The Austrian Audio OC7:

• Small diaphragm condenser microphone
• Open and transparent sound
  
• Best suited for instruments that have particularly lively transients, such as Percussion & drums, piano, acoustic guitar or string instruments
  
• Well protected capsule - can be prositioned without problems even in "dangerous" places
  
• Even rear sound can penetrate to the capsule (Open Acoustics technology)
  
• Therefore precise and coloration-free cardioid characteristic
  
• Lateral and rear "bleeding" is reproduced without coloration
  
• 220° rotatable microphone holder with proprietary "Swivel-Joint" mechanism
  
• No more annoying alignment problems with microphone stands
  
• With switchable low-cut (40Hz & 80Hz) and -10dB pad
  
• Developed and manufactured in Vienna

What are the possible applications of the OC7?

The OC7 from Austrian Audio is a condenser microphone with a small diaphragm capsule and features a two-stage switchable low-cut and a -10dB pad.
With up to 160dB SPL cutoff sound pressure level (with pad on), it is as overdrive-free as a condenser microphone can be, making it suitable even for loud sources such as drums and percussion. Due to the hand-made OCC7 small-diaphragm capsule, it is ideally suited for instruments with lively transients. This includes all kinds of percussion instruments including snare and toms, but also piano and acoustic guitar. In addition, its open and silky sound is also an excellent match for string instruments
.

Why is the OC7 open at the back?

Thanks to "Open Acoustics" technology, sound from the rear can also pass through to the capsule, resulting in an extremely precise cardioid characteristic. This "linear cardioid" means that sound coming in not only from the front, but also from the rear or the side sounds good and undistorted. As a result, even the sometimes unavoidable crosstalk from other instruments sounds good.

What does the "Swivel-Joint" mechanism do?

Sound engineers and musicians know the problem of microphone stands that are screwed on too tightly and can hardly be reached in the forest of stands. When you finally loosen them, they lose their position completely - and that's just because you wanted to change the microphone angle by a few degrees. To make positioning the OC7 easier, the microphone suspension allows 220° rotation. This allows the microphone to be precisely aligned to the sound source, respectively, according to personal sound preferences, without having to awkwardly adjust or loosen the microphone stand. Various annoyances such as microphones falling over or fingers jammed on the microphone stand are now a thing of the past.
