The following pages show some typical
connections that you might make in your
installation. They show how the inputs
and outputs of the Sunfire Subwoofer are
connected to your preamplifier or
receiver.
If your preamplifier has a
subwoofer output (often
labeled LFE for Low
Frequency Effects), it can
be connected to the
subwoofer’s Left (Mono)
input as shown. This is the
simplest and recom-
mended connection. A
receiver with a sub/LFE
output can be connected in
the same way.
The subwoofer will play
the low frequency range
and the other speakers will
play the frequency range
delivered to them by your
amplifier.
If you have a home
theater preamplifier, it may
have an independent
subwoofer volume and
crossover control. Make
sure this is correctly
adjusted, and that the
Sunfire Subwoofer’s
crossover frequency is set
to 100 Hz. This is by no
means an iron-clad rule,
rather it is a good starting
point. (See the crossover
frequency control details
on page 6 and adjustments on page 15).
You can set the subwoofer’s Bass
Level control to 0dB, and then use the
preamplifier’s subwoofer level control for
normal and routine adjustments.
