General:
microphone, built to provide wide-range reproduction of music and
voice and featuring an omni-directional
phone has complete versatility and reliability for outdoor and indoor use and may be used in the following manner:
I.
Mounted in swivel adapter on a conventional floor or desk
stand.
2. Quick disengage feature permits the microphone to be removed from the swivel adapter for use as a
participation, interviewer microphone, etc.
Equipped with adjustable lavalier cord and belt clip, the micro-

announcers, etc.
4.
Readily accessible impedance switch permits quick change
from the
low impedance setting for use with long lines, broadcast equip-
ment, etc.
When equipped with the accessory switch adapter Model A500
5.
(separately available), the unit will serve in applications where
an "ON-OFF" switch is necessary at the microphone.
The smooth frequency response and attending faithful reproduc-
tion is largely due to a newly designed diaphragm attached to
sensitive coil suspended in a magnetic structure. The use of high
efficiency magnetic materials and
circuits has made

The microphone is ruggedly built to withstand hard usage and
is unaffected by temperature and humidity variations. The 20 foot
broadcast-quality, shielded, two conductor cable is supplied with
an
XL-3-1 I Cannon microphone plug.
The "530" meets the most exacting requirement for maximum
quality and minimum size. A self adiusting swivel adapter is supplied with the microphone and permits the microphone to be tilted
through
the microphone at the source of sound.
An adjustable lavalier cord and a belt clip are supplied which
facilitate the use of the microphone for public
turers; teachers and instructors; demonstrators and all similar
cations where freedom of both hands is necessary. The lavalier cord
