In addition, these headsets are suitable for people with hearing impairment in one ear, meeting their specific needs.

Two-color LED display

The TT125 audio tour guide features a two-color LED display measuring 24x13mm. The display shows the status of power, channel, and signal, providing more intuitive information to the user.

One-touch mute

The transmitter supports a one-touch mute function, which allows the guide to temporarily mute the microphone without turning off the transmitter. This is useful in situations where a guide needs to have a private conversation or with a break to quickly pause the audio transmission.

One-touch automatic channel synchronization

The tour guide audio system offers one-touch pairing, enabling multiple receivers to be paired with a transmitter in a short period of time. This saves valuable time and improves the overall efficiency of setting up and operating the equipment for the guide.

Supports AUX and MIC inputs

The transmitter's MIC interface can also be connected to audio devices, enabling guides to supplement their narration with pre-recorded audio or background music, thus providing a more engaging tour experience. (Note: AUX input and MIC input cannot be used at the same time)
