Features
The infrared conference system is designed to convert
audio signals into infrared optical signals, which are
transmitted through an infrared radiator to receivers in
the conference hall. Combined with a simultaneous
interpretation system, the system can be applied to the
likes of a large-sized international symposium, or
panel discussions featuring speakers from many
countries. The transmitter is equipped with 13 (SX-
1130A) or seven (SX-1070A) connectors to input a
maximum of 12 or six interpreted languages, plus the
original language. Since the system uses infrared
rays, confidential or secret material cannot leak
outside the conference hall.
The system is composed of the following units.
• SX-1070A/1130A Infrared Transmitter
– This unit passes the signals via the 75-ohm
coaxial cable, to the infrared radiators placed a
maximum of 200 meters (656 feet) from the
transmitter.
– Signal transmission is based on the PPM (Pulse
Position Modulation) method so that the
transmitting range is not affected by the number
of channels in use.
– You can connect up to five infrared radiators in
series to each DISTRIBUTOR connector of the
infrared transmitter. Thus you can connect a
maximum of 10 infrared radiators to one infrared
transmitter.
– You can mount the unit in a 19-inch rack using
rack mount fixings (not supplied).
• SX-9131A/9134 Infrared Radiator
– The unit receives audio signals which it converts
to infrared that is then picked up by receivers in
the conference hall.
– The unit is compact and lightweight yet offers
high-level output.
• SX-2130 Infrared Receiver
– The receiver picks up the infrared output by the
radiator.
– The unit uses a newly developed rechargeable
lithium ion battery. With a fully-charged lithium
ion battery, the receiver operates continuously for
22 hours.
– You can hook the receiver onto a pocket. The
unit can also be hung around the neck using the
supplied strap.
• SXA-75 Charger
– The SXA-75 Charger is designed to recharge the
infrared receivers’ built-in lithium ion batteries.
– You can recharge 50 receivers at one time.
Recharging takes about 5 hours.
– To recharge 17 or fewer receivers takes about 2
hours.
– The three BATTERY CHECK indicators allow
you to check the current charge level of the
batteries.
