Description
AU682 Audio Adapter Digital Display Wireless Audio Transmitter Receiver for TV Computer
Straight line distance of 200 meters, can go through the wall, the transmitter supports mobile phone Bluetooth connection, receiver with 3.5MM audio port, coaxial audio port, SPDIF fiber output port, the sound quality can reach 192khz/bit high-end HIFI level.
The transmitter and receiver are powered by USB and can be powered by any device USB port (power supply is not included)
The transmitter adds the Bluetooth connection function of the mobile phone
The transmitter has a display screen, which can display the channel, which is more convenient to use
When not using Bluetooth transmission, the transmitter can use the 3.5MM interface alone to connect to the computer, mobile phone, player, and other signal sources to wirelessly transmit audio
The receiver has an optical SPDIF output, which can reach 192kHz/bit HiFi level
The receiver also has a coaxial output, 3.5MM audio port output, and wireless transmission of sound quality is more stable and clear
