Austrian Audio's OC818 delivers a modern sound with impressive clarity and versatility, thanks to its multiple polar patterns and dual-output feature.

Austrian Audio's OC818 microphone delivers exceptional clarity and versatility with its multi-pattern capabilities and innovative CKR12 capsule design, reminiscent of legendary models but with modern reliability. Its robust build and thoughtful features, like a high-pass filter and pad settings, enhance its usability. However, the unique shape may limit compatibility with standard mounts, and while the internal shockmounts provide some protection, they may not suffice for all recording environments. Overall, the OC818 stands as a promising contender in the condenser mic arena, balancing vintage charm with contemporary performance—ideal for both studio and live settings, but with a few caveats.

Austrian Audio's OC818 and OC18 microphones deliver impressive sound quality with innovative design features at an attractive price point. They excel in clarity and versatility, making them suitable for various recording scenarios. However, the shockmount's design is a double-edged sword: while it's sturdy, it limits mic rotation and access to the rear output. Despite minor quirks, the OC818's dual-diaphragm and Polar Designer software offer unmatched flexibility, allowing for post-recording polar pattern adjustments. This mic is a strong contender for anyone seeking high-quality, long-lasting studio gear.

Austrian Audio OC18 and OC818 Review

musictech.com

Austrian Audio’s OC818 stands out with its innovative multi-pattern functionality and an impressive CKR12 capsule, offering versatility and professional quality at a competitive price. Its sound is clean and well-balanced, making it a formidable rival to classic models like the AKG C414. However, the OC18's brighter tonal character raises questions about its match with the OC818 when used in cardioid mode, potentially leading to inconsistencies in paired recordings. Despite this, the OC818 excels in bass applications and room tone captures, proving its worth for serious recording engineers. While not without its quirks, the overall performance is commendable, making these mics worthy contenders in any studio setup.
