Austrian Audio OC818 Dual Set Plus Large-Diaphragm Condenser Microphone Pair

The Austrian Audio OC818 Dual Set Plus is a professional-grade large-diaphragm condenser microphone pair engineered for high-fidelity studio applications. These microphones utilize the proprietary CKR12 ceramic capsule, which provides a natural and transparent sound profile. With switchable polar patterns and advanced output technology, this set is designed to meet the rigorous demands of professional recording engineers, offering precise control over stereo imaging and sound source capture.

Advantages

The primary advantage of the OC818 Dual Set Plus lies in its exceptional versatility and sonic accuracy. The inclusion of two matched microphones allows for sophisticated stereo techniques such as X/Y, ORTF, or Mid-Side configurations with perfect phase coherence. The microphones feature a unique open-acoustic design that minimizes internal reflections, resulting in a clean and detailed frequency response. Furthermore, the ability to record the rear capsule output independently allows for post-production polar pattern adjustment, providing unparalleled flexibility during the mixing process.

Suitable for

• Stereo recording of acoustic instruments and ensembles
• Professional vocal tracking
• Drum overhead and room microphone applications
• Mid-Side stereo recording techniques
• Orchestral and choral recording

When it may not be suitable

This microphone pair may not be the ideal choice for budget-conscious home studio setups where the cost of high-end professional equipment is not justified. Additionally, due to their high sensitivity and precision, these microphones require a controlled acoustic environment to perform at their best, making them less suitable for untreated rooms with significant background noise.

Key specifications

• Transducer type: Large-diaphragm condenser
• Capsule: Hand-made CKR12 ceramic capsule
• Polar patterns: Omnidirectional, cardioid, supercardioid, figure-eight, and programmable
• Frequency range: 20 Hz to 20 kHz
• Sensitivity: 13 mV/Pa
• Maximum SPL: 148 dB
• Output impedance: 275 ohms

How to use

To use the OC818 microphones, connect them to a high-quality audio interface or microphone preamplifier using balanced XLR cables. Ensure that 48V phantom power is engaged on your preamplifier to power the internal electronics. For stereo applications, position the microphones according to your desired stereo technique, ensuring they are mounted securely on stable microphone stands. If utilizing the dual-output feature for post-production pattern control, connect the secondary output to a separate input channel on your interface and use the dedicated software plugin to adjust the polar pattern after the recording session.

What to consider before purchase

• Ensure your audio interface has sufficient high-quality preamplifier inputs to support stereo recording.
• Verify that your studio environment is adequately treated to take advantage of the high sensitivity of these microphones.
• Consider the need for additional high-quality XLR cables and sturdy microphone stands for stereo mounting.

Usage recommendations

For optimal results, always use the included shock mounts to prevent low-frequency vibrations from affecting your recordings. When storing the microphones, keep them in the provided protective case to prevent dust accumulation on the delicate ceramic capsules.
