Brooks Gt 44 Compander
1) A two section device that is used in noise reduction systems. The first section compresses the audio signal, before it is recorded, and the second section, expands the signal after recording.
2) In Yamaha brand digital consoles, a signal processing function that applies both compression and expansion to the same signal.

Linearity
The extent to which any signal handling process is accomplished without amplitude distortion.

Balls
1) The depth and thickness of a sound, usually on the bottom end of the EQ (as in "needs more balls"). 2) The strength of the voice on the mic (as in "check it like you have some balls").

Echo Return
An input of the console, which brings back the echo (reverberation) signal from the echo chamber or other echo effects device.
