Connecting Multiple Apogee Interfaces

PC-32 Connection to Apogee Interfaces

A wide array of system input/output configurations may be achieved according to the
Apogee interfaces used, the order in which interfaces are connected, and the internal routing
configuration of each interface.
For example, it's possible to connect two AD16Xs and 2 DA16Xs (all set to Standard routing) to
provide 32 analog inputs and 32 analog outputs. When the AD/DAs are set to Advanced routing,
it's possible to connect 1 AD16X and 1 DA16X, providing 16 channels of analog I/O and 16
channels of digital I/O.
The Interface Connection Chart on pages 10-15 depicts all possible interfaces configurations,
as well as the mapping of interface I/O to the 32 channels of Symphony Mobile I/O for each
possible configuration. For example, the chart entry for the connection of 1 AD16X and 1 DA16X
(set to Advanced routing) indicates the following (when the AD is connected first):
• Symphony inputs 1-16 correspond to the AD's analog inputs 1-16;
• Symphony outputs 1-16 correspond to the AD's digital outputs 1-16;
• Symphony inputs 17-32 correspond to the DA's digital inputs 1-16;
• Symphony outputs 17-32 correspond to the DA's analog outputs 1-16
AD-16X & DA-16X
Keep in mind that the Symphony Mobile driver makes 32 channels of I/O available at all times
to CoreAudio compatible software regardless of the number of Apogee hardware channels
connected. Thus, 32 channels of Symphony I/O are presented in the software I/O selection,
even if they're not all used.

standard and advanced option routing.
