Connecting & Configuring the X-Digi-Mix-equipped
Apogee Interface
With a few simple rules it’s possible to determine the connections needed for virtually any
combination of Apogee and Digidesign interfaces.
1) The unit connected to the Digidesign PCI card installed in the computer’s first PCI slot
(usually a Mix Core or d24 card) is the clock master of the entire system. We recommend
that an Apogee unit be installed as the Master, allowing the entire system to benefit from
Apogee’s Low Jitter Clock.
2) Units connected to other PCI cards (or the “B” side of a Y cable connected to the first PCI
card) must be clocked externally.
a. Apogee interfaces should clock to a word clock from the Master unit (if the
Master is an Apogee unit) or to a clock in the Digidesign Peripheral Cable (if the
Master is a Digidesign unit).
b. Digidesign interfaces can only clock to a Superclock (256 times the sample rate) signal.
3) When an Apogee interface is Master and a Digidesign interface is Slave, connect
Superclock Out from the X-Digi-Mix Card to Superclock In on the Digidesign interface.
4) When a Digidesign interface is Master and an Apogee interface is Slave, no clock
connections are needed; set SAMPLE RATE on the slave Apogee interface to “EXT” and
SYNC to “OPTION”.
To illustrate the necessary connections between an X-Digi-Mix-equipped Apogee interfaces, other
Digidesign compatible interfaces and Digidesign PCI cards, the Rosetta 800 is shown below in a
variety of possible setups.
• When connecting only 1 interface to a Pro Tools system, ensure that it is
connected to the Digidesign Mix Core or d24 card. In this configuration the
Rosetta 800 is the clock master for the entire system.
• When the Rosetta 800 is connected to the Mix Core or d24 card, the
Rosetta 800’s SAMPLE RATE and SYNC parameters are determined by
settings in the Pro Tools software. Please see the section of this manual
entitled “Working With Pro Tools” for more details.
