OC7 True Condenser Instrumental Microphone [] Austrian Audio [] Sound Technology Ltd

Overview

Austrian Audio proudly introduces the OC7 true condenser microphone, optimised for use on instruments. The mic is handmade in Vienna and subjected to the strictest quality assurance processes. The OC7 features the OCC7 small diaphragm capsule, also handmade in Vienna. As to be expected from Austrian Audio, this mic comes with some special features:

Most noticeable is the "Swivel Joint" mechanism. Musicians and sound techs are familiar with the problem of microphone stands that are screwed on too tightly and can hardly be reached in the forest of stands on stage. Once you finally get them loose, they lose their position completely - making fine adjustments to microphone angles by a few degrees difficult.

Austrian Audio's engineers have developed a swivel system for the microphone basket that allows a 220° rotation of the field. The microphone can be very easily aligned precisely to the sound source or according to personal sound preferences without having to awkwardly adjust or loosen the microphone stand; frustrations such as microphones falling off or fingers pinched on the stand are now a thing of the past.

Precise directionality is a prerequisite for the targeted alignment of a microphone. The OC7 uses Austrian Audio's well-known Open Acoustics technology: the "linear cardioid" polar pattern captures sound not only from the front, but also from the rear or side, perfectly and undistorted. This ensures that even the, sometimes unavoidable, crosstalk from other instruments sounds good.

The OC7’s true condenser capsule is perfectly protected by the microphone basket and can therefore be positioned without hesitation even in places where the microphone might be subjected to knocks. The OC7 is equipped with a 2nd order high-pass filter with an operating frequency of 40 or 80Hz. A -10dB pad, which results in lower sensitivity by reducing the capsule voltage, allows it to be used in front of the loudest sound sources. With an outstanding 154 dB SPL (>160dB SPL with pad), the OC7 is extremely resistant to overload.

The OC7 impresses with an open and transparent sound reproduction and, due to the strengths of the OCC7 small diaphragm capsule, it is ideally-suited for use on all instruments that have particularly lively transients. This includes all kinds of percussion instruments including snare drums and toms, but also piano and acoustic guitar. The open, silky sound also lends itself to use on various string instruments.
