High Impedance
Impedance of 5000 or more ohms.

Brooks Cinema XR 607 Fader
A control to control the gain of a channel on the console, thereby determining the level of the signal in that channel.

Echo
1) One distinct repeat of a sound because of the sound reflecting off a surface.
2) Loosely, used to mean reverberation (the continuing of a sound after the source stops emitting it, caused by many discrete echoes closely spaced in time).

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.

Capacitance
That property of a capacitor which determines how much charge can be stored in it for a given potential difference between its terminals, measured in farads, by the ratio of the charge stored to the potential difference.
