The Shure SM86 is a Cardioid Condenser Vocal Mic. This mic gives you all the advantages of Shure's SM line with condenser mic clarity. It's ruggedly built to handle touring, with a frequency response tailored for clear reproduction of vocals. The cardioid polar pattern minimizes background noise and feedback. The SM86 has a built-in 3-point shock mount for minimizing handling noise and a 2-stage filter for reducing breath noises and pops. It requires phantom power. The SM86 requires phantom power. This may be supplied to the microphone from an external power supply (such as the Shure model PS1A) or directly from preamplifiers, mixers, or consoles with built-in phantom power. Suitable sources should provide 11 to 52 Vdc phantom voltage.
General Rules for Use
- Do not cover any part of the microphone grille with your hand, as this will adversely affect microphone performance.
- Aim the microphone toward the desired sound source (such as the talker, singer, or instrument) and away from unwanted sources.
- Place the microphone as close as practical to the desired sound source.
- Work close to the microphone for extra bass response.
- Use only one microphone to pick up a single sound source.
- For better gain before feedback, use fewer microphones.
- Keep the distance between microphones at least three times the distance from each microphone to its source (“three to one rule”).
- Place microphones as far as possible from reflective surfaces.
- Add a windscreen when using the microphone outdoors.
- Avoid excessive handling to minimize pickup of mechanical noise and vibration
