Condition: No power to the amplifier
Possible Reason:
The amplifier power switch may be off.
+
The amplifier may not be plugged into the power receptacle.
+
Confirm that the AC outlet works by plugging in another device. If too many amplifiers
+
are used on one outlet, the building's circuit breaker may trip and shut off power.
An overload may cause the AC ckt protector trip. Check the AC ckt protector, if ckt
+
protector is in Tripp condition then reset it by pushing the knob.
Condition: Low output
Possible Reason:
Check if the level of the input signal is too low.
n
Check the signal source is operating and the input cable is intact.
n
The channel volume control setting is too low.
n
Condition: No Sound
Possible Reason:
The amplifier may be in mute mode due to speaker impedance mismatch or output
n
short circuit, DCP
Check the speaker impedance and speaker wiring for stray strands or breaks in the
n
insulation.
Correct the fault and then use the amplifier.
n
To restore normal operation, turn down the volume control, switch OFF the set for few
n
seconds and switch ON again. Increase the volume control slowly for the desired
output.
Condition: No Sound
Possible Reason:
The amplifier may be in mute mode due to output short circuit, overloading or poor
n
ventilation resulting in the rise in temperature either of output devices or power
transformer as indicated by respective LEDs to unsafe region.
Switch off the amplifier to cool down.
n
Check if the fan is working, proper ventilation is provided and output connections
n
are as recommended, remove the fault if any.
This could be due to wrong speakon connections or faulty speakers.
n
Check the output speakon connections as per fig. 3 on page no. 13 (Output
n
Connections for Stereo, Mono Mode).
To restore normal operation, turn down the volume control, than switch ON the set
n
and increase the volume control for desired output.
Condition: NO Sound
Possible Reason:
Amplifier has gone to protect mode due to high signal level, high temperature or
n
output short or overloading.
Check the level of signal from input source. If it is high then reduce the input signal
n
level and than switch ON the amplifier and increase volume slowly.
The amplifier should never be operated at a level which causes the clip LEDs to
n
illuminate continuously. It will give distorted sound.
Also check the impedance of speakers, shorting of speaker connections if any.
n
Rectify the fault and then switch ON the amplifier for normal operation.
