SERVICE INFORMATION
If you think your loudspeaker has a problem, please
check out the following troubleshooting tips and do your
best to confirm the problem. Visit the Support section of
our website (www.mackie.com/support) where you will find
lots of useful information such as FAQs, documentation,
and user forums. You may find the answer to the problem
without having to send your loudspeaker away.
If you do find the problem, make sure
that you turn down the LEVEL controls
and turn off the SRM350 v2 before cor
-
recting it or changing any connections.
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 blue light on the front panel illuminated? If not,
make sure the AC outlet is live. If so, refer to “No sound”
below.
• The AC line fuse inside the chassis is blown. This is not
a user-serviceable part. Refer to “Repair” on page 16 to
find out how to proceed.
No sound!
• Is the input LEVEL control turned all the way down?
Follow the procedures in the “Quick Start” section
on page 6 to verify that all the volume controls in the
system are properly adjusted.
• Is the signal source working (and making union scale)?
Make sure the connecting cables are in good repair
and securely connected at both ends. Make sure the
output volume (gain) control on the mixing console or
preamp is turned up sufficiently to drive the inputs of
the speaker. You should be able to see the SIGNAL LED
blink on the rear panel.
• Make sure the preamp or mixer does not have a Mute
on, or a Tape or Processor loop engaged. If you find
something like this, make sure the volume/gain is
turned down before disengaging the offending switch.
One side is way louder than the other!
• Are the LEVEL controls set the same on both active
speakers?
• Check the PAN control or balance on the signal source.
It may be turned too far to one side. If you’re using a
stereo signal source, it may be delivering an out-of-bal-
ance stereo signal.
• Try swapping sides: Turn off the active speakers, swap
the input cables coming from the mixing console, turn
the active speakers back on. If the same side is still
louder, the problem may be with your active speakers or
cables between the mixer and the active speaker. If the
other side is louder now, the problem is with the mixer
or the signal source.
Poor bass performance
• Check the polarity of the connections between the
mixer/preamp and the active speakers. You may have
your positive and negative connections reversed at one
end of one cable, causing one SRM350 v2 to be out-of-
phase.
Bad sound!
• Is it loud and distorted? Follow the procedures de-
scribed in the “Quick Start” section to verify that the
levels are set properly.
• Is the input connector plugged completely 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.
