Desktop all-in-one transmitter with UHF wireless transmission. Just connect the power cable to get started, reducing cable clutter and making setup faster and easier.
The system supports 19 channels in the EU version and 50 channels in the US version, making it easier to accommodate up to 4–8 interpreters for multilingual events.
Uses UHF wireless technology for stable transmission and strong anti-interference performance, helping maintain clear audio in complex environments.
Delivers long-range wireless coverage up to 250 m / 820 ft in open areas, suitable for churches, auditoriums, meeting rooms, and tours.
Built-in DSP noise reduction helps reduce background noise and improve speech clarity for interpretation, training, and live presentations.
When one person needs to speak and many people need to listen at the same time, clear delivery matters just as much as the equipment itself. The Retekess T130T transmitter and T131T receiver work together as a practical solution for simultaneous interpretation, international meetings, churches, classroom training, and business presentations. With one-key channel sync, receivers within 6 meters can pair automatically in CHS mode in about 10 seconds, helping speed up setup for larger events. As desktop simultaneous interpretation equipment, the system helps simplify deployment, improve listening clarity, and keep events running more smoothly.
1. Connect the speaker's audio source to the T130T via XLR or AUX input.
2. The interpreter monitors the original speech through headphones connected to the T130T.
3. The interpreter speaks into the microphone, and the T130T broadcasts the translated audio on a selected channel.
4. Additional interpreters can use separate T130T transmitters to provide other language channels simultaneously.
5. Attendees select their preferred channel and listen to the interpretation in real time using T131T devices.
6. You can choose whether the original floor audio is monitored only by interpreters or shared with attendees, providing greater flexibility for different event setups.
The EU version supports 19 channels and the US version supports 50 channels, making it easier to manage multi-language interpretation and multiple teams at the same time. Accommodating up to 4–8 interpreters, the system is a practical choice for large meetings, conferences, and more complex event setups.
In larger spaces, unstable audio can make it harder for people to stay focused. Built as a professional UHF interpretation system, the T130T T131T delivers up to 820 ft of range in open areas and helps maintain steady listening even when the group is spread out. It is a practical fit for meeting rooms, auditoriums, churches, and tour routes.
Traditional interpretation systems often come with extra cabling, which can slow down setup and cleanup. The T130T uses UHF wireless transmission and only needs power to get started, helping reduce cable clutter in meeting rooms, churches, and training spaces. Paired with a desktop gooseneck microphone, it keeps the setup neat and easy to manage while making on-site deployment more efficient.
In churches, tours, or crowded spaces, background noise can easily get in the way of clear speech. The transmitter uses built-in DSP noise reduction to help reduce ambient noise and make voices easier to hear. That makes interpretation, guided speaking, and live presentations easier to follow.
When you need to prepare multiple receivers, manual tuning can slow everything down. The T131T receiver supports automatic channel search, and the system also supports one-key channel sync in CHS mode, allowing receivers within 6 meters to pair automatically in around 10 seconds after setup begins. That helps speed up distribution for meetings, worship services, training sessions, and larger group events.
Different events often rely on different audio sources, and connection issues can quickly interrupt the flow. The T130T supports Bluetooth 5.0, USB, TF card playback, RCA LINE IN, XLR, 1/4 in, and 3.5 mm connections, making it easy to work with phones, computers, conference systems, mixers, and different microphones. It also supports Bluetooth, USB, and TF card playback for on-site voice reinforcement and audio playback, giving you more flexibility from one system.
The lighter the receiver, the easier it is for listeners to wear comfortably for longer periods. The T131T receiver weighs just 1.06 oz and comes with an earphone and lanyard for easy use and distribution. That makes it a better fit for meetings, worship services, and guided tours.
Frequent charging can make device management harder than it needs to be. The T131T receiver runs for about 40 hours and recharges in around 3 hours, making it well suited for long meetings, full-day training, and extended tours. That means fewer interruptions and easier planning throughout the day.
When a new system does not work with what you already have, upgrade costs can rise quickly. The T130T is compatible with T131T, T131U, and T131R receivers, and it can also work with select existing accessories such as charging cases. That makes expansion easier and helps protect your previous investment.
If a system only works well in one setting, its long-term value can be limited. The T130T T131T works well for worship translation, guided tours, training, and meetings. That gives you one system that fits more everyday use cases.
Mute the Mic Without Stopping Background Audio
Press and hold MUTE for 2 seconds to mute the microphone while keeping LINE IN audio playing. This lets you pause speaking without interrupting the atmosphere.
Power Off All Receivers at Once
In lock mode, press and hold CH+ for 5 seconds to turn off all receivers at once. That makes post-event cleanup faster and easier.
Auto Lock for More Stable Operation
The transmitter locks automatically after 10 seconds of no operation, helping prevent accidental changes to the channel or volume. This keeps the system more stable during live use.
Auto Screen Off and Auto Power Off
The receiver screen turns off after 1 minute of no operation, and the unit powers off automatically after 20 minutes without a signal. This helps save battery and simplifies post-event management.
Recommended starting point: 1 transmitter + 10 receivers
If this is your first purchase or your audience size is within a typical range, this package is an easy place to start. It works well for small meetings, church worship, classroom teaching, staff training, and small guided groups.
If your audience grows later, you can continue adding more receivers. As long as the devices are compatible and use the same channel, the system can be expanded easily.
The T130T is more than a single device. It is a practical solution built for real everyday use.
