Interpretation Equipment in Delhi
Delhi's event economy runs on policy and procurement: ministries, PSUs, embassies, industry bodies like CII and FICCI, and the exhibition calendar at Pragati Maidan and Dwarka. Alongside that sits the farmhouse wedding belt from Chattarpur to Mehrauli, where single families commission production budgets that rival a mid-size corporate conference. Prime AV Solutions supplies the simultaneous interpretation systems behind those events — designed on paper, proven in rehearsal and run by our own crew.

Key takeaway
Simultaneous Interpretation Systems for Delhi’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 Delhi that plays out at venues like Bharat Mandapam, Yashobhoomi, JLN Stadium, and across Connaught Place, Aerocity, Chattarpur, Vasant Kunj.
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.

Local conditions
Producing interpretation equipment in Delhi
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. Two distinct problems bracket the season. From mid-December through January, radiation fog drops visibility under 100m and turns projection milky at any useful throw, while 3–5°C call times slow LCD response on monitors and stress LED driver boards before the first cue. Then from late October the post-harvest smoke layer pushes AQI past 400, which hazes beams attractively to the eye and reads as dirty grey on camera, so broadcast-led shows have to light for the haze rather than through it. May and June bring 45°C and loo winds that load filters within a session. Jul–Sep monsoon, where the real hazard is not rainfall volume but the short violent pre-rain squall that arrives in ten minutes and takes down an untethered outdoor structure; mid-Dec to late Jan if the design depends on projection throw.
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. NDMC, BSES and Tata Power supply in Lutyens, Aerocity and Dwarka is strong enough to run a conference on house power. The farmhouse belt is the opposite: Chattarpur and Mehrauli events are DG-primary, typically a synchronised pair of 250 kVA silent sets with auto-changeover. The complication unique to Delhi is GRAP — once the Commission for Air Quality Management escalates to the higher stages in winter, diesel generator use is curtailed unless the set is retrofitted or dual-fuel, so a December outdoor show needs its power strategy approved before the stage design is signed.
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. Amplified sound and temporary-structure NOCs route through the Delhi Police Licensing Branch, with ground permission from MCD, NDMC or DDA depending on whose land it is, and a Delhi Fire Service NOC for any pandal or raised structure. DPCC applies the noise rules and the 10pm loudspeaker cut-off. Drone operation is close to impossible on a normal timeline: most of the city falls inside the IGI red zone or a VVIP restriction, and anything beyond that needs clearance that goes well past a Digital Sky permission.
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. Goods-vehicle restrictions keep trucks out of much of the city through the day, so inventory moves from Okhla, Noida or Gurugram warehousing after 11pm. Pragati Maidan is easier since the tunnel opened, but ITPO gate passes have to be lodged days ahead. Yashobhoomi has purpose-built docks. The genuine trap is the farmhouse circuit, where a single narrow gate is shared with guest arrival, so load-in must be finished and the gate cleared before the first car turns in.
Season & booking
India International Trade Fair at Pragati Maidan through the second half of November absorbs every truss section, rigger and forklift in the NCR. Republic Day locks central Delhi for most of January with rehearsal closures from early in the month, state visits close roads without notice, Diwali week empties the labour pool, and the November-December and February muhurat clusters book out the farmhouse belt a year ahead. Peak demand runs Oct–Mar.
Crew & dispatch
Own NCR base with warehousing across Okhla, Noida and Gurugram, which also makes Delhi the dispatch origin for Jaipur, Agra, Lucknow, Gwalior, Ludhiana and Amritsar. Load-in support covers Saket, Rajouri Garden and the rest of the city.
What it costs here
The deepest supplier pool in the country sits here, which makes Delhi the cheapest place in India to hire kit — a comparable conference rig quotes well below its Mumbai equivalent — and clients negotiate accordingly. The margin lives in engineering, crew quality and compliance paperwork, not in equipment day rates.
Local expectations
Protocol is the deliverable at government and diplomatic events: dais seating order, the lamp-lighting sequence, anthem cues, correct honorifics in the script and a VIP arrival time that will move by forty minutes without warning. Bilingual Hindi and English scripting is assumed, as is a clean press feed. Punjabi weddings here expect high SPL and a finish past the curfew, which is why experienced producers push those clients towards acoustically contained indoor venues rather than fighting the enforcement.
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 Delhi
| Venue | Capacity | Production note |
|---|---|---|
| Bharat Mandapam | Around 7,000 in the plenary hall with multiple halls across the ITPO complex | Everything goes through the ITPO process — gate passes, approved-vendor paperwork and security screening of every case — so the build calendar has to start 72 hours before a build that would take one night anywhere else. |
| Yashobhoomi | Around 11,000 in the main auditorium plus very large convention and exhibition halls | The sheer footprint is the constraint: control positions end up a long way from stage, so fibre and signal distribution rather than copper multicore decides whether the design works. |
| JLN Stadium | Around 60,000 in the bowl, with the infield used for staged events | SAI holds the approvals, the athletics track and infield need full protection boarding, and the roof carries no event rigging at all, so even a modest stage needs ground-support towers with ballast calculations. |
| Siri Fort Auditorium | Around 1,200 seated | A fixed proscenium house with house rigging and a locked projection throw, so any design that wants a different screen position has to solve it with ground support in the wings. |
| Chattarpur farmhouse venues | Typically 1,000–5,000 across lawns and covered structures | Driveways are gravel or kutcha and will not take a loaded trailer without ground-protection boards, and almost every one of them is generated end to end with no usable house feed. |

Risk control
What goes wrong, and how we stop it
What can go wrong
How we prevent it
- 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.
- What can go wrong
A single interpreter is booked per language to save cost and quality collapses after half an hour.
How we prevent itWe quote two interpreters per booth per language as standard and explain why — sustained simultaneous interpretation beyond roughly thirty minutes is not reliably accurate.
- What can go wrong
Interpreters receive a room microphone feed full of reverberation and struggle to hear the speaker.
How we prevent itEvery booth takes a clean direct feed from the audio console, and the engineer monitors that feed on headphones rather than assuming it is right.
Honest comparison
Is this the right choice for your event?
- 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.
- Radio or Wi-Fi distribution instead of infraredOur verdict
Radio and app-based distribution cover more area and need no line of sight, which solves the shadowing problem. They also pass through walls, so a confidential session can be received outside the room — which is exactly why government and multilateral work stays on infrared.
- 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.
