Austrian Audio OC818 Dual Set Go Black Large-Diaphragm Condenser Microphone Pair

The Austrian Audio OC818 Dual Set Go Black is a professional-grade stereo pair of large-diaphragm condenser microphones engineered for high-precision studio applications. These microphones utilize the proprietary CKR12 ceramic capsule, which provides a consistent and natural sound profile across a wide frequency range. With their versatile design, these microphones allow for multiple polar patterns, making them a reliable choice for engineers and producers who require high-fidelity audio capture in demanding recording environments.

Advantages

The primary advantage of this set is the inclusion of two matched microphones that ensure phase coherence and tonal consistency when recording in stereo. The ceramic capsule design offers superior thermal stability compared to traditional brass capsules, ensuring reliable performance over time. Furthermore, the ability to switch between polar patterns provides immense flexibility, allowing users to adapt to different acoustic spaces and sound sources without needing to swap microphones. The robust construction and advanced output circuitry minimize self-noise, resulting in clean, professional recordings even in quiet settings.

Suitable for

• Stereo recording of acoustic instruments
• Drum overheads and room miking
• Vocal ensembles and choirs
• Orchestral and classical music recording
• Professional studio production and broadcast

This microphone set may not be the most suitable choice for users who require a simple plug-and-play solution for casual podcasting or basic voice-over work, as its high sensitivity and professional feature set are designed for controlled studio environments. Additionally, it is not intended for handheld use or high-SPL applications where a dynamic microphone would be more appropriate.

How to use

To use the Austrian Audio OC818 microphones, connect each unit to a high-quality microphone preamplifier using balanced XLR cables. Ensure that 48V phantom power is engaged on your interface or preamp to power the internal circuitry. Use the switches on the microphone body to select the desired polar pattern based on your recording needs. For stereo configurations, place the microphones in a standard array such as X/Y, ORTF, or spaced pair to achieve the desired stereo image. Always monitor your input levels to ensure they remain within the optimal range of your recording system.

What to consider before purchase

• Requires 48V phantom power for operation
• Requires high-quality microphone stands for stable positioning
• Best utilized in acoustically treated environments
• Requires balanced XLR inputs on your audio interface

Usage recommendations

For optimal results, ensure the microphones are placed at an appropriate distance from the sound source to capture the desired balance of direct sound and room ambience. Regularly store the microphones in their protective case to prevent dust accumulation on the capsules.
