The high-fidelity wireless stereo audio transceiver is a wireless audio transceiver that integrates wireless stereo audio transmission and reception. The stereo audio signal input from the 3.5mm stereo audio port on the transmitter end is first sampled and encoded by a 24-bit stereo audio ADC at a 48KHz sampling rate, and then is transmitted to space in the form of a digital signal through the ISM band radio signal with a carrier wave of 2.402-2.480GHZ. After receiving the signal, the receiving end first verifies and decodes the digital signal and then outputs it to the 24-bit audio DAC to restore it to a stereo analog audio signal at the same 48KHz rate and output it to the 3.5mm stereo audio port. In order to solve the problem that multiple transmitters in the same signal coverage area transmit signals at the same time and different receivers receive the specified transmitter signal without confusion, this machine uses an 8-bit address encoding to distinguish only when the receiver address encoding setting is set with the transmitter setting. Connect only if they are consistent, otherwise do not connect. This machine adopts a proprietary 2.4G wireless communication protocol and codec algorithm, adopts a broadcast transmission mode, and supports one transmit and multiple receive. This machine is widely used in applications requiring wireless audio transmission, DIY wireless speaker modification and other applications. The machine can be set to work in transmitting mode or receiving mode using a DIP switch. You need to purchase at least 2 to form a transmitting and receiving set before it can be used. Buying just one will not work. This machine can only make wireless connections to transmit audio signals between the transmitter and receiver of the same model, and cannot wirelessly connect to other wireless devices.
