Controls and Functions
XMV4280/XMV4140 Owner’s Manual 11
Switch 4 (LED DIMMER)
This specifies the brightness of the front panel indicators
and display.
Switch 5 (PANEL LOCK)
This specifies the front panel lock setting (locks all panel
operations including the [MUTE] button and attenuation
adjustments). By selecting the LOCK setting after you’ve
completed all settings, you can prevent the volume or
mute settings from being inadvertently changed.
Even if the LOCK setting is selected, you can temporarily
unlock the panel by pressing the [FUNCTION] button
and the [SELECT] A button. The panel will be re-locked
when one minute has passed without any operation being
performed, or when you once again press the [FUNC-
TION] button and the [SELECT] A button, or when you
turn off the power.
Switch 6 (IP SETTING)
This selects whether the UNIT ID value will be used as
the IP address for the unit to communicate with a com-
puter, or whether the IP address will be assigned by the
editor or the DHCP server.
Switches 7 and 8 (START UP MODE)
These specify the startup mode of the XMV.

@1 Analog input connectors

These are Euroblock 3-pin analog audio input connectors.
For details on settings for receiving audio signals via the
analog input connectors, refer to “List of Front Panel Opera-
tions” (page 20).
For details on how to attach Euroblock connectors, refer to
the “Setup” section entitled “Connecting the analog inputs
(Euroblock)” (page 13).

@2 [SPEAKERS] DIP switch

This DIP switch makes settings for the XMV’s amplifier in
groups of two channels.
Switches 1 through 4 specify the output setting for channels
C/D, and switches 5 through 8 specify the output setting for
channels A/B.
Use these switches to make the following settings.
* If this setting is chosen, input/output will be disabled for
channels B and D.
Low impedance connection / high impedance

connection (switches 1 and 5)

These select either a low impedance connection or a high
impedance connection. Set them as appropriate for the
connected speakers and the way in which the speakers are
connected. For details on connections, refer to “High-
impedance and Low-impedance Connections” (page 25).
Impedance (switches 3 and 7)
When using a low impedance connection, set these as
appropriate for the impedance of the speakers that are
connected. Check the specifications of the speakers.
For example if two 8Ω speakers are connected in parallel,
the total impedance will be 4Ω.
Double Power mode (switches 4 and 8)
When a low impedance connection is used, these
switches specify the output of the amplifier. If the 280W
{140W} setting is selected, input/output is enabled for
both channels. If the 560W {280W} setting is selected,
the output from the amplifier will be doubled, but input/
output will be disabled for channels B and D.
70V/100V (switches 2 and 6)
When a high impedance connection is used, these
switches specify the maximum output voltage (Vrms) of
the amplifier.
DIP Switches
SettingDescription
OFF Normal brightness.
ON
Reduced brightness. Use
this setting if the indicators
and the display are too
bright.
NOTE
The brightness of the [POWER] indicator will not be
reduced.
DIP Switches
SettingDescription
UNLOCK The front panel will not be
locked.
LOCK
Front panel operations
other than the power will be
locked.
DIP Switches
SettingDescription
UNIT ID
The IP address will be
specified using the UNIT ID
value.
The IP address will be
192.168.0.xxx (xxx is the
UNIT ID value).
PC
The IP address will be
specified by the editor or
the DHCP server.
DIP Switches
SettingDescription
RESUME The unit will start up nor-
mally.
INITIALIZE
The internal memory will be
initialized. For details on the
memory that will be initial-
ized, refer to “Initializing the
Internal Memory” (page 22).
