Sunfire True Subwoofer Signature and Standard Version Connections to a preampliÞer using Y cables

Connections to a preampliÞer using Y cables

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

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

Although bass is commonly dis-
tributed evenly between left and
right channels (L+R bass), movie
soundtracks often contain dif-
ferential (L-R) bass. The opening
scene in “Top Gun”, for example,
has loads of L-R bass infor-
mation. If this is not
preserved, the bass	PREAMPLIFIER

sounds anemic. The	SUB/LFE OUT			MAIN

utilizes differential
gain on the left and
right inputs to retain
both the L+R and
L-R information.
Therefore, systems		L	R

output should use
both the left and the
right inputs as shown, for the greatest
bass impact.

An alternative connection method without using Y cables is shown on the next page.

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.
