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.
OPERATION
The 527B will operate satisfactorily under all ordinary
conditions of humidity, heat, and cold. Dropping the
microphone or other severe mechanical shocks should be
avoided.
