Twist the gain dial on your amplifier.
Turn it up (clockwise) until the sound (music, talking, test tone, etc.) is as loud as you might ever want to listen to it, so long as you do not hear any sound distortion or overload your speakers. If you do hear a distortion, turn the gain back down until the distortion is gone.
In this manner, what does the gain do on an amplifier?
An amplifier gain control (input sensitivity) is simply an level-matching device allowing you to match an amplifier's input circuit to a source unit's (or signal processor) output. Ideally gains are set so an amplifier's output "clips" at the same time the source unit "clips".
- Select [Setup] - [Audio Settings] from the home menu.
- Select [Subwoofer Low Pass Filter].
- Select the setting you want. On: Always activates the low-pass filter with a cutoff frequency of 120 Hz. Off: Does not activate the low-pass filter.
Subsequently, one may also ask, should power amps be turned all the way up?
The level controls of the power amps should be set so you maintain consistent gain staging throughout your system, while allowing ample headroom. If you need to turn them up all the way to achieve that (as is often the case) then you certainly should.
Make sure those are all turned off, too.
- Start by turning the gain down, and turn off your filters and bass boost.
- Turn the gain up until it distorts, then back it off until the sound is clean again.
- Adjust the low-pass filter downward to eliminate high- and mid-frequency notes.
- Now play with the bass boost.
