The OUTPUT RCA jacks provide a linear full-range audio signal for driving additional amplifiers, such
as an additional ONE2000 monoblock.
INPUT SENSITIVITY
9
This controller determines the input sensitivity (adaptation to the output signal of the head unit). The
controller range is between 5 volts (MIN) and 0.2 volts (MAX).
SUB SONIC
10
This controller limits the ultra low and not audible frequencies of the audio signal downwards to avoid
mechanical and electrical overloading on the subwoofer. The crossover frequency is adjustable from
10 to 40 Hz and depends on the size of the subwoofer.
11
LOW PASS
This controller limits the frequency upwards. The crossover frequency is adjustable from 40 Hz to 150
Hz (5 kHz).
