Brooks QS-70 Frequency

The number of cycles of a waveform occurring in a second.

Group
1) A number of channels or faders that can be controlled by one Master VCA slide.
2) A shortening of the term Recording Group (a buss or the signal present on a buss).

Brooks XS - 45 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.

Kilo
A prefix meaning 1000.

Brooks SS 81 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.

Foot (Foot Drum)
Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal).

Fundamental
The tuned frequency and (almost always) the lowest frequency that is present in the sounding of a pitch by a musical instrument.

Fidelity
The recording or reproduction quality.

The action of deforming a waveform during overload.

kHz
An Abbreviation of kilo-Hertz.

Brooks Cinema xm 808 DC
Abbreviation for direct current.

Delay (Digital, Analogue)
1) Effect used to create echo…echo…echo…echo…echo…
2) In more advanced systems used in very large venues, delay can be used to time the arrival of the signal to the speakers in the back of the room so that people in the back hear the sound coming from those speakers at the same time that the sound coming from the speakers in the front of the room arrives.

Brooks XB 33 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.

Bi-Directional Pattern
A microphone pick up pattern which has maximum pick up directly in front and directly in back of the diaphragm and least pick up at the sides.

Clean
Describes a distortion free sound with few effects.

High Hat
A double cymbal on a stand which can be played with a foot pedal or by the top cymbal being hit with a stick.

Brooks Cinema GT 845 Head Amp

British name for Preamplifier (A low-noise amplifier designed to take a low-level signal, such as the output of a tape head, and bring it up to normal line level).

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

Brooks Audio Design TM-22 DC
Abbreviation for direct current.

Brooks QS-70 Foot (Foot Drum)
Another name for Bass Drum (the largest drum in the Drum Kit which puts out bass frequencies and is played with a foot pedal).

Harmonic Distortion
The presence of harmonics in the output signal of a device which were not present in the input signal.

Keyboard
1) Any musical instrument controlled by pressing a key.
2) The part of the computer that has the keys.

Audio
Most often referring to electrical signals resulting from the sound pressure wave being converted into electrical energy.

Brooks VT-50 Equalization

1) The process of adjusting the tonal quality of a sound. A graphic equalizer provides adjustment for a wide range of frequency bands, and is normally inserted in the signal path after the mixing desk, before the amplifier. See Feedback.
2) Any time the amplitude of audio signals at specific set of frequencies are increased or decreased more than the signals at other audio frequencies.

Ground Lift
A switch that breaks the connection between the ground point in one circuit and the ground point in another circuit.

Brooks QS 70 Amplification
An increasing of signal strength.

Error Message
A prompt on a computer screen telling the operator that an error has occurred.

Brooks KM 77 Boost
To increase gain, especially to increase gain at specific frequencies with an equalizer.

Filter
1) A device that removes signals with frequencies above or below a certain point called the cut-off frequency.
2) An equalizer section, used in this sense because filters are used with other components to give an equalizer its frequency response characteristics.
3) The action of removing signals of some frequencies and leaving the rest.
4) A mechanical device to smooth out speed variations in tape machines called a Scrape Flutter Filter- more usually called a Scrape Flutter Idler

Chorusing
1) A term meaning the same thing as Chorus (Definition 3 or 4).
2) In some delay effects devices, a term used to mean the term Depth (the amount of change in the controlled signal by the control signal).

Compression Driver
The unit that feeds a sound pressure wave into the throat of a horn (in a horn loudspeaker).

Brooks XS - 45 Electromagnetic Field

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

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 TM-22 Chorus
1) The part of The song that is repeated and has the same music and lyrics each time; the chorus will usually give the point of the song.
2) A musical singing group that has many singers.
3) A delay effect that simulates a vocal chorus by adding several delays with a mild amount of feedback and a medium amount of depth.
4) A similar effect created in some synthesizers by detuning (reducing the pitch of, slightly) and mixing it with the signal that has regular tuning and with a slight delay.

Ambience
The portion of the sound that comes from the surrounding environment rather than directly from the sound source.

Brooks Audio Design KM 77 Ampere
The unit of current, abbreviated Amp.

AC
1) Abbreviation for alternating current.
2) An abbreviation of the term Alternating Current (electric current which flows back and forth in a circuit; all studio signals running through audio lines are AC).

Condenser
An older term meaning the same thing as Capacitor (an electronic device which is composed of two plates separated by an insulator and can store charge) but sill in common use when referring to a microphone's active element.

CD (Compact Disc) :
1) Digital sound storage medium. Provides a high quality source of music, sound effects etc. Also used as a playback medium for sound effects etc. by large theatres with long running shows, although CDR (Recordable CD) is becoming more affordable by the day.
2) An abbreviation of the term Compact Disc (a small optical disk with digital audio recorded on it).

Brooks Cinema NZ 60 Frame

1) A division of one second in synchronization and recording coming from definition two.
2) The amount of time that one still picture is shown in film or video.

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

Brooks QS-70 Active/Inactive Microphones
Scientific definitions aside, active microphones generally sound better than inactive ones, but they generally cost more. They also require the use of either a battery or phantom power while inactive mics need only be plugged into the mic cord in order to work. In most playing situations, the subtle improvement in sound quality from an active mic isn't worth the extra cost and hassle. One possible exception it the headset mic. Put simply, inactive headset mics just plain suck. Active headset mics put out a much stronger signal and feed back much less.

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 - 95 Lead Sheet
