Why Choose Digital Wireless Microphone System?

Excellent sound quality
Digital wireless microphone system provides high-quality transparent audio. This is largely due to the fact that digital wireless microphone system does not have a "compression expander", a circuit that reduces noise and maximizes dynamic range for all analog wireless microphone systems. Audio signals are compressed through transmitters to accommodate the limited dynamic range during FM transmission and then expanded in receivers.

In the process of compression and expansion, although most excellent analog systems are relatively small, there will still be some artificially audible sounds (such as the wheezing effect) that will make the voice of wireless microphones slightly different from that of wired microphones. Since the use of digital wireless microphones, the transmission of audio signals no longer requires compression and expansion, and the received signals restore the precise characteristics of the original audio.

Compressor-expandor (variable)
A digital wireless microphone system can reach the whole audible audio range with a flat frequency response curve.
Digital wireless microphone system converts analog audio into a digital signal by modulating radio carrier in several steps. The digital audio signal arrives at the receiver without the influence of electromagnetic noise. Any RF noise below the threshold does not affect audio quality. The receiver simply ignores anything that is not 1 or 0. Everything else was discarded. Only digital signals can be identified.。

Longer battery life
Usually, the electronic wireless microphone system has a 30% to 40% longer battery life than the same analog system. Here's an example of Schur: The digital signal transmitter ULX-D can run for 11 hours with two AA alkaline batteries and more than 12 hours with Schur SB900 lithium-ion rechargeable batteries.

Better spectral efficiency
By allowing tighter channel spacing, digital wireless systems can use more effective compatible frequencies in a certain frequency band at the same time. This feature is particularly important in the increasingly crowded UHF TV bands operated by many wireless microphones. With the help of manufacturers and models, digital wireless systems can usually deliver twice as many frequencies as analog wireless systems can use.
