APPENDIX A: SERVICE INFORMATION
4. Replace the fuse drawer by pushing it all the way
back into the IEC socket.
5. Reconnect the line cord and turn the POWER
switch on.
If two fuses blow in a row, then something is wrong.
See the “Repair” section on the next page to fi nd
out what to do.
Bad Channel
• Is the channel GAIN turned up?
• Is the channel LEVEL turned up?
• Try the same source signal in another channel, set
up exactly like the suspect channel.
Bad Output
• IS the MAIN MIX control turned up?
• If it’s a stereo pair, try switching them around. For
example, if a left output is presumed dead, switch
the left and right cords, at the mixer end. If the left
speaker is still dead, it’s not the mixer.
Noise
• Turn the channel LEVEL controls down, one
by one. If the noise disappears, it’s either that
channel or whatever is plugged into it, so unplug
whatever that is.
Warranty Service
Details concerning Warranty Service are spelled
out in the Warranty section on page 27.
If you think your TAPCO mixer has a problem,
please do everything you can to confi rm it before
calling for service. Doing so might save you from
the deprivation of your mixer and the associated
suff ering.
These may sound obvious to you, but here are
some things you can check. Read on.
Troubleshooting
No Power
• Our favorite question: Is it plugged in? Make sure
the AC outlet is live (check with a tester or lamp).
• Our next favorite question: Is the POWER switch
on? If not, try turning it on.
•
Is the red POWER LED illuminated? If not, make
sure the AC outlet is live. If so, refer to “Bad
Channel” and “Bad Output” below.
• Is the fuse blown? If the POWER LED on the front
panel is not illuminated and you are certain that
the AC outlet is live, it is possible the fuse has
blown.
To remove and replace the fuse:
1. Disconnect the linecord from the IEC socket.
2. Remove the fuse drawer by prying it open with a
small screwdriver. It will slide all the way out.
3. Remove the fuse and replace it with an equivalent
type fuse:
1.6 amp slo-blo (T1.6 A/250V)
