Description:
 

Audio signals not balanced would cause audio signal noisy that happened on weak, strong differential signal into audio amplifier, DVR, monitor or audio /video image processing equipments.
Other case like under long range cabling cause 'Impedance not Matching'. The audio transformer filter is designed with multi- stage high common mode noise and jamming rejection, audio termination and audio filtering circuits for most of high noise environment.
 

Features:
 

BNC male to BNC female with 165mm mini cable 15 on both sides
Perfect work with Audio Amplifier/ Audio Speaker/ DVR/monitor to immunity Audio Amplifier/DVR/monitor interference
Built in a highly balanced commond mode noise rejection of audio transformer
Audio line termination and LPF audio filter block circuits for noisy rejection, which are immune to interference from these, and other sources of noise: Data signals, other video signals, nearby power, ringing telephones, fluorescent lights, transformers, and more...
