Product Code:
527B Microphone
|
The 527B is wired for
balanced-line operation and is recommended for use where long cable
lengths are required, or areas where strong noise fields may exist.
The 527B microphone can be fed directly into a standard
low-impedance amplifier, or a Shure A95 Series Line Matching
Transformer can be used for coupling the 527B to the input of a
high-impedance amplifier. A two-conductor shielded cable can be
used for extending only the microphone circuit. If both the
microphone circuit and the remote circuit are to be extended, a
four-conductor cable, having two shielded conductors for the
microphone, should be used.
