- General interface international 2.4GHz wireless audio frequency hopping multi frequency technology grou.16 group alternative channel,40 bit world's only alternative address code digital encryption,digital squelch with memory function,all inport main chip, CD quality standard 44.1K/16 bit high sampling rate, non compression way original direct transfer, with WOLFSON audio CODEC,ensures that the output quality pure and true,without noise.
- You don't need to lay wires and it provides high quality audio free transmission more than 40 meters (L.O.S.no obstacle)
Parameter Index:application scope: general 3.5mm or RCA audio interface speaker equipment (power amplifier, computer speaker, MP3 digital TV set top box, TV, etc.)
- L.O.S*=No obstacle transmission distance-- Light of Sight Abbreviated to Line-of-sight range
- The lithium ion in the battery can be fully activated after the new battery fully changed and discharged.The battery can reach the finest state.The former three times,you had better charge 12 hours,no more than 24 hours.
- The device transmits frequency band is 2.4G.It is the same frequency band (but different channel) as wireless router, please keep distance channel with router.
- You do not need the following equipment matching operation except in special circumstances:simultaneously press the M key for transmitter and receiver devices, don't let go.Then let go simultaneously when the two devices blue lights begin to flash quickly, and wait for the indicating lamp to stop flashing, shutdown. Pairing ends.

Performance Comparison:
- 2.4GHz all digital audio transmission mode
Audio:Good quality, CD class quality
Signal-to-noise ratio:High signal-to-noise ratio, 90DB, no bottom line
Frequency response:20-20KHz full band
Stereo:Support 2 channels
One transmitter multi receiver:Support one transmitter N receiver,multi transmitter N receiver
Channel isolation:85dB high isolation, no crosstalk
Frequency stability:All digital IC PLL does not change channel.
Confidentiality:Privacy excellent, 40 digit address code pairing
Anti-interference:very good. There is a frequency hopping mechanism to avoid interference
Penetrating power:commonly
Application range:Home audio, home theater, etc., for higher quality products
Channel licensing:2.4GISM global licensed wireless universal channel
- Analog audio transmission mode in 600-800MHz or other FM mode
Audio:The quality is sound, and the treble and bass are very poor
Signal-to-noise ratio:SNR is low, 40DB, bottom noise is obvious, inevitable
Frequency response:100-13KHz high note missing, low bass
Stereo:support
One transmitter multi receiver:support  
Channel isolation:35dB isolation is low and crosstalk is possible
Frequency stability:The external phase locked loop parts are scattered and easily disturbed to change channel
Confidentiality:no privacy
Anti-interference:Bad, disturbed by cell phone signals
Penetrating power:preferably
Application range:Generally use the distance is far,the quality of the product is not too high requirements
Channel licensing:Unauthorized channels may use legal channels for legal disputes

Noise checking method:
- Just turn on the receiver and speakers, and listen if there is any noise. If there is no noise, move on to the next step
- Switch on the transmitter, not connect the signal wire, listen if there is any noise.If there is no noise, move on to the next step
- Receiver host, place it apart from the transformer and AC power lines as far as possible to avoid wire interference to the audio.
- Check if the audio wire is plugged in, then check the sound source or change the audio source.
- If the sound source is no problem, only press the M button on the side of transmitter to change channel (Make this device far away from the router)

Note: Make sure the pickup or Mike must be high level output, you can input and use the device.
The receiver is high impedance output, so it will lower the volume when connecting the ordinary earphone and power amplifier
