Poor sound
• Is it loud and distorted? Make sure that
you’re not overdriving a stage in the
signal chain. Verify that all level controls
are set properly.
• Is the input connector plugged com-
pletely into the jack? Be sure all
connections are secure. It’s a good idea
to periodically clean all electrical
connections with a non-lubricating
electrical contact cleaner.
Noise
• Make sure all connections to the active
loudspeakers are good and sound.
• Make sure none of the signal cables are
routed near AC cables, power trans-
formers, or other EMI-inducing devices.
• Is there a light dimmer or other SCR-
based device on the same AC circuit as
the SR1530? Use an AC line filter or
plug the SR1530 into a different AC
circuit.
Hum
• Try disconnecting the cable connected
to the
MAIN INPUT
jack. If the noise
disappears, it could be a “ground loop,”
rather than a problem with the SR1530.
Try some of the following troubleshoot-
ing ideas:
• Use balanced connections throughout
your system for the best noise rejection.
• Whenever possible, plug all the audio
equipment’s linecords into outlets which
share a common ground. The distance
between the outlets and the common
ground should be as short as possible.
If your SR1530 needs service, please fol-
low these instructions:
1. Review the preceding troubleshooting
suggestions. Please.
2. Call Tech Support at 1-800-258-6883,
7am 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 SR1530 needs repair, request
an RA (Return Authorization) number.
Have your loudspeaker’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 user’s manual. We don’t need
it to repair the loudspeaker.
4. Pack the loudspeaker in its original
packaging, including protective wrap,
endcaps, and box. This is very impor-
tant. 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 loudspeaker to us. We recom-
mend United Parcel Service (UPS). We
suggest insurance for all forms of
cartage. Ship to this address:

8. We’ll try to fix the loudspeaker 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 ORANGE (Third Day Air).
However, if you rush your loudspeaker
to us by Next Day Air, we’ll treat it in
kind by shipping it back to you UPS
RED (Next Day Air). This paragraph
does not necessarily apply to non-
warranty service.
