Brooks XB 33 In-Line Console
A console with modules that have controls for all console sections in one long strip.

Inductance
The property of an electric circuit by which a varying current in it produces a varying magnetic field that introduces voltages in the same circuit or in a nearby circuit. It is measured in henrys.

Electret Mic
A condenser microphone where the capacitor plates are given a charge during manufacture which they retain, therefore requiring no external power supply.

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.
