TROUBLE SHOOTING AND CARING
Troubling Shooting
We do not expect you to have any problem with your
amplifier. But if you do, these suggestions might help.
Using The Feedback Filter
The FEEDBACK FILTER control lets you reduce or eliminate
squeal and other noise caused by feedback.
After you adjust LEFT/RIGHT volume, MIC 1, MIC 2, MIC 3.
MIC 4/PHONO, and CD/AUX, turn on the amplifier and any
connected sound source. If you hear any feedback, turn
FEEDBACK FILTER clockwise until you reduce or eliminate
the feedback.
NOTE:
The FEEDBACK FILTER control decreases feedback frequencies
by up to 12dB. If it does not eliminate the feedback, try
using a frequency equalizer to further decrease the feedback
frequencies.
Using The Level Meters and Clipping Indicator
The position of the LEDs on both row of the amplifier's
meters indicate the output power. The stronger the signal
the more LEDs illuminate. The maximum signal through the
PT-910 should cause the CLIPPING LED to blink at peak
music levels.
Using Speaker A/B
Press in SPEAKER A or SPEAKER B on the front of the amplifier
for the channel you want to listen to. Or, press in SPEAKER
A and SPEAKER B to listen to all connected speakers.
NOTE:
If you connected 4-ohm speakers to the amplifier, do not
set both SPEAKER A and SPEAKER B to IN (use 8-ohm speakers
only for this mode).
Replacing The Fuse
If the amplifier does not operate, you might need to replace
the fuse on the back of the amplifier with another 7-amp,
250-volt fuse, (not supplied).
IMPORTANT:
¥ Let the amplifier cool down and see if it start again before
you assume a fuse needs to be replaced.
¥ Do not use a fuse with rating other than those specified
here.
Doing so might damage your amplifier.
1.Unplug the amplifier from the AC outlet.
2.Turn the fuse holder cap on the back of the amplifier and
pull out the cap to remove the fuse.
3.If the fuse is blown, replace it. Use only an identical fuse
with the proper rating. The fuse must be 7 amps.
4.Insert the fuse into the fuse holder's socket, press the
fuse holder back into the amplifier, then turn the fuse
holder's cap clockwise to tighten it.
