Sennheiser’ have launched the
MKH 8000 series of condenser microphones. If you want to know more, here’s their press release in full…
Take a unique microphone
principle, an extremely small, modular design and a sound reproduction with a
unique clarity and a natural, subtle warmth. The result is a series of
microphones that can capture the true heart and soul of sound without losing
any of its transparency or power. The MKH 8000 series of RF condenser
microphones from audio specialist Sennheiser sets new standards for top-
quality speech, vocals and instrumental recordings with an extremely wide
frequency response.
“With our new MKH microphones we have consistently advanced the high-end
technology of the RF condenser microphone and the wider frequency
response of the MKH 800,� explains Sebastian Schmitz, Product Manager for
microphones. “The technical development was supported at a very early stage
by sound and listening tests, and the sound engineers involved in the tests
confirmed that the new microphones have an incredibly impressive sound
quality that even goes beyond that of the innovative MKH 800. In response to
many requests from long-term users, we are also offering a wide range of
accessories for the new MKH microphones, allowing them to be optimally
adapted to the highest-quality classical music, stage, broadcasting and film
recordings.�
Two parts — a clever solution
The new series of high-end microphones presently includes three models: the
MKH 8020 has an omni-directional pick-up pattern, the MKH 8040 is a cardioid
version while the MKH 8050 has a super-cardioid pick-up pattern. All three
microphones consist of two modules: the microphone head that contains all
the acoustically important components, and a separate XLR module. If you
need to make the already compact microphone (only 1.9 cm in diameter and
7.4 cm long) even smaller, you can detach the XLR module, connect the
microphone head (4.1 cm) directly to one of Sennheiser’s special remote
capsule accessories, and then simply attach the XLR module to its end, out of
shot of the camera. A further optimised feature for TV recordings is the dark
grey Nextel® coating. This ensures that neither the microphones nor the
accessories can cause troublesome reflections that might otherwise distract
musicians, vocalists or speakers.
Compact design — huge frequency response
The frequency response of the new MKH microphones ranges from 10 to
60,000 Hz (MKH 8020) or 30 to 50,000 Hz (MKH 8040 and MKH 8050) —
allowing them to record even the finest details for high sampling rate digital
audio formats. The RF condenser principle means that inherent self-noise is
extremely low, while the high sensitivity of the microphones guarantees that
voices and instruments are captured in all of their nuances. In spite of this, the
maximum sound pressure level is still impressively high, at 138 dB for the
MKH 8020 and 142 dB for the MKH 8040 and the MKH 8050. Great attention
was paid to achieving an accurate pick-up pattern over the entire frequency
response, for example to allow instrument groups to be clearly separated.
In a class of their own: the accessories
The complete range of accessories includes floor stands, extension tubes,
shock mounts, remote cables, table stands, ceiling mounts, clamps and
various fixtures. In all accessories, the signal-transmitting components are
systematically designed with two channels to allow stereo signals or dual
mono signals to be processed.
In addition, a digital module that transmits audio signals according to the
AES 42 standard (24 bit, up to 192 kHz sampling rate) is expected to be
available in 2008. The module features a DSP unit for adjusting pre-attenuation, rumble filter, compressor and limiter settings. These settings can
also be remote controlled using a digital interface such as the DMI-2 from
Neumann.
Sennheiser’s Tonmeister Gregor Zielinsky: “The heart and soul of music is in
the mid-range frequencies — and this is precisely where the new MKH
microphones reproduce the sound particularly well and warmly without taking
away from the unique clarity that these microphones are famous for. They
have an impressive transparency in complex musical arrangements, especially
when it comes to providing good differentiation between wind instruments and
strings. Their fast transient response, also in the bass range, ensures a very
powerful and dynamic sound reproduction and recordings that are musically
outstanding.�
The operating principle of the radio frequency condenser microphone
RF condenser microphones constitute a unique, sophisticated class of
condenser microphones. Unlike standard condenser microphones, which
require a high polarisation voltage for the capsule, RF condenser microphones
use a comparatively low RF voltage generated by a low-noise oscillator. This
voltage is modulated by the changes in capacitance produced by the sound
waves that move the capsule diaphragm. Following the demodulation, a low-
noise audio frequency signal with very low source impedance is available, and
this can be used to directly drive bipolar transistors that produce less random
noise than the field-effect transistors usually needed. As a result, RF
condenser microphones have a wide dynamic range and an excellent low
frequency response even with small capsules, which would normally only be
possible using larger capsules. In addition, small capsules achieve a
considerably better high frequency response than large capsules. A further
benefit of RF condenser microphones is that, although the capsule is
grounded, they possess a genuine fully floating, balanced output without the
need to use a transformer.
Sennheiser’s revolutionary symmetrical microphone capsule
Sennheiser’s RF condenser microphones have a unique symmetrical push-
pull transducer. Besides the normal back plate, this capsule is fitted with an
additional front plate, with the diaphragm positioned between these
acoustically transparent plates. The result of this balanced design is an
unchanging acoustic impedance, extremely low distortion figures, a higher
capsule output with much lower noise and thus a very clear signal.
