Tour guide translation system enables interpreters to provide accurate and seamless conference interpretation services.

- Stereo transmission

The conference interpreting equipment supports the transmission of audio signals in stereo, allowing listeners to experience the translated content in high sound quality, creating an immersive meeting experience.


- One-touch mute transmitter

Translators can mute the transmitter immediately by pressing the mute button, while the screen displays the mute icon, and pressing the mute button again to release the mute. This function can temporarily suspend sound transmission when there is background noise or when the translator needs a moment of silence during translation.

- AA battery powered

Language translation devices require 2 AA batteries for power. This makes it easy to replace the batteries and ensures that the device can be used for long periods of time without frequent recharging. This battery-powered design also enhances the portability and flexibility of the device.


- Flexible expansion

The transmitter can be used with any number of receiver devices. This allows for easy scalability and adaptability, as the number of translators and their corresponding receivers can be adjusted to meet the needs of the meeting. This also ensures that the translation equipment can accommodate any number of languages or participants.

- 17 channels available

The tour guide translation system has 17 channels, allowing up to 8 groups of interpreters to operate simultaneously from the same location, without interference. This is critical for conference environments where multiple languages are spoken and translated simultaneously. The ability to operate 8 groups simultaneously also ensures efficient and smooth translation services.


- One-touch lockout

The translation device is equipped with a lock button. Toggling the "power switch" to the "lock" position locks the key to prevent accidental changes during a meeting. This ensures stability and consistency in the translation process. The volume adjustment buttons are not locked and can still be adjusted.

- Easy to use

9 levels of adjustable hearing ensure that users with different hearing abilities or preferences can listen comfortably.

TT117 transmitter and TT118 receiver are pocket-sized and lightweight, making them easy to carry and transport.

The translation system's LCD backlit display shows information such as channel, battery level, and volume.

The battery level display allows users to monitor the power status of the device, ensuring that the battery is not drained during critical translation tasks.

The easy-to-operate interface and controls make it user-friendly and do not require experience or skill to use.

- Communication range

Conference interpreting equipment has an operating range of approximately 80 meters (262 feet). This ensures that even in large conference venues, the translation signal can reach the receiver(audience) without loss of quality or interruption. This extensive coverage allows translators to work from all parts of the venue, providing greater convenience and flexibility.

- MIC input and AUX input

The Translator Transmitter is equipped with a 3.5mm connector that supports microphone (MIC) input and auxiliary (AUX) input. This allows translators to connect a microphone to the transmitter for direct voice translation. In addition, the AUX input can be used to connect an external audio source, such as a computer, cell phone, or other audio player, for playing back pre-recorded translations or other audio content.
