Feature:
Support through-wall transmission: it can transmit through obstacles such as walls, ceilings, wood, glass, etc., to solve the problem that Bluetooth cannot obstruct transmission
Support one sending and multiple receiving: up to 1 sending and 20 receiving, receivers can be purchased separately to add receivers
Transmitter TX: Transmit Bluetooth wireless audio from laptops, mobile phones, set-top boxes, Bluray DVDs and other devices, 3.5mm or RCA output audio signal (need to purchase an adapter cable)
Receiver RX: Decode the received audio signal and transmit it to active speakers and amplifiers, etc. Any equipment with optical SPDIF, coaxial 3.5mm or RCA input
Transmitter applicable equipment: mobile phones, computers, laptops, tablets, iPads, TV boxes, etc.
Receiver applicable equipment: speakers, headphones, etc.
Transmitter connection method:
1.3.5mm audio output port connection: if the signal is interfered during audio transmission after the power is connected, it can be solved by switching the channel through the channel button (CH) of the sender when the power is on. Each time you press the switch key to switch a channel. Please select the channel with the best sound quality, there are 20 channels to choose from. The channel will be updated automatically after the receiving end is powered on again
2. Bluetooth connection: Turn on the phone's Bluetooth, search for LZXBT and connect. When using Bluetooth connection, do not plug the audio cable into the AUX IN port
Receiver connection method:
Support coaxial/3.5AUX/optical fiber connection equipment
Two power supply methods:
1. Use the USB interface of the computer, speaker, set-top box and other equipment to supply power
2. Powered by a charging plug with a USB interface
