SHURE SUPER-CARDIOID

H B R CA I) C A s '|' General: Models 556 and 55 are Super-

Cardioid type unidirectional moving-coil dynamic
microphones providing wide-range high quality repro-
duction of sound. The true unidirectional characteristic
of the Unidynes, obtained by the "uniphase" prin-
ciple provides highly satisfactory Operation under
adverse acoustic conditions where conventional micro-
phones would be practically useless.

The micrOphones have a New Acousto-Mechanical
circuit containing a moving-coil element, which Operating
in coniunction with a high flux magnet provides high
efficiency and smooth peak free response from 40 to
l5,000 cycles. The rear response is down approxi-
mately 15 db. due to the "uniphase" unidirectional
acoustic network.

The new moving-coil unit is provided with a double
wind-screen to permit quiet out-door operation. As a
precaution against mechanical vibration pickup, the unit
is spring-suspended inside the microphone case.

The cases are modern in design with attractive stream-
lining and grille treatment, and are provided with
swivels that allow the microphones to be aimed at the
source of sound for best pickup.

Applications: Model 556 is especially con-
structed and tested to meet the requirements of the
broadcast studio, and is held within close tolerances in
frequency response and directivity.

Model 55 is suitable for high-quality recording,
public address, and similar applications.

The true unidirectional characteristic of the Uni-
dynes provides an easy solution to the feedback
problem in reverberant locations, facilitates orchestral
placement, permits best utilization of space in small
broadcast studios, and allows practically complete
exclusion of unwanted noises. The swivel allows the
head to be tilted through an angle of 90°, permitting
the microphone to be aimed at the source of sound.
MODEL 556 The microphones are unusually rugged and are
practically immune to the effects of moisture, tempera-
ture and mechanical vibration.

Model 556 is a Dynamic Super-Cardioid Micro-
phone especially designed for Broadcasting. It is held
