Frequently asked questions about simultaneous interpretation equipment

Individual UHF receivers with headphones and a channel selector, soundproof portable booths, UHF transmitters and multichannel distribution racks. Every rental includes a technical operator who installs, tests and monitors the system during the event. The package can be hired with or without lingo interpreters.

Each participant gets a compact device with headphones and a channel selector. The transmitter sends the interpreted audio by UHF radio, and the participant chooses the channel for the language they want to hear. It does not depend on Wi-Fi or phones, which gives more stability in large halls.

The receivers have battery for 8 hours or more of event time, enough for a full conference day. For multi-day events, the technical team recharges and checks the devices between sessions so every morning starts with full batteries.

Receivers are available in lots of 10 to 2,000 units. For large events, sizing includes a reserve margin for swaps and possible failures, and lingo recommends the ideal quantity in the quote based on registrations and expected attendance.

It is a structure assembled in the event room, acoustically isolated, that fits 1 to 2 interpreters and measures 1.2 m × 1.2 m × 1.8 m. It connects to the venue's audio system to receive the speaker's microphone feed and lets the interpreter work without outside noise.

An ISO booth follows the international standard for acoustic isolation, ventilation and dimensions used in formal conferences. It is recommended for long, large or technically demanding events such as congresses and shareholder meetings. It includes a dedicated technician throughout the event.

The portable kit serves groups of up to 30 people, is lighter, quick to set up and does not include a technician. The ISO booth offers better isolation, more comfort for the interpreter and a technician included. For smaller meetings and site visits the kit is usually enough; for formal events, the ISO booth is safer.

It is the equipment that organizes the audio channels and extends the signal range for large events. With it, the system serves several languages at once and several rooms, with configuration and testing done before the event opens.

It is a link each participant opens on a phone to hear the interpretation through their own headphones. It requires Wi-Fi at the venue. It is a practical alternative for smaller events and can be combined with UHF receivers for those who prefer the device.

Yes. Every lingo equipment rental includes a technical operator who installs, tests and monitors the system during the event. The operator coordinates with the venue's AV team and solves any signal issue in real time, so organizers and speakers can focus on the content.

Yes, during operation. The operator arrives early for setup and tests, follows the sessions, adjusts audio levels, swaps batteries and helps participants with receiver questions. lingo states the schedule in the quote.

Before opening, the operator tests all channels, the signal at different points in the room, the booth audio and the integration with the speaker's microphone. Headphones and batteries are also checked. Any adjustment needed is made before the audience arrives.

The operator talks to the venue's audio and video team to receive a clean audio feed from the microphones, usually from a mixing desk output. The earlier that conversation happens, the fewer surprises on event day.

There are spare units and the operator swaps the device on the spot, so the participant is back on channel within moments. That is why sizing includes a margin above the registration count and the support desk sits in a visible place.

The team selects free frequencies at the venue, positions the transmitter with good line of sight and tests coverage before the event. In spaces with many wireless systems, coordination with the venue's AV team helps avoid frequency overlap.

Access for loading and setup at an agreed time, power outlets near the booth and the support desk, a contact at the venue's AV team and an audio output from the mixing desk. lingo sends this checklist with the quote so nothing is missed.

For events in São Paulo, we recommend at least 72 hours' notice. For other cities, 5 to 7 days because of freight logistics. On high-demand dates such as trade shows and congresses, the earlier you confirm, the better the availability of large lots.

For events in Greater São Paulo, yes. For other cities, round-trip freight is itemized separately in the quote, transparently. lingo serves events across Brazil.

Yes. The equipment is delivered, installed and tested by the lingo team. At the end, the same team dismantles and collects everything, with no extra work for the organizer. We agree access and loading times with the venue in advance.

From 10 participants it already makes sense to use the system. For fewer than 10 people, remote interpretation over Zoom is usually more efficient, depending on the venue and meeting format.

Yes. lingo rents and ships equipment across Brazil, with a technical operator on site. The recommended lead time is 5 to 7 days, and freight is itemized in the quote.

It can be hired with or without lingo interpreters. If the client already has their own interpreter, lingo provides only the equipment and technical operator. If you need interpreters, lingo handles everything in one quote, including vocabulary preparation for the event.

In long events, international practice is to work in pairs, rotating every 20 to 30 minutes to maintain quality. In short meetings one interpreter may be enough. lingo recommends the ideal team based on duration and content complexity.

Yes. The rental is invoiced under CNAE 77.39-0-99 by Lingo Qi Interpretações LTDA, CNPJ 53.834.741/0001-34, with a Brazilian tax invoice. This makes accounting easier for companies and bodies that require fiscal documents.

Provide the date, city, number of participants, languages and duration. The website assistant builds the quote in 60 seconds, and you can also talk to Alex on WhatsApp. The quote itemizes equipment, operator, freight and, if any, interpreters.

Yes. The same audio system can receive the output of an AI interpreter or coexist with a live captioning screen, which is useful in events with accessibility needs. lingo configures everything in parallel and the operation is unified.

UHF uses radio, passes through walls and covers large halls reliably. Infrared needs direct line of sight between transmitter and receiver. The app depends on Wi-Fi and on each participant using their own phone. For most in-person corporate events, UHF is the most robust choice.

Each language takes one channel on the transmitter and participants choose the channel on the receiver selector. You can serve several languages in parallel as long as there is a booth and an interpreter for each. lingo sizes channels and team from your event's languages.

The interpreter must hear the speaker clearly and speak without their own voice leaking into the room. Without isolation, room noise disturbs listening and the interpreter's voice mixes with the event audio. The right booth and headsets sustain quality throughout the day.

Ideally with a clear view of the stage and the slide screen, because the interpreter follows gestures, presentations and demos. It should also be near the audio point and away from noise sources such as service doors. The technical operator helps choose the best place.

Yes. Ideally the interpreter receives audio straight from the mixing desk, clean and without room echo, rather than through the hall's loudspeaker. This improves listening, reduces delay and prevents feedback. That is why integration with the venue's AV is part of the service.

Yes. In hybrid events, the interpreted audio can be delivered to people in the room by UHF and to remote participants through the video platform's language channel. lingo coordinates in-person and remote as a single operation, with the same glossary and the same team.

We do not recommend it. Speakers mix languages in the room, and ordinary Bluetooth headphones bring delay, unstable pairing and depend on each device. A dedicated receiver with a channel selector is designed for this function and avoids audio problems throughout the day.

For companies that run interpretation events occasionally, renting with an operator avoids purchase, maintenance, storage and staff training costs. You pay only for the event and get professional technical support. If you run weekly events, you can evaluate a recurring contract with lingo.

Yes. For short meetings a single interpreter and a portable kit may be enough. For longer sessions, we recommend a pair of interpreters so quality stays high throughout.

Yes. The quote is built around the schedule you give us, with setup before the first session and dismantling after the last. If the program changes, tell the operator or your lingo contact so the team can adapt the channels and the receiver count.
