Tech-Protect Ultraboost AU02 Audio Adapter AUX Bluetooth 5.4 Black
Description
Description
Tech-Protect Ultraboost AU02 is a dual-function Bluetooth 5.4 audio adapter with a 3.5 mm AUX output, which works as both an receiver (RX) and a transmitter (TX) of audio signals. With a mode switch on the case, one device replaces two – you can wirelessly receive sound from your phone on a hands-free set or car speaker, but also transmit sound from your TV, computer, or projector to wireless headphones.
Operating Modes
In RX mode (receiver), the adapter connected to a speaker, car kit, or amplifier receives audio signals from a phone or other Bluetooth device and plays them through the connected equipment. The built-in microphone allows for hands-free calls directly through the car kit. In TX mode (transmitter), the adapter connected to a TV or computer through the AUX jack wirelessly transmits sound to Bluetooth headphones or speakers – perfect for watching movies or listening to music without cables.
