A low-noise amplifier designed to take a low-level signal and bring it up to normal line level.
Often shortened to PFL. Control on a sound mixing desk which allows the user to check the presence of a signal, and its quality before bringing up the fader. Also vital for fault-finding, where the route of a signal can be PFL'ed around the desk until the point where the fault occurs. Also known as Check and Cue.
1) Another term for ponging (playing several recorded tacks with sync playback through a console to mix them together and record them on an open track).

A factor in human hearing where delay has a much bigger effect on the human perception of the location of the sound source than level does.
An output from a sound desk is said to be prefade if it is independent of the channel fader. If it is postfade, the level of the output is relative to the channel fader.
