CARDIOID CONDENSER
HANGING MICROPHONE
- Designed for quality sound
reinforcement, professional
recording, television and other
demanding sound pickup
applications.
- Superior off-axis rejection for
maximum gain before feedback.
- Furnishing with a vinyl-coated steel
hanger that allows to be adjusted for
correct positioning.
- Accepts interchangeable elements
to permit angle of acceptance from
90° to 120°.
- Snap-on foam windscreen effectively
reduces noise from wind or
ventilation air currents.
- Connected power module can be
powered from any external 11V to
52V phantom power supply with an
XLRM-type connector.
- Enclosed in a rugged housing with
a low-reectance black nish. And
also available with white housing,
cable and hanger as the ES993W/C.
The ES933/C shall have a permanently-attached 15.2m miniature low-
noise cable, and require 11V to 52V DC phantom power 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 from the mic to the
rear-most pickup 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
performer. If additional mics are needed for wide sources, they should
be positioned apart laterally at least three times the distance to front
source, to avoid phase cancellation (Fig.2).
Output is low impedance balanced. The output connector mates with
XLRF-type cable connectors. The balanced signal appears across Pins
2 and 3, while the ground (shield) connection is Pin 1. Output is phased
so that positive acoustic pressure produces positive voltage at Pin 2, in
accordance with industry convention.
At integral 80 Hz high-pass filter provides easy switching from a flat
frequency response to a low-end roll-off. The roll-off position reduces
the pickup of low-frequency ambient noise (such as trafc, air-handling
systems, etc.), room reverberation and mechanically coupled vibrations.
Avoid leaving the microphone in the open sun or in areas where
temperatures exceed 43°C for extended periods. Extremely high
humidity should also be avoided.
