A grouping of eight information bits.

High Impedance Mic
A microphone designed to be fed into an amplifier with input impedance greater than 20 k ohms.

Brooks Hi Fi reviews Golden Section
A ratio of height to width to length of a room to achieve "good acoustics" and first recommended by the ancient Greeks. The ratio is approximately the width 1.6 times the height and the length 2.6 times the height

Controller
1) In MIDI, a device that generates a MIDI signal to control synthesizers, sound modules or sample playback units.
2) A remote control unit for a multitrack tape machine which controls transport functions as well as monitor selection switching functions and record ready/safe status of each track.

Brooks Hi Fi speakers Line Level
1) An amplified signal level put out by an amplifier and used as the normal level that runs through the interconnecting cables in a control room.
2) A low level signal such as the signal in a guitar cord. Most parts of a PA require a line level signal. Remember, however, that speaker outputs are not line level. Plugging speaker outs into line ins will result in damage to the equipment

Amplifier
A device which increases the amplitude (level) of an electrical signal (making it louder).

Keying Input (Key Input)
An input on a dynamics processing device to control the device by an external audio signal.

Group Master
A slide control used to send out a control voltage to several VCA faders in individual channels, thus controlling the gain of several channels.
