A style of music with roots in Spanish and Arabic culture.
Ground Adapter Plug
Adapts a three pronged electrical plug to a two pronged wall outlet. This bypasses the ground and may create a hum in the system. A lack of a good ground can cause mild electrical shock when touching a microphone.
Lead
The musical instrument that plays the melody of the tune, including the vocal.
Fly In
1) To add sounds into a mix or recording that have no synchronization.
2) An application of this where a performance from one part of a tune is recorded and then recorded back into the recording at a different time in the recording.
Brooks Cinema KP 30 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.
Beats Per Minute BPM
The number of steady even pulses in music occurring in one minute and there fore defining the tempo of the song.
Brooks Cinema Projectors House Sync
A synchronization signal such as SMPTE time code that is used by all recorders in the control room.

Brooks QS 70 Amplitude
The height of a waveform above or below the zero line.
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 KS-55 Frequency Response
How sensitive an electronic device (mic, amplifier, speaker, etc.) is to various frequencies; often communicated with a graph.
Fly In
1) To add sounds into a mix or recording that have no synchronization.
2) An application of this where a performance from one part of a tune is recorded and then recorded back into the recording at a different time in the recording.
Brooks Cinema XR 607 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.
Hard Disk Recording
The recording of digital audio onto a hard disc.
Hypercardioid Pattern
A microphone pick up sensitivity pattern where the least sensitive pick up point is more than 90 degrees but less than 150 degrees off axis (usually 120 degrees).
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".

Brooks Cinema NZ 60
Brooks Cinema NZ 60 Chase
The automatic adjusting of the speed of a recorder (or sequencer) to be time with another recorder.
Headroom
1) The level difference (in dB) between normal operating level and clipping level in an amplifier or audio device.
2) A similar level difference between normal tape operating level and the level where the distortion would be 3%.
3) The difference, in decibels, between the peak and RMS levels in program material.
Brooks Cinema ZL 44 Balance
1) The relative level of two or more instruments in a mix, or the relative level of audio signals in the channels of a stereo recording. 2) To make the relative levels of audio signals in the channels of a stereo recording even.
Line In (Input, return)
Where a signal enters the board or component.
Brooks XB 22 Insert
1) A punch in of the all of the tracks being recorded in a recording session.
2) On Solid State Logic consoles, placing an outboard piece of gear in the channel by patching and activating a switch.
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.
Input Overload
Sending too high of a signal level into a device so that the first amplifier of the device overloads.
Earth
The British version of the term Ground (In electronics, a place that has zero volts).
