SERVICE INFORMATION

Warranty Service

Details concerning warranty service are spelled out
on page 11 of this manual.
If you think your loudspeaker has a prob lem, please do
everything you can to con fi rm it before calling for service,
in clud ing reading through the following Trou ble shoot ing
sec tion. Doing so might save you from being de prived of
your Mack ie loudspeaker.
Of all Mackie prod ucts returned for ser vice (which is
hardly any at all), many are coded "CND" — Could Not
Duplicate— which usually means the problem lay some-
where else in the sys tem. The following trou ble shoot ing
tips may sound obvious, but here are some things you
can check:

Troubleshooting

No sound
• Are the level controls on the mixer or amplifi er
turned all the way down? Follow the procedures in
the "Quick-Start" section on page 4 to verify that
all the vol ume controls in the system are properly
ad just ed.
• Is the signal source working (and making union
scale)? Make sure the con nect ing cables are in good
repair and se cure ly connected at both ends.
• Make sure the mixer does not have a Mute on or a
Processor loop en gaged. If you fi nd something like
this, make sure the volume/gain is turned down
before disengaging the offending switch.
Poor bass performance
• Check the polarity of the connections between the
mixer and the loud speak ers. You may have your
positive and negative connections re versed at one
end of one cable, causing one loud speak er to be
out-of-phase.
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 plete ly into the
jack? Make sure all con nec tions are secure. It's a
good idea to periodically clean all electrical con-
nec tions with a non-lu bri cat ing electrical contact
cleaner.
