7.0 Troubleshooting Table

 

 

 

 

 

 

 

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 clip-

 

 

ping 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

• Verify that the user interfaces are wired correctly and to the proper zone (if there is

 

properly

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.
