Brooks Cinema TZ 505 Integrated Circuit (IC)
A miniature circuit of many components in a small, sealed housing with prongs to connect it into equipment.

Condenser Mic (Capacitor Mic)
A microphone that uses the varying capacitance between two plates with a voltage applied across them to convert sound to electrical pulses. Condenser microphones need a power supply to provide the voltage across the plates, which may be provided by a battery within the case of the microphone, or it may be provided from an external phantom power supply. A condenser mic is more sensitive and has a faster reaction to percussive sounds than a Dynamic mic and produces a more even response. See Electret Mic.

Expansion
The opposite of compression; for example, an expander may allow the signal to increase 2 dB every time the signal input increased by 1 dB.

Cycle
1) An alternation of a waveform which begins at a point, passes through the zero line, and ends at a point with the same value and moving in the same direction as the starting point.
2) On a Solid State Logic Console, a command to have the console computer control the tape machine to play and replay a certain section of the tape.
