This reduction provides a mic frequency balance when working close to the mic, but if the mic is used at a greater distance than it was designed for it may sound harsh since it will not have enough bass response. A few vocal mics have a bass cut switch which can restore low end response so the mic can be used for instruments. Many vocal microphones have a presence peak, which is a high frequency peak between 8000Hz and 10000Hz. This boost adds clarity and articulation to most voices and can compensate for poor sound system performance. Most of the higher priced dynamic and condenser vocal microphones have a less dramatic or no high frequency peak since they were intended to be used with higher quality sound systems.
Most vocal microphones are cardioid, which means that they have minimum pickup at the rear.
Hypercardioid and Supercardioid mics have even less sensitivity at the sides, but do have a small pickup lump at the rear which the cardioids do not have, so are more critical in placement in regard to floor monitors. Benefits gained as price increases are reduced handling noise, smoother response off-axis which reduces feedback problems, and more consistent response from one mic to the next. Most vocal microphones are dynamic with traditional alnico magnets, some feature the new neodymium magnets which increase output level, reduce suspended mass and which allow better acoustic designs. Condenser elements are used in some models, they have lower distortion and better transient response, but do need either battery or phantom power. Nearly all models include a stand clip in the price.
