want to set the AD-8000 to "Destination" mode and the Trak2 to "Confidence Mon ­ ON" mode, with the Digi8+ card selected as the "target" AMBus card.
