Troubleshooting
Problem What to do
• No power • Turn on power.
• Make sure the power cord is plugged in.
• Power is on, but no
sound
• Make sure the source is turned on
• Verify that there is an input signal from the source. The audio input signal
indicator on the front of the chassis should be green.
• Check the output signal indicators on the system controls. If the LED is not lit
(green), the output levels may be too low.
• Check the source routing.
• Check the cable connections from the source to the chassis.
• Verify the user interfaces are of the right type for the operating mode
selected.
• Power is on, but
sound is low
• Verify that the audio input indicator is lit (green). If it is not lit, increase the
source output or increase the input gain.
• Sound is distorted • Verify that the Input clipping indicators are not lit (red). If an LED is red,
reduce the source output level or reduce the input gain.
• Verify that the Output clipping indicators are not lit (red). If one is red, but
Input clipping LEDs are not, reduce the output gain.
• If the input source signal is clean when it enters the chassis and the Input and
Output indicators are green, verify that the loudspeakers are not overdriven
or damaged.
• Unnatural sound • Verify that the correct EQ is selected for speakers connected to the Output
channel.
• Verify that the speakers are wired correctly (+ to + and - to -).
• User interfaces do not
operate properly
• Verify that the user interfaces are wired correctly and to the proper zone (if
there is more than one zone).
• Check the wiring for breaks or shorts in the cable.
• Verify the user interfaces are of the right type for the operating mode
selected.
