WARNING! Exercise caution when setting INTELLi Q. Maximum boost can potentially cause woofer damage due to over-excursion. 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 Q Incorporated in the high-pass crossover, INTELLi Q maximizes the performance of a sub- woofer. The high-pass subsonic filter removes unwanted bass output from the woofer, increasing the output of a subwoofer by as much as 3 dB due to the increased mechanical power handling. Depending on the enclosure, using INTELLi Q can increase the low frequency response by an additional 10dB! The type of enclosure used and the woofer's excursion capability determine acceptable boost levels. Listed below are recommended boost levels for different enclosure designs. © 2005 Directed Electronics, all rights reserved Enclosure Type 0dB +3dB Boost Levels +6dB +10dB Infinite Baffle Tune above Fs of woofer High X-Max Drivers--Tune above Fs of woofer Not Not Recommended Recommended Sealed Tune above Fs of woofer Tune above Fs of woofer High X-Max Drivers--Tune above Fs of woofer Not Recommended Vented Tune to port frequency Tune to port frequency Tune to port frequency High X-Max Drivers--Tune to port frequency Sealed Band-pass Tune above Fs of woofer Tune above Fs of woofer High X-Max Drivers--Tune above Fs of woofer Not Recommended Vented Band-pass Tune to port frequency Tune to port frequency Tune to port frequency High X-Max Drivers--Tune to port frequency Aperiodic Set crossover to Fs of woofer Set crossover to Fs of woofer Set crossover to Fs of woofer Not Recommended Infinite Baffle Example High-Pass Set at 30Hz 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 left graph displays the frequency response of a 12-inch woofer in an infinite baffle application without the high-pass filter, with the filter and with the filter and the INTELLi Q set to +3dB. 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. NOTE: The left graph is the response; the right graph is the driver excursion. These designations apply to the following graphs as well. © 2005 Directed Electronics, all rights reserved Sealed Example High-Pass Set at 20Hz This sealed example is the same 12-inch woofer in the recommended sealed enclosure. Up to 6 dB of boost is capable if 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz. Sealed Example High-Pass Set at 30Hz In this example, the frequency has been increased to 30 Hz. Up to 6 dB of boost is capable at this frequency. With +6dB of boost, the woofer has more output down to 23 Hz. The overall usable output is increased. Vented Example High-Pass Set at 30Hz Vented enclosures benefit most from the INTELLi Q. Up to 10 dB of boost is capable at the box tuning frequency of 30 Hz. With +10dB of boost, the woofer has more output down to 22 Hz. The excursion below the tuning frequency has been greatly reduced. © 2005 Directed Electronics, all rights reserved Remote Gain Operation NOTE: Do not use the Remote Gain control when you have an expanded system installed (see Line Ouput Configurations). The Slave amplifier(s) gain will not be controlled. The remote gain port provides easy remote access to the internal gain structure of the HCCA power amplifier. The HP-RB1 plugs into the amplifier via the 1/8" mini jack plug. The HP-RB1 can be installed in the front of the vehicle to control the amplifier gain level. The HP-RB1 can be used as a bass level control when used on an amplifier dedicated to subwoofers. AMPLIFIER WIRING Power Connections for the HCCA-D1200, and HCCA-D2400 .
