Short definition
Pocket transmitters and pocket receivers are the two portable devices of a portable guide or whisper system: the transmitter carries the speaker's voice, and the receivers deliver it to listeners.
Detailed explanation
These two devices form the core pair of any PGS/whisper system. The pocket transmitter is worn by the speaker or interpreter; a microphone (often clip-on or headset) is connected to it, and it sends the signal via radio. Listeners wear the pocket receivers, which receive the signal and output it through connected headphones – whether single-ear, over-ear, or chin-strap models.
Important considerations when planning include channel selection (multiple channels allow parallel languages or groups), range and frequency coordination (so neighboring systems don't interfere), battery life, and quantity and hygiene during distribution. A single transmitter can supply any number of receivers – ideal for larger groups. For multiple languages, several transmitters on different channels are used, between which receivers can switch.
Relevance in this subject area
Pocket transmitters and receivers are the concrete building blocks of mobile language transmission. Knowing their properties helps plan channels, range, and quantities correctly.
Practical example
For a bilingual tour, two pocket transmitters (one language per channel) and 40 pocket receivers are used; guests select their language on the receiver and switch as needed.
