– for example, near a bathtub,

11. Servicing – Do not attempt to service the

subwoofer beyond those means described in this
operating manual. All other servicing should be

exposure.

Pour préevenir les chocs électriques ne pas
utiliser cette fiche polariseé avec un prolongateur,
un prise de courant ou une autre sortie de
courant, sauf si les lames peuvent être insérées à
fond sans laisser aucune pariie à découvert.

13. Grounding or Polarization –

grounding or polarization of the subwoofer.

14. Internal/External Voltage Selectors – Internal
or external line voltage selector switches, if any,
should only be reset and re-equipped with a prop­er plug for alternate voltage by a qualified service
technician.

15. Cleaning – Clean with a dry cloth only.

16. Where the mains plug or an appliance coupler
is used as the disconnect device, the disconnect
device shall remain readily operable.

This apparatus does not exceed the Class A/
Class B (whichever is applicable) limits for radio
noise emissions from digital apparatus as set out
in radio interference regulations of the Canadian
Department of Communications.

limites applicables aux appareils numériques de
class A/de class B (selon le cas) prescrites dans le
règlement sur le brouillage radioélectrique édicté par
les ministere des communications du Canada.

WARNING – To reduce the risk of fire or electric
shock, do not expose this component to rain
or moisture.

Congratulations on your purchase of an NXG

NX-BAS-500 powered subwoofer. It will give
your stereo, or home theater system unparal­leled low frequency output.

Bass frequencies are critical to realistic sound
reproduction. After you’ve hooked up your NX­BAS-500 subwoofer, you’ll discover just how
much “punch” and depth you’ve been missing.
No matter what kind of music or videos you lis­ten to... whether you listen to it loud or soft, you’ll
experience sound that’s richer and fuller. Bass
guitar and string bass will have more impact.
You’ll be able to FEEL as well as hear percus­sion – just the way you would at a live perfor­mance. If you have an audio/video system,
movies will come alive with thunderous sound
effects that were never possible without the NX­BAS-500.

The NX-BAS-500 is a self-powered subwoofer
that frees your receiver or power amplifier from
the power demands of reproducing very low
frequencies. To do this, the NX-BAS-500 incor­porates its own built-in crossover system that
automatically “assigns” lower frequencies to its
own power amplifier, contained within the sub­woofer enclosure.

The NX-BAS-500 has been meticulously
designed and tested to insure high perfor­mance, durability and longevity.

This manual is designed to take you step-by­step through the hook-up and operating
process. This procedure is not difficult, but it
slightly different than hooking up a line level
component such as a cassette deck or DVD
player. Reading this manual carefully will
insure that you get maximum performance
from your NX-BAS-500.

user to the presence of uninsulated “dangerous voltage” within the product’

A. UNPACKING

Remove the NX-BAS-500 from its packing
carefully and inspect it for any shipping damage.
If you discover damage, contact your NXG deal­er or installer immediately.

If possible, save the carton and internal pack­ing. It’s the best possible protection for your
NX-BAS-500 if you need to move it or return it
for service.

Keep your sales receipt in a secure place. It
helps establish the duration of your warranty
and is good for insurance purposes (just in case
anything happens to your stereo/home theater
system).

PANEL TOUR

Before actual hookup, you should familiarize yourself
with the connections on the back of the NX-BAS-500,
as shown in Fig.1.

1. VOLUME CONTROL. Rotating this knob clockwise
increases the output level of the subwoofer. To start
out, make sure that the VOLUME is turned all the way
down (fully counterclockwise). Later, after some initial
listening tests, you can adjust the volume to your own
taste. However, care should be taken not to overdrive
the subwoofer to the point of audible distortion.

2. CROSSOVER FREQUENCY CONTROL. This con-
trol determines what lower part of the frequency spec­trum will be reproduced by the NX-BAS-500. It is a
“crossover” control. Rotating the knob sets the point
where all lower frequencies will be handled by the
subwoofer.

As a starting point, set the control around 80 Hz (con­trol half-way, pointing straight up) if you are using left
and right tower speakers, 100 Hz. with bookshelf
speakers, and 120 Hz. with small mini-speakers.

3. PHASE SWITCH. This switch is used to set the

subwoofer’s phase to either normal “0°” or reverse
“180°” (out of phase). Once you determine the place­ment of the NX-BAS-500, you will need to try both
positions of this switch for the best bass output for
your listening position. The physical location of your
subwoofer and main speakers determines the phase
setting that will sound best at your main listening
position. If this requires using the “180°” mode, don’t
worry, there is nothing “abnormal” about it.

4. POWER INDICATOR. When the amplifier is ON,
this indicator will be green. When the amplifier is in the
STANDBY mode, the indicator will be red.
