Volume: Adjusts the sound level of the subwoofer. A typical setting is around 10 o’clock.
Crossover (Hz): Adjusts the frequency of the low-pass filter for the subwoofer.
Polarity (0° or 180°): Selects regular (0°) or inverted (180°) polarity for the subwoofer. Set this switch to provide the
fullest, most dynamic bass. The effect of phase will be most audible on low-frequency percussion instruments or music
with a continuously repeating bass line.
Power off/on: Switches the amplifier on and off. Once switched to the “on” position, the PV350’s auto-on circuitry
turns the subwoofer on when a signal is presented, and turns it off after no signal is detected for several minutes.
