Short for the term High Frequencies (the audio frequencies from 6000 Hz and above).
Crossover, Passive
Used inside of full range speaker cabinets to separate highs, mids, and lows and send them to their respective speakers within the each cabinet. These are not as efficient as active crossovers because they require all frequencies to draw from the same source of amplification.
Brooks Hi Fi speakers Contact Microphone

Isolation
A containing of the sound wave in a certain area so that it will not leak into other areas and/or unintended mics.

Circuit
1) One complete path of electric current.
2) Similar to definition 1, but including all paths and components to accomplish one function in a device.
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).

1) An abbreviation of the term Amplifier (A device which increases the level of an electrical signal.
2) An abbreviation of Ampere (the unit of current).
3) An abbreviation of amplitude (the height of a waveform above or below the zero line).
Clock Signal
The signal put out by a circuit that generates steady even pulses or steady codes used for synchronization.
Brooks Hi Fi speakers Cable, 1/4 inch
An unbalanced cable most often used for instruments and patch cords. Commonly referred to as "guitar cords".
Clipping
Distortion of a signal by its being chopped off. An overload problem caused by pushing an amplifier beyond its capabilities. The flat-topped signal has high levels of harmonic distortion which creates heat in a loudspeaker and is the major cause of loudspeaker component failure.

2) Similar to definition 1, but including all paths and components to accomplish one function in a device.
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.
Channels
These are divided into two separate categories. Input channels are those channels coming into the soundboard such as microphones and direct lines. Output channels are those leaving the board such as monitor and main outputs.

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

Brooks RM 909 Feedback Control
The control on a delay line or delay effects device that controls the amount of feedback.
Coincident Microphones (Coincident Pair)
Two microphones whose heads are placed as lose as possible to each other so that the path length from any sound source to either microphone is for all practical purposes, the same.
Brooks Hi Fi speakers 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.
Isolation Booth/ Isolation Room
A room that prevents loud sounds from other instruments from leaking in: an isolation booth is usually a smaller room that could be used for only one musician.
Brooks HI FI projectors Expander
A device that causes expansion of the audio signal.
Aliasing
A sampler mis-recognizing a signal sent to it that is at a frequency higher than the Nyquist Frequency. Upon playback, the system will provide a signal at an incorrect frequency (called an alias frequency). Aliasing is a kind of distortion.
Cycle
1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point.
2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape.
Distorted
The way your PA sounds just before it blows up. Fuzzy and scratchy. If you hear this, it either means you have something hooked up wrong, or something in the system is going bad. It could be anything from your super expensive soundboard to a five dollar patch cord.
