System introduction

LP - 1000 is a professional of anti noise processor designed for conference room, the product adopts the latest digital intelligence

Can technology of frequency shift and the feedback inhibition method, can effectively suppress the noise, it emphatically solve amplification stability and sensitivity

And amplification of clarity that three problems, artificial acoustic feedback effectively, significantly reduced the microphone noise, make the phone

Sound transmission gain (3 db - 11 db) to obtain maximum amount of space, so that the entire audio equipment potential also get most

Limit.

Technical parameters
