Crossover Functions: High Pass Filter allows adjustment: It determines the beginning of the channel operating frequency. This filter allows the amplifier to work with many different applications such as Woofer / Midbass / Midrange / Compression Driver components allows the elimination of low-frequency sounds, delivering the right frequency range to avoid damage to the components. Low Pass Filter allows adjustment: It determines the end of the channel operating frequency. This filter allows you to fine-tune the amplifier frequency response to match the components’ frequency response. This ensures that only the lowest frequencies are reproduced by the amplifier. Bass Boost allows adjustment: Bass Equalizer: provides a “gain attenuation” 0 to + 12dB at the center frequency of 45Hz. On/Off Buttons: This button allows to quick turn On and Off each individual channel. Level knobs: This control adjusts the output signal on channel; which allows an optimal adjustment to the output signal levels to the amplifiers. HIGH OUT channel: This Stereo output channel take the signal from the FRONT IN stereo inputs HIGH PASS filter from 400Hz to 10,000Hz Recommended application: Tweeters, Titanium Compression Drivers, and Super Tweeters. MID HIGH OUT channel: This Stereo output channel take the signal from the FRONT IN stereo inputsHIGH PASS filter from 150Hz to 5,000Hz LOW PASS filter from 700Hz to 12,000Hz Recommended application: Compression Drivers and Mid Range Speakers. MID LOW OUT channel: This mono output channel take signal from the FRONT IN or MID LOW IN input. HIGH PASS filter from 25Hz to 4,000Hz LOW PASS filter from 300Hz to 9,000Hz Recommended application: Phenolic Compression Drivers, Woofer, Mid Bass, and Mid Range Speakers. SUB OUT channel: This mono output channel take signal from the FRONT IN or SUB IN input.LOW PASS filter from 55Hz to 300HzBASS BOOST gain + 12dB at the center frequency of 45Hz Recommended application: Woofer and Subwoofers.
