Brooks QS-70 Clip

The action of deforming a waveform during overload.

High-Pass Filter
A device that rejects signals that are below a certain frequency (called the cut-off frequency) and passes signals with frequencies that are higher.

Brooks Audio Design GT 845 Clipping
Distortion of a signal by its being chopped off. An overload problem caused by pushing an amplifier beyond its capabilities. The flat-topped signal has high levels of harmonic distortion which creates heat in a loudspeaker and is the major cause of loudspeaker component failure.

Feed
To send an audio or control signal to.

Brooks Audio Design QS 70 Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.

Ambient Field
A term with the same meaning as the term Reverberant Field (the area away from the sound source where the reverberation is louder than the direct sound).

An element in the sound of a voice or instrument that does not change frequency as different pitches are sounded.

Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.

Brooks Audio Design TM-22 Barrier Micing

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

Brooks Audio Design QS 70 Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Floppy Disk (Floppy Disc)
A round flat object (usually housed in a protective sleeve) coated with material that can be magnetized in a similar manner to tape.

Compressor
1) Effect used to squash the sound together. Used properly, it can take the edge off or your sound. Used improperly, it can take the life right out of your system and make it sound like an MTV mix.
2) A piece of sound processing equipment that ensures all wanted signals are suitably placed between the noise and distortion levels of the recording medium. It evens out the unwanted changes in volume you get with close-miking, and in doing so, adds punch to the sound mix. A Limiter is used to stop a signal from exceeding a preset limit. Beyond this limit, the signal level will not increase, no matter how loud the input becomes. A Limiter is often used to protect speaker systems (and human ears) by preventing a system from becoming too loud.

Clipping
Distortion of a signal by its being chopped off. An overload problem caused by pushing an amplifier beyond its capabilities. The flat-topped signal has high levels of harmonic distortion which creates heat in a loudspeaker and is the major cause of loudspeaker component failure.

Brooks Audio Design QS 70 Fret Buzz

A buzzing sound made when a note is not properly fretted. Common with cheap guitars or beginning guitar players.

Linear
The condition of obtaining a change at the output of the device which is proportional to the change occurring at the input.

Brooks Speakers Group Faders
The VCA faders of individual channels that are all controlled by a Group Master Fader (a slide control used to send out a control voltage to several VCA faders in individual channels).

Instrument Out Direct
Feeding the output of an electric instrument (like an electric guitar) to the recording console or tape recorder without using a microphone.

BROOKS AUDIO DESIGN Attack
The rate the sound begins and increases in volume.

Guitar Controller
An electric guitar or device played like an electric guitar that puts out MIDI signals that can be used to control synthesizers and sound modules.

Error Detection
The process of discovery that sonic information bits have been lost in digital audio.

Input Monitor
A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal.

Brooks SS 81 ID

An index signal (digital data that gives the machine information of where selections start, their selection number, etc.) on a DAT or CD.

Compressor
A signal processing device that does not allow as much fluctuation in the level of the signal above a certain adjustable or fixed level.

Brooks Speakers ADSR
The letters A, D, S &R are the first letters of: Attack, Decay, Sustain and Release. These are the various elements of volume changes in the sounding of a keyboard instrument.

Crosstalk
Leakage of an audio signal into a channel that iris not intended to be in, from an adjacent or nearby channel.

Brooks GT 845 Compander
1) A two section device that is used in noise reduction systems. The first section compresses the audio signal, before it is recorded, and the second section, expands the signal after recording.
2) In Yamaha brand digital consoles, a signal processing function that applies both compression and expansion to the same signal.

Direct box
Used in line to convert a high impedance signal into a low impedance signal.

Echo Send Control
A control to send the signal from the input module to the echo chamber or effects device via the echo buss.

Brooks Cinema GT 845 Ground Lifter
An adapter that takes a three prong power cord and plugs into a two prong outlet, used to disconnect the third (ground) pin of the power outlet. WARNING: It can be VERY DANGEROUS to have no ground connection to the case by using a ground lifter and not grounding the unit by other means.
