5.2 Problem: No Sound
Indication: On LEDs not lit
Clip LEDs not lit
•Check AC plug.
•Confirm that AC outlet works by plugging in another device.
Indication: On LEDs lit
Signal LED not lit
•Make sure the signal source is operating and try another cable.
•Check position of Volume Pots.
Indication: On LEDs lit
Signal LEDs responding to signal level
•Check the speaker wiring for breaks.
•Try another speaker and cable.
Indication: On LED(s) sequence
The amplifier is in protective muting. Refer to On LED flashing sequences
table to find out the cause for the mute.
•Overheating will cause protective muting.
•If the fans aren’t running the amplifier requires servicing
5.3 Problem: No Sound or Sound Is Too Low
Indication: On LED not or sporadically lit
Signal LED not lit
Clip LED lit
Under Impedance Limiter is active. The load impedance is abnormally low
or shorted.
• Unplug each speaker one-by-one. If the On LED indicates normally when
you disconnect a cable, that cable or speaker is shorted.
• Take care not to use too many speakers in parallel, which would result in
an impedance that is too low for normal operation!
Indication: On LED(s) sequence
Please refer to the On LED flashing sequences table to find out which
protection is active. High temperature will cause an attenuation of output
level! DC will cause the amp to mute or shut down.
• If the On LED sequence indicates “DC, Input Signal Fault”, switch off the
D-POWER 7 and unplug the amp to disconnect it from the signal source. If
the On LED shows the same sequence when the D-POWER 7 is switched
on again, the amp will need to be serviced by a qualified technician.
All other On LED sequences that shut down or mute the D-POWER 7
indicate a serious internal fault. At this point, turn the D-POWER 7 off,
remove AC power and have the amplifier serviced by a qualified tech-
nician.
5.4 Problem: No Channel Separation
• Check the mode indicators on the front panel and make sure the mode
selector on the rear panel is in the Stereo-position.
• Make sure other equipment in the signal path such as mixers and
preamps are set for stereo, not mono.
5.5 Problem: Distorted Sound
Indication: On LED lit
Signal LED responding to signal level
Clip LED lit only green
• A faulty speaker or a loose connection could cause this. Check the wir-
ing and the speakers systematically (i.e. step by step) and replace them
if nec essary.
• The signal source might be clipping. Keep the D-POWER 7 volume pots
at least halfway up so that the source does not have to be overdriven.
• Keep the D-POWER 7 Volume Pots at least halfway up and try changing
input sensitivity from 1,4 V to 32 dB or 26 dB with the Gain Selector on
the rear.
