Describes a sound which covers all audible frequency ranges. As in "full range speaker cabinets."

Hi-Z
An abbreviation of the term High Impedance (Impedance of 5000 or more ohms).

A drawing of several curves showing how loud the tones of different frequencies would have to be played for a person to say they were of equal loudness.

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 ZL 44 Line Out (Line Output)
Any output that sends out a line level signal, such as the output of a console that feeds a recorder.

Close Micing
A technique of placing a microphone close to the sound source (within one foot) in order to pick up mainly the direct sound and to avoid picking up leakage or ambience.

Level
Sets output volume of individual PA input channels. Usually positioned as sliders at the bottom of the soundboard.

Boundary Mic
A microphone mounted on a flat plate that acts as a reflective surface directing sound into the mic capsule. Used for general pick-up over a large area. See PCC, PZM.

Brooks Speakers Harmonic Distortion

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

Gain Control
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 SS 81 Fret Buzz
A buzzing sound made when a note is not properly fretted. Common with cheap guitars or beginning guitar players.

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

Brooks Cinema Projectors BPM
An abbreviation of Beat Per Minute (the number of steady even pulses in music occurring in one minute and therefore defining the tempo).

Clock Signal
The signal put out by a circuit that generates steady even pulses or steady codes used for synchronization.

Cable, XLR
A balanced cable used for low impedance microphones and sometimes for connections between some parts of the PA. Commonly referred to as a "mic cord".

Barrier Micing
A method of placing the head of a microphone as close as possible to a reflective surface, preventing phase cancellation.

Brooks Cinema Series Capacitance

That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.

Hall
A large building designed for concerts; also called a concert hall.

Brooks GT 44 Automation
In consoles, a feature that lets the engineer program control changes (such as fader level) so that upon playback of the multitrack recording these changes happen automatically.

Cable, TRS
A less common balanced cable that has 3 different contacts on its 1/4 inch connectors. Most headphone jacks are a good example of a TRS (Tip-Ring-Sleeve) connector. These are sometimes used instead of the more common XLR connection.

Brooks XT 20 FOH (Front of House)
Refers to the speakers that face toward the audience. Also called the "main" speakers.

Layering
The recording (or playing) of a musical part with of several similar sound patches playing simultaneous.

Buss (Bus)
A wire carrying signals to some place, usually fed from several sources.

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

Brooks SS 81 Icon

A visual picture or symbol on a computer screen that represents a file, program or disc that can be used.

Buss (Bus)
A wire carrying signals to some place, usually fed from several sources.

Brooks Cinema Projectors Front Loaded
A speaker cabinet where the speaker faces out toward the front.

Balanced input/output
A "balanced" connection is one that has three wires to move the signal. One is a ground, and the other two (called conductors) carry signals of equal value. This is why they are called balanced. Low Z cables and connections are the most common example.

Brooks TA 60 Amplification
An increasing of signal strength.

Lift
1) To boost gain of audio at a particular band of frequencies with an equalizer.
2) An elevation device in the star trek series of TV programs.

Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

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).

Brooks KS-55 Flange

An effect caused by an approximately even mix of a modulated (varying) short delay with the direct signal.

Kick (Kick Drum)
Another term for Bass Drum.

Brooks Cinema XR 607 Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.

Fat
Having more than a normal amount of signal strength at low frequencies or having more sound than normal (by use of compression or delay).

Brooks QS 70 First Generation
A descriptive term meaning original (as opposed to a copy).

Binary
A numbering system based on two. In binary there are two symbols used ("l" and "0").

Analog To Digital Converter
The device which does the conversion of a quantity that has continuous changes (usually of voltage) into numbers that approximate those changes.

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.

The bits in the digital signal that make up actual values or commands being communicated as opposed to bits that are used for checking & correcting data or other purposes.

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

Brooks GT 44 Balanced
1) Having a pleasing amount of low frequencies compared to mid-range frequencies and high frequencies. 2) Having a pleasing mixture of the various instrument levels in an audio recording. 3) Having a fairly equal level in each of the stereo channels. 4) A method of interconnecting electronic gear using three-conductor cables.

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