Audio transmitters and receivers add wireless audio to equipment that was never built with it: Bluetooth transmitters that send sound from a TV, PC, or audio jack to wireless headphones or speakers, receivers that bring Bluetooth streaming into powered speakers or stereo systems that predate it, and combo units that switch between both roles. Where the source or the speaker lacks Bluetooth, one of these bridges the gap.
Match the unit to the direction audio needs to travel - transmitting from a source device or receiving into a speaker system are different roles, and combo units need to be set to the right mode. Check the audio codec and range against the use case; conference rooms and TV setups benefit from lower-latency codecs so sound stays in sync with picture. Battery-powered transmitters suit portable use, while units drawing power from the host device suit fixed installations. COLAMCO supplies Bluetooth audio adapters for the existing audio equipment business, government, and education users want to make wireless.
