AC VOLTAGE OPTION
The AC voltage option has been factory configured 100~120 V~.). Should the AC voltage need to
be changed to 220~240V~ loosen the screw on the protective cover, slide the cover away and the
slide switch can be adjusted. Make sure to replace the protective cover when done. Only make
this adjustment if the subwoofer will be connected to a voltage supply of between 220-240 VAC
@50Hz.
INPUT/OUTPUT CONNECTION OPTIONS
For most system configurations, connect the A/V surround receiver or processor’s Sub output to the
L/LFE input (3).
For a stereo music system where the stereo source features pre-amp level outputs, connect both
L/LFE and R inputs (3).
The pass-through stereo outputs (4) can be connected to a stereo power amplifier if needed. The
pass-through L/LFE output can be connected to another subwoofer if desired.
Niles offers a range of Balun adapters that allow audio signal transfer over standard Cat-5 network
cabling. Compared to coaxial audio interconnect cable, which can be costly over long runs and
more difficult to route through walls, Cat-5 cabling is usually less expensive on a per-foot basis,
and is easier to route through walls. Connect a suitable Niles Balun receiver/adapter to (10) to use
this option.
Niles also offers a wireless audio transmitter/receiver system, which eliminates the need for audio
signal cable connection to the subwoofer. Connect the wireless receiver to the wireless port (11) to
use this option. Refer to the wireless system’s instruction manual for further instructions.
CONTROLS
Turn-on Mode (6)
The Turn-on Mode provides the option to have the subwoofer in “always on” mode or to have the
subwoofer ordinarily in standby mode unless an audio input signal is present. The Signal Sense
mode automatically detects the presence of an audio input signal and brings the subwoofer out of
standby mode. This is the most energy efficient mode. With either mode, the main Power switch (2)
must be set to On. The default position from the factory is “Signal Sense”.
