Joyo JW-01 wireless digital audio system for electric string instruments gives electric instrument(guitars, violins, ukuleles, etc.) players the freedom to move around without worrying about tumbling over the cables used to connect the instrument and the PA system. It operates with bluetooth technology and is very easy to set up. Joyo JW-01 wireless audio system employs GFSK technology, Gaussian frequency-shift keying. GFSK is a type of frequency shift keying modulation that uses a Gaussian filter to smooth positive/negative frequency deviations. It minimizes the audio data distortion and loss of signal because the audio data is transmitted in a reduced spectral width. Also GFSK is relatively immune to noise in transmission. The digital modulations employed in transmission of audio ensure the high CD quality of musical sound from your guitar to the amplifier. The requirement of the pairing of the transmitter and receiver perfectly reduces RF signal interference in the surrounding environment. All of the above advantages are not possible for VHF wireless systems. Enjoy it, musicians!
