: Component that boosts or cuts sound signal frequencies to improve the

quality of the sound.

Gain control

: gain is the amount of amplification (voltage, current or power) of an

audio signal expressed in dB.

Hz

: Abbreviation for Hertz, a unit of frequency equal to one cycle per second.

IVS

: Input Voltage Selector

Octave

: the musical principle of dividing sound frequencies into the eight notes of the

musical scale.
