XMV4280/XMV4140/XMV4280-D/XMV4140-D Owner's Manual
Possible causes
The power cord is disconnected
The analog/digital input setting is
incorrect
Double Power mode is selected
An input/output cable is discon-
nected
The mute function is turned on
The attenuator value is too low
No audio signal is being input
The protection circuit has operated
(the [PROTECTION] indicator is lit)
The unit is in standby mode
(the [POWER] indicator is flashing)
Some abnormality has occurred at
digital input from the MTX
(on XMV4280/XMV4140: [YDIF]
indicator is unlit; on XMV4280-D/
XMV4140-D: green [SYNC] indica-
tor is unlit)
"Analog" input has been selected on
a device that is connected via a
YDIF connector
(XMV4280/XMV4140 only)
The device has failed
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
output from channel B or channel D. Either turn
off Double 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.
Change to "Attenuation setting" (page 23), and
check whether the attenuator value is appropriate
on the display (page 10).
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 MTX manu-
als.
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.
