4. Operating the Microphone

The RK-87 is designed to restore the essence of sound to the greatest extent, providing a relatively bright sound. It is ideal for capturing vocals and instruments with clarity and detail.

4.1 Optimal Placement

Experiment with microphone placement relative to the sound source to achieve the desired tonal characteristics. For vocals, a distance of 6-12 inches is often a good starting point. For instruments, consider the instrument's natural sound projection.

4.2 Gain Staging

Adjust the gain on your audio interface to ensure a strong signal without clipping. The RK-87 has a maximum sound pressure level of 140dB (at 1KHz≤1% T.H.D), allowing it to handle loud sources.
