When overcurrent is detected
If for any reason the impedance falls below the specifica-
tion for the mode, the speaker output is muted to prevent
overcurrent; muting will be cancelled after approximately
one second. If overcurrent is detected after muting is can-
celled, the output will be muted again.
If DC output is detected
The power supply section will be shut down.
If excessive total current or maximum current
is detected
The output signal will be lowered.
e
[LIMIT] A–H indicators
When the limiter operates, the speaker output will be limited
and the indicator will light red. Lower the attenuator value so
that the limiter does not activate, referring to “Changing the
attenuator setting” (page 20). The limiter will operate in the
following situations.
• When an instantaneous input overload is detected
• When an input overload has been occurring for a specific
duration
• When the heat sink of the amplifier section exceeds the
allowable temperature

[SIGNAL] A–H indicators
The [SIGNAL] indicator will light in green when the input/
output signal level exceeds a certain level.

[SELECT] A–H buttons/indicators
Use these buttons to select the output channel that you want
to control. The indicator of the selected channel will light in
green.
By using these in conjunction with the [FUNCTION] button
!7
, you can change the parameter that is controlled by the
encoder. Refer to “Front Panel Operations” (page 23).
When the [PANEL LOCK] indicator
!6
is lit, front panel
operations are locked, and output channel operations are not
possible. Defeat the lock if you want to perform these opera-
tions.
y
Display
This is a 3-digit 7-segment display that shows information
such as the attenuator value of the channel selected by the
[SELECT] button
t
or the alert number (page 27).
u
Encoder
This encoder is used to edit parameters. For details on the
available parameters, refer to “Front Panel Operations”
(page 23).
When the [PANEL LOCK] indicator
!6
is lit in orange, front
panel operations are locked, and settings cannot be edited.
Defeat the lock if you want to perform these operations.
i
[MUTE] A–H indicators
When you mute an output channel by operating the unit
itself or by operations via the [REMOTE] connector
@7
or
the editor, the indicator of the corresponding channel will
light yellow.
o
[MUTE] button
By holding down the [MUTE] button and pressing the
[SELECT] button
t
, you can switch muting on/off for the
channel selected by the [SELECT] button. When muting
turns on, the [MUTE] indicator
i
will light in yellow.
When the [PANEL LOCK] indicator
!6
is lit, front panel
operations are locked, and channel mute operations are not
possible. Defeat the lock if you want to perform these opera-
tions.
!0
[POWER] indicator
This will light in green when the power supply is turned on
by the power switch
q
.
It will flash when the unit is switched to standby mode via
the [REMOTE] connector or the editor.
!1
[ALERT] indicator
This will flash or light when an abnormality occurs in the
unit.
If this is flashing, note the indication in the display and refer
to “Alert Numbers and Content” (page 27).
If it is lit, stop operating the unit. After a time, the indicator
will change to flashing, and an alert number will appear in
the display.
!2
[NETWORK] indicator (XMV8280/XMV8140 only)
This will light green if the XMV is in a linked state with an
external device via the network connector
!9
. It will flash
while data is being communicated.
!3
[YDIF] indicator (XMV8280/XMV8140 only)
This will light green when the [YDIF] connector
@0
is con-
nected normally and a valid word clock is being input.
