Key takeaway
Simultaneous Interpretation Systems for Chennai’s biggest events
Interpretation is a standards-driven discipline, and the standards exist because interpreters working in bad conditions make mistakes. Mobile booths are built to ISO 4043, which specifies a working space of roughly 1.6 by 1.6 by 2.0 metres for two interpreters, sound insulation from the floor and from adjacent booths, forced ventilation with a defined air change rate that is quiet enough not to intrude on the microphone, and a full-width front window with unobstructed sight of the speaker, the screen and the delegates. Permanently installed booths follow ISO 2603, and the equipment itself — consoles, headphones, microphones — follows ISO 20109. Where a client asks us to put interpreters in a curtained corner, we decline, because sightline and sound isolation are not optional extras.
Booth siting is the whole design problem: interpreters need direct sight of speaker and screen, while infrared radiators need line of sight to every seat around pillars and balconies. In Chennai that plays out at venues like Chennai Trade Centre, Nehru Indoor Stadium, ITC Grand Chola, and across OMR, Guindy, Anna Nagar, T Nagar.
Distribution to delegates is almost always infrared on a Bosch Integrus or equivalent system, for one reason that matters more than audio quality: infrared does not pass through walls, so a confidential session cannot be received from the corridor. Radiators are placed to cover the seating area with line of sight to every receiver, and coverage is calculated from radiator power against the room area, with careful attention to shadowing behind pillars, under balconies and in deep seating. Channel planning allocates one channel per target language plus the floor language, and the carrier frequencies are chosen to avoid interference from certain LED and plasma lighting that radiates in the infrared band.

Equipment we carry
Why Chennai chooses Prime AV
- Crews and trucks positioned for fast load-in at Kalaivanar Arangam and venues in T Nagar and ECR.
- Scripts and slides go to interpreters at T-2 weeks, and the chair is briefed to remind speakers that they are being interpreted, which is the single most effective intervention available.
- Per-channel recording of each language output where required
- Working knowledge of Tamil Nadu venue rules, power sanctions and permission timelines.

Local conditions
Producing interpretation equipment in Chennai
Weather & the rig
Interpretation booths are sealed, ventilated boxes holding two people for hours, so ambient heat and the venue's cooling capacity directly affect whether the ISO ventilation requirement can actually be met. Chennai's problem is humid salt rather than heat alone. Relative humidity stays between 75% and 85% most of the year with sea air reaching well inland, so connector pins corrode, long copper multicore runs oxidise at the terminations and anything stored uncovered overnight comes back damp. Then the Agni Nakshatram weeks in May and June combine 40°C with that humidity, which is far harder on amplifier and dimmer racks than dry 44°C in Rajasthan — forced-air cooling is a specification item, not an upgrade. The north-east monsoon in late in the year leaves standing water, so distro and cable crossings go up on pallets as a matter of course. Oct–Dec north-east monsoon, which is the inverse of the rest of India and is exactly why the local season reads Nov–Feb and the genuinely dependable outdoor window does not open until January.
Power & redundancy
Booths, consoles, radiators and a receiver charging operation all need clean uninterrupted supply, and the charging bank is a surprisingly large overnight load on a thousand-delegate event. TANGEDCO supply inside the city is reasonable, but the industrial belts at Sriperumbudur and Oragadam run with routine voltage sag under plant load, so a dealer event inside a factory needs a servo stabiliser ahead of the dimmer racks and LED processing rather than just a changeover. Outdoor and lawn work is fully generated with acoustic enclosures to satisfy TNPCB.
Permits & noise rules
Multilateral and government sessions bring security clearance for crew, controlled access to the booths and recording consent requirements rather than conventional event permissions. Greater Chennai Corporation grants ground and temporary-structure permission, the Greater Chennai Police Commissioner's office licenses public performance and loudspeaker use, and TNPCB's noise standards apply alongside the 10pm cut-off, which is enforced firmly in the residential heart of Mylapore, T Nagar and Alwarpet. Drone restriction around Meenambakkam covers Nandambakkam, Guindy and much of the south-west, so aerial coverage of a Trade Centre event is generally not available.
Load-in & access
Flight-cased booth panels are bulky and need a clear path to a position with sightline to the stage, and receiver distribution has to happen at the entry point before delegates disperse. Heavy vehicles are kept off the arterials in daylight and the port-bound corridor congests unpredictably, so hotel load-ins sit in an 11pm to 7am window. Nandambakkam and the airport-side venues are easy. The difficult work is in T Nagar and Mylapore, where a kerbside drop with police present and a hand-carry down a lane is the only option, and the lane width sets the crew number.
Season & booking
The Margazhi music season from mid-December to mid-January is the single biggest constraint in the city: every sabha auditorium is booked and every experienced freelance audio engineer in Chennai is committed to a kutcheri circuit for a month. Pongal in mid-January empties the labour pool for a week, Tamil New Year falls in April, and the automotive sector clusters its launches into January and February. Peak demand runs Nov–Feb.
Crew & dispatch
Own Chennai base, also serving Coimbatore, Madurai and Puducherry by road. Load-in support covers T Nagar, ECR and the rest of the city.
What it costs here
A value-conscious market where clients read line items closely and compare them against a competitive local supplier base, so a two-day conference quote is scrutinised item by item. The differentiator here has to be engineering and redundancy rather than discount, and it needs to be explained in those terms.
Local expectations
Muhurat scheduling is absolute and reshapes the whole production plan: a Brahma muhurat wedding ceremony at 5am means the rig is built, powered and soak-tested by 3am, with crew rostered for a night that ends at sunrise. Nadaswaram and thavil ensembles and live Carnatic groups need considered mic selection and a genuinely quiet stage, because a noisy monitor world is heard as a failure here. Tamil-first scripting with English support, and a client expectation that the technical team is present and silent rather than visible.
Specification
Simultaneous Interpretation Systems: technical specification
| Specification | Detail |
|---|---|
| Mobile booth standard | ISO 4043: approximately 1.6 x 1.6 x 2.0 m for two interpreters, insulated and ventilated |
| Built-in booth standard | ISO 2603 for permanently installed booths |
| Equipment standard | ISO 20109 for interpreter consoles, microphones and headphones |
| Distribution | Bosch Integrus infrared, confidential because it does not pass through walls |
| Channel capacity | Up to 16 language channels plus the floor channel on a typical deployment |
| Radiator coverage | Calculated from radiator power against floor area with line of sight to every seat |
| Interpreter staffing | Two interpreters per booth per language, swapping every 20 – 30 minutes |
| Audio feed | Clean direct feed from the console to each booth, never a room microphone |
| Relay interpretation | Pivot language routing where no direct language pair is available |
| Receiver logistics | Issued against delegate ID, counted back, charged overnight and sanitised between sessions |
The operational layer is the part clients underestimate. Interpreters work in pairs per booth and swap roughly every twenty to thirty minutes, because sustained simultaneous interpretation is cognitively unsustainable beyond that — a single interpreter per language is a false economy that degrades the session. They need the speaker's slides and script in advance, a clean direct audio feed from the console rather than a room microphone, and a technician who can patch relay interpretation when a language pair has no direct interpreter. Receivers are issued against delegate identification, counted back, charged overnight and sanitised between sessions, which is a logistics job in its own right at scale.

