Description

 TT129 3 Transmitters Full-Duplex Intercom for Small Team

The TT129 Full-Duplex Three-Transmitter Solution is engineered for deep collaboration within 3-person teams. It breaks the "talk-and-wait" limitation of traditional intercoms, delivering a full-duplex communication experience where all three members can speak and listen simultaneously, making team interaction as natural and fluid as a face-to-face conversation.

Core Advantage: Triple Full-Duplex Intercom System

  • True Three-Person Full-Duplex

All three members can speak and listen at the same time, with no need to wait for others to finish. Enables seamless communication flow and more effective brainstorming, significantly boosting team collaboration efficiency.

  • Independent Communication Units

Each transmitter is a complete, standalone communication unit. Auxiliary transmitters(S-transmitter, R-transmitter) do not require an additional receiver to hear other speakers, simplifying setup and enabling more direct collaboration.

  • Complete Conversation Awareness

Each member can hear their own voice in real-time through the headset (side-tone monitoring) and can independently adjust the listening volume. This ensures a comfortable, natural speaking state and guarantees clearly transmitted content.

Ensuring the Full-Duplex Experience

  • Intelligent Noise Cancellation for Clarity

Environmental noise can be amplified when three people speak simultaneously. The TT129 supports adjustable noise cancellation levels, effectively filtering background noise to ensure the received audio remains clear speech, even in complex environments.

  • Independent Control, Uninterrupted Operation

Each member can independently mute or unmute their own microphone and separately adjust their microphone gain, providing flexibility for different speaking scenarios and personal preferences.

  • Stable Connection & Long-Lasting Battery

100m Wireless Range: Stable transmission up to 100 meters in open areas between main and auxiliary transmitters, ensuring reliable communication even when the team is on the move.

Ultra-Long Battery Life: The transmitter operates for up to 20 hours. The receiver operates for up to 120 hours, meeting the demands of multi-day, high-intensity use.
