Symphony64 PCI card – User’s Guide

Troubleshooting

To quickly troubleshoot your Symphony system, open Maestro software and verify that all hardware

interfaces are correctly detected in the Interface drop down menu. If some or all interfaces aren’t detected,

please consult the symptoms and solutions described below.

Also, check the blue and white Status LEDs on the PCIe cards’ connector panels. A white LED

should be lit solidly on ALL PCIe cards and a blue LED lit solidly on ONE PCIe card (the Master card). If this

isn’t the case, please consult the LED Status grid at right. If one or both white LEDs are ashing, consult the rst

entry below.

Symphony Symptoms and Solutions

Symptom: No hardware interfaces are detected in Maestro’s Interface drop down menu and one or more white

LEDs are ashing.

Solution: Check the following clock-related items:

  • Open Audio MIDI Setup (AMS) (in the Applications > Utilities folder), set Properties For to

Symphony 64, and verify that the clock source shown on the rst hardware interface’s front

panel matches the setting made in AMS’s Clock Source drop down menu. Verify that the

sample rate of the rst interface matches the setting in AMS’s Format drop down menu.

• Verify that all other interfaces have switched to their word clock source, and are locked at the

desired sample rates.

• Verify that all ports listed in the Source drop down menu have a hardware or SBus connection.

• If the problem still has not been identied, set Symphony Source to PCI Card 1, Port 1

(Chs 1-32) and connect only 1 interface to the Master card’s Channels 1-32 port. Is this one

interface correctly detected? If so, add interfaces and enable ports one at a time until the

system is complete or a faulty component is identied.

• If one interface is still not detected after setting Symphony Source to PCI Card 1, Port 1

(Chs 1-32), open System Proler (Applications > Utilities), click on the Hardware disclosure

triangle, click on PCIe Cards, and verify that Symphony 64 appears in the Card list, and that

“Yes” appears under the Driver Installed column (see the System Proler window at right).

If Symphony 64 doesn’t appear, re-seat the PCIe card in it’s slot.

Symptom Some hardware interfaces aren’t correctly detected in Maestro.

Solution Check that the PCIe card port is enabled in the Symphony Source drop down menu

(Maestro Control window).

• Check the PC-32 connection at the PCIe card and at the X-Symphony connector.

Symptom All audio outputs are muted.

Solution Verify that the Mute checkbox is NOT checked in Audio MIDI Setup.

Symptom The rst PCIe card operates as expected, but the second PCIe card isn’t working correctly.

Solution Verify jumper settings on the second card. Verify that the card-to-card ribbon cable is installed

and rmly seated in each card’s mating connector.
