Appendix A: Service Info; Troubleshooting - Mackie SR40.8 Owner's Manual

APPENDIX A: Service Info

Details concerning Warranty Service are
spelled out on the Warranty Card included
with your mixer (if it's missing, let us know
and we'll rush one to you).
If you think your mixing board has a prob-
lem, please do everything you can to confirm
it before calling for service. Doing so might
save you from the deprivation of your mixer
and the associated suffering.
Of all Mackie products returned for service
(which is hardly any at all), roughly 50% are
coded "CND" — Could Not Duplicate, which
usually means the problem lay somewhere other
than the mixer. These may sound obvious to
you, but here's some things you can check:

TROUBLESHOOTING

Bad Channel
• Is the mute switch in the correct position?
• Is the gain turned up?
• Try unplugging any insert devices.
• Try the same source signal in another
channel, set up exactly like the
suspect channel.
Bad Output
• Is the associated level knob (if any) turned up?
• If it's an aux send or sub problem, is the
FLIP switch set correctly?
• 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 problem
switches sides, it's not the mixer.
Noise
• Mute the channels and aux returns one by
one. If the sound disappears, it's either that
channel or whatever is plugged into it, so
unplug whatever that is. If the noise
disappears, it's from your whatever.
Power
• Our favorite question: Is the power switch on?
• Are all of the status LEDs on?
• Check the fuses. Please refer to the power
supply documentation to change the fuse.
REPAIR
Service for the U.S. versions of our mixers is
available only from one of our authorized
domestic service stations or at the factory, lo-
62
cated in sunny Woodinville, Washington. (Ser-
vice for mixers living outside the United States
can be obtained through local dealers or dis-
tributors.) If your mixer needs service, follow
these instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883, 8am
to 5pm PST, to explain the problem and
request an RA number. Have your mixer's
serial number ready. You must have a
Return Authorization number, before
you can obtain service at the factory or
an authorzed service center.
3. Set aside the power cord, owner's manual,
or anything else that you'll ever want to see
again. We are responsible for the return of
the mixer only.
4. Pack the mixer in its original package,
including endcaps and box. This is VERY
IMPORTANT. When you call for the RA
number, please let Tech Support know if
you need new packaging. Mackie is not
responsible for any damage that occurs due
to non-factory packaging.
5. Include a legible note stating your name,
shipping address (no P.O. boxes), daytime
phone number, RA number and a detailed
description of the problem, including how
we can duplicate it.
6. Write the RA number in BIG PRINT on top
of the box.
7. Ship the mixer to us. We recommend
United Parcel Service (UPS). We suggest
insurance for all forms of cartage. Ship to
this address:

8. We'll try to fix the mixer within three
business days. Ask Tech Support for
current turn-around times when you call
for your RA number. We normally send
everything back prepaid using UPS BLUE
(Second Day Air). However, if you rush
your mixer to us by Air Shipment, we'll
treat it in kind by letting it jump to the
head of the line, and we'll also ship it back
to you UPS RED (Next Day Air). This
paragraph does not necessarily apply to
non-warranty service.
