Symphony PCI card – User’s Guide
PC32 Connections
It’s possible to connect Apogee AD16X, DA16X, Rosetta 800 and Rosetta 200 interfaces to Sym-
phony PCI cards in a wide array of configurations for a total of 32 channels of simultaneous input
and output per PCI card. To “map” the I/O of interfaces to the Symphony PCI card I/O in the most
efficient manner possible, please use the following guidelines to determine the order in which inter-
faces are connected:
1. Connect interfaces by pairs:
a. AD16X-DA16X (standard routing) = 16 analog in X 16 analog out;
b. Rosetta 800/200 x 2 = 16 analog/ digital in X 16 analog out (R800);
= 4 analog or digital in X 4 analgo out (R200);
c. AD16X-DA16X (advanced routing) = 16 analog in +16 digital in X 16 analog out + 16
digital out
2. Per Symphony PCI card, it’s possible to connect:
a. 2 pairs of AD-DA16Xs (standard routing) or,
b. 2 pairs of Rosetta 800s/200s or
c. 1 pair of AD-DA16Xs (advanced routing).
The chart beginning on page 8 depicts all possible combinations of Apogee interfaces per PCI card
and how connected interfaces are mapped to the PCI card I/O.
Regardless of the Apogee hardware used, PC 32 cables should be connected as shown below in
Figure 3, where the Symphony PCI card is connected to the first unit’s X-Symphony Main port, the
first unit’s Thru port is connected to the second unit’s Main port, and so on until all interfaces are
connected.
