2. GENERAL DESCRIPTION
The TOA TS-910 Series conference system permits wired system unit via CAT-5 LAN cable connections to be
used in combination.
The Chairman and Delegate units (collectively referred to as “Conference units”) are connected to the Central
unit via the Expansion unit and Bridge unit.
A total of up to 192 Conference units can be connected to the Central unit of each system.
The Expansion unit and Bridge unit are necessary for connection of the Conference units. (Refer to
p. 22.)
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.
• 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.
[Conference unit]
• Both 900 Series Conference units equipped with Voting and base/translation language selection functions
and 800 Series units designed primarily for speaking and monitoring can be freely used. In the case of the
800 Series Conference units, they can monitor the base language only.
• Each 900 Series and 800 Series feature a selection of both Conference units.
• Chairman units feature a Priority Speech Key Operation function that allows the Chairman unit to take speech
priority over the Delegate units with the simple press of a button.
• Conference unit microphones are attached via XLR connectors that permit easy detachment for more space-
saving convenience in storage.
• Two types of Conference unit microphones are made available and freely interchangeable: Standard type
and Long type.
• Connections between wired Conference units and the Expansion unit (or Bridge unit) can be made using a
single CAT-5 LAN cable, facilitating installation and construction work.
• A total of up to 24 Conference units can be connected per TS-918 Expansion unit.
• Up to 8 TS-918 Expansion units can be installed.
• Two types of Bridge units are available: single-Conference unit connection type and 4-Conference unit
connection type, either of which is freely selectable depending on installation conditions.
