Sound Science
This objective measurement references the number of waves that occur over a period of time. Subjectively, humans refer to it as "pitch."
What is frequency?
Microphones are these components, which converts acoustic energy into electrical energy.
What is an input transducer?
Frequency is measured and Hertz, and this range of frequency is the range of human hearing capabilities.
What is 20Hz to 20kHz?
Often one of the first components in a console's signal flow, this adds amplification to a mic-level signal.
What is a pre-amp?
This switch on a console will cause the signal to invert over a zero line, but does not use delay shift.
What is polarity reverse?
This type of directional microphone accepts sound from 0º and 180º, and includes two separate diaphragms.
What is a bidirectional microphone?
According to the Fletcher-Munson curve, this frequency group is more prominent when listening at lower volume levels.
What are the mids?
This type of bus setup is used to apply time-based effects so that the user can include a mix of the dry signal AND the wet signal.
What are FX sends/returns?
When two matching frequencies are played 180º out of phase, this occurs.
What is cancellation?
This type of transducer has a thin sheet of metal suspended between magnets, and should not be sent phantom power.
What is a ribbon microphone?
This style of EQ has a set bandwidth, and uses faders to cut or boost a large variety of frequencies.
What is a graphic EQ?
This parameter on an input channel allows the user to make space in the frequency and stereo field by mixing the signal Left or Right.
What is the pan/pan pot?
Constructive interference causes the amplitude of a frequency (or group of frequencies) to do this.
What is increase?
This transducer type requires an external power source for an additional stage of amplification at mic-level, and is sensitive to high SPLs.
What is a condenser?
This device is used to attenuate a signal that is entering the console at a higher-than-optimal level.
What is a pad?
This type of console set-up is useful for situations where only one fader is available for both input level and monitoring.
What is a split console set-up?
