Short definition
A conference receiver is the small handheld device participants use to receive their chosen interpreting language and listen through headphones.
Detailed explanation
The receiver is the device handed to every participant. It receives the language channels distributed via infrared or radio and outputs the selected channel through connected headphones. Using a dial or button, the user chooses between the original audio and the available interpreting languages.
Three things matter for planning: quantity (enough devices for all participants plus spares), channel count (at least as many as there are languages), and hygiene/logistics (distribution, return, cleaning, battery charging). Infrared receivers need a clear line of sight to the emitters; radio receivers are less sensitive to obstruction but need frequency coordination. Headphones come as classic over-ear models, single-ear pieces, or chin-strap models.
Relevance in this subject area
The receiver is the final stage of the language chain – the only piece of technology participants actually touch. If it doesn't work, even the best system is useless.
Practical example
At a conference with 250 guests, 270 receivers are distributed (including spares). Each participant selects their language via dial; at collection points, devices are cleaned and recharged after being returned.
