Orion Car Audio HCCA-D600 Low-Pass Crossover, Fine Tuning the Crossovers, Adjusting INTELLi-Bass

Page 9

WARNING! DO NOT set crossover frequencies lower than the speakers recommended operating range. This can cause driver failure that is not covered by the man- ufacturer's warranty.

Low-Pass Crossover

The low-pass crossover adjusts the upper crossover of the filter and is continuously variable from 30Hz to 250Hz.

Fine Tuning the Crossovers

The low-pass and high-pass crossover sections are each marked at four frequency points for ease of system adjustment. The low-pass crossover section is marked at 30Hz, 50Hz, 150Hz, and 250Hz. The high-pass crossover section is marked at 20Hz, 33Hz, 90Hz and 150Hz. Specific crossover points can be chosen based on the recommended operational bandwidth of your speakers.

Adjusting INTELLi-Bass

INTELLi-Bass on the rear channels maximizes the performance of a subwoofer and allows for continuous adjustment of low frequency boost on the rear channels. INTELLi-Bass can be adjusted from 0dB to 18dB of boost centered at 45Hz. Initially the Q is very low (wide). As INTELLi-Bass 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 capabil- ity, personal preference, and attitude determine acceptable boost levels.

WARNING! Exercise caution when setting INTELLi-Bass. Maximum boost can potentially cause woofer damage due to overexcursion.
