

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.



The power supply section will be shut down.



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

r [SIGNAL] A–H indicators

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

*1 For details on switching the indicator between input and 

output, refer to “Front Panel Operations” (page 23).

*2 Depends on the condition. Refer to “[SIGNAL] Indicator Lit 

t [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.
