⚪One-touch shutdown of all receiver

Press and hold the transmitter's "S" button for 4 seconds to simultaneously turn off all receivers on the same frequency as the transmitter, making it easy to manage multiple devices efficiently. It simplifies the shutdown process, especially when multiple receivers are used at the same time.

⚪One-touch pairs transmitter and receiver

The simultaneous translation device supports the automatic pairing of transmitters and receivers. This feature simplifies the setup process and ensures a hassle-free experience for you, saving time and effort, especially in fast-paced environments such as classrooms or business events.

⚪Replaceable battery

The wireless simultaneous interpretation equipment comes with replaceable batteries to ensure continuous use. This feature is especially useful in school environments where translation kits may be used for extended periods of time. When the battery is low, it can be easily replaced, allowing uninterrupted communication without recharging.

⚪UHF frequency transmission

Language interpretation devices utilize UHF frequency transmission to ensure a smooth and reliable audio experience. The UHF frequency has a longer range and better ability to penetrate obstacles, making it ideal for use in classrooms, school events, or multilingual conferences. This feature helps minimize interference and provides clear and consistent audio transmission.

⚪Noise reduction technology

The wireless translation system uses noise reduction technology to enhance audio quality. This feature helps minimize background noise, reverberation, and other unwanted sounds, ensuring that the transmitted audio is clear and understandable. It is particularly useful in environments with high ambient noise levels, such as crowded classrooms or busy conference halls.

⚪200m working range

The translation equipment offers an operating range of 200 meters, ensuring that audio signals can be transmitted and received over considerable distances. Suitable for use in a variety of educational environments, the series allows teachers, speakers, or presenters to move freely around a classroom, auditorium, or conference venue while maintaining clear communication with the audience.

⚪50 Channel IDs

The TT116 translation system provides 50 channel IDs for flexible, interference-free communication during multilingual meetings or events. This feature allows multiple translation systems to operate simultaneously without signal interference, ensuring that each language or session has its own channel.

⚪Designated advertising space

The simultaneous interpretation equipment includes designated advertising space, allowing for customization and branding opportunities. This feature enables schools or event organizers to display relevant information, logos, or sponsor advertisements on the interpretation system to maximize visibility and create a professional and organized atmosphere.

⚪Locking buttons automatically

The wireless translation system has an automatic lockout feature that helps prevent accidental changes to settings or channel selection. This feature ensures that language translation headsets remain stable during use, minimizing interruptions and maintaining consistent communication throughout an event or classroom session.

⚪Battery life

The translation system has a long battery life of up to 10 hours for the transmitter and 13 hours for the receiver on a single charge. Long standby battery life ensures uninterrupted use throughout the day, reducing the need for frequent recharging.

⚪Audio inputs

translation devices allow simultaneous use of microphone and AUX inputs. This feature allows the simultaneous use of multiple audio sources to meet different communication needs. For example, in a classroom, a teacher can play audio from an external device while speaking into the microphone, ensuring that his or her voice and audio content are transmitted to students together.
