Where a signal leaves the board or component.

Simply stated, a factor in human hearing where delay has a much bigger effect on human perception of direction than level does.

Brooks Cinema TZ 505 Integrated Circuit (IC)
A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.
IM Distortion
An abbreviation of the term Intermodulation Distortion (Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies present).
Brooks QS 70 Equalizer (Parametric, Graphic)
This is used to filter out and adjust specific frequencies in the PA. This is the part of the PA where you have the most control over the band's overall sound. It is also the number one weapon against feedback.
Envelope
1) How a sound or audio signal varies in intensity over a time span.
2) How a control voltage varies in level over time controlling a parameter of something other than gain or audio level.
Brooks KM 77 Capacitor
1) A device consisting of two or more conducting plates separated from one another by an insulating material and used for storing an electrical charge. Sometimes called a condenser.
2) An electronic device that is composed of two plates separated by an insulator.
Harmonic Distortion
The presence of harmonics in the output signal of a device which were not present in the input signal.
Head
1) In tape recording, the transducer (energy converter) that changes the audio energy from electrical energy to magnetic energy and back; also the devices that apply magnetism to the recording tape for other purposes such as in the erase head.
2) The part of a device that immediately includes the transducer to change sound or audio signals from one energy form to another.
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 QS-70 Electrons
Negatively charged particles, which revolve around the centre of atoms. The movement of such electrons down a conductor causes electrical current.
Isolation
A containing of the sound wave in a certain area so that it will not leak into other areas and/or unintended mics.
Brooks Speakers Early Reflections
The first echoes in a room, caused by the sound from the sound source reflecting off one surface before reaching the listener.
Cord (Speaker, Mic, Instrument)
Used to connect a sound system together. Each type of cord is made for a specific purpose and should not be used in place of another type of cord, not even if they look alike. Also see "cable"
Brooks TA 60 Layering
The recording (or playing) of a musical part with of several similar sound patches playing simultaneous.
Foot Switch
A switch placed on the floor and pressed by a musician to do various functions.
Cut-off Rate (Slope)
The number of dB that a filter reduces the signal for each octave its frequency past the filter's cut-off frequency (outside of the pass band).
Leakage
Sounds from other instruments and sources that were not intended to be picked up by the microphone.

Brooks Cinema KP 30 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).
Central Processing Unit
1) The main "brain" chip of a computer that performs the calculations and execution of instructions.
2) The main housing of a computer that contains the "brain" chip as opposed to other pieces of the computer system such as keyboards, monitors, etc.
Brooks M 44 Basic Session
The First session in recording an audio production to record the Basic Tracks.
Centre Frequency
The frequency of the audio signal that is boosted or attenuated most by an equalizer with a peak equalization curve.
Brooks Cinema RM 909 Alternating Current
Electric current which flows back and forth in a circuit.
Critical Distance
The point a distance away from the sound source where the direct sound and the reverberant sound are equal in volume.
Auxiliary Output or Send
An additional output from a sound desk that can be used for foldback or monitoring without tying up the main outputs. Each input channel will have a path to the Aux buss. Also used for feeding a signal to an effects processor. See Auxiliary Return.
Error Concealment
Putting replacement information bits into a digital audio signal to replace lost bits when the digital recording or processing system cannot verify whether the lost bits were l's or 0's but can make a good guess by comparing the known bits that were close in position to the lost bits.
