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.

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).

B. AMPLIFIER
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.

C. PLACEMENT
Where to position your
NX-BAS-500
The NX-BAS-500 operates at low bass frequencies
which are essentially omni-directional. That means
you can place the NX-BAS-500 almost anywhere
in a room without compromising the effectiveness
of your main stereo speakers.
Four factors need to be considered:
1) distance from your main speakers;
2) distance from a wall outlet;
3) distance from your receiver, amplifier,
or flat panel TV; and
4) proximity to walls and corners.
1. Distance from your main speakers. The best
placement for your subwoofer is on the same wall
as the main speakers, especially if you are matching up with small bookshelf speakers. With tower
speakers, side wall or rear placement is also
acceptable.
2. Wall outlet. Since the NXG subwoofer requires
AC power, it must be placed where it will reach a
wall outlet. We don’t recommend extending that
range with an extension cord.
3. Connections to your receiver, amplifier, preamplifier or flat panel TV.
nect the subwoofer to your receiver subwoofer output or LFE output, flat panel TV, or preamp line
level outputs (see next page). You can basically
place the NX-BAS-500 anywhere in a normal-sized
room.
4. Proximity to walls and corners. Physical
placement of the subwoofer will have a definite
impact on the frequency response and the perceived amount of NX-BAS-500 bass output.
Because low frequencies have long wavelengths,
they are influenced by proximity to a boundary
such as a wall or floor
You will need to con-
.
All this technical jargon may sound confusing, but it basically means that you have a number
of options, each of which produces a different amount of bass. For example, if you like a lot of
heavy bass, consider putting the NX-BAS-500 into a corner. If you like smoother, less-obvious
bass, move the subwoofer out into the room. The main thing to remember is that there is no
“right” or “wrong” place to put the NX-BAS-500. It all depends on how much bass you want.
Another reason to experiment – because low bass waves are very large (up to 40 feet or more
across!), they tend to cancel and reinforce each other, causing places in the room where there
is lots of bass and others where there isn’t very much at all. If you walk around your listening
room while playing music, you’ll probably discover these sorts of areas where bass is either
exaggerated or reduced. Needless to say, if your main listening area ends up in a “dead” space,
you will need to move the NX-BAS-500 so that bass is more normal.
Incidentally, moving the NX-BAS-500 around won’t affect the stereo imaging of your main
stereo system, so feel free to try various subwoofer positions.
Away from walls:
Normal bass
Against walls:
More bass
FIG. 2 - NX-BAS-500 placement
In corner:
Most bass
Connecting to a wall plug
The NX-BAS-500 draws a moderately high amount of current. We do not recommend plugging
it into a “convenience” outlet (switched or unswitched) that is often found on the back of
receivers and other stereo components.
Instead, connect the subwoofer ONLY to its own AC outlet. See items 7 and 8 in the Safety
Instructions on Page 2 of this manual.
See Fig. 2. When you place the NX-BAS-500 well
away from a wall, it will produce bass at a certain
level. Move the subwoofer close to the wall, it will
produce more output (about 3dB more). Putting the
subwoofer in a corner will increase output another
3dB (6dB more than when placed away from walls
and corners).
D. CONNECTIONS
Three basic connection options
1. Connection to electronics with subwoofer or LFE output. If you own a surround sound
receiver or integrated amplifier with a subwoofer or LFE output, use Method A as shown
in Fig. 3.
2. Connection to stereo preamp and amplifier.If you have separate preamp and amplifier
use Method B as shown in Fig. 4.
3. Connection to flat-panel TV. If you have a flat panel TV with stereo analog audio outputs,
use Method C as shown in Fig. 5.
,
Method A: Line level hookup steps for receivers with subwoofer connections
(Refer to Fig. 3 below)

Note: This connection method is only for receivers that have a
subwoofer or LFE output. You will need one line level RCA to RCA connector cable long enough to reach from your receiver to your NX-BAS500 location. This should be available from your NXG dealer or from
radio supply stores.
1. IMPORTANT: Make sure that ALL system components including
the NX-BAS-500 are turned OFF before proceeding.
Locate the subwoofer or LFE output connector on the rear of your
2.
receiver and connect one end of the RCA line level cord to it.
3. Route the line cord to the subwoofer location (trying to minimize

areas where it may be stepped on) and connect the other end directly
to the sub’s LINE IN R or LFE input.
4. Connect your main (and surround speakers if applicable) to the
receiver according to the receiver’s owner’s manual.
5. Note: If you are using a Dolby Digital type receiver with built-in crossover, you must set the crossover frequency in your receiver (check your
receiver’s owner’s manual). Set the subwoofer’s crossover to 120 Hz.
6. You are now ready to put your NX-BAS-500 subwoofer into use.
Skip to “E – INITIAL LISTENING TEST.”

Method B: Line level hookup steps for systems with preamplifier and power amplifier
(Refer to Fig. 4 below)
1. IMPORTANT: Make sure that ALL system
components including the NX-BAS-500 are
turned OFF before proceeding.
2. Locate the LINE output RCA sockets on the
back of your preamplifier. These are typically
marked PRE, PRE OUT, LINE OUT or TO
POWER AMP, depending on the make and
model of component.
3. Connect a set of high-quality line level RCA
male to dual female Y-connectors to the preamp’s LINE OUT sockets. Then connect a
pair of high-quality line level cables from the Y
connectors to the left and right LINE IN of
your subwoofer. Make sure that left is connected to left and right is connected to right.
4. Connect another set of connection cables
between Y-connectors and the MAIN INPUTS
of your power amplifier. Again, make sure that
left is connected to left and right is connected to
right.
5. Connect your main speakers to the speaker
terminals on the back of your power amplifier.
6. You are now ready to put your NX-BAS-500
subwoofer into use. Skip to “E – INITIAL

