Features
The SX-M700 simultaneous interpretation conference system is designed to allow
delegates’ speeches to be interpreted into a maximum of six languages. Delegates
in a conference hall can thus listen to any of the interpreted languages.
The standard system supports a conference of up to 60 delegates. Connecting the
SX-E120 Expansion Unit (not supplied) allows the system to support up to 120
delegates. The SX-T100 Telephone Coupler (not supplied) allows the use of a
telephone line during a conference. By using the telephone, a person not actually in
the conference hall can also take part in the conference.
The standard system consists of the following units.
• SX-M700 Control Unit
This unit controls the simultaneous interpretation conference system.
The control unit can be mounted in a 19-inch rack.
• Chairman’s Unit/Delegate’s Unit
– SX-C700A/D700A Chairman’s Unit/Delegate’s Unit: Desktop
type. You can move these units freely in the conference room.
– SX-C750/D750 Chairman’s Unit/Delegate’s Unit: Desk-mounted type.
These units are fixed to the desks.
These units feature both a microphone and speaker.
Use the above combination of the chairman’s unit and delegate’s unit.
• SX-P700 Interpreter’s Unit
This unit, connected to the control unit, is used by a simultaneous interpreter.
• SX-T100 Telephone Coupler
This coupler is used to connect the control unit to a telephone line. Using this
coupler allows a person to take part in a conference from a remote location, even
from overseas.
In addition to the units described above, the following optional units are available.
SXA-120 Expansion Board
The board is designed to allow the expansion of the system’s functions. Installing
this board in the control unit allows the following function expansion units to be
connected.
• SX-E120 Expansion Unit
• SX-8300/S100 Microphone Control Panel
Used to enable or disable delegates’ microphones.
When multiple SX-8300 microphone control panels are used, the power interface
unit is required.
When the SX-S100 microphone control panels are used, they are connected using
only the connecting cables.
For detailed information on the power interface unit, contact your Sony dealer.
• Personal computer
For details of the SXA-120 Expansion Board, refer to the manual supplied with the
expansion board.

System Connection
This section explains how to connect the system.
Chairman’s unit/delegate’s unit and interpreter’s unit
The SX-M700 Control Unit is provided with four DELEGATE’S/CHAIRMAN’S
UNIT connectors and two INTERPRETER’S UNIT connectors. Up to 15
chairman’s/delegate’s units can be connected to each of the DELEGATE’S/
CHAIRMAN’S UNIT connectors in serial connection. The distance between the
control unit and the last chairman’s/delegate’s unit should not exceed 60 meters
(196.8 feet).
A total of seven interpreter’s units can be connected to the two INTERPRETER’S
UNIT connectors. For example, three units can be connected to one connector and
four units to the other. The distance between the control unit and the last
interpreter’s unit should not exceed 60 meters (196.8 feet).
Notes
• Be sure to turn off the power of any units before attempting connection or
disconnection.
• The SX-C100A/C150/D100A/D150 Chairman’s Unit/Delegate’s Unit, designed
for the conference system, can be connected to configure this simultaneous
interpretation system. However, interpreted languages cannot be heard via these
SX-C100A/C150/D100A/D150 units. Also, after the system power is turned on,
the microphone indicator and MIC ON/OFF buttons of the chairman’s unit and
delegate’s unit continue to blink for about 3 seconds to inform that the
SX-C100A/C150/D100A/D150 units for conference system have been connected
to the simultaneous interpretation system.
• If you turn on the system power before connecting the chairman’s unit/delegate’s
unit, the microphone indicators and MIC ON/OFF buttons continue to blink and
these units cannot be controlled by the control unit. In such a case, turn the power
off, then back on again.
• When using the INTERPRETER’S UNIT connectors (20-pin multi-connector)
and DELEGATE’S/CHAIRMAN’S UNIT connectors (20-pin multi-connector)
of the control unit, attach the dust caps removed from the 20-pin multi-
connectors on the control unit to the 20-pin multi-connectors on the last unit
connected.
If the 20-pin multi-connector has no dust cap, keep it away from metal tools,
such as screwdrivers to prevent the connectors being inadvertently shorted.
• Do not set the POWER switch of the SX-M700 to ON again promptly after the
POWER switch is set to OFF. If you do so, the power of the SX-M700 may not
be turned on, or the software built in the SX-M700 may not start. Be sure set the
POWER switch to ON again 30 seconds or more after the power is turned off.

