External effects aren’t working. Effects processor is not plugged
in or turned on.
Make sure unit is plugged in and
turned on.
Aux outputs of mixer aren’t
connected to inputs of processor
or processor’s outputs aren’t
connected to mixer’s inputs.
Make sure the mixer’s aux outputs
are connected to the processor’s
inputs and that the processor’s
outputs are connected to the mixer’s
aux inputs.
Mixer’s effects return signal is
too low.
Turn up the output of the effects
processor or turn up the mixer’s
AUX RET A LEVEL or EFFECTS
/ AUX RET B LEVEL in the
master section.
LED meters not working. Nothing is routed to the
HDPH/CTRL RM output.
Press the desired MIX or 2 TK To
Mix button.
Computer does not see the
Multimix.
USB connection must be
established.
Unplug the USB cable and turn off
the Multimix. Turn the Multimix
back on and plug the cable back in.
If this does not work, leave the
Multimix on, turn off the computer
(do not use “restart” but instead
actually turn off the computer) and
then turn it on again.
Computer sees the Multimix
USB, but no sound is received
and/or transmitted.
Multimix USB is not set as
primary sound device.
In the computer’s Control Panel, go
to the Sounds/Multimedia area. In
the Audio section, set the default
sound recording and playback
devices to “USB audio codec.”
USB audio has crackling or
glitches, or audio plays/records at
incorrect pitch.
USB hub may be in use.
Computer configuration may be
incompatible with USB audio.
If you are using a USB hub,
disconnect the Multimix from it and
connect the mixer to the computer
directly instead.
Certain USB chipsets have design
limitations or IRQ assignment
restrictions that must be resolved
before audio can work correctly on
them. See your USB chipset
documentation for further
information if required.
No power. Incorrect or defective power
supply.
Replace with correct power supply
(only use Alesis-recommended AC
output power supply).
