ES933C/MIC & ES933WC/MIC
Cardioid Condenser Gooseneck Microphones
Installation and Operation
The ES933C/MIC requires a compatible Audio-Technica power module (not included)
for operation.
A uniform 120° angle of acceptance provides well-balanced audio pickup. The
microphone should be located forward of the front-most source, above the rear-most
source, and “aimed” between them (Fig.1). Increasing the height of the mic above
the sources will tend to equalize sound levels between them, but may also increase
background/ reverberant sound pickup. When possible, the distance from the mic to
the rear-most source should be no more than twice the distance to the front source,
to maintain front-to-rear balance (Fig. 1).
Width of pickup is approximately three times the distance to the closest source. If
additional mics are needed for wide sources, they should be positioned apart laterally at
least three times the distance to the front source, to avoid phase cancellation (Fig. 2).
Engineered Sound® Microphones
Features
• Uniform cardioid polar pattern with 120° acceptance angle
• Low-profile design with low-reflectance finish for minimum visibility
• Superior o-axis rejection for maximum gain before feedback
• UniGuard® RFI-shielding technology oers outstanding rejection of radio
frequency interference (RFI)
• Available interchangeable elements permit angle of acceptance
from 90° to 360°
• Steel hanger positions microphone over choirs, instrumental groups and
theater stages
• Available in two colors: black (ES933C/MIC) and white (ES933WC/MIC)
Description
The ES933C/MIC is a wide-range miniature condenser microphone with a cardioid
polar pattern. It is designed for quality sound reinforcement, professional recording,
television and other demanding sound pickup applications. The combination of small
size and excellent response makes the microphone ideal for suspension over choirs,
instrumental groups or theater stages.
The microphone requires a compatible Audio-Technica power module (not included)
for operation.
The microphone is equipped with UniGuard® RFI-shielding technology, which oers
outstanding rejection of radio frequency interference (RFI).
The microphone’s cardioid polar pattern provides a 120° angle of acceptance.
Additional interchangeable elements with omnidirectional (360°), hypercardioid
(100°) and MicroLine® (90°) pickup patterns are available.
To orient the microphone in the proper direction, twist the housing slightly in its wire
holder. (Clockwise rotation moves the microphone to the right; counterclockwise
rotation moves it to the left.)
The provided two-stage foam windscreen simply snaps over the head of the
microphone, eectively reducing noise from wind or ventilation air currents.
Avoid leaving the microphone in the open sun or in areas where temperatures exceed
110° F (43° C) for extended periods. Extremely high humidity should also be avoided.
Note: Audio-Technica has developed a special RFI-shielding mechanism, which is
an integral part of the connectors in the Engineered Sound® line. If you remove or
replace the connector, you may adversely aect the unit’s RFI immunity. AudioTechnica oers a crimp tool (ATCT) and RFI shields that enable you to shorten the
cable and correctly reinstall the connector while maintaining the highest level of
RFI immunity.

The microphone include a 15.2 m (50’) permanently attached miniature cable. Its
free end connects to a compatible Audio-Technica power module (not included) via a
special TA3F-type connector designed to optimize RFI immunity.
The microphone comes equipped with a vinyl-coated steel hanger for positioning
over a choir/orchestra/stage, and a two-stage foam windscreen. The microphone is
enclosed in a rugged housing with a low-reflectance black finish. It is also available
with white housing, cable, hanger and windscreen as the ES933WC/MIC.
