Brooks TA 60 Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.
Cut-Off Frequency (Turnover Frequency)
1) The highest or lowest frequency in the pass band of a filter.
2) The highest or lowest frequency passed by an audio device (the cut-off frequency is usually considered to be the first frequency to be 3 dB lower than a reference frequency in the middle of the bandwidth of the device)
Brooks TM-22 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.
Link
(Said of compressors and dynamic processing units.) To combine the control input signals of two channels of a compressor (o
Brooks Cinema ZL 44 Foldback
A European term for the signal sent to the stage monitors in a live performance.
Condenser Microphone
A microphone which converts sound pressure changes into changes of capacitance. The capacitance changes are then converted into electrical voltage variations (an audio signal).
Boost
To increase gain, especially to increase gain at specific frequencies with an equalizer.
Electromagnetic Induction or Pick Up
The generation of electrical signal in a conductor moving in a magnetic field or being close to a changing magnetic field.

Brooks GT 44 FOH (Front of House)
Refers to the speakers that face toward the audience. Also called the "main" speakers.
Ground Adapter Plug
Adapts a three pronged electrical plug to a two pronged wall outlet. This bypasses the ground and may create a hum in the system. A lack of a good ground can cause mild electrical shock when touching a microphone.
Brooks Cinema Projectors Interface
Any device that allows one unit to work, drive or communicate with another unit when they cannot do so by just feeding each other often because the units are manufactured by different companies.
Hall
A large building designed for concerts; also called a concert hall.
Brooks BA 71 Kick (Kick Drum)
Another term for Bass Drum.
Electret Condenser
A condenser microphone that has a permanently polarized (charged) variable capacitor as its sound pressure level sensor.
Byte
A grouping of eight information bits.
Bouncing
Alternate name for Ping-Ponging (playing several tacks with sync playback through a console to mix them together and record them on an open track).
