BASS
Music / Electroacoustics The frequencies or PITCHes in a low RANGE, usually undefined as to the specific limits implied. Opposite of TREBLE. In music it refers to the lowest singing range, or any instrument playing a low-pitched part, as well as the lowest musical part itself.
Many amplifiers intended for home use have one control marked 'bass' which alters the GAIN given to lower frequencies. However, such a simple control does little to improve sound FIDELITY in any meaningful way, and is more generally used to eliminate HUM in poorly grounded equipment, or to exaggerate low frequencies with certain types of music.
