SET UP CALIBRATION

For best results when setting up your system, assume your normal listening position and have
another person perform the following adjustments:
1. Set the Subwoofer Level Control (BL) to its zero position. Set the Subwoofer Low Pass
Filter Control (LPF) to its lowest setting (50Hz). Set any loudness, bass/treble, and/or
equalizer controls on your Processor or Receiver to their normal or mid-point
positions.
2. Play a familiar CD, record, or video soundtrack that has substantial bass content.
3. Gradually turn the Subwoofer Level Control (BL) clockwise until you achieve a neutral
balance between the subwoofer's deep bass output and your main/satellite speakers.
4. Slowly turn the Subwoofer Low Pass Filter Control (LPF) clockwise to reach the best
mid bass blend with your main/satellite speakers.This will be the point at which the bass
retains solid impact and fullness.
If the mid bass becomes "boomy" or ill defined, you have gone too far and should turn the
LPF control counter-clockwise to the best balance point. If the sound is too thin
(i.e., male vocals are not full sounding) then turn the LPF control clockwise to the best
balance point.
NOTE:The Subwoofer Level Control is designed to control the balance between your
subwoofer and main/satellite speakers and should not be used as a substitute for the bass
or loudness controls on your amplifier or receiver. Adjust the subwoofer's level for
smoothest low frequency performance. If more bass is desired, then advance the bass
and/or loudness controls on your amplifier or receiver.
SUBWOOFER FEATURES
Auto-On/Auto-Off Circuit
Your subwoofer is equipped with a special "Auto-on/Auto-off " circuit.This circuit
automatically turns your subwoofer on as soon as it senses a program signal. At a
predetermined time after the program signal ends, this circuit automatically turns the
subwoofer off.
Clipping Protection Circuit
Many powered subwoofers on the market produce distorted sounds as a result of clipping
at high input levels.The proprietary ENERGY Clipping Protection Circuit (CPC)
continuously senses the input signal level and automatically adjusts to prevent clipping of the
waveform, maintaining undistorted bass reproduction.
High Level Input and Output Terminals
The High Level inputs allow you to connect your subwoofer to the speaker outputs of any
A/V Receiver or power amplifier.The outputs facilitate easy connection of a set of passive
speakers. See "Subwoofer Connection to your Audio/Video System".
Low-Level RCA Input Jacks
The two RCA Input jacks allow you to connect your subwoofer to EITHER:
1) The subwoofer mono output of an A/V Receiver/Processor OR
2) The subwoofer output of an External Crossover.
NOTE:When using the External Crossover Input, the Subwoofer Level Control (BL) and
Low Pass Filter Control (LPF) on the subwoofer's rear panel are bypassed and have no
effect on the subwoofer.
Power Switch
The rear mounted power switch will turn off the AC power to the subwoofer. If you will not
be using the subwoofer for extended periods of time, it is recommended to turn the
subwoofer off.
SUBWOOFER OPERATING CONTROLS
BL - Subwoofer Level Control
This rotary control adjusts the output level of your ENERGY subwoofer and should be
used to balance the level of the subwoofer with that of your main satellite speakers. See
"Set-up Calibration".
LPF - Low Pass Filter Control
This rotary control adjusts the high frequency roll-off of the subwoofer. Continuously variable
from 50Hz to 100Hz, it is used to precisely match the subwoofer bass reproduction with
that of your main/satellite speakers. See "Set-up Calibration".
A/V - Audio/Video Switch
This switch is an equalizer that you may use at your discretion. In the Audio position, the
equalizer circuit is not engaged. However, in the Video Position, the equalizer is engaged. In
the video mode, the equalizer adds more punch to the frequency response, and is usually
beneficial during playback of movies. When listening to music, you will probably want to keep
this switch in the "Audio" position, however it is completely up to you to decide which
position the subwoofer sounds best in.
ROOM ACOUSTICS &
SUBWOOFER PLACEMENT
ENERGY subwoofers can be placed virtually anywhere in your listening room without
significantly affecting the stereo image of your main speakers. However, interactions between
any subwoofer and a room's acoustic properties will have some impact on the overall bass
performance.
Reading this section will help you to find a placement for the subwoofer in your room which
will yield the best bass performance.
CAUTION: ENERGY SUBWOOFERS HAVE A BUILT-IN AMPLIFIER AND MUST HAVE
ADEQUATE VENTILATION FOR COOLING PURPOSES. DO NOT PLACE THE
SUBWOOFER NEAR HEAT SOURCES, OR ANYTHING WHICH MIGHT OBSTRUCT
VENTILATION.
Although a clear path between the subwoofer and listening position is not required, it is
important to leave approximately 4 inches (10cm) of clearance between the subwoofer and
walls or room furnishings.
Generally, shorter runs of hook-up cables are also preferable (and easier to hide), therefore
locating your subwoofer relatively close to your audio equipment is often desirable.
The interaction between room acoustics and any subwoofer is closely related to the
subwoofer's proximity to the walls.Typically, subwoofer placement directly in or close to a
corner will produce the most bass output, placement along one wall but away from a corner
will produce less bass output, and placement of the subwoofer further into the room will
produce the least amount of bass output.
It should also be realized that the corner location, although producing the most bass output
often yields ill-defined or "boomy" bass.The latter two locations will deliver progressively
more accurate bass performance.
We urge you to experiment with various subwoofer placements in your listening room to
find the position which produces "deep and smooth" performance. Often, moving the
subwoofer a foot or two (30- 60cm) can make a big sonic improvement.
Remember to use familiar musical recordings with an abundance of low frequency
information when you experiment with subwoofer locations.
