Possible solution
Connect the power cord.
From the front panel, check the analog/digital input
setting.
In Double Power mode, no audio signals will be out-
put from channel B or channel D. Either turn off Dou-
ble Power mode, or re-connect the cables.
Connect the input/output cables. Also, make sure
that the cables are securely connected.
Make sure that the [MUTE] indicator is unlit. If it is lit,
turn Mute off.
Check whether the attenuator value is appropriate.
Make sure that an audio signal is being output from
the mixer or other device that is outputting audio to
the XMV.
Turn off the power, wait for the XMV to cool, and then
turn the power on again.
Make sure that the switch connected to the
[REMOTE] connector is turned on. Alternatively, use
the editor to check that this is turned on.
Check the MTX. For details, refer to the MTX
Owner's Manual.
Select "digital" input on the device. If you wish to use
the device for analog input, disconnect the device
from the YDIF network.
The device has failed. Contact your Yamaha dealer
for repair.
