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.
