#	Component	Description
4	Line level input	These RCA jacks accept a line-level, full-range signal
		from the pre-amplifier or LFE output of a receiver or
		preamplifier.
		This full-range signal is processed and amplified to
		power the subwoofer.
5	Polarity switch	This two-position switch allows the best match of
		acoustic output between the subwoofer and the
		satellite speakers in the crossover frequency region
		between them.
		• The 0° position maintains phase from input to
		output.
		• The 180° position changes the polarity by 180°.
		Try both settings and pick the one that sounds best.
6	Status LED	This shows the status of the subwoofer.
		• Red indicates that the amplifier is plugged in and
		the power switch is either off or in standby mode
		with no input signal present.
		• Green indicates that the amplifier is operating
		with a signal present at the input from the
		pre-amplifier, receiver, or power amplifier.
7	Subwoofer	This rotary control sets the upper frequency at which
	crossover	the output of the subwoofer begins to roll off.
	(frequency)	Continuously variable from 60 Hz to 160 Hz, it
		matches the upper frequency characteristics of the
		subwoofer to the low-frequency response of the
		satellite speakers.
		Recommended setting: 150 Hz.
8	Volume control	This rotary control adjusts the level of the subwoofer
	(gain)	and is used to balance its volume with that of the
		satellite speakers.
9	Main power switch	This switch controls the overall power status of the
		subwoofer. It must be in the ON position for the
		subwoofer to operate.
10	Fuse	For continued protection, replace the fuse with the
		same type and size listed.
