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

The Austrian Audio OC818 Dual Set Go Silver is a professional-grade stereo pair of large-diaphragm condenser microphones engineered for high-precision studio applications. These microphones feature a proprietary CKR12 ceramic capsule design, which ensures exceptional sound transparency and a natural frequency response. With their versatile polar pattern control and robust construction, these microphones are designed to meet the rigorous demands of professional recording engineers and producers seeking reliable, high-fidelity audio capture.

Advantages

The primary advantage of this dual set lies in the precision matching of the two microphones, ensuring consistent phase response and stereo imaging for critical recording tasks. The inclusion of multiple polar patterns allows for significant flexibility in various acoustic environments, enabling users to switch between cardioid, omnidirectional, figure-eight, and supercardioid settings. Furthermore, the microphones offer advanced features such as dual outputs, which allow for independent recording of both capsules, providing the ability to adjust the polar pattern during post-production. The build quality is designed for long-term durability, making it a dependable investment for any studio setup.

Suitable for

• Recording acoustic instruments such as guitars, pianos, and strings
• Capturing professional vocal performances
• Creating complex stereo soundscapes and ambient recordings
• Drum overhead miking and ensemble recording

This microphone set may not be suitable for users requiring a simple plug-and-play solution for casual podcasting or basic voice-over work, as its advanced features and professional sensitivity require a dedicated audio interface with phantom power and a controlled acoustic environment to achieve optimal results. It is also not intended for high-SPL live sound reinforcement where rugged, dynamic microphones might be more appropriate.

Key specifications

• Transducer type: Large-diaphragm condenser
• Polar patterns: Cardioid, omnidirectional, figure-eight, supercardioid, and custom
• Frequency range: 20 Hz to 20 kHz
• Sensitivity: 13 mV/Pa
• Maximum SPL: 148 dB
• Output impedance: 275 ohms
• Power requirements: 48V phantom power

To use the Austrian Audio OC818 microphones, connect each unit to a high-quality microphone preamplifier or audio interface using balanced XLR cables. Ensure that 48V phantom power is engaged on your interface for the microphones to function. Position the microphones according to your desired stereo technique, such as X/Y, ORTF, or spaced pair, to achieve the intended soundstage. If utilizing the dual-output feature, connect both outputs to separate preamp channels to enable post-production polar pattern adjustment via compatible software.

What to consider before purchase

• Ensure your audio interface provides stable 48V phantom power
• Verify that your studio space is acoustically treated to handle the high sensitivity of these microphones
• Consider the need for additional high-quality XLR cables and sturdy microphone stands

For the best results, always store the microphones in their protective cases when not in use to prevent dust accumulation on the capsules. Use high-quality pop filters for vocal recordings to protect the diaphragm from moisture and plosives.
