# Connecting to a Symphony 64 PCIe Card

| ##  | ## Symphony Audio Interface Mode

When audio interface mode is set to Symphony, one (1) Symphony I/O with up to 32 channels of input and output may be connected to each port of a Symphony 64 PCI card.

Connect one end of an Apogee PC-32 cable (supplied with the PCI card) to the first Symphony I/O Main port and the other end to the Symphony 64's Channels 1-32 port. Connect a second PC-32 cable to the second Symphony I/O Main port and the other end to the Symphony 64's Channels 33-64 port. See the diagram below.

IMPORTANT - Once all PC-32 connections are made, open Maestro 2, click on the System Setup and enable all connected Symphony 64 ports using the Symphony Source drop down. For example, if interfaces are connected to both the Symphony 64 card's "Channels 1-32" and "Channels 33-64" ports, set Symphony Source to PCI Card 1, Port 1-2 (Chs 1-64).

Connecting 16X and Rosetta Series Interfaces

With Symphony I/O Release 4.2 and greater, it's possible to integrate Apogee 16X and Rosetta Series interfaces into your Symphony system. Please follow the guidelines listed below:

> • Note that at the current time, the use of only 1 Symphony 64 card is supported regardless of the interface connected.
> • When connecting legacy Apogee interfaces to a Symphony 64 or Mobile card, ensure that the interfaces are connected in a supported hardware combination, as listed below. With a Symphony 64 card, itʼs possible to connect one supported combination to each port.
> • When connecting both Symphony I/Os and legacy Apogee interfaces to a Symphony 64 card, connect the Symphony I/O to Port 1 Channels 1-32 port and legacy interfaces (in a supported combination) to the Port 2 Channels 1-64 port.
> • Legacy Apogee interfaces donʼt include Loop clock functionality (as found on Symphony I/O). Thus, when legacy interfaces are connected to a Symphony 64 card, the “Use Loop Sync” checkbox does not appear and Loop sync functionality is defeated on the Symphony I/O. See "Making Clock Connections - Locking multiple interfaces using a Star clock configuration".

Maestro cannot distinguish between an AD16X and DA16X when the interface is set to Advanced routing mode. Similarly, Maestro can't distingish between a Rosetta 800 and Rosetta 200. In order that audio paths displayed in the Input and Output Routing tabs correspond to the actual hardware I/O, specify the connected device in the Device Settings > Device Type drop down. If neither a 16X Series in Advanced routing nor a Rosetta is connected, the Device Type drop down is not displayed.

The following combinations of legacy interfaces are supported. See the Symphony 64 Userʼs Guide v1.1 for connection diagrams.

# Connecting to a Symphony Mobile Card

When Symphony I/O's Audio Interface Mode is set to Symphony, up to 32 channels of Symphony I/O input and output may be connected to a Symphony Mobile PCI card.

Connect one end of an Apogee PC-32 cable (supplied with the PCI card) to the Symphony I/O Main port and the other end to the Symphony Mobile card, as shown below.

PC-32 cable lengths of up to 30 meters between the Mac and Symphony I/O are supported at sample rates of 44.1-96 kHz. Lengths up to 5 meters are supported at sample rates of 176.4-192 kHz.

Symphony I/O Release 4 - The connection of one Symphony I/O to each port of one Symphony 64 card or to a Symphony Mobile card is currently supported.
