Warranty Service
If you think your Mix Series mixer 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.720trees.com) where
you will find lots of useful information such as FAQs
and other documentation. You may find the answer
to the problem without having to send your mixer away.
Troubleshooting
Power
• Our favorite question: is the power switch on?
Ha, fooled you! There is no power switch!
• Is the external power supply securely plugged
into the power connector on the back of the
Mix Series mixer?
• Is the external power supply securely plugged
into an AC power strip? Make sure the power to
the power strip is turned on.
• Are all the lights out in the building?
Bad Channel
• Is the gain set correctly?
• Is the level knob turned up?
• Try the same source signal in another channel,
set up exactly like the suspect channel.
• Check that the pan knob is set correctly.
• Check the EQ and the low-cut switch.
Bad Output
• 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 left main
out, unplug the RCA and CR left outputs. If the
problem goes away, its not the mixer.
• If a left speaker is presumed dead, switch the
left and right cords, at the mixer's main outs.
If the left speaker is still not working, it’s not
the mixer.
Noise
• Turn the channel level and aux return knobs
down, one by one. If the sound disappears,
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.