Venues
Where we work in Chennai
| Venue | Capacity | Production note |
|---|---|---|
| Chennai Trade Centre | Around 10,000 across four halls at Nandambakkam | Sits minutes from the airport with easy truck access, but the halls were built for exhibition stands rather than hung rigs, so roof point loads must be verified case by case and most designs end up ground-supported. |
| Nehru Indoor Stadium | Around 8,000 in concert configuration | An older indoor bowl where the roof carries no event rigging, so the full audio and lighting package stands on towers, and the marginal air-conditioning means a packed house will heat the rig as well as the audience. |
| ITC Grand Chola | Around 3,000 banquet in the largest hall, with a very large total banqueting footprint | One of India's biggest hotel convention complexes, but it is still a hotel: load-in is via a service dock with a height limit and everything rides a lift, so case and cabinet sizes are set by the building. |
| Kalaivanar Arangam | Around 3,000 seated | A government auditorium with fixed seating and house rigging, where approvals run through the state department that owns it and the build window is short and strictly policed. |
| Hyatt Regency Chennai | Around 800 banquet across the ballroom | Central Anna Salai location means night-only trucking, and the ballroom's clear height limits how tall a ground-supported LED wall can go before it fouls the ceiling coves. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- What can go wrong
A speaker reads from a prepared script at full speed and interpretation falls behind.
How we prevent itScripts and slides go to interpreters at T-2 weeks, and the chair is briefed to remind speakers that they are being interpreted, which is the single most effective intervention available.
- What can go wrong
Certain LED and plasma lighting radiates in the infrared band and corrupts channel reception.
How we prevent itCarrier frequencies are selected to avoid the interference band and a reception test is run with the full event lighting rig live, not with house lights only.
- What can go wrong
Receivers go missing because they were handed out without reconciliation.
How we prevent itIssue against delegate identification, a count at every break, and a documented reconciliation at session end — at a thousand units the loss rate without this is material.
- What can go wrong
Infrared coverage drops behind a pillar or under a balcony and a block of delegates hears silence.
How we prevent itRadiator placement is calculated against the seating plan and then physically walked with a receiver at build, with an extra radiator held for the shadow that is always discovered.
Honest comparison
Is this the right choice for your event?
- A curtained corner instead of an ISO 4043 boothOur verdict
There is no honest case for it on a session that matters. The booth exists to isolate the interpreter's own voice from the floor audio and to give them sight of the speaker; without both, accuracy falls and the delegates hear the result.
- Remote simultaneous interpretation instead of on-site boothsOur verdict
RSI is dramatically cheaper, removes booth logistics and gives access to interpreters anywhere. It depends entirely on connectivity and on the interpreter having a clean feed and good sightlines on video, which is fine for a routine webinar and genuinely risky for a high-stakes multilateral session.
- Consecutive interpretation instead of simultaneousOur verdict
Consecutive needs no booths, no receivers and no equipment — the interpreter speaks after the speaker pauses. It roughly doubles the length of every session, which is acceptable for a bilateral meeting and impossible for a full-day agenda.
