Gain Control (on a subwoofer)

Gain control on a subwoofer lets a user adjust the bass levels, or amplitude, to perfectly blend the output with other speakers in a home theater or hifi system to achieve optimum sound quality. Gain control differs from volume control in that it adjusts output relative to the input levels, whereas volume controls adjust the actual output level irrespective of input.

All SVS subwoofers offer variable gain control to let a user achieve their ideal bass response. One thing to remember is there is no “right” setting for gain controls, it’s an adjustable setting used to ensure proper bass levels during the calibration process.
