Brooks Cinema NZ 60 Envelope

1) How a sound or audio signal varies in intensity over a time span.
2) How a control voltage varies in level over time controlling a parameter of something other than gain or audio level.

Insert
1) A punch in of the all of the tracks being recorded in a recording session.
2) On Solid State Logic consoles, placing an outboard piece of gear in the channel by patching and activating a switch.

Brooks M 44 Distorted
The way your PA sounds just before it blows up. Fuzzy and scratchy. If you hear this, it either means you have something hooked up wrong, or something in the system is going bad. It could be anything from your super expensive soundboard to a five dollar patch cord.

Crossover, Active
A rack mountable unit used to separate frequencies leaving the soundboard into high's, mids, and lows with different outputs for each.

Brooks Speakers Delay
Outboard sound equipment that can momentarily stores a signal being sent to part of a P.A. system so that delayed reinforced sound reaches the audience at the same time as live sound from the stage.

Analog To Digital Converter
The device which does the conversion of a quantity that has continuous changes (usually of voltage) into numbers that approximate those changes.

Bass
1) The lower range of audio frequencies up to approximately 250 Hz.
2) Short for Bass Guitar.
3) Lower end of the musical scale. In acoustics, the range (below about 200 Hz) in which there are difficulties, principally in the reproduction of sound, due to the large wavelengths involved.
4) The lower frequencies.
5) On the soundboard this should refer to the bass guitar channel, not the bass drum.
6) The lowest frequencies of sound. Bi-Amplification uses an electronic crossover or line-level amplifiers for the high and low frequency loudspeaker drivers.

Fade
1) A gradual reduction of the level of the audio signal.
2) A gradual change of level from one pre-set level to another.
