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.
