The Four Connection Methods:
1)
Low-Level Filtered
What it does: feeds full-range signal to the SW10, whose
high-pass filter sends low frequencies to the subwoofer
and returns only higher frequencies back to your amp,
preamp or receiver, which will then send it on to your
main left and right speakers.
Benefit: your main speakers will receive only frequencies
they can easily reproduce, which effectively increases
their dynamic range and power output.
Use if:
Your amp or receiver offers line out or Pre Out and Main
In jacks -OR- you use a separate preamplifier and ampli-
fier.
To connect for a Line-Level Filtered signal (Fig. 1), keep
your main speakers connected as usual, but use RCA
line-level audio cables to connect as follows:
• For a component with Pre Out and Main ln jacks,
connect the Pre Out(s) to the SW10's LOW LEVEL
INPUT, and the SW10's LOW LEVEL OUTPUT back to
the component's Main ln(s).
• For a system with separate preamplifier and amplifier,
connect your preamp's Pre Out(s) to the SW10's LOW
LEVEL INPUT, and the SW10's LOW LEVEL OUTPUT
back into your amplifier's Line Inputs.

2)
Low-Level Full-Range
What it does: uses the subwoofer for low bass
augmentation, while still sending your main speakers
unfiltered, full range audio signals.
Use if:
You wish to run your main L & R speakers full-range
-AND-
You have a receiver with Subwoofer (LFE) Out jacks
-OR-
You have an amp or receiver with Pre-Out jacks but no
Main-In jacks.
To connect for a Line-Level Full-Range signal (Fig. 2),
keep your main speakers connected as usual, but use
RCA line-level cables to connect as follows:
• Preamps with Line Out jacks: connect one pair of Line
Out cables to your main amp to power your main L & R
speakers, and a second pair to the SW10 LOW LEVEL
INPUT. If your preamp has only one pair of Line Out
jacks, you can use a pair of "Y" connector cords,
available through your NHT dealer.
• Amps and receivers with Pre-Out or but no Main ln
jacks: connect the SW10 from the Pre-Out into the
SW10's LOW LEVEL INPUT. This will leave main speak-
er outputs unchanged.
• Components with Subwoofer Out / LFE Out jack: con-
nect an RCA audio cable from the Sub/LFE output into
either the left or right LOW LEVEL jack on the SW10 (it
doesn't matter which), or use a "Y" connector cord to
feed the signal into both jacks.
Note: We recommend that you avoid having multiple
filters act on the subwoofer signal. Check the owner's
manual for the component offering the Subwoofer / LFE
Out to see whether it sends a filtered signal (most Dolby
Digital receivers and amps have their own low frequency
