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-M100 Control Unit   This unit controls the conference system.   The control unit can be mounted in a 19-inch rack.   • Chairman’s Unit/Delegate’s Unit   – SX-C100A/SX-D100A Chairman’s Unit/Delegate’s Unit: Desktop   type. You can move these units freely in the conference room.   – SX-C150/SX-D150 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-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/SX-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.   4 Download from Www.Somanuals.com.

The   microphone operation depends on the setting of the   MIC ON/OFF button 8.   For details, see the explanation of the MIC ON/OFF   button 8.   8 MIC ON/OFF button and indicator   SX-C100A/SX-C150: Pressing this button turns   the microphone on. The MIC ON/OFF button   indicator and microphone indicator 2light.   Pressing this button again turns the microphone   off. The indicators go out.   SX-D100A/SX-D150: When the MIC LIMIT ON/   OFF button on the control unit is set to OFF   (the MIC LIMIT ON/OFF button indicator does   not light), pressing this button turns the   microphone on. The MIC ON/OFF button   indicator and microphone indicator 2light. In   this mode, since the number of speakers is not   limited, the microphones of all the delegate’s   units are enabled.   3 Speaker   The sound is heard through this speaker when the   microphone is not being used and when an   earphone is not plugged into the earphone jack.   The speaker’s volume is adjusted from the   SX-M100 Control Unit. To prevent howling,   nothing is output from the speaker when the   microphone of the chairman’s/delegate’s unit is   enabled. Also at the same time, the speaker volume   of the units on either sides of the unit is   automatically reduced.   4 VOL (volume) control   Adjusts the volume of the earphone. Even if the   VOLUME control is turned fully   counterclockwise, the earphone volume cannot be   turned off. (The speaker volume is not affected by   this control.)   When the MIC LIMIT ON/OFF button on the   control unit is set to ON (the MIC LIMIT ON/   OFF button indicator is lit), the number of   speakers is limited. Thus, when the MIC ON/   OFF buttons of more than six delegate’s units   are pressed at the same time, the indicator of   the sixth delegate’s unit blinks (for about 3   seconds) to tell the user that the microphone   cannot be enabled since the number of units   whose MIC ON/OFF button is pressed exceeds   six.   5 Cable with 20-pin multi-connector (for   the SX-D100A/SX-C100A only)   Connect to the DELEGATE’S/CHAIRMAN’S   UNIT connector of the SX-M100 Control Unit,   SX-E120 Expansion Board (not supplied) or the   output connector of another chairman’s unit/   delegate’s unit.   11   Download from Www.Somanuals.com.

The distance between the control unit   and the last chairman’s/delegate’s unit should not   exceed 60 meters (196.8 feet).   specified in “Specifications” section.   • Do not drop or place heavy objects on the power   cord. If the power cord is damaged, turn off the   power immediately. It is dangerous to use the   unit with a damaged power cord.   • Disconnect the power cord from the AC outlet by   grasping the plug, not by pulling the cord.   Keep foreign objects out of the cabinet   Dropping flammable or metal objects into the   cabinet, or spilling liquids onto the cabinet can   lead to accidents.   Notes   • Be sure to turn off the power of any units before   attempting connection or disconnection.   • The desktop type SX-C100A/D100A and the   desk-mounted SX-C150/D150 are used with this   system.   It is not recommended to mix both combinations.   • When the SX-C100A/D100A is used, the SX-   C700A/C750/D700A/D750 Chairman’s Unit/   Delegate’s Unit, designed for the simultaneous   interpretation conference system, can be   connected to configure this conference system.   However, 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-C700A/D700A units for   simultaneous interpretation conference system   have been connected to the conference 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 DELEGATE’S/CHAIRMAN’S   UNIT connectors of the SX-M100 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   In case of malfunctions   If you notice any unusual sound, smell or smoke,   turn off the power immediately, disconnect the   power supply and contact your Sony dealer.   Cleaning   Clean the cabinet and panels by wiping with a soft,   dry cloth. For severe stains, moisten the cloth with   a small amount of neutral solvent, and finish by   wiping with a dry cloth. Do not use alcohol,   benzine, thinner or volatile liquids, as these may   discolor or damage the cabinet surface.   screwdrivers to prevent the connector being   inadvertently shorted.   14   Download from Www.Somanuals.com.
