SW10 - Back of Subwoofer
(refer to diagram above)
(1) Auto/On/Off
- Activates power for subwoofer (ON),
or puts the subwoofer in automatic standby mode
(AUTO).
(2) Power Indicator
- The green light is lit when the sys-
tem is on. The light is off when the subwoofer is in stand-
by mode. The red light is lit when the subwoofer is in pro-
tection.
(3) Gain Control
- Adjusts the loudness of the subwoofer
independently of the main speakers.
(4) Low-Pass Filter
- Continuously variable low-pass
crossover control.
(5) Audio/Video Contour Switch
- Selects response
mode of subwoofer.
(6) Subwoofer Phase Selector
- 2-position selectable
phase control for subwoofer.
(7) Line In
- Low level RCA input jacks.
(8) Line Out
- Low level RCA output jacks to receiver/
main amplifier.
(9) Output to Satellites
- 5-way binding posts for speak-
er-level connection to main speakers.
(10) High Level Input
- 5-way binding posts for speaker-
level input from receiver/amplifier.
(11) Fuse Holder
Connecting The SW10
Caution: Before connecting the SW10 to your audio
system, it is important to unplug or turn off all AC power
connections to connected components such as
receivers, amplifiers, preamplifiers, and processors. Do
not plug in or connect the SW10 subwoofer to AC power
until all connections have been made.
How well a subwoofer performs with the rest of an
audio/video system depends mostly on how it interacts
with the main (largest) speakers.
Since a subwoofer reproduces
only
low frequencies, it is
important to ensure that it integrates seamlessly with
your main speakers. For this reason, we've provided
four different ways to connect your subwoofer, each of
which will best suit certain types of systems.
Considering Your Systems
To determine which type of connection is best for your
system, first look at what type of equipment you have: ie,
your receiver / amplifier ("amp") or preamplifier ("pre-
amp").
• For amps and preamps which offer the ability to loop
signals both in and out, all four connection methods will
work.
• For amps and preamps offering only line level outputs
(pre, line, or sub/LFE), use any except the first (Low-
Level Filtered) method.
• For amps offering only speaker-out connections, use
one of the High-Level (speaker-level) methods.
Next, review your main speakers' specifications and
consider the following:
• If you're using large, full-range main speakers you will
likely prefer an unfiltered connection method. This will
allow the subwoofer to augment the lowest frequencies
in music systems. For surround systems, NHT recom-
mends using the subwoofer/LFE output on your amp or
preamp, which will allow your main speakers to operate
full range.
• If you're using smaller main speakers having limited
bass response, NHT recommends using a filtered
connection. This will allow your main speakers to play
louder with less stress, while the SW10 provides the low
frequencies.
