Ground loops are probably the most
common cause of hum and buzz in
sound reinforcement systems and other
audio products. A ground loop usually
occurs if the separate pieces of
equipment are plugged into different AC
circuits. Also, if the audio wiring is placed too close
to the power cords, hums or buzzes can bleed into
the system. Still, improperly maintained power and
audio cables are yet another cause of bothersome
noise. In order to help minimize stray hums and
buzzes, here are some helpful hints.
1. Keep all electronics connected to the sound
system on the same electrical circuit.
2. Keep audio signals cables away from the AC
power cords.
3. Use balanced cables when applicable.
4. Always plug the PowerStage 100 into a
grounded AC electrical outlet.
5. Be sure to use properly maintained cords and
cables with the PowerStage 100.
The PowerStage 100 is covered in a
tough, soil resistant synthetic
indoor/outdoor carpet for long life and
lasting good looks. To clean the
carpeted cabinet, use a brush to wipe
away any smudges or dirt. For stubborn stains, a
sponge with a light soapy solution may be used.
Avoid spilling liquids on the operating surface, heat
sink, grille, volume and tone controls, switches and
speakers. ALWAYS unplug the PowerStage 100
before cleaning it and wait until it has dried before
plugging in the PowerStage 100.
If the PowerStage 100 is set up but
does not function, please check the
following items:
• Is the PowerStage 100's power cord properly
plugged into an electrical outlet?
• Is the power cord properly plugged into the Power
Stage 100's Supply Cord Jack?
• Is there power at the outlet?
• Does your instrument have power?
• Are the volume control knobs on the Power
Stage turned above the Min position?
• Are the volume control knobs on your instruments
turned above their minimum position?
• Is the mic/instrument properly plugged into the
Power Stage 100?
• Is the mic/instrument turned on?
• Are your audio cables frayed, cut or damaged?
• If using a condenser mic, is the phantom power
turned on?
• If using an effects processor, is the "Y" line cord
properly connected?
If after checking all of the above the PowerStage
100 is still not performing correctly, consult your
authorized Fender Service Center.
