BOYA BY-MM1 Universal Cardioid Shotgun Microphone 3.5mm

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.

The new RODE NTG-1 is a lightweight condenser shotgun microphone, specifically
designed for professional applications within the film, video, television, voice-over and
ENG industries.
The NTG-1 provides an electronically balanced output stage and operates on 48 V to
the P48 standard. The NTG-1 offers wide bandwidth and a controlled polar response
coupled with low noise SMT electronics. The NTG-1 is extremely lightweight making it
ideal for mounting directly to video cameras (with optional accessories) or a Boom pole.
The NTG-1 comes complete with mount and windshield. The supplied windscreen effectively
suppresses wind noise when recording outdoors in moderate conditions. Optional accessories
are available for more demanding applications.

This product, like the VideoMic (VM), now the worldʼs biggest selling on camera shotgun microphone, is also destined to become an Industry standard and not only offers the same sound quality & performance as itʼs predecessor, but also meets the industry demand for stereo recording.

Now videographers may use true ʽstudioʼ stereo recording techniques in the field with ease. The X/Y configuration enables the SVM to capture the true ambience of the recording space, while still offering a high level of rear rejection and low noise.

Fitted with a shoe mount, the SVM has the same low noise circuit design as the VM. The SVM offers 9V battery operation, an LED battery status indicator, a high pass filter switch, and a -10dB pad switch which allows for the mic to be used on most cameras with perfect level control.

You can also use the SVM as a remote mic on a stand, or a RØDE boom pole (Optional Accessory), which truly makes this versatile product well suited for all video applications including Electronic News Gathering (ENG), Weddings, Sports Events & Interviews. Rode Stereo Video Mic Features
