Noise Filtering CapabilityDigital signals take only two values: 1 or 0 and therefore it will be easier to differentiate between the noise and signal when noise interferes with these signals.
Communicate FirmlyIn full duplex two-way radio communication, the transmitter and receiver can communicate with each other, therefore if an error occurred the receiver would requests the transmitter resends the signal automatically(DW-25).
Distortion-Free ReproductionDigital amplifier development is poised to become a mainstream and digital amplifier and speaker will be obtaining a distortion-free sound while communicating with digital wireless microphones.
Digital wireless features FHSS(frequency-hopping spread- spectrum) technology that divide the frequency into a number of small channels, and signals is switched rapidly between them in a random sequence that is known by both the receiver and transmitter. It achieves a good capability of anti-interference that can work under every complicated environment with high performance.
Digital wireless system allows full dynamic range without audible noise, as the audio signal is not compressed in the transmitter and expanded in the receiver. Since there are no compander circuits to muck up the sound, the sound from digital wireless would sound better than analog system.
It operates on global license ISM BandThe ISM (Industrial, Scientific and Medical) bands are open frequency bands that allow for operation without a license, these are also known as the unlicensed bands.It also means that CAROL's DW-882 and DW-25 wireless microphone system can be used by anybody without a license all over the world.

Break the Geographical Boundaries
One 2.4G System to Fit All.You don't have to make a significant investment to buy multiple models with variety frequencies for different location requirement. This is a huge motivation makes more and more system integrators and consumers transferred to 2.4 GHz wireless microphone systems.