E. INITIAL LISTENING TEST
It’s now time to introduce the NX-BAS-500 amplifier’s potent and plentiful
bass into your listening environment.
1. Double-check all connections.
ake sure that the volume controls on both the NX-BAS-500 and
2.M
our receiver/integrated amp/preamp/TV are turned all the way down
y
fully counterclockwise). Set the PHASE switch to zero. Set the CROSS-
(
VER FREQUENCY knob to 80 Hz for normal operation, or to 120 Hz for
O
Dolby Digital operation where the proper crossover frequency is set in the
receiver’s crossover.
3. Turn on your stereo/home theater system. THEN turn on the NX-BAS-
500. Confirm that the subwoofer’s green POWER indicator is glowing. If it
isn’t, check the power connections between the NX-BAS-500 and the wall
socket.
4. Play a musical selection or DVD that you are familiar with. Pick a
song that has regular low bass beats. Advance the receiver/ integrated
amp/preamp/TV’s volume control up to a normal listening level. If you
don’t hear sound through your main speakers, turn off the system and
check connections. Also consult the troubleshooting tips on page 8.
5. If sound is indeed coming out of your main speakers, turn the NX-BAS
500’s VOLUME control clockwise until you hear noticeable additional
bass. If you don’t hear bass by the time you have advanced the subwoofer’s VOLUME control halfway, turn off the system and check connections. Also consult the troubleshooting tips on page 8.
6. Adjust the NX-BAS-500’s VOLUME control until you are satisfied with
the amount of bass. You may want to try several different albums, compact discs, or DVDs while determining how high to adjust the NX-BAS500’s VOLUME. The amount of bass varies from CD to CD and DVDs.
7. Now that you have adjusted the quantity of bass via the volume, it’s time
to work on the quality of the bass with the CROSSOVER FREQUENCY
control, PHASE switch – and experimentation with NX-BAS-500 room
position.
• While playing music or a movie, move the subwoofer around, in and out
of corners, closer and farther from the wall, etc. as much as the power
cord and other connections will allow.
• Change the PHASE switch between 0° - 180°, while someone sits
in the main listening position. Leave the switch in the position where you
like the bass most.
• Change the CROSSOVER FREQUENCY control (for Dolby Pro-Logic
receivers) to higher and lower settings. If the CROSS-OVER FREQUENCY
control is set too high, you’ll start to hear low midrange (voices and
instruments) through it. This will negatively affect the stereo imaging of
your main speakers. Lower the CROSSOVER FREQUENCY setting until
you hear only bass from the NX-BAS-500. If the CROSSOVER FREQUENCY control is set too low, you simply won’t get much output from
the subwoofer. Move it back closer to 80Hz.
8. After you are satisfied with the output of your NX-BAS-500, you can
make all your volume settings through your main stereo system’s volume
control. The only time you might want to re-adjust the NX-BAS-500’s VOLUME is when you encounter a musical selection or movie that has abnormally low – or high – bass.
You can leave the NX-BAS-500 turned on and in AUTO mode when not
in use. It does not draw much power in this state and will be ready to add
low bass the moment you begin to play music.
Remember, you don’t have to do anything except leave the POWER switch
in the AUTO position. The NX-BAS-500 will automatically go into STANDBY
mode after approximately 5 minutes, when no music or movie is playing.
If you’re not using your system for a long period of time (such as when
you’re on vacation), turn the MASTER POWER switch to the OFF position.

Caring for Your
NX-BAS-500
The NX-BAS-500 enclosure is finished
in a very high-quality polyurethane finish that is both attractive and excellent
protection for the wood cabinet. To
remove dust, finger prints, and light
water marks you can use a soft, dry
cloth. Never use a solvent like paint
thinner, Ketone, gasoline, MEK, lighter
fluid, etc., on the enclosure surface or it
will cause permanent damage.

B
an save time (and often embarrassment) by checking
c
or a few problems that are most often encountered.
f
Power light is not lit. No sound.
1. Is your NX-BAS-500 plugged in to a live AC wall
socket?
2. Is the power switch on?
3. Has the NX-BAS-500 overheated and shut off
temporarily?
No sound from either set of speakers.
1. Are your other components turned on?
2. Is the receiver, preamp, or TV set to the appro-
priate input and is that sound source playing?
3. Do you have an unconnected tape monitor
selected?
4. Is the NX-BAS-500 correctly connected to your
receiver, preamplifier, integrated amplifier, or TV
and turned on?
Sound comes from main speakers but not the
subwoofer
1. Is the NX-BAS-500 turned on (power light in the
green mode) and VOLUME control turned up?
2. Check the speaker connections for small strands
of wire touching both terminals.
3. Some digital receivers only send a sub out signal
when in the movie or digital mode. In the 2 channel
(stereo music) mode, no sub out signal is sent to
the sub.
You may need to set your main speakers to “small”
mode in your receiver setup to get the receiver’s
subwoofer output to turn on. Check your receiver’s owner’s manual for subwoofer operation.
4. For digital receivers – make sure the subwoofer
is “ON” and the subwoofer level is set to “0dB”
or greater.
Sound comes from the subwoofer but not your
main speakers
1. • Confirm that the power amplifier is turned on.
• Check the RCA patch cord
• Check the speaker wire connections between
the receiver and main or satellite speakers.
Bass is muffled or weak
1. Check speaker wire polarity of all connections.
2. Reposition your subwoofer. At some points in
the room, its output may be cancelled by the
geometry of the room. Moving the NX-BAS-500
can eliminate this problem.
Please refer to Item 10 in the Safety Instructions
for conditions that ALWAYS require service by
qualified personnel.
If you have tried all the above and still cannot
get the NX-BAS-500 to operate properly,
consult your dealer or contact NXG tech support
