AUDIO TECHNICA AT8024 Stereo/Mono Camera-Mount Microphone

With its lightweight yet feature-rich design, the AT8024 Stereo/Mono Camera-Mount Microphone offers a simple, powerful solution for capturing high-resolution audio for video. Selectable line-cardioid mono and internally matrixed mid-side stereo modes provide the flexibility to focus the recording on a single sound source or to widen the field for outstanding sonic realism. In either mode, the AT8024 delivers audio that is dramatically better than that supplied by the camera’s internal microphone.

The AT8024 camera-mount microphone also comes equipped with a three-position adjustable attenuator (-20 dB, -10 dB, 0 dB) to capture even soft and very loud sound passages without distortion. A switchable low-frequency roll-off reduces pickup of undesired ambient noise, room reverberation and mechanically coupled vibrations. The microphone is powered by a single AA battery for optimal performance with high max SPL, and features an integral camera shoe mount that attaches quickly to DSLRs and shoe-equipped camcorders.

Designed for video production and broadcast (ENG/EFP) audio acquisition, the AT8015 provides the narrow acceptance angle desirable for long-distance sound pickup, along with excellent sound rejection from the sides and rear of mic. The roll-off position reduces the pickup of low-frequency ambient noise (such as traffic, air-handling systems, etc.), room reverberation and mechanically coupled vibrations.

For when you need even more advanced recording than R-09's built-in mic
CS-15CS-15 For serious field recording, the optional CS-15 cardioid-type stereo microphone is a great match for the R-09. For portability and convenience, the R-09 supplies the power to the mic. Bundled with the microphone are a desktop stand, a hand-held mount, and a windscreen.
    
Cardioid-type stereo microphone
    
Battery operation is also possible when using with a recorder that doesn't supply the power
    
Ideal combination with the R-09 --- also the UA-4FX and the UA-1EX
    
Comes with a desktop stand, a hand-held mount (can be attached to the microphone stand) and a windscreen

Internally switchable proximity effect compensation and sensitivity reduction.

The BCM 104 condenser microphone is the first product in the new Broadcast Line,
which is especially tailored to the demands of professional radio announcing.
What sets the Broadcast Line apart is a completely independent, functionally-
optimized design derived from extensive 3D simulations.
The large-diaphragm condenser capsule used in the BCM 104 has a cardioid directional
pattern with internally switchable proximity effect compensation. A second switch allows
the sensitivity to be reduced by 14 dB.
The microphone headgrill twists off easily for quick cleaning. Neumann offers optional,
color-coded headgrills so that, for reasons of hygiene, each announcer working at an
announcing desk can use his or her individual headgrill.
Directly in front of the capsule, mounted on a frame holder, is a piece of fine gauze that
serves as a built-in popscreen.
The BCM 104 has an elastic mount against structure-borne noise, that is compatible with
standard broadcast-segment microphone arms.

Features:
Cardioid microphone for broadcast & studio
Large diaphragm condenser capsule with
switchable proximity compensation
Distinctive design
Integrated pop screen
Quick release head grille for easy cleaning
Individual head grilles available for each user

Acoustic features
The microphone headgrill houses the K 04 large-diaphragm capsule, which has a flat frequency
response up to 3 kHz. Higher frequencies have an increased presence of 2 dB maximum.
Since the above-mentioned microphone characteristics are obtained without the use of resonance
effects, the microphone features excellent transient response and transmits all transient phenomena
of music and speech without any coloration.
The integrated Pop Screen
A pop screen not only prevents the occurrence of plosive pop noises in vocal recordings, but also
efficiently prevents unwanted particles, from respiratory moisture, nicotine, to food remnants, from
settling on the diaphragm.
The pop screen can be removed for cleaning without the use of tools.

Electrical features
Instead of a transformer to couple the microphone output to the supply voltage, the BCM 104
has an electronic circuit which, like a transformer, provides for good common mode rejection.
Interference induced in the balanced modulation line is thus suppressed as usual.
With a very low self-noise of 7 dB(A), and an overload capability extending to 138 dB SPL,
the BCM 104 has a dynamic range of 131 dB (DIN/IEC 651).
Filter and Preattenuation
The BCM 104 amplifier has a linear operation down to 20 Hz. An active filter efficiently suppresses
signals below this frequency. In order to compensate for the proximity effect, a high-pass filter,
electronically activated by a switch, is built into the microphone. This filter reduces frequencies
below 100 Hz by 12 dB/octave.
A 14-dB preattenuation switch is provided in order to adjust the sensitivity, if necessary,
to transmission circuits designed for dynamic microphones. But this will increase the
self noise by 14 dB.Both switches are located inside the microphone housing, since they
will normally be operated only once, when the broadcasting facility is set up.
Mounting
The preferred mode of operation is to suspend the BCM 104 from a standard studio boom arm.
A thread adapter to fit different connector threads is included.
In order to provide protection from structure-borne noise, both the capsule and the microphone
in its mount are elastically suspended.
The optional SG 5 swivel mount allows additional angling of the BCM 104 by +/-90 degrees.

Application hint:
While designed to be an announcer's mic for broadcasting and studio, this is
just one of the most common applications. With additional experimentation,
you will gain maximum use from this microphone.
