Low-Pass Crossover
Both sets of inputs sum the left and right channels together and the resulting signal is passed through an
adjustable low-pass crossover before being amplified. The crossover control allows you to adjust the upper
limit of the subwoofer’s frequency response from 40 to 120 Hz. The subwoofer’s response will begin rolling off
above the frequency you set this control to. you should set the crossover frequency to obtain a smooth and
seamless transition from the subwoofer to the main speakers in your system. If your main speakers are smaller
units with limited low frequency output, you may wish to choose a higher frequency (such as 100-120 Hz) than
you would with larger speakers which have greater low frequency output. with larger speakers, you might start
with this control set lower, such as 70 Hz.
Subwoofer Direct
Subwoofer Direct is a setting on the low-pass crossover knob and will allow frequencies up to 120 Hz into the
subwoofer. See below for a more detailed explanation of this feature.
