Connecting Symphony 32 and Symphony 64 with SBus

Using SBus, it’s possible to connect a Symphony 32-equipped Mac to a second Mac equipped with a

Symphony 64 system, following the steps described below. For a complete description of SBus and Symphony 64,

please consult the Symphony 64 User’s Guide.

Make PC-32 Connections

When interconnecting a Symphony 64 and 32 card via Sbus, connections must be made as shown in gure

1 at right. An Apogee hardware interface must be connected to port 1 of the Symphony 64 card, and the

Symphony 32 card must be connected to the Symphony 64’s port 2. The connection of multiple Symphony

32 cards via Sbus is not supported.

Set Symphony Source

On the Symphony 32 system, open Maestro and set Symphony Source to Symphony Card 1 (Chs 1-32).

On the Symphony 64 System, open Maestro and set Symphony Source to Symphony Card 1, Ports 1-2

(Chs 1-64). If the Maestro Control panel is greyed out, the setting may be made in the OS X utility Audio

MIDI Setup.

Set Software Sample Rate

Set the sample rate of both Macs to the same frequency. This may be done by opening a DAW session or

by opening Audio MIDI Setup, setting Properties For to Symphony 32, and setting Format to the desired

sample rate.

Verify in Maestro

Open Maestro on both Macs and verify that all hardware and SBus connections have been

detected correctly. To check for SBus connections, open the Maestro Control window and choose

Symphony:Symphony in the Interface drop down menu. The Mac to Mac icon shown in gure 2 should

appear.

Choose Symphony 32 Input and Output Labels

To facilitate the assignment of SBus I/O, it’s recommended to choose Maestro's default input and output

labels in your DAW software. To do this in Logic:

• Choose Options > Audio > I/O Labels

• Option-click the rst label in the Provided by Driver column

When Maestro’s default labels are used in your DAW, assigning one Mac’s outputs to a second Mac’s inputs

is as easy as setting output in one session to Sbus 1-2 and input in the second session to Sbus 1-2.

If your DAW software doesn’t accept Maestro’s default labels, the list below indicates how signals are routed

between Apogee hardware interfaces, Symphony 64 I/O and Symphony 32 I/O.

Apogee hardware interface inputs 1-32 > Symphony 64 inputs 1-32

Symphony 64 outputs 1-32 > Apogee hardware interface outputs 1-32

Symphony 64 inputs 33-64 (Sbus) > Symphony 32 outputs 1-32 (Sbus)

Symphony 64 outputs 33-64 (Sbus) > Symphony 32 inputs 1-32 (Sbus)
