Troubleshooting
Power doesn’t come on.
•Is the dedicated PW8 power supply properly plugged into
an appropriate AC power outlet?
• Is the dedicated PW8 power supply properly connected
using the included power supply cable?
The PW8 itself will not power-on unless it is correctly con-
nected via the included power cable.
• If the above checks do not identify the problem, call
Yamaha for service.
The sound of the bass drum will not move forward in
the mix.
• Could you be mixing a phase-reversed signal?
Try turning on the switch to reverse the phase. If you
are capturing the sound using multiple mics, phase rever-
sal may be causing cancellation.
How can I send the pre-EQ signal to an AUX bus for
monitoring?
• You can send the pre-EQ signal to an AUX bus by
changing an internal jumper setting. Turn the AUX PRE
switch on (pre-fader). In this case, the signal will be sent
to the AUX bus even if the input channel’s ON switch is
off.
How can I monitor the signal of a GROUP bus before I
send it to the ST L/R bus?
•With the GROUP section ON switch turned off, turning the
GROUP section AFL switch on will let you monitor the AFL
signal of the GROUP bus without sending it to the ST L/R
(and MONO) bus.
How can I send a compressed signal to the ST L/R
bus while sending the uncompressed signal to
DIRECT OUT jacks for recording?
• If you connect a compressor (external device) to the
INSERT jacks and apply compression to the signal being
sent to the ST L/R bus, the signal before the compressor
will be sent to the DIRECT OUT jacks. In this case, turn off
the IM8’s COMP control.
How can I send the TALKBACK signal only to the
intercom?
• In the TALKBACK section, turn on only MATRIX 1-2 (or
MATRIX 3-4) to send the output of MATRIX 1-2 (or
MATRIX 3-4) to the intercom.
How can I play background music from a portable
audio player?
•A standard mini-phone type 2TR IN jack is provided on
the front panel, allowing you to connect your portable
audio player via a mini-plug cable.
How can I assign the MC to the MONO bus and also
record it?
•Assign the MC’s input channel to the MONO bus, and use
the REC OUT section bus assign switch to select the
MONO bus.
