UNIDIRECTIONAL DYNAMIC MICROPHONE
WITH BUILT-IN VIBRATION-ISOLATION SHOCK MOUNT
General: The Model 566 Microphone is a unidirectional
dynamic microphone with a strong, built-in, wire-mesh
spherical front that contains a very effective filter designed to provide excellent protection from wind and
"pop" (explosive breath sounds). The built-in vibration-isolation shock mount prevents the pickup of
mechanical vibrations. The unit provides wide range
reproduction of music and voice -can be effectively
used outdoors and indoors.
The Unisphere I is ideal for use by professional en-
tertainers in high quality theatre-stage sound systems,
indoor or outdoor recording, cathedrals and churches,
and critical public-address systems such as those used
in political conventions and legislatures, convention
halls, hotels, public auditoriums, stadiums, etc.
The Model 566 features an exceptionally uniform
and effective unidirectional pickup pattern-provides
an easy solution to feedback problems in reverberant
locations, permits best utilization of space in small
studios, facilitates orchestral placement, and provides
practically complete exclusion of unwanted noises.
Microphone Features:
A built-in wire-mesh screen and internal filter
provides protection from wind, and "pop" (explosive breath sounds). This filter also enables
singers and speakers to perform close to the
microphone.
Unusually effective cardioid pickup pattern
eliminates feedback (annoying loudspeaker
"squeals"). In addition they prevent echoing
(boominess) that sometimes occurs in
filled halls. These microphones can also be used
closer to loudspeakers than usual, without
creating feedback problems.
Response especially effective for announcing,
narration, vocal music and combo groups.

The Model 566 is dual impedance, 50 ohms or 150
ohms, for connections into microphone inputs rated at
25 to 250 ohms.

The microphone is recommended where long cable
lengths are required or under conditions of severe hum
disturbance. The permissible cable length is practically
unlimited, since neither response nor level is appreciably affected. For use with high impedance amplifiers,

turned to the wrong impedance setting during use as
"ON-OFF" switch.
