VLZ3

Details concerning the Limited Warranty are spelled 

out on page 27 of this manual.

If you think your 1402-VLZ3 has a problem, please 

check out the following troubleshooting tips and do your 
best to confi rm the problem. Visit the Support section of 
our website (www.mackie.com) where you will fi nd lots 
of useful information such as FAQs, documentation and 
user forums. You may fi nd the answer to the problem 
without having to send your mixer away.

• 

Is the MUTE/ALT 3–4 switch in the correct 
position?

• 

Is the fader turned up?

• 

Try unplugging any INSERT devices (Channels 
1–6 only).

• 

Try the same source signal in another channel, 
set up exactly like the suspect channel. 

• 

Is the associated level knob (if any) turned up?

• 

If it’s one of the MAIN OUTS, try unplugging 
all the others. For example, if it’s the 1⁄4" 
Left Main out, unplug the RCA and XLR Left 
outputs. If the problem goes away, its not the 
mixer.

• 

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.

• 

Turn the channel GAIN and STEREO  RETURN 
knobs down, one by one. If the sound disap-
pears, 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.

• 

Unplug the power cord and check the fuse.
