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 boost level is identified by the corner markings. Acceptable boost levels are determined by the type of enclosure used and the woofer’s excursion capability. Listed below are recommended boost levels for different enclosure designs. “Q” BOOST FILTER RESPONSE On the left is a frequency response of the high-pass filter set to 30 Hz. On the right frequency response of the high-pass filter set to 20Hz. INTELLi Q levels of 0dB, 3dB, 6dB and 10dB are displayed respectively. page 39 INFINITE BAFFLE EXAMPLE HIGH-PASS SET @ 30Hz By removing low frequency signal which 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. SEALED EXAMPLE HIGH-PASS SET @ 20Hz This sealed example is the same 12 inch woofer in the recommended sealed enclosure. Up to 6 dB of boost is capable at 20 Hz was used. With +6dB of boost, the woofer has more output down to 15 Hz. page 40 SEALED EXAMPLE HIGH-PASS SET @ 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. Overall usable output is increased. VENTED EXAMPLE HIGH-PASS SET @ 30Hz Vented enclosure 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. page 41 AUXILIARY OUTPUT SECTION The auxiliary outputs offer ORION amplifiers easy unlimited system expansion . Routing signal from a source unit, pre-amplifier or equalizer is a matter of routing RCAs into the RCA Inputs and out the AUX outputs to the next XTREME or HCCA amplifier in the signal chain. When the switch is in the “COPY” position, the AUX RCA is an identical copy of the RCA inputs. The signal passes through a buffer stage so that an infinite number of HCCA amplifiers can be daisy chained without signal loss or overloading of the source unit. This maximizes the amplifier output and minimizes the potential for system noise. When the switch is in the “GAIN” position, the AUX RCAs are buffered through the gain stage of the amplifier. When the first amplifier in the signal chain is set this way, a remote gain controller can be installed in the amplifier and act as a “PREAMP” controlling the overall level of the system. Following amplifiers can be configured in either the “COPY” or “MASTER” configuration for an infinite number of XTREME or HCCA amplifiers in the signal chain without signal loss or overloading of the source unit. This maximizes the amplifier output and minimizes the potential for system noise. When the switch is in the “MASTER” position, the AUX RCA are buffered through the gain stage of the amplifier and filtered through the crossover section of the amplifier. When set this way, one amplifier’s gain and crossover setting can be sent to other amplifier down the signal chain. This can be useful for configuring multiple subwoofer amplifiers easily in a large SPL system. A Remote gain controller will also control the level of all the amplifiers following the amplifier configured in this master setting. An infinite number of XTREME or HCCA amplifiers in the signal chain without signal loss or overloading of the source unit. This maximizes the amplifier output and minimizes the potential for system noise. page 42 Remote Gain Secti...
