Austrian Audio OC18

The Austrian Audio OC18 is a precision cardioid microphone that delivers the same sonic signature as the flagship OC818. It utilizes the identical handmade CKR12 ceramic capsule, ensuring a classic, rich sound with pristine accuracy. Designed as a "pure" microphone, it strips away the digital control features to focus entirely on high-quality cardioid recording. The OC18 is rigorously calibrated, meaning any two OC18s (or an OC18 and an OC818) form a matched pair right out of the box.

Key Features:

• Same Sound as OC818: Identical CKR12 capsule and acoustic path.
• Precision Cardioid: Optimized for vocals and acoustic instruments.
• Matched Pair: Production tolerance so low any two mics match.
• No Compromise: Metal housing and high-headroom electronics.

Technical Specs:

• Polar Pattern: Cardioid
• Frequency Range: 20 Hz – 20 kHz
• Self-Noise: 9 dB SPL (A)
• Max SPL: 148 dB
