Apakah kelebihan mikrofon wayarles Digital?

1. Excellent sound quality

DigitalSistem mikrofon tanpa wayar provide high quality transparent audio. This is largely due to the fact that traditional wireless microphones do not have a "compression expander", a circuit that reduces noise and maximizes dynamic range for all analog wireless microphone systems.Isyarat Audio dimampatkan melalui pemancar untuk menampung julat dinamik yang terhad semasa penghantaran FM, dan kemudian berkembang dalam penerima.

Compression and expansion of this process, although relatively small in most excellent analog systems, 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 microphone systems, Penghantaran isyarat audio tidak lagi memerlukan mampatan dan pengembangan, dan isyarat yang diterima memulihkan ciri-ciri tepat audio asal.

2. Compression expander (variable)

AMikrofon tanpa wayar digital can achieve the entire audible audio range with a flat frequency response curve.

Digital wireless microphones Menukar audio analog ke isyarat digital dengan modulating pembawa radio dalam beberapa langkah. Isyarat audio digital tiba di penerima tanpa pengaruh bunyi elektromagnetik. Sebarang bunyi RF di bawah ambang tidak menjejaskan kualiti audio. Penerima hanya mengabaikan apa-apa yang tidak 1 atau 0. Segala-galanya telah dibuang. Hanya isyarat digital boleh dikenal pasti.

3. Longer battery life

Secara amnya, digitalSistem mikrofon tanpa wayar have a 30% to 40% longer battery life than the same analog systems. Some of our new digital wireless microphone systemsGunakan bateri lithium-ion yang boleh dicas semula, yang boleh berjalan sekurang-kurangnya 8 jam di bawah operasi biasa.

4. Better spectral efficiency

Dengan membenarkan jarak saluran yang lebih ketat, digitalSistem mikrofon tanpa wayar can use more effective compatible frequencies at the same time in a certain frequency band. This feature is particularly important in the increasingly crowded UHF TV bands operated by many wireless microphones. Dengan pengeluar dan model, digitalSistem mikrofon tanpa wayar can usually deliver twice as many frequencies as analog wireless systems can use.

Digital wireless microphoneTelah mengubah mikrofon wayarles tradisional dan membawa perubahan yang mendalam. Adalah dipercayai bahawa dengan perkembangan dan integrasi teknologi komunikasi moden dan teknologi komputer, ia akan menembusi semua bidang kehidupan sosial dan memainkan peranan yang semakin penting.
