This is the name given to the amplification of a signal level. It can be expressed as a ratio of the output signal amplitude to the input signal amplitude. For example, Voltage gain:
Gain = Vout / Vin
Gain is normally expressed in dB.
For voltage gain use:
Gain (dB) = 20 log10 Vout/Vin
For current gain use:
Gain (dB) = 20 log10 Iout/Iin
For power gain use:
Gain (dB) = 10 log10 Vout/Vin
This is a device which adjusts the gain of an amplifier. This is normally done by altering the amount of negative feedback in the amplifying system. A Gain Control is not the same as an ‘attenuator’ or a ‘volume’ control.
This technique uses small segments of either sampled or synthesised sound to generate a new sound or sound texture.
This is a condition that occurs when two or more paths to ground exist and an unequal voltage is induced in each of the paths causing buzz, hum or other noise.
This is a Mixing Desk channel to which a group of audio signals can be routed to allow the treatment and control of the resulting combined signal.
Long, normally wood, section of the guitar that the strings are stretched over.
The guitar nut is a strip, between the fret board and headstock, on which the guitar strings sit. The nut normally has small notches which are used as guitar string guides.
