Problem-Solution Description

In a conference meeting, the chairman needs to speak with authority, control the discussion, and stop interruptions without manually asking delegates to mute. Audio feedback and uncontrolled mic activation are common problems.

The TOA TS-781 solves this with two smart controls:

Take Instant Control: The priority button overrides all active delegate units (TS-782), cuts off their microphones, and plays a single-tone chime to alert everyone that the chairman is speaking.
Speak Without Feedback: The speech button activates the microphone while automatically turning off the built-in speaker, preventing feedback loops completely.
Monitor When Silent: When the speech button is OFF, the speaker turns back on so the chairman can hear other delegates clearly.
Private Listening: The headphone output with independent volume allows the chairman to monitor audio privately when needed.

Quick Review: Is It Worth Buying?

Yes, if you need chairman-level control in a TOA conference system.

The TS-781 is essentially the TS-782 with one critical upgrade: the priority button. This makes it essential for any meeting where one person must have the final say. The anti-feedback design is intelligent, the built-in speaker is practical for monitoring, and the compact size keeps the table clean.

Keep in mind: this unit requires the TOA TS-780 Central Unit to operate, and the microphone is purchased separately (choose TS-773 standard or TS-774 long based on your table size).

FAQs

What is the price of TOA TS-781 in Bangladesh?
Please contact Expert Technologies BD for the latest and actual price.

What is the difference between TOA TS-781 and TS-782?
The TS-781 is a Chairman Unit with a priority button that can override delegate microphones and activate a chime. The TS-782 is a Delegate Unit without priority control.

Does the TOA TS-781 come with a microphone?
No, the microphone is sold separately. You can choose the TS-773 (standard) or TS-774 (long) type.

What does the priority button do?
When pressed, it takes precedence over all delegate units, cuts off their active microphones, and plays a single-tone chime to signal that the chairman is speaking.

Why does the speaker turn off when the microphone is on?
This is an anti-feedback design. When the speech button is ON, the speaker automatically disables to prevent audio feedback during speech.

Can I use the TOA TS-781 without a central unit?
No. It must be connected to the TOA TS-780 Central Unit to receive power and function properly.
