VX-11 User’s Manual
Placement
Subwoofers operate at extremely low frequencies that are primarily omni-directional. Keep in
m
ind that frequency response and output level can be
d
rastically
i
nfluenced by placement,
depending on the acoustic properties of the listening room. Typically, the optimum location for
a subwoofer is tucked away in a corner of your listening room where the greatest output levels
and optimum low frequency extension can be found. The worst location for a subwoofer is far
away from any walls and close to the center of your room. Avoid these locations when possible.
Depending on the room size and type of furnishings in the room, perfect placement may not be
possible. Finding the best location for your environment will likely require some experimentation.
We suggest you experiment with the location during setup to find what sounds best to you when
seated in your typical listening position.
Caution! This subwoofer has electronics built into the cabinet. Do not place the cabinet
next to sources of heat such as furnace registers, radiators, etc., or near sources of
excessive moisture such as evaporative coolers, humidifiers, etc. The power cord should
be routed in such a way that it will not be walked on, pinched, or compressed in any
way that could result in damaging the insulation or wire.
Regardless of where you install your VX-11 subwoofer, it must remain in an upright position
(woofer facing forward). Using, shipping, or otherwise storing the subwoofer in any other
position for an extended period of time may result in damage to the unit not covered
by warranty.
Inputs
Your new subwoofer is equipped with speaker
-level and line-level inputs. Use the
LINE LEVEL
jacks when connecting your subwoofer to a pre-amp, signal pr
ocessor, integrated receiver,
line-level crossover, or receiver with pre-amp level outputs. These devices will often have a Low
Frequency Ef
fects (LFE) jack which is dedicated for subwoofer use. When using the line level
jacks, some r
eceivers may not provide enough signal to have the unit’s auto-on feature operate
pr
operly. Additionally, this lack of signal may also cause the subwoofer to produce less output
than it is capable of.
To alleviate this condition, we recommend the following steps:
1) If using line level jacks, BOTH THE LEFT AND RIGHT INPUT SHOULD ALWAYS BE USED
– never use just the left or just the right input. If the subwoofer’s input comes from the
LFE channel of your r
eceiver
, use a “Y” splitter to divide the single input into two inputs
for the Left and Right subwoofer inputs. This dual male-to-female “Y” splitter can be found
at your local electr
onics stor
e. If using line level connections from a preamp or signal
pr
ocessor, use both Left and Right inputs from your preprocessor or preamp and
connect them to the Left and Right inputs on your subwoofer.
2) If using a receiver with LFE out, be sure the LFE channel is sending adequate signal to
the subwoofer. We recommend setting the subwoofer’s level to the 9 o’clock position
(the 1/4 volume setting) and then adjust the LFE channel on your receiver or processor
to achieve the desir
ed bass output. See your r
eceiver or pr
ocessor’
s owner’s manual for
more information.
