3. Input Mode - when the switch is out, the amplifier will accept

speaker level and high output RCA connections.. When this switch

is in, it provides extra sensitivity for lower input voltage RCA

6. X-Over Frequency Control (Flat / All Pass output)- adjusts the

frequency (50Hz–2000Hz) of the crossover for the HPF (High-Pass

Frequency Control) and the LPF (Low-Pass Frequency Control)

engaged when the Sub Sonic switch is On.. This improves efficien-

cy of the amplifier’s power supply, improves sound reproductive

performance, and reduces chances of damaging the subwoofers..
