Connections to a preamplifier using Y cables

If your preamplifier does not have a sub/LFE output, you can use “Y” cables to send its main outputs to both the subwoofer and your amplifier.

The subwoofer will play the low frequency range and your front speakers will play the full range.

Although bass is com-
monly distributed evenly
between left and right
channels (L+R bass),
movie soundtracks often
contain differential (L-R)	PREAMPLIFIER
bass. The opening scene			L	R
in “Top Gun”, for example,	SUB/LFE OUT			MAIN
				OUTPUTS
has loads of L-R bass
information. If this is not
preserved, the bass in
these scenes sounds ane-
mic. The Sunfire Subwoofer
utilizes differential gain on		L	R
the left and right inputs to
	AMPLIFIER	INPUTS
retain both the L+R and
L-R information. Therefore,
systems which do not
have a dedicated sub/LFE
output should use both
the left and the right inputs
as shown, for the greatest
bass impact.			TO FRONT

If your preamp/receiver has a dedi- cated sub/LFE output, then only the Left (Mono) input is used, as shown on the previous page.
