Microphone Basics
24
Sound Reinforcement System: A sound system of separate components that work together to combine microphones or instruments for the purpose of amplification or recording
transducer: Converts one type of energy to another
dynamic: type of microphone that involves a diaphragm attached to a wire coil that
condenser: Type of microphone built on the principle of capacitance
phantom power: voltage that comes to the mic from the mixer through the mic cable
ribbon microphone: less known and less used mic that gets its name from thin metal ribbons placed between two poles of a permanent magnet
pickup pattern: The description of the way in which a microphone responds to sound
directionality: another name for a microphone pickup pattern
polar pattern: another name for the pickup pattern of a microphone
on axis: sound source is directly in front of the diaphragm
off axis: sound source is to the sides or rear of the microphone
omnidirectional: microphone is sensitive to sounds coming from all directions
feedback: occurs when a microphone picks up its own signals as they are played from the speakers that result in a loud squeal
cardioid: microphones that pick up sounds that are primarily on-axis
hypercardioid: design of microphone that is more pronounced version of the cardioid microphone
shotgun mic: special purpose, ultra-directional microphone
bidirectional: mics that respond equally to sounds from both the front and rear of mic, works well for picking up two singers facing each other
frequency response:measure of the output of a microphone across the range of frequencies audible to the human ear
proximity effect: causes an increase in the amplitude of the lower frequencies
transient response: refers to how quickly a mic responds to a sound as it reaches a mic
sensitivity: measure of the output of a microphone for a given sound pressure level
impedance: a measure of the microphone’s resistance to the electric current flowing from its output; measured in ohms
high impedance: a commonly used impedance microphone level ranging from 10,000 or 10K ohms
low impedance: a commonly used impedance level for microphones rated at 600 ohms
shielded cable: type of cable that prevents unwanted noise and hum added to audio signal
unbalanced cable: a cable basic circuit design that carries the microphone signal to its destination with a maximum cable length of 25 feet
balanced cable: a type of cable used for a balanced microphone that greatly reduces electromagnetic interference and allows for cables lengths of several hundred feet
contact mic: not truly a microphone that is used for acoustic instruments that respond to the vibrations in the body of the instrument
lavalier microphones: small clip-on mics that attach to a person’s clothing near their throat
wireless microphone: allows performer to move freely around stage without the limitations of being tied to a mic cable
