This document is the User's Manual for the Monoprice Bluetooth® Long Range Transmitter and Receiver, P/N 43243.
Function Description:
The Monoprice Bluetooth® Long Range Transmitter and Receiver is a versatile audio device designed to add Bluetooth connectivity to a wide range of audio equipment. It can operate in two primary modes: Transmitter (TX) mode and Receiver (RX) mode. In TX mode, it allows non-Bluetooth audio sources (like TVs, MP3 players, or DVD players) to transmit audio wirelessly to Bluetooth-enabled headphones, speakers, or other receivers. In RX mode, it enables non-Bluetooth audio devices (like wired speakers, amplifiers, or headphones) to receive audio wirelessly from Bluetooth-enabled sources such as smartphones or tablets. The device supports long-range Bluetooth transmission and reception, enhancing flexibility in audio setups. It also features multipoint connection capabilities in both TX and RX modes, allowing it to connect to two receiving devices simultaneously in TX mode or receive audio from two source devices in RX mode (though only one can play at a time).
