This transducer is intended to be used together with the head of an U47 microphone (and similar microphone heads) instead of the original M7 transducer. Assembly with original 32mm holder or our holder STS7.

There's another version of K47 that works with K47 transducer instead of M7. In connection with the ring STR32/34 our transducer STW7 can be assemled to this U47 too and replaces screwed K47 transducer.

On demand we can deliver STW7 with only one connector wire instead of two yellow ones to be installed to M7 capsule.

It is possible to assemble STW7 together with STR32/34 to the segment of K47 head of K47fet. For this purpose we offer STW 7.1
