High-Pass Crossover

When the switch is to the center (FULL position), the high-pass cross- over is bypassed.. When the switch is to the right, the high-pass cross- over is active.. The high-pass crossover is continuously variable from 50Hz to 2000Hz..

Adjusting Bass Boost

Bass Boost maximizes the performance of a subwoofer and allows for continuous adjustment of low frequency boost on the rear channels.. Bass Boost can be adjusted from 0dB to 18dB of boost centered at 45Hz.. Initially the Q is very low (wide).. As Boost is added, the Q rises (narrows).. This allows the amplifier to overcome acoustic deficiencies in your vehicle.. The type of enclosure used, the sub-woofer’s excursion capability, personal preference, and attitude determine acceptable boost levels..

WARNING! Exercise caution when setting Bass Boost.. Maximum boost can potentially cause woofer damage due to over-excursion..

NOTE: While the amplifier allows up to 18dB of boost, it is possible to clip the amplifier with comparatively low output levels in other frequency ranges..

Infinite Baffle Subsonic is set at 20Hz

By removing low frequency signal that the woofer cannot produce, the woofer can play its capable range louder.. The first example is an infinite baffle situation.. The first graph displays the frequency response of a 12-inch woofer in an infinite baffle application without the high-pass filter.. As you can see, with +3dB of boost and the high

pass filter set to 30Hz, the woofer has more output down to 25Hz and less overall excursion when compared to the non-high-pass response.. Maximum physical excursion capability of the woofer is 15mm..
