A full-digital networked DSP interpreter station with direct and relay translation across 63 + 1 language channels, for booth use in conferences, parliaments and broadcast halls.
Specifications as per the official Bronx datasheet (2026, Rev. A). Specifications may change without prior notice.
Any interpreter unit can be assigned as the operator station, with an internal voice link between the operator and the rest of the booth. Two interpreters can share one desk, and two booth-level operating modes (Interlock and Override) keep channels unique. A metal chassis shields against mobile-phone RF interference.
