Brooks Cinema ZL 44 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.

Crossover (Crossover Network)
A set of filters that "split" the audio signal into two or more bands (two or more signals, each of which have only some of the frequencies present).

Brooks Gt 44 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.

Crossover
1) A route leading from one side of the stage to the other, out of the audiences view.
2) An electronic filter in a sound system that routes sound of the correct frequency to the correct part of the speaker system. Different speakers handle high frequencies (tweeters) and low frequencies (woofers). Sometimes known as a crossover network. An active crossover splits the signal from the mixing desk into high, mid and low frequencies which are then sent to three separate amplifiers.
3) An electrical circuit that divides a full bandwidth signal into the desired frequency bands for the loudspeaker components.

BROOKS AUDIO reviews Intermodulation Distortion
Distortion caused by one signal beating with another signal and producing frequencies that are both the sum and the difference of the original frequencies.

Action
In guitar playing, action refers to how far the strings sit off of the guitar neck. When strings are close to the neck, it is referred to as "Low Action". When the string sit far above the neck, it is called "High Action". Guitars with low action are easier to play, but make sure they are not too close, or it could causing buzzing.

Ground Loop
A double grounding of a line or electronic device at two different "ground" points of differing voltage.

Interface
Any device that allows one unit to work, drive or communicate with another unit when they cannot do so by just feeding each other often because the units are manufactured by different companies.
