If you have been quoted for simultaneous interpretation equipment rental in Hong Kong and the number surprised you, it is usually because the quote is not one thing. It is five or six things, each priced separately, and the largest of them is often the one nobody mentions until the load-in: the people.
This is a breakdown of what the kit is, what the published rates are, and which line items are missing from the version you were sent.
What is actually in a simultaneous interpretation kit
A working setup has five parts.
The booth. A soundproof enclosure so the interpreter’s own voice does not bleed into the room or into the floor microphone. Purpose-built mobile booths are built to an international sound-isolation standard — one Hong Kong supplier states its booths are certified to BS EN ISO 17651.1 A table with a partition is not a booth, and every interpreter will tell you so.
The interpreter console. The desk unit inside the booth: floor audio in, channel selection, a cough mute, and a relay function so a second booth can interpret from the first booth’s output rather than from the floor. This is the part that lets one interpreter hand over to their partner without a pause.
The transmitter and radiators. Infrared is the normal choice for conference work: the signal stops at the walls, which means it does not leak to the room next door, and it does not collide with whatever else is on the local radio spectrum. The trade-off is line of sight. Radiators have to see the seats, and a pillar, a deep balcony or a marquee with a low ceiling all need extra units.
A receiver and headset for every listener. This is the part that scales with headcount, and the part that goes wrong.
A technician. Someone who sets it up, tests every channel, stays for the event and fixes the one receiver that drops out. On most venue price lists this is a separate hourly line.
The published Hong Kong rates
Most rental houses quote privately. Two Hong Kong institutions publish their rate cards, which makes them useful anchors:
- East Kowloon Cultural Centre lists its simultaneous interpretation system at HK$8,200 per day, and only in two of its spaces — The Hall and The Theatre.2
- CUHK’s Audio Visual Services Unit charges external users HK$2,570 per three-hour block including 30 receivers and headphones, then HK$635 per additional hour, HK$20 per extra receiver and headset, and HK$430 per hour for a standby technician.3
Both are venue-owned systems, which is the cheap end. A commercial rental that has to deliver a booth to a hotel ballroom, build it, staff it and take it away again is a different number.
Where the maths breaks
The CUHK figures are the clearest way to see it, because they separate the base from the per-head charge.
A three-hour event for 30 people is HK$2,570 plus a technician. Call it HK$3,860 with one technician on site for the full three hours.
The same three hours for 200 people adds 170 receivers at HK$20 — another HK$3,400. You are now at roughly HK$7,260 for the equipment alone, before a single interpreter has been paid, and before anyone has worked out who is handing out 200 headsets at the door.
That is the shape of the whole category: a base cost that is bearable, and a per-head cost that makes a large audience expensive to listen, independently of how much it costs to translate.
What the quote does not include
Five things that are real costs and rarely appear as line items.
Distribution and collection. Somebody has to hand out receivers and get them back. For 200 guests that is two people at a desk for the half hour before the event and the ten minutes of chaos after it. In practice it is your staff, not the rental house’s.
Deposits and losses. Receivers walk. Most rental agreements make you liable per unit, and a conference receiver is not a cheap object. Collecting an identity card or a credit card at the desk is the usual defence, and it slows the door down.
Hygiene. Over-ear headsets are shared objects that go on a stranger’s head. Since 2020 most organisers either buy disposable covers or budget time to wipe every unit between sessions.
Set-up time in the venue. One Hong Kong supplier quotes two to four hours for a standard installation, depending on the size of the event and the complexity of the space.1 If your venue hire starts at 6pm for a 7pm event, the equipment cannot be installed in time, and the extra hours of venue hire belong on the equipment side of the budget.
Overrun. Interpretation is priced in blocks. CUHK’s additional-hour rate is HK$635; a commercial rate card will have its own. An event that runs forty minutes long usually buys a whole extra hour of everything.
The cheaper shape, and its limits
Not every event needs a booth. A tour-guide system — a handheld radio transmitter and a set of RF receivers — is the portable alternative, and it is a fraction of the price.
It works when the interpreter can whisper alongside the group: a factory walk-through, a site visit, a delegation moving between rooms, a small board meeting. RF passes through walls, so the group can spread out.
It stops working in a hall. There is no acoustic isolation, so the interpreter’s voice is audible to everyone nearby, including the people who are trying to listen to the speaker. For a seated audience of any size, the booth is not an upsell — it is what makes the room usable.
The one question that changes the number most
Ask the venue what it already owns.
A venue with an installed system removes the booth build, the delivery, the installation window and most of the technician’s hours in one answer. It is the single biggest variable in the quote, and it is answered by one email. The catch, as the East Kowloon example shows, is that installed systems are often limited to particular rooms in the building — so ask which rooms, not just whether.
What to ask the rental house
Six questions that stop the number moving after you have approved it.
- How many receivers are included, and what is the per-unit rate above that? The base number is usually 20 or 30.
- Is the technician included for the full event, or by the hour? And who stays if the event runs long?
- Booth or table-top? If it is a table-top unit, say so to your interpreters before you book, not on the day.
- How many languages? Every additional language is another booth, another pair of interpreters and another channel. This is the line that most often doubles a budget after approval.
- What is the liability for a lost receiver? Per unit, in writing.
- How long is the installation, and is the venue booked for it? Set-up time is venue time.
When you do not need receivers at all
Every receiver in the room is there to solve one problem: getting a second audio channel into an individual ear. Your guests are all carrying a device that already does that.
tlive runs the translation on a link. You put a QR code on the opening slide, each guest opens it on their own phone, picks their language and listens on their own earbuds. There is no base charge for equipment, nothing to distribute, no deposit, no hygiene problem and no per-head hardware cost — one link carries up to 250 listeners, and the bill is by the minute of the event rather than by the head.
It is not a booth and it is not an interpreter. It does not carry professional judgement, and for a negotiation or anything that will be quoted verbatim you should still hire a human. But for the AGM, the chapter meeting, the seminar, the chamber mixer and the three breakout rooms you were never going to fit a booth into, the receiver problem simply stops existing.
The honest comparison is on the Hong Kong page, with the published rates above set against what an event actually costs to run this way. If you want the interpreter side of the budget instead, what a simultaneous interpreter costs in Hong Kong covers rates, minimums and briefing.
