NEW ELLIPTICAL BOCK AUDIO 5-ZERO-7 MICROPHONE
LAS VEGAS, NEVADA - SEPTEMBER 2008: TransAudio Group, the worldwide
distributor for Bock Audio, is launching the new Bock Audio 5-ZERO-7 hand-built, large body tube microphone at the 125th AES Convention in San
Francisco.
Designed to be the ultimate in studio vocal microphones, the Bock 5-ZERO-7 is a new approach in high-end mic design that combines a unique and
patent-pending elliptical capsule with a vintage-inspired, fully discrete, tube mic amplifier and custom power supply.
The new elliptical capsule design by David Bock and George Cardas strives to
resolve the chronic in-band resonance issues of both large and small
diaphragm microphones. Round capsules have a relatively low frequency
in-band resonance, typically around 1kHz. Small diaphragm mics usually have
a much higher in-band resonance, typically about 15kHz or higher. The
elliptical capsule avoids the constant distance "edge to center" of round
capsules, reduces in-band resonances dramatically, and expands the
application possibilities.
The capsule also has many conventional attributes, such as the time-tested
six-micron, gold-sputtered diaphragm used in the Bock 251 and edge
termination design. The elliptical capsule is hand-built in very small
quantities in Germany.
The 5-ZERO-7 offers many other unique features. To protect the microphone's
large body, a three-layer head grille design prevents moisture (and
therefore dirt) from becoming a continuing issue in the sound and long-term
life of the capsule and microphone. A unique, vintage 47-inspired tube mic
amplifier with very high gain was created by David Bock using his
hand-selected parts. In addition, no negative feedback or filtering is used
to affect the sound in any way. An extraordinary Bock-designed four-section
transformer, handmade in the U.S., completes the audio path.
The custom Bock power supply is designed specifically for the 5-ZERO-7 and
combines the best of the old with new and modern parts. It is a special
inductor-based design, something not seen in modern production microphones,
and offers the best combination of long-term power, low noise floor and
high-end mic sonic performance.
The large body type of the 5-ZERO-7 microphone gives artists the familiar
feel of the vintage studio mics they know and love. The fixed cardioid
characteristic of the microphone guarantees it will always be in its most
popular setting without switches and other devices that may decrease
long-term reliability. The microphone sounds very big, utilizing a carefully
crafted proximity effect for that extra-deep intimacy preferred by both
artists and engineers. This sound is expected to be especially popular on
male vocalists but is also anticipated to outperform most other mics on
females as well. There will be a wide variety of color available with
distance, increasing the mics flexibility. The 5-ZERO-7 brings something new
to voices, something unavailable in any other microphone, past or present,
at any price.
Bock Audio, established in 2007, builds the personal designs developed over
the last ten years by mic expert David Bock in Los Angeles, California.
Brad Lunde, president of TransAudio Group, said, "For years, we've been
asked to offer a mic that could compete with the best 47s and other
legendary vocal microphones. Now we have the 5-ZERO-7 that incorporates
unique designs that are technically superior. This is the best sounding
vocal mic David Bock has ever built."
US Retail Price is $6,995.
TransAudio Group, founded by industry veteran Brad Lunde, has quickly become
the premier U.S. importer/distributor and/or U.S. sales and marketing
representative for high-end audio. Success hinges on TransAudio providing
dealers and end users with a higher standard of product expertise and
support far beyond the norm.
