Product Description: Crossover Functions

High Pass Filter Adjustment: This filter determines the beginning of the channel operating frequency, allowing the amplifier to work with various components such as Woofer/Midbass/Midrange/Compression Driver, and eliminating low-frequency sounds to deliver the right frequency range and avoid damage to the components.

Low Pass Filter Adjustment: This filter determines the end of the channel operating frequency, enabling the user to fine-tune the amplifier frequency response to match the components' frequency response, ensuring that only the lowest frequencies are reproduced by the amplifier.

Bass Boost Adjustment: The Bass Equalizer provides a "gain attenuation" of 0 to +12dB at the center frequency of 45Hz.

On/Off Buttons: This feature allows for quick and easy turning on and off of each individual channel.

Level Knobs: This control adjusts the output signal on each channel, allowing for optimal adjustment of the output signal levels to the amplifiers.

Channel Outputs: - HIGH OUT channel: This Stereo output channel takes the signal from the FRONT IN stereo inputs, with a 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 takes the signal from the FRONT IN stereo inputs, with a HIGH PASS filter from 150Hz to 5,000Hz and a LOW PASS filter from 700Hz to 12,000Hz. Recommended application: Compression Drivers and Mid Range Speakers. - MID LOW OUT channel: This mono output channel takes signal from the FRONT IN or MID LOW IN input, with a HIGH PASS filter from 25Hz to 4,000Hz and a 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 takes signal from the FRONT IN or SUB IN input, with a LOW PASS filter from 55Hz to 300Hz and a BASS BOOST gain of +12dB at the center frequency of 45Hz. Recommended application: Woofer and Subwoofers.
