Hear From Our Customers

Multilingual church services

"We purchased this system for multilingual church services, and the interpreter monitor feature was what convinced us to choose it. Having the interpreter hear the original speaker directly through the same unit made the setup much cleaner than what we had before. We no longer had to patch together extra devices just to make the workflow work. The audio has been clear, the receivers are simple enough for older attendees to use, and the range has been strong throughout the building. It feels like a much more professional setup without being difficult to manage."

--Caroline Whitmore

100-200 Person TT119 Desktop Interpretation System

Multilingual training session

"We used this system for a multilingual training session with guests from three different countries, and it made the whole event feel much more organized. What I liked most was that the receivers were simple enough for first-time users to figure out quickly. We handed them out at check-in, showed people the channel buttons once, and that was basically it. The sound stayed clear even when people moved around the venue, and the battery setup was actually practical for a full-day event. For this kind of training environment, reliability matters more than anything, and this system delivered."

--Nadège Corwin

TT117 TT118 17-Channel Portable FM Simultaneous Interpretation System

Meeting

"We used this system during a meeting, and honestly… it worked so well 😊 The sound was clear, stable, and easy to understand! even for long sessions. The earphones were also light and comfortable to wear, which really matters when people use them for hours. Overall, this is a very reliable system — no wonder it’s one of their star products 👍"

--Nicole

T130P T131P Simultaneous Interpretation System

Multilingual Guided tour

"For this system We have now tested it in a real guided visit setting, and overall the experience has been very positive. What we appreciated most was being able to keep the whole group together while different guests followed in their own language. That made the visit feel much more fluid and professional. The translation speed was good, and the users found the receivers comfortable enough even during a longer session. We also liked that the system felt more practical than relying on several separate tools.🙂"

--Alessandra Conti

TT136 Auto Translation Device for Multilingual Groups

Conference with simultaneous interpreters

"We needed a system capable of handling multiple languages simultaneously. The TT106S perfectly met our needs. Last week, we set up different channels for our three simultaneous interpreters, and attendees simply tuned their receivers to the desired channels. The entire process was interference-free, with no crosstalk between channels. The audio was clear."

--Anthony Reed

TT106S School and Conference Interpreting Device

Its long transmission range delivers clear audio even across our large sanctuary—excellent value.Setup and operation are incredibly user-friendly, so any volunteer can use it with little training.Clean, stable audio ensures every member of our congregation hears clearly."
