# 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).

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.
