Sound/Electroacoustics
What is sound?
These microphones are the most sensitive type of microphone. They are known for their quick transient response, wide frequency range, and their need of 48v phantom power.
What are condenser mics?
44.1 kHz/16 Bit
What is CD Quality?
What are inserting and send/return?
In a live setting, what simple phrase should an audio technician be prepared to say to the performer after their set?
What is "great set"?
When considering the acoustics of an environment, most surfaces can be put into one of these three categories.
What are reflection, absorption, and diffusion?
This phenomenon, found only in directional mics, results in a boost in low end response when as a microphone approaches a sound source source.
What is proximity effect?
An audio path used to combine various signals or inputs for a common destination.
What is a bus?
When setting up an effects up, the processor's wet/dry setting should be set to this.
100% Wet.
This type of EQ is used to tune systems and combat feedback.
What is graphic EQ?
These features are sometimes found on condenser microphones.
What are PAD, High Pass, and Polar Pattern?
These are the three main sections of a mixer.
What are channels, master, and monitor?
Limiting and gating are extreme forms of these two types of processors.
Compressors and expanders.
Bill Putnum iconically used this room in the studio to create the first known artificial reverb on a recording.
What is the bathroom?
"Peg o' My Heart" by the Harmonicats in 1947.
This electrical concept should be considered when matching speakers to amps, daisy-chaining speakers, and when interfacing instruments or instrument amplifiers with other audio equipment. When used for lower voltages, it is sometimes referred to as "z".
What is "impedance"?
What is "electromagnetism"?
This type of digital file compression is known for a loss in quality, such as MP3.
What is Lossy file compression?
A fully parametric EQ is defined by the presence of these three features being adjustable.
What are frequency, gain, and bandwidth?
In the past, this effect was usually an unintended consequence of the limited operating ranges of equipment. Today it is almost necessary to add when mixing a digital recording, for its increase in harmonic content and perceived volume to a source or mix.
What is "saturation" or "distortion"?
What is:
1. Mic (millivolts)
2. Line (~volts)
3. Speaker (many volts)
4. Instrument (between mic and line)
What is frequency response?
These are the two types of auxiliary sends and their general uses.
What are pre-fader used for monitoring and post-fader used for effects?
When confronted with new gear, these are two important approaches to educating yourself.
What are "googling" and "RTFM"?
