Bidule — Mobile Simultaneous
No booths. No fixed equipment. Full professionalism.
The bidule is a simultaneous interpretation technique designed for those who move. Factory visits, plant tours, workshops in unconventional spaces, small groups in environments where setting up a booth would be impractical or simply disproportionate.
The interpreter is free to follow the group, without being tied to a fixed station. The audience listens in real time. All wireless, all battery-powered, zero cables.
Our system — a step ahead of the standard
In traditional bidule, the interpreter listens to the speaker directly with their own ears and translates into the microphone. It works, but it has its limits: ambient noise, distance, difficult acoustics.
The Verso system adds an element that changes everything: the interpreter receives the speaker's audio through headphones, via a dedicated pocket-sized mobile kit. Clean listening, controlled level, independent of the room's acoustics. The result is professional interpretation quality even in complex environments.
How it works — the components
mic Speaker side — three options
Plug-on transmitter
Connects directly to the venue's existing audio system via AUX or MAIN output. It's the ideal choice when the venue already has a mixer and installed audio system — no additional microphone, the signal is taken directly from the console.
Handheld transmitter
The classic wireless microphone to pass from hand to hand. Ideal when there are multiple speakers alternating dynamically — round tables, Q&A sessions, group discussions.
Bodypack transmitter with clip microphone
Clips onto the speaker's jacket or belt and leaves hands completely free. The natural choice when there's a single speaker who needs to move, gesture or handle materials during the presentation.

A pocket-sized device that receives the speaker's audio signal and plays it through headphones with professional quality. The interpreter listens to the floor cleanly and controlled, regardless of ambient noise or physical distance from the speaker. Transmits their voice on a single wireless channel to the audience receivers. Battery-powered, pocket-sized, requires no external power.
groups Audience side
Compact wireless receivers with disposable stereo earpieces. The audience listens to the translation in real time, with the same simplicity as a tour guide system — but with professional event quality and reliability.
When it's the right choice
The bidule is not a simplified version of booth interpretation — it's a different technique, designed for different contexts. It's the natural choice for:
Manufacturing plant visits, trade fairs and showrooms
Guided tours in industrial or museum environments
Workshops in unequipped spaces
Small groups up to 30-40 people in informal settings
For formal events with more than one language and a large audience, booth interpretation or our digital solutions MRSI and RSI remain more suitable. If you have doubts, tell us about your event — we'll tell you in ten minutes which solution is right.

smartphone More languages, relay included — no additional hardware
With the Converso WebApp and Soft Console on a smartphone or tablet, interpreters work on the move exactly as in a virtual booth. Unlike the physical bidule, this setup supports multiple simultaneous languages and relay between interpreters. Ideal when the group is multilingual and operational simplicity remains a priority.

With MRSI Mobile, a single Converso technician brings a compact RSI Bridge, bonding connectivity and stabilized video to the location. Interpreters work remotely from the Milan Hub. The result: 11 languages among the machinery of an industrial plant, with conference-hall quality. We've done it. It works.
