OC818

Large-diaphragm Condenser Microphone with Multiple Polar Patterns

THE ALL NEW
POWERHOUSE

The new
viennese original

Engineered and manufactured in Austria, The OC818 is Austrian Audio’s premier, professional, large diaphragm microphone. Its high sensitivity, low self-noise and ability to handle everything from a whisper to extreme SPLs make it the most advanced microphone for studio, broadcast and live applications. As the unique ceramic capsule design is so consistent, any OC818 is match-paired with any other OC818, and when in cardioid mode, it can also be match-paired with any OC18, its affordable, smaller sibling.

Reviews

Austrian Audio have brought to market a top-class mic at a very tempting price.
Sound On Sound Gear Of The Year 2019
Austrian Audio ist es gelungen, die Wiener Tradition nicht nur wiederzubeleben, sondern auch um zukunftsweisende Technologien zu erweitern.
Sound & Recording 09-10 2019
These microphones perform superbly on almost all instruments and voices. Their even-handed nature and freedom from unwanted resonance makes them brilliant all-rounders in most situations
MusicTech OC818/18
Das OC18 hat schon ordentlich vorgelegt, aber was Austrian Audio mit dem OC818 zum Preis von knapp unter 1000,- Euro bietet, ist herausragend.
amazona.de OC818 Review
This is a reference grade studio mic that stands on its sound quality, but also offers features that will soon become indispensable parts of our studio workflow.
Audio Media International OC818 Review
Das Austrian Audio OC818 ist ein durch und durch gelungenes Mikrofon, das klanglich und vom Handling her eine wirklich gute Figur abgibt.
Bonedo OC818 Review
The OC18 and OC818 aren’t just great microphones for the price: they’re great microphones, full stop.
SoundOnSound Magazine 07/2019
This is a mic where there’s no point in highlighting sources- the OC818 loves them all, from delicate strings to rocking guitar cabinets, to drum overheads and piano. It’s also lovely on vocals
Recording Magazine (USA) 10/2019
The OC818 is one of the best-sounding new microphones I’ve had the pleasure of reviewing over the past 15 years
Audio Technology 9/2019
The OC18 is more than a microphone. It is a statement. A statement that puts Austrian Audio on the map
