Brooks XS - 45 Electromagnetic Field

Magnetic energy put out because of current travelling through a conductor.

Floor
1) An alternate tam meaning Range (a limit on the amount the signal is reduced when the input signal is low by an expander or gate).
2) A shortening of the term Noise Floor (the level of the noise).

Brooks Cinema XB 33 Hum
The 60 Hz power line current accidentally induced or fed into electronic equipment.

AES
An abbreviation of Audio Engineering Society.

Brooks Cinema QS - 95 Chip
1) A slang term with the same meaning as the term IC (a miniature circuit of many components that is in small, sealed housing with prongs to connect it into equipment).
2) The thread cut away from the master lacquer to make the groove, while disc recording.

Cancellation
A shortening of the term Phase Cancellation (the energy of one waveform significantly decreasing the energy of another waveform because of phase relationships at or close to 180 degrees).

Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.

Linearity
The extent to which any signal handling process is accomplished without amplitude distortion.