Taking Part in a Conference via the Telephone
A person can take part in a conference from a remote location by using the
SX-T100 Telephone Coupler .
1 Rotate the TELEPHONE COUPLER channel selector on the control unit to the
channel corresponding to the other party’s language.
2 Set the POWER ON/OFF switch of the telephone coupler to ON.
3 Set up a telephone connection with the party who will take part in the
conference.
4 Place the handset on the telephone coupler after the other party answers the
phone. The handset catch part is movable. Adjust the coupler to the handset
size and secure the handset with the handset-securing tape.
The called person can now take part in the conference. The person’s speech is
fed to the conference hall as the original signal. The interpreted language
selected by the TELEPHONE COUPLER channel selector is sent to the other
party via the telephone line.
Notes
• Orient the handset correctly.
• If the handset is not adjusted to the coupler, the satisfactory communication may
not be possible.

Troubleshooting Guide
Should a problem arise in your system, check the system while referring to the
instructions in the table below. If the system continues to malfunction after
applying the following checks and remedies, contact your nearest Sony dealer.
The system indicates the problem by lighting the microphone indicator and MIC
ON/OFF button of chairman’s/delegate’s units.
The indicator and button
blink for a few seconds
when the POWER switch
of the control unit is set
to ON.
The chairman’s unit/
delegate’s units for a
simultaneous
interpretation conference
system, SX-C700A/
D700A/C750/D750, and
those for a conference
system, SX-C100A/
D100A/C150/D150, have
been connected.
To configure the simultaneous conference system, use only
SX-C700A/D700A/C750/D750 units.
The SX-C100A/D100A/C150/D150 can be used. However,
the simultaneous interpretation cannot be heard.
Possible cause Remedies
Lighting of the
microphone indicator
and MIC ON/OFF button
of the chairman’s unit/
delegate’s unit
The indicator and button
of the chairman’s/
delegate’s units continue
to blink, after the power
switch of the control unit
is set to ON.
The units whose
indicator and button are
blinking cannot be
controlled by the control
unit and cannot be used
in this system.
• When the indicator and button of units subsequent to the
16th unit of the units connected to one DELEGATE’S/
CHAIRMAN’S connector of the control unit blink:
– More than 16 units cannot be connected to one
DELEGATE’S/CHAIRMAN’S connector in series.
Disconnect the 16th unit and subsequent units.
• Even though the number of connected units is less than
16, the indicators of some of the connected units blink:
– The first unit whose indicator and button are blinking
may be defective, or the connecting cable may be
broken.
Disconnect the first unit of those whose indicator and
button are blinking. When the indicator and button of the
subsequent units stop blinking and go out, it indicates
that the disconnected unit was defective. Remove it from
the system or replace it with a functioning unit.
When the indicator and button continue to blink even
after removing the first unit, the connecting cable is
probably broken. Replace the connecting cable linking
the first unit whose indicator and button are blinking and
the unit immediately prior to that unit.
• Even though the number of connected units is less than
16, the indicator and button of some of the connected units
blink:
– The unit whose indicator and button blink is defective.
Disconnect it from the system or replace it with a
functioning unit.
Briefly turn the power off, then back on again.
If the unit subsequently operates normally, communication is
resumed.
If this problem occurs frequently, contact your nearest Sony
dealer.
If the indicator and button continue to blink just after the
power is turned on again, a problem described above may
have occurred. Proceed as described above.
A communication error
has occurred.
After the unit has been
operated for a while after
the power is turned on,
the unit’s indicator and
button start blinking and
do not go out, even after
a few seconds.

Possible cause Remedies
The earphone may be
disconnected. Insert the earphone plug into the earphone jack surely.
The volume of the
earphone cannot be
adjusted by using the
VOL control.
The earphone may be
disconnected. Insert the earphone plug into the earphone jack surely.
Lighting of the
microphone indicator
and MIC ON/OFF button
of the chairman’s unit/
delegate’s unit
The channel of the
language to be
monitored cannot be
selected by the CH
selector.
• The mode is that
where the number of
speakers is limited.
• The PRIORITY button
is held down by the
chairman.
• Wait until the speaker finishes speaking. Press the MIC
ON/OFF button again.
• Wait until the chairman releases the PRIORITY button.
The indicator and button
blink and the microphone
is disabled even if the
MIC ON/OFF button is
pressed.
