Switches 7 and 8 (START UP MODE)
These specify the startup mode.

@4 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 "Front Panel Operations"
(page 23).
For details on how to attach Euroblock connectors, refer to
the "Connections and Setting Up" section entitled "Connect-
ing the Analog Inputs (Euroblock)" (page 16).
@5 [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 and D, and switches 5 through 8 specify the output setting
for channels A and B.
Use these switches to make the following settings.
Description
280W{140W}, 8Ω
560W{280W}*, 8Ω
Low-impedance
Connection
280W{140W}, 4Ω
560W{280W}*, 4Ω
70V, 250W{125W}
High-impedance
Connection
100V, 250W{125W}
* 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 30).
Description
The unit will start up nor-
mally.
The internal memory will be
initialized. For details on the
memory that will be initial-
ized, refer to "Initializing the
Internal Memory" (page 25).
Switches 1–4
(channels C, D)
Switches 5–8
(channels A, B)
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.
@6 [SPEAKERS] output connectors
These are barrier strip type speaker output connectors. For
details on how to make connections to a barrier strip, refer to
the "Connections and Setting Up" section entitled "Connect-
ing Speaker Cables" (page 18).
@7 [REMOTE] connector
This is a Euroblock 3-pin connector that allows muting/
unmuting of all channels and power-on/standby to be con-
trolled remotely. For details, refer to "[REMOTE] and
[FAULT OUTPUT] Connectors" (page 21).
@8 [FAULT OUTPUT] connector
This is a Euroblock 3-pin connector that allows an external
device to be notified when a fatal malfunction occurs in this
unit. NC and C will be shorted when the amplifier is operat-
ing normally; NO and C will be shorted when a problem
occurs (page 21).
If a problem occurs, the [PROTECTION] indicator w will
light in orange.
@9 [AC IN] connector
Connect the supplied AC power cord here. First connect the
AC power cord to the connector on the rear panel of this unit,
then plug it into an appropriate AC power outlet.
CAUTION
Before connecting or disconnecting the power cord,
make sure that the power to the unit is turned OFF.
