Details concerning the Limited Warranty are spelled 

out on page 31 of this manual.

If you think your 1642-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.

• 

Are the channels assigned to the correct mix 
(1-2, 3-4, L-R )?

• 

Is the fader up?

• 

Try unplugging any insert devices from the 
INSERT [4) jacks.

• 

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

• 

Is the level control (if any) turned up?

• 

If you’re listening to the C-R OUTS [9] or 
PHONES [10] outputs, has a SOURCE selection 
been made?

• 

If it’s one of the MAIN OUTS [14], try unplug-
ging its companion. For example, if it’s the 1/4" 
output, unplug the RCA output. If the problem 
goes away, it’s 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 left is still dead, it’s not the mixer.

• 

Unplug everthing from the MAIN INSERT [13].

• 

Turn the channel faders 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.
