Sennheiser Neumann BCM 104 Large Diaphragm Condenser Broadcast Microphone

Emotion conveyed with technical perfection. This is the ideal which the Neumann microphones in the Broadcast Line have been designed to fulfill. The fine-tuning to the requirements of professional broadcast studios and the individual, functionally optimized design ensure that these are microphones of character.

With its large-diaphragm condenser capsule and cardioid directional characteristic, the BCM 104 is ideal for the faithful reproduction of speech and music. This is due, for instance, to the frequency response that is flat up to 3 kHz and then gradually boosted in the higher frequencies. If required, internal switches can be used to compensate for the proximity effect and to reduce the sensitivity by 14 dB. The versatility of the BCM 104 can be seen in its wide range of applications, from news, to round-table discussions, to radio plays, to musical recordings.

The microphone headgrille twists off easily for quick cleaning. Neumann offers optional color-coded headgrilles so that, for reasons of hygiene, each announcer can use his or her individual headgrille. In front of the capsule, mounted on a frame holder, a fine gauze serves as a built-in popscreen.

The microphones of the Broadcast Line have an elastic mount against structure-borne noise, that is compatible with standard broadcast-segment microphone arms.

The microphone headgrille houses the K 04 large-diaphragm capsule, which has a flat frequency response up to 3 kHz. Higher frequencies have an increased presence up to 2 dB.

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.

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.

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 effectively.

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 (A-weighted).

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, an electronic high-pass filter, 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 circuits designed for dynamic microphones. But this will increase the self noise accordingly.

Both switches are located inside the microphone housing, since they will normally be operated only once, when the broadcasting facility is set up.

The preferred mode of operation is to suspend the BCM 104 or BCM 705 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 microphone by +/-90 degrees.

Sennheiser BCM 705 Microphone Finder

The BCM 705 is Neumann’s first dynamic microphone. The housing and headgrille are identical to those of the BCM 104; only the green logo indicates that this is something new from Neumann. The principle of reduction to the essentials can be seen in the dynamic capsule with a hypercardioid directional characteristic, specifically designed for speech reproduction at close range. Multi-level isolation from structure-borne noise ensures operation free of interference, even in a lively studio environment.

The microphone headgrille twists off easily for quick cleaning. Neumann offers optional, color-coded headgrilles so that, for reasons of hygiene, each announcer can use his or her individual headgrille.

The frequency response has a light treble boost, in the region from 2 kHz to 9 kHz, aiding the speech intelligibility. The bass frequency response is designed to compensate for the overemphasis of the bass caused by the proximity effect.

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.

Multi-level isolation from structure-borne noise

Its 15 different remotely controlled directional characteristics and numerous additional features permit the D-01 to be optimally adapted to almost any recording situation.

Sennheiser D-01 Digital Studio Microphone

Its 15 different remotely controlled directional characteristics and numerous additional features permit the D-01 to be optimally adapted to almost any recording situation. These comprehensive features demonstrate what can be achieved with digital microphone technology. The D-01 has a newly developed capsule, and is valued by users particularly for its hitherto unknown transparency and fidelity to detail.

Sennheiser DMI-2 Portable Digital Microphone Interface

The Digital Microphone Interfaces in general

Equipment that supports the AES 42 standard can process the output signals of Solution-D microphones directly. In all other cases, the DMI-2 portable or DMI-8 digital microphone interface is used. The DMIs convert the AES 42 data format supplied by the microphone into an AES/EBU signal.

The Interfaces are operated via the Neumann RCS remote control software, which is installed on a desktop or laptop computer. Some parameters of the DMI-2 portable can be accessed directly at the interface. The computer is connected to the DMI via a USB port and a USB to RS 485 interface converter. If a large number of microphones is used, several DMI-8’s can be cascaded. In this case, each digital microphone interface can be addressed individually.

In addition to a word clock input and output, the DMIs also have an internal word clock generator. If no master word clock signal (e.g. from a mixing console) is present at the input, the DMI internal word clock is used automatically to synchronize the microphone channels, and the signal is switched to the word clock output.

External commands such as "On Air" (red light) can be controlled via the 9-pin user port of the DMI-2 and DMI-8.

The DMI-2 portable is the ideal digital microphone interface solution for ENG and other field recording applications.

It supports two digital microphones and allows adjustment of the Gain, Pre Attenuation and Low Cut filter settings at the device. The front panel display shows the selected gain and, by means of bar graphs, shows the current signal level and any gain reduction. Of course, these functions can also be operated via the RCS software, which allows complete access to all of the microphone parameters.

Microphone presets can be stored inside the DMI-2 portable and recalled for use in the field.

Sennheiser AES/EBU Connection Kit

The Connection Kits serve to supply power to digital microphones, which are in accordance with the AES42 standard. The microphone audio signal is made available at the Connection Kit output in S/PDIF or AES/EBU format, depending upon the model.

The remote control and synchronization capabilities of the AES42 standard cannot be used with the Connection Kit; they are operable only with the DMI-2 or DMI-8 digital microphone interface.
