PLACEMENT OR POSITIONING
Your new subwoofer will work well in a variety of locations. However, placement in your listening room will
affect its performance. Since the wavelengths of sound reproduced by your subwoofer are large compared
to its size, those sounds are omni-directional in nature. This means that locating your subwoofer in relation to
your left and right main speakers will not affect the directional cues which they provide.
As a general rule, locating your subwoofer near the corner of the room will increase its overall output, but will
excite more standing waves in the room and may result in a more uneven response. Locating your subwoofer
along a wall will usually mean less acoustic output but a somewhat smoother response. A middle of the room
location would suggest the smoothest response with the least output capability. Of course, any location will
be a compromise between acoustic performance and the aesthetic blend of the subwoofer enclosure with
the decor and furnishings of your room. Don’t be afraid to experiment with the location of your subwoofer in
your room for the best results at your listening position. As with any other listening test, use program material
that you are familiar with that has substantial bass content.
CONTROL FUNCTIONS (FIGURE A)
1. Polarity Switch: This two position switch allows the best match of acoustic output between the subwoofer
and the main stereo speakers in the region of the crossover frequency between them. The “normal”
position maintains phase from input to output, the “reverse” position changes polarity or phase by 180
degrees.
2. Power Switch: This three position switch controls the power status of the subwoofer.
Off: Turns the unit off.
Auto: Places the unit in the standby mode, in this mode the subwoofer will automatically turn on when an
audio signal is applied to either the high or low level inputs.
On: Turns the unit on regardless of whether a signal is present or not.
3. Subwoofer Crossover : This rotary control adjusts a variable low pass filter to set the upper frequency at
which the output of the subwoofer begins to roll-off. Continuously variable from 60 Hz to 180 Hz, it matches
the upper frequency characteristics of the subwoofer to the low frequency response of the main stereo
speakers.
4. Speaker Level: These banana jacks provide a speaker level, stereo output of the full range signal input.
5. Line Input: These banana jacks accept a line level full range signal from the preamplifier output of a
receiver or preamplifier. This full range signal is processed and amplified to power the subwoofer.
6. Speaker Level Input: These terminals for speaker wire accept a stereo, speaker level, full range signal from
a receiver or power amplifier. This signal is processed and amplified to power the subwoofer.
7. Fuse: For continued protection replace fuse with same type and size listed.
8. Level Control: This rotary control adjusts the level of the subwoofer and is used to balance its volume with
that of the main stereo speakers.
9. Status LED: This two color light emitting diode shows the status of the subwoofer electronics. “Red”
indicates that the amplifier is plugged in and the power switch is either off or in standby mode with no input
signal present. “Green” indicates that the amplifier is operating with signal present at the input from the
preamplifier, receiver, or power amplifier.
10. Main Power Switch: This switch controls the overall power status of the subwoofer. Must be in the on
position to operate.
11. Voltage Selector: Select for 115V or 230V operation.
