1
POWER indicator
Lights when the power of the control unit of the
conference system is turned on.
2
AC IN (AC power input) connector
Connect to an AC power source using the supplied AC
power cord.
3
LINE IN (input) connector (D-sub 15-pin)
Inputs the audio signals of the original speech and six
channel interpreted languages and 24 V DC power.
4
LINE OUT (output) connector (D-sub 15-pin)
Outputs the buffer audio signals of the original speech
and six channel interpreted languages and 24 V DC
power for the wired monitor unit. Connect to another
SXA-J750.
5
Outlet for SXA-J751 connecting cable
Outlet for the cable connecting to the SXA-J751. The
connecting cable is soldered to the TM1 and TM2 pins
of the outlet connector. The SXA-J751 Joint Boxes are
connected successively by using the cabe with
connectors at both sides. Up to 60 SX-H750 can be
connected to one SXA-J751. Decide the number of the
SXA-J751 according to the layout of the wired
monitor units. Up to two SX-H750 can be connected to
one SXA-J751.

Notes
• To connect the wired monitor units to the conference
system, the SXA-J750 and SXA-J751 (neither is
supplied) are required.
• The audio signal input to the SXA-J750 is high
impedance. Short-circuit the input pins of unused
channels to put them at low impedance.
• Up to 60 SX-H750 can be connected to one SXA-
J750, and two SX-H750 can be connected to one
SXA-J751.
