NXG Technology NX-BAS-500 - Manual (Page 4)

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.
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.

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 match-
ing 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, pre-
amplifier or flat panel TV. You will need to con-
nect the subwoofer to your receiver subwoofer out-
put 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 per-
ceived 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.
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).
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.
