System Configurations
If your AV Receiver / Preamplifier has a subwoofer output (often labeled LFE for Low
Frequency Effects), it can be connected to the subwoofer’s left or right input as shown.
This is the simplest and recommended connection. An AV 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.
Your AV Receiver / Preamplifier may have an independent subwoofer volume 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 ironclad rule, rather it is a good starting point.
(Refer to the crossover frequency control details within this document, as well as your
AV Receiver / Preamplifier User’s Manual.)
You can set the subwoofer’s level control
to 0 dB, and then use the preamplifier’s
subwoofer level control for normal and
routine adjustments.
