AMPLIFIERS
Is the problem in channel one, two or both channels? Other Problems?
TIP-If your amplifier
is in protect mode, be sure to check your speaker cables and make
sure you are loading the amp appropriately. Normally, an amp will
overheat and shut down after a short time if it is trying to drive
more speakers than it was designed to handle. |
INSTRUMENT
AMPS
Are the problems with: instrument inputs, tone, volume controls,
other controls: (Chorus, Reverb, Compresion, etc.), speaker output,
operational/other??
TIP-Be sure to check
the instrument cable. Also, if at all possible, test your
instrument on another amp. You may think you have a problem
with your instrument amp when it is really your instrument. |
KEYBOARDS
Are the problems with: Keys, function buttons/display, joystick,
pitch bend, mod control, audio output, midi in/out, floppy drive,
other peripherals, operational/other??
TIP-Many problems with
todays keyboards are a result of a programming error or system
glitch. After all, they are really a computer. A call to the product
specialist at your keyboardís manufacturer may save you
from having to send it in for service. |
MIXERS/POWERED
MIXERS
Are the problems with: Input channels, master section, subgroups,
Left/right aux. send/returns-effects send/returns
monitor sends? For powered mixers-any problems with speaker outputs-see
amp section.
TIP-Be sure to eliminate
the possibility that you have a defective patch cable. Try replacing
any cable for a suspect input/output with a known good cable to
see if it solves the problem. Remember, the more you troubleshoot
and narrow down a specific problem, the less time it will take
us to find it. That equals faster turnaround and lower repair
charge! For powered mixers; normally, an amp will overheat and
shut down after a short time if it is trying to drive more speakers
than it was designed to handle. Check speaker cables! |
OTHER
Please describe the symptoms the equipment is displaying. Try
to avoid troubleshooting the problem for us. Stating that you
believe there is a short is an opinion. Describing how it sounds
before the fuse blows describes symptoms. |
