5.1 Problem: No Sound
Indication:
On LEDs not lit
Signal LEDs not lit
Clip LEDs not lit
Check AC plug.
Confirm that AC outlet works by plugging in another device.
Indication:
I-Out LEDs are lit
Signal LEDs not lit
Make sure the signal source is operating and try another cable.
Check position of volume pots.
Indication:
I-Out LEDs are lit
Signal LEDs responding to signal level
Check the speaker wiring for breaks.
Try another speaker and cable.
Indication:
Signal LEDs show red (Protect Mode)
Overheating will cause protective muting. Check for proper
ventilation.
5.2 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.
5.3 Problem: Distorted Sound
Indication:
I-Out LEDs are lit
Signal LEDs responding to signal level
Clip LEDs not lit
A faulty speaker or a loose connection could cause this. Check the
wiring and try another speaker.
The signal source might be clipping. Keep the D-POWER volume
pots at least halfway up so that the source does not have to be
overdriven.
5.4 Problem: Hiss
Unplug the amplifier input to confirm that the hiss is coming from
the source or from a device upstream. Erratic or popping noises
indicate an electronic fault in the offending unit.
To keep the noise floor low, operate the primary signal source at full
level, without clipping.
Avoid boosting the signal further between the source and the am-
plifier.
5.5 Problem: Squeals and Feedback
Microphone feedback should be eliminated with mixer controls. If
noise continues to build up with no microphone gain, there is a seri-
ous fault in the signal processors or cables. Working in succession
from the signal source towards the amplifier and check each device
in the signal path by reducing its gain or by unplugging it.
