Incorporating the same elegant swivel system as Austrian Audio’s OD5 Active Dynamic instrument microphone, the OC7 offers a unique small diaphragm condenser mic design.
Handmade in Vienna under strict quality control conditions, the OC7 is the latest model to incorporate the manufacturer’s state-of-the-art OCC7 condenser capsule. The technology underpinning the diaphragm inside the OCC7 is much more robust than conventional alternatives, allowing it to withstand extremely high sound pressure levels whilst also delivering an impressively linear frequency response. This results in a natural and open sound, even at extreme volumes.
The strengths of the OCC7 capsule make it well-suited for use on instruments that produce particularly strong transients. This includes the majority of percussion instruments, but also piano, acoustic guitar and much more. The capsule’s ability to render silky mids and highs also help the OC7 to excel on various string instruments.
The OC7 includes a switchable HPF featuring an 40 Hz and 80 Hz mode and as with the OD5, a -10dB pad can also be toggled. When engaged, the pad on the OC7 results in lower mic sensitivity by reducing the capsule voltage. This allows for an outstanding max SPL of more than 160dB, making the OC7 extremely resistant to overload.
As directionality plays a major role in achieving desirable instrument sound, Austrian Audio’s engineers have incorporated the same swivel technology from the OD5 into the new OC7. This suspension system allows for a 220° rotation of the outer capsule basket. This rotation enables precise alignment of the capsule to the sound source, without the need to adjust or loosen the microphone stand.
The OC7’s swivel mechanism serves to eliminate common frustrations in microphone placement, such as struggling with tightening/loosening microphone stand nuts when only a small change in angle is required, or the loss of microphone position altogether when loosening. Austrian Audio’s now well-established Open Acoustics technology has also been incorporated into the OC7, with both the capsule suspension and microphone basket designed to avoid acoustic interference. The Open Acoustics approach also allows for sound from the rear to pass through to the inner capsule. This results in the formation of a highly accurate cardioid characteristic, which the manufacturer has dubbed ‘Linear Cardioid’. The end result of this design is a clean, natural and precise sound.
