Audio Troubleshooting
Problem
Cause Possible Solution
Volume set too
low Use the VOL UP button on the Operator Button Panel
(see Figure 5 on page 10) to raise the volume.
Faulty wiring Verify that all the wires are firmly connected to the
speakers, GVRI/O PCB, and green computer audio port.
Verify that each wire is connected to the correct port and
no wires are frayed or improperly shorting to ground.
Blown speakers Remove the grill and inspect each speaker for visible
damage. Run the Sound Test from System Tests in the
Operator Menu to verify each speaker is working.
Reversed wires A weak or low muffled sound is a sign of reversed speaker
wires. Check for reversed wires on each speaker.

faulty USB port To test a USB port, turn off the game, disconnect the
device from the port, and then connect the game dongle

supply A constant low hum in the speakers can be caused by a
faulty power supply. This could be either the external DC
power supply or the computer power supply.

outlet is properly grounded.
