Sunlight 139B LoudSpeaker Polarity Tester
In a HI-FI Stereo System, Loudspeaker & Headphone with a correct polarity is very important. If the
phase ( polarity ) was reversed, HI-FI Stereo’ s effectiveness would be seriously affected. 139B is not
affected at all in a noisy place, and can judge at once the polarity of the loudspeaker and headphone. 139B
can be connected with 152A, 7117K, 7116C to test 4 parameters. Only one operator is needed ( see left
page ) .
139B is suitable for loudspeaker system, loudspeaker, multimedia, monitor, headphone and audio
firms.
