Bock Audio 507

The Bock Audio 507 (5-ZERO-7) is a high quality cardioid directivity studio condenser microphone utilizing vacuum tube electronics and a unique elliptical capsule.

The Bock 5-ZERO-7 is a new approach in high end microphone design for it combines new and old: a brand new unique and patent pending elliptical capsule married to a vintage inspired mic amplifier and power supply. Designed to be the ultimate in studio vocal microphones, the 5-ZERO-7 compares favorably to the best vocal microphones, past and present.
Features
HOW TO USE THE 5-ZERO-7
The 5-ZERO-7 microphone itself is a large body type, to give singers and artists a familiar feel in the studio to vintage mics they know and love. The fixed cardioid nature of the microphone guarantees it will always be in its most popular setting without switches and other devices to decrease long term reliability. The microphone sounds very big, utilizing a carefully crafted proximity effect for that extra deep intimacy preferred by artists and engineers alike. This sound is expected to be especially popular on male vocalists but will be expected to outperform most other mics on females as well. There will be a wide variety of color available with distance, so this will increase it's flexibility. You will find that the 5-ZERO-7 brings something new to voices, something unavailable in any other microphone, past or present, at any price.

WHAT MAKES IT DIFFERENT
The new Bock/Cardas elliptical capsule design 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 1K. Small diaphragm mics usually have a much higher in band resonance, typically about 15K or higher. The elliptical capsule offers the best of both, avoiding the constant distance "edge to center" of round capsules, reducing in band resonances dramatically and expanding the application possibilities. The ZERO capsule also has many conventional attributes such as the time tested 6 micron gold sputtered diaphragm used in the BOCK 251 and edge termination design. The capsule is hand built in very small quantities in Germany.

The 5-ZERO-7 also offers many other unique features. A large body microphone, it uses a 3 layer headgrille to prevent moisture (and therefore dirt) from becoming a continuing issue in the sound and long term life of the capsule and microphone. A unique tube mic amplifier was designed of very high gain, vintage 47 inspired, with David Bock hand selected parts. No negative feedback or filtering is used in this microphone to affect sound in any way. An extraordinary US handmade BOCK design four section transformer is employed to complete the audio path.

The custom BOCK power supply is designed just for this microphone 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 today. It offers the best combination of long term power, low noise floor and high end mic sonic performance.


The Bock/Cardas Elliptical capsule can be fine tuned to more specific applications such as orchestra, etc.
