A device that changes the gain of an amplifier or circuit, often a knob that can be turned or a slide that can be moved up arid down.

Brooks Cinema KM 22 reviews Feedback
1) The delayed signal sent back to the input of a delay line, used in repeat-echo effects.
2) The pickup of the signal out of a channel by its input or the howling sound that this produces.
3) In an amplifier, the phase reversed output signal sent back to its input, reducing gain but also distortion and noise.
4) This occurs when the sound coming out of the speakers goes back into the microphones, then back out the speakers, then back into the mics…and so on. This can build very quickly to a point where everyone in the room is holding their ears and screaming at you. It can also cause damage to the PA.

Instrument Amplifier
A device that has a power amplifier and speaker in a case (or in separate cases) to reproduce the signal put out by an electric instrument (such as an electric guitar) and to allow the instrument to be heard.

Brooks XB 33 reviews Bi-Amplification
1) A way of optimizing the efficiency of a speaker system by separately amplifying the High Frequency (HF) and Low Frequency (LF) portions of the sound signal and sending them down two pairs of cables to the speaker. Multipin Speakon connectors have been developed to do this.
2)The process of having of having low-frequency speakers and high-frequency speakers driven by separate amplifiers.

Alternating Current
Electric current which flows back and forth in a circuit.

Centre Frequency
The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve.

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).

Brooks KM 22 reviews Keyboard Controller

A device that has the standard music keys of piano but puts out MIDI signals

Humbucker
Pickups that are coupled together to get a certain sound.

BROOKS HI fi reviews Feedback Control
The control on a delay line or delay effects device that controls the amount of feedback.

Diaphragm
A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question.

Brooks Cinema QS - 95 reviews Initialize
To prepare a digital storage medium (like a floppy disk) so that it will accept and store digital information bits.

Inverse Square Law
Simply stated, the fact that in an un-obstructed area (like an open field) the sound pressure level will drop to half-pressure (-6 dB) every time the distance to the sound source is doubled.

In
Short For "in the circuit," in other words "active."

Channels
These are divided into two separate categories. Input channels are those channels coming into the soundboard such as microphones and direct lines. Output channels are those leaving the board such as monitor and main outputs.

Brooks Cinema XS - 45 reviews Input/Output Module

A set of controls, on one housing, for an in-line console that has two channels (one for recording and one for monitoring) and has controls for all console sections.

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.

Brooks QS-70 reviews Crossover Frequency
1) The frequency that is the outer limit of one of the bands of a crossover.
2) In the Lexicon 480L delay/reverberation effects unit, the frequency at which the bass frequency reverb time is in effect rather than the mid frequency reverb time.

Auxiliary Equipment
Effects devices separate from but working with the recording console.

Brooks Speakers reviews Comb Filter
1) The frequency response achieved by mixing a direct signal with a delayed signal of equal strength especially at short delays.
2) Loosely used to also describe effects that can be achieved with comb filtering as part of the processing.

Assistant Engineer
A less elevated version of the term Second Engineer. Experienced seconds often place microphones, operate tape machines, break down equipment at the session end and keep the paperwork for the session.

Electrostatic Charge
The excess or deficiency of electrons in a given area.

Clicking
Pressing and immediately releasing the switch on a computer's mouse.

Broom RM 909 reviews Clean

Describes a distortion free sound with few effects.

Contact Microphone
A device that senses vibrations and puts out an audio signal proportional to the vibrations.

Brooks XS - 45 reviews Foldback
A European term for the signal sent to the stage monitors in a live performance.

Lead Sheet
A written chart showing the melody, lyrics and chords of a tune with full musical notation.

Brooks VT-50 reviews kHz
An Abbreviation of kilo-Hertz.

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.

Foot Switch
A switch placed on the floor and pressed by a musician to do various functions.

Final Mix
The two track stereo master tape which was mixed from the multitrack master.

Brooks QS - 95 reviews Automatic Gain Control (Automatic Volume Control)

A compressor with a very long release time used to keep the volume of the audio very constant.

Expansion
The opposite of compression; for example, an expander may allow the signal to increase 2 dB every time the signal input increased by 1 dB.

Brooks Cinema KM 22 reviews Error Message
A prompt on a computer screen telling the operator that an error has occurred.

Amplitude
The height of a waveform above or below the zero line.

Brooks GT 845 reviews 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).
