9. r Subsonic This setting acts as a low frequency cut off for your system bass reproduction The point that you set it at cuts off any frequencies from reproduction beyond this point The 12 o clock position is a great starting point EXAMPLE If you adjust the Subsonic to 25Hz the amplifier will not play frequencies below 25Hz but will play frequencies from 25Hz to the chosen Low Pass frequency Bass EQ This setting is a fixed bass boost at 45Hz that is variable from 0 10dB This feature provides impact to your bass but if not adjusted correctly it can be over used and cause damage to your subwoofers and amplifiers It is best to slowly turn this setting clockwise until the desired punch is felt it is not recommended to exceed the 12 o clock position unless listening at a low volume or a low recording quality as this can result in high distortion and possibly clipping Low Pass The Low pass control acts as a ceiling and doesn t allow frequencies to the right of the desired setting to be reproduced The 12 o clock position is a great starting point EXAMPLE If you adjust the Low Pass to 80Hz the amplifier will not play frequencies above 80Hz but will play frequencies from 80Hz to the chosen Subsonic frequency Phase The variable Phase adjustment allows you to change the relative time that the waveform meets your ear With standard subwoofer installations where the subwoofer is behind you the Phase should generally be at 0 When subwoofe
