MICROPHONES

The microphone is the first connection with the chain of recording sound equipment in almost any situation, so the different types of microphones divide into basically 4 catagories , Condenser, Dynamic, Pressure zone and Ribbon.

Only the first one requires an external source of power from batteries or mains, the other option is “Phantom power “ which delivers 48 volts from the mixing desk or other external source.

A general rule of thumb would be to use a microphone that responds to frequencies higher than you actually need , this will help to keep the higher notes clear and allow the treble to cut through.

A microphone that only covers the low end frequencies will not be suitable for most applications but also be aware that bass frequencies from other sources can be detected so a microphone that has a bass cut off switch can be very useful, so try to get the right microphone for the right job ,be it percussion items such as Bongos, Timbales, Tambourines and Chimes on the upper frequencies and on drum kits with splash and china cymbals, octobans forming the upper end  ,and 18” floor toms and bass drums will require low impedance with compression on it which range from 30 ohms to 600 ohms.

The most commonly used impedance is about 200 ohms which is a compromise between 30 and 600ohms

the high impedance microphone’s performance will be affected when cables longer than about 10ft or 3 metres are used which makes them unsuitable for most studio applications.

The closer the microphone to the bongo, snare drum or guitar etc and the speaker the more likely you are to get feedback, which is simply the microphone picking up its own signal.

So pick wisely for the microphone to suit your needs.
