Connecting Multiple Apogee Interfaces

PC-32 Connection to Apogee Interfaces

Awidearrayofsysteminput/outputcongurationsmaybeachievedaccordingtothe

Apogee interfaces used, the order in which interfaces are connected, and the internal routing

conguration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congurations,

as well as the mapping of interface I/O to the 32 channels of Symphony Mobile I/O for each

possibleconguration.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rst):

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•

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.
