8CH Speaker/Receiver Unit Tester Type BK9012
The Automatic Microspeaker Tester:
Based on the BK2120A Audio Analyzer, the BK9012 is designed to
quickly test microspeakers or receivers 4~8 at a time at a rate
that you’ll find hard to keep up with. It tests various
frequency characteristics and also rub & buzz so you know
the quality of your product is maintained. And of course, you
can track the accuracy and stability of your process using
the data you’ve saved on about 4 million microspeakers
(based on a 6 second total test + load time) per month.
