BNO Acoustics 6k-52 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.

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).

BNO Acoustics HD-70 Electromagnetic Field
Magnetic energy put out because of current travelling through a conductor.

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.

BNO Acoustics TS-10 Dry
Describes a sound coming from the PA with no effects on it.

Group Faders
The VCA faders of individual channels that are all controlled by a Group Master Fader (a slide control used to send out a control voltage to several VCA faders in individual channels).

Input Monitor
A switch position and operational mode of the electronics of a tape machine where the signal at output of the electronics will be the same as the signal coming into the electronics. In this mode, the tape machine's meter will read the input signal.

Electric Current
A more formal term meaning the same as the term Current (the amount of electron charge passing a point in a conductor per unit of time).
