A new generation of digital audio sound reinforcement equipment of modern only anti howling frequency shift series products are

 

the company designed for equipped with conference, teaching. The internal line adopts five section parametric equalization and

 

digital frequency shift dual Whistler preventing technology, effectively improve the distance between the microphone pickup,

 

microphone gain is increased to 5~14db, speaker relaxed and natural. Because of the whistler preventing effect, more

 

effectively protect you after class attack and defense and speakers and other expensive equipment, is the protection of God

 

sound reinforcement equipment. On the humanization design make your operation more simple, do not need to debug before

 

the meeting, open the power you can immediately enter the conference. Exquisite workmanship, precise and reliable. Clear

 

sound quality, high fidelity, ensure the transmission quality of speech. Choose freely. Volume independently adjust, bring you

 

easily debug selection.
