Troubleshooting Hub - Biamp Audia EXPI/O-2 Input/Output Expander

Potential Symptoms

No audio signal showing up at amplifiers in digital mode

Environment

Biamp Audia EXPI/O-2 Input/output Expander
Sportsound 500HD, 1500HD, 2000HD

Resolution

Verify Network Activity:

Look at the bottom left corner of the Ethernet port for LED identification.
- No Lights = Not connected to a switch.
- Intermitten flashing about 1 time per second or solid green light = Connected to a switch but no CobraNet connection to amplifiers. Verify configuration using DD2909756.There must be a connection in order to continue troubleshooting.
- Consistent flashing (Roughly 6 times per second) = Device has a CobraNet connection to amplifiers, proper working state.

Verify Input Signal:

Verify the input is plugged into mic/line inputs Input 1
Set mixer to output a 1kHz sine wave between 0.5VAC - 1VAC. (1 kHz sine wave). https://dakfiles.daktronics.com/downloads/Audio/CD Test Tones/
Measure the AC voltage with a digital multimeter placed between the positive and negative terminals of the main Mixer output Male XLR connector.
- If level is above or below the range in step 1, adjust it using the mixer's channel and master faders.
Measure the AC voltage at the input of the Biamp terminal block between the positive and negative terminals.
- If it reads the same voltage as the Male XLR connector, you are getting proper signal.
- If voltage reads different than the Male XLR connector, there is likely an issue, see No signal is present at analog to digital converter in the fiber box for additional troubleshooting

Verify Output Signal:

Connect a computer to the system (via DIAGNOSTIC PORT on the bottom of the fiber box or an open port on the network switch) and start CobraNet Discovery software.
If devices populate and are configured properly, close CobraNet Discovery and use proper Sportsound monitoring panel to verify the amplifiers are receiving proper signal.

Refer to How to use the Sportsound Monitor Panel Application for more information

Verify proper Biamp Configuration:

Refer to How to configure settings for a Biamp Audia EXPI/O-2 I/O Expander .
