Brooks Cinema xm 808 Linearity

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

Jam Sync
A generation of new SMPTE according to the input SMPTE signal

Brooks BA 71 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.

Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Brooks Speakers Impedance
1) A term for the electrical resistance found in a/c circuits. Affects the ability of a cable to transmit low level (e.g. sound) signals over a long distance. Measured in Ohms. Speakers are rated according to power handling capabilities (Watts, W) and impedance (Ohms).
2) The total opposition offered by an electric circuit to the flow of an alternating current of a single frequency. It is a combination of resistance and reactance and is measured in ohms. Remember that a speaker's impedance changes with frequency, it is not a constant value.
3) The opposition to alternating current.

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.

Direct box
Used in line to convert a high impedance signal into a low impedance signal.

Group Master
A slide control used to send out a control voltage to several VCA faders in individual channels, thus controlling the gain of several channels.
