BROOKS AUDIO reviews Gain Structure

The way in which the gain varies in the stages or sections of an audio system.

Chamber
1) An Echo Chamber (a room designed with very hard, non-parallel surfaces equipped with a speaker and microphone so that when dry signals from the console are fed to the speaker, the microphone will have a reverberation of these signals that can be mixed in with the dry signals at the console).
2) A program in a delay/reverb effects device that simulates the sound of an Echo Chamber.

Brooks Cinema ZL 44 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.

Diaphragm
A thin flexible membrane or cone that vibrates in response to electrical signals to produce sound waves. Distortion is usually referred to in terms of total harmonic distortion (THD) which is the percentage of unwanted harmonics of the drive signal present with the wanted signal. Generally used to mean any unwanted change introduced by the device under question.

Brooks GT 845 Compression Ratio
How many dB the input signal has to rise above the threshold for every one dB more output of a compressor or limiter.

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.

Amplifier
Sound equipment that converts the low voltage, low current signal from a tape deck, mixer etc. into a higher current signal suitable for driving speakers. See Power Amplifier, Crossover.

Generating Element
The portion of the microphone that actually converts the movement of the diaphragm into electrical current or voltage changes.
