Description
The ATND933aML is a wide-range miniature condenser microphone with
a MicroLine® (line cardioid) polar pattern. It is designed for quality sound
reinforcement. The combination of small size and excellent response makes the
microphone ideal for suspension over choirs, instrumental groups or theater stages.
The microphone is equipped with UniGuard® RFI-shielding technology, which oers
outstanding rejection of radio frequency interference (RFI).
The microphone’s MicroLine® (line cardioid) polar pattern provides a 90° angle
of acceptance. Additional interchangeable elements with omnidirectional (360°),
cardioid (120°) and hypercardioid (100°) pickup patterns are available.
The microphone includes a 15.2 m (50') permanently attached miniature cable. Its free
end connects to the provided ATND8734a Dante-enabled wall/ceiling plate power
module via a special TA3F-type connector designed to optimize RFI immunity. The
power module features a removable, circular cover plate that can be painted with
commercially available spray paint. The power module includes an RJ-45 output jack
for easy connection to the network via CAT5e (or better) cable. Additionally, logic input
screw terminals accept an external switch for connection to the Dante™ network.
The power module is equipped with an 80 Hz low-cut UniSteep® filter, three-position
input gain level selector (+30 dB, +40 dB and +50 dB), and red/green LED status
indicator, which can all be controlled remotely via third-party software.* Default settings
for the power module are as follows: low-cut filter o, +40 dB input gain, LEDs o.
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 ATND933aWML.
Installation and Operation
A uniform 90° 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 1.5 times the distance to the closest source. If
additional mics are needed for wide sources, they should be positioned apart laterally
at least 1.5 times the distance to the front source, to avoid phase cancellation (Fig. 2).
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.
The power module allows for remote control of a high-pass filter to provide easy
switching from a flat frequency response to a low-end roll-o. The roll-o position
reduces the pickup of low-frequency ambient noise (such as trac, air-handling
systems, etc.), room reverberation and mechanically coupled vibrations. Mic gain and
LED ring color may also be controlled remotely through the power module.
The power module is equipped with logic input screw terminals which can be used
to trigger functions on compatible Dante-enabled devices, such as a video camera’s
pan/tilt or a rooms lighting preset.
The ATND8734a wall/ceiling plate power module is designed to be mounted in a
standard metal U.S. 2-gang electrical box. For safety and best performance, use the
electrical box only for the ATND8734a; do not include any AC power conductors.
Connect the TA3F-type connector on the microphone cable to the TB3M-type
connector in the power module plate.
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. Audio-Technica 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.
