REPAIR

Service for the SRM450 is available only

from one of our authorized domestic ser-
vice stations or at the factory, located in
sunny Woodinville, Washington. Service
outside the United States can be obtained
through local dealers or distributors.

If your SRM450 needs service, please fol-

low 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
in detail. They will ask you all sorts of
impertinent questions in the hope of
sorting out the problem. If it appears
that the SRM450 needs repair, request
an RA (Return Authorization) number.
Have your speaker’s serial number
ready. You must have an RA number
before you can obtain service at the
factory or an authorized service center.

3. Keep this owner’s manual. We don’t

need it to repair the active speaker.

4.

Pack the loud-

speaker in its original
package, including
protective wrap, 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 prob-
lem, including how we can duplicate it.

6. Write the RA number in 

BIG PRINT

on top of the box.

7. Ship the active speaker to us. We

recommend United Parcel Service
(UPS). We suggest insurance for all
forms of cartage. Ship to this address:

SERVICE DEPARTMENT

16140 Wood-Red Rd. NE, Ste 5

Woodinville, WA 98072

8. We’ll try to fix the speaker within three

business days. Ask Tech Support for the
latest turnaround 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 speaker to us by Next
Day Air, we’ll treat it in kind by ship-
ping it back to you UPS RED (Next Day
Air). This paragraph does not necessar-
ily apply to non-warranty service.

CARE AND
MAINTENANCE

Your Mackie active speakers will provide

many years of reliable service if you follow
these guidelines:

Avoid exposing the
active speakers to
moisture. If they are set
up outdoors, be sure they
are under cover if you

expect rain or you live in Washington.

• Avoid exposure to extreme cold (below

freezing temperatures). If you must
operate the active speakers in a cold
environment, warm up the voice coils
slowly by sending a low-level signal
through them for about 15 minutes
prior to high-power operation.

• Use a slighty damp cloth with a mild

soap solution to clean the cabinets. Only
do this when the power is turned off.
Avoid getting moisture into any of the
openings of the cabinet, particularly
where the drivers are located.
