{16 } feet SDA data line to be implemented . N02 subwoofer signal is processed left channel signal and right channel signal from its respective pin { 22 } {12 } to the N03 and the transmission pin 30} { 26} and { foot pin while it is processed by the output it 's {12} feet by capacitance Cl8 N03 and R26 added 1 foot . In addition, a foot for an external 1000pF capacitor for high frequency components have - given a bypass , N03 2,3,4 -pin external 0.22μF and 0.1μF capacitors are integral components of the internal low -pass filter circuit N03 's . 1 foot bass signal input through its internal low-pass filter to filter out high-frequency signals above 400Hz , left and right channel signals are amplified by the N03 treated separately from the { 21 } { 22 } pin output , add the plug- XS201A
