Yamaha IM8-24 Manual Do Utilizador

Troubleshooting

 Owner’s Manual

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• 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.

• Assign the MC’s input channel to the MONO bus, and use 

the REC OUT section bus assign switch to select the 
MONO bus.
