Dynamic Mic
Robust type of microphone which picks up the sound on a diaphragm connected to a coil of wire which moves within a magnet. An alternating current is induced into the wire which provides the electrical output. Most dynamic mics have low output impedance of 200 Ohms. See Condenser Mic.

Brooks Cinema Series Impedance Matching
Having or converting the output impedance of a device so that it matches the impedance of the input it will feed.

Delay (Digital, Analogue)
1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

Brooks KM 77 Howlback
British term for the term Feedback (the pickup of the signal out of a channel by the input of the channel or the howling sound that this produces).

Full Step
A change in pitch that occurs when moving up or down two piano keys

Editing
1) Changing the sequence of a recording by cutting the recording tape and putting the pieces together in the new sequence with splicing tape.
2) Punching in and then punching out on one or more tracks of a multitrack tape recorder to replace previously recorded performances.
3) Changing the sequence of a digital recording's playback by computer program.

Infinite Baffle
A baffle so large that the sounds coming from one side do not reach the other side.
