2. GENERAL DESCRIPTION
The TOA TS-910 Series conference system permits both its infrared wireless system unit and wired system unit
via CAT-5 LAN cable connections to be used in combination.
The wired Chairman and Delegate units (collectively referred to as “Conference units”) are connected to the
Central unit via the wired Expansion unit and Bridge unit.
The Infrared Conference units provide wireless communication via the Infrared Transmitter/Receiver unit
connected to the Central unit. Since wiring to the individual conference units is not required, they can be easily
installed in freely versatile configurations.
The Central unit is used to perform system function settings, status display, etc.
3. FEATURES
• ThenumberofConferenceunitstobeusedcanbefreelyselecteddependingonthenumberofparticipants.
A total of up to 192 Conference units can be installed in a single system.
• WiredConferenceunitscanbeusedinanycombinationwithInfraredConferenceunits.
• ASimultaneousSpeakerNumberRestrictorfunctionreducesthechanceofchaosandconfusionthatcan
result from too many speakers trying to talk simultaneously.
• ASpeechPrioritySelectorfunction permits selection of operating priority (first-in-first-out or last-in-first-out)
when the speech key is pressed.
• Ifanymicrophonesarenotmanuallyturnedoffafterspeaking,thesystem’sMic-Offfunctionautomatically
switches them off if not in use for approximately 30 seconds.
• A built-in Feedback Suppression Function (FBS) ensures more efficient reduction of acoustic feedback*.
When Conference units are in use, their monitor speakers are automatically turned off, eliminating concerns
about acoustic feedback.
• Dependingoninstallationrequirements,wiredmicrophones,musicplayingequipmentandotherdevicescan
be freely combined and used within the system.
• RecordingequipmentcanbeeasilyconnectedtotheCentralunit,makingitidealforpreparingconference
minutes.
*Acousticfeedback:The squeal or howl of a sound loop created when speaker output is picked up by a
microphone, amplified by an amplifier and further output from the speaker again.

5.2. Infrared Chairman Units TS-901 and TS-801
[TS-901 Top]
1. Monitor speaker
Speech signals from other Conference units and
other audio signals from the Central unit are output
from this speaker. (Refer to the table below.)
Model Output signal
TS-901 Base language or Translation language
Note: Switchable by the Monitor selector
switch (17).
TS-801 Base language
Use the right-side Monitor Volume Control (16) to
adjust the volume. No sound is output from the
speaker of the unit in use while speaking.
2. Microphone
Use either the TS-903 (Standard) or TS-904 (Long)
dedicated microphone.
3. Microphone in-use indicator
Lights when the microphone is turned on (for
speech)andasheswhenthebatterylevelislow.
4. Infrared emitter/detector
The device used to transmit and receive infrared
communication signals is built inside this panel.
Note
Never place any object that could block infrared
signal access to this part of the unit, as this would
prevent the unit from transmitting or receiving its
required infrared signal.
5. Voting keys (TS-901 only)
Use these keys to start, end, and cast voting. The
voting status indicator is provided on each key.
6. Speech indicator
Remains lit while the microphone is in use (during
speech).Theindicatorasheswhentheunitisout
of the communications service area.
