3. Crossover Control - This control allows for the adjustment of the low-pass
filter. Adjustments can infinitely be made from 50Hz to 110Hz. This will
determine the highest frequency that the subwoofer will play.
4. Phase Control - This allows for the
infinite adjustment of the phase of
the subwoofer, in relation to the
speakers used in your system, from -
180 degrees to + 180 degrees.
5. Power Mode - This switch can be
set to either On, Off or Auto. If the
switch is in the Off position, the
subwoofer will not power up. If the
switch is in the On position, it will
constantly remain on. If the switch is
set to the Auto position, when a
signal is present the subwoofer will
turn on and will automatically turn
off several minutes after a signal is no
longer present.
6. X-Over Mode - This switch allows
for the selection of either X-Over
Mode (A) Crossover Activated or (B)
Crossover Bypassed. (Please see the
connections section for suggestions
on which mode is appropriate for
your installation.)
7. Sub In - This input is an RCA type
mono input.
8. High-Level Input - These are 5-way binding post type speaker connectors. The
High-Level inputs are designed to be used on receivers or amplifiers that do not
incorporate any RCA type subwoofer outputs. If your receiver IS eqUipped with
an RCA type subwoofer output, these speaker level inputs should not
be utilized.
CONNECTING YOUR
ENERGY SUBWOOFER
CAUTION: All power should be turned off to your system before any
connections
are made. Careful attention should be taken to ensure that all
electronic components
are not connected to an AC source. Not doing so
could result in potential damage to the system.
There are two mutually exclusive methods to connect your subwoofer to your
receiver.
Method 1 - RCA - For Home Theater or lFE Applications
1. On the rear of the receiver there should be a single RCA type jack marked
"Subwoofer Out". Connect a single RCA cable from that jack to the RCA Sub In
(#7) on the rear of the subwoofer. A standard male to male RCA cable is
needed.
2. After connecting the single low level Sub In (#7) connection, plug your
ENERGY~ subwoofer into an AC outlet. Do not use the AC outlet on the rear of
your receiver.
3. Select either the X-Over Mode (A) or (B) (#6). The X-Over Mode (A) "Crossover
Activated" switch position should be used when connecting your ENERGY~
subwoofer to a receiver without bass management or when you wish to
manually control the crossover and volume settings (such as in a music system).
The X-Over Mode (B) "C rossover Bypassed" switch position should be used
when connecting to a receiver with bass management (such as in a digital
surround sound movie system). This connection defeats the crossover feature
on the ENERGY~ subwoofer, allowing this control to be handled by the receiver.
Adjusting the front panel Volume Control (#1) will still be required.
4. Ensure that the supplied vibration dampeners are installed in the high-level
speaker inputs, as this ensures that the inputs will not vibrate audibly.
5. See Final System Adjustments, below.
Method 2 - Speaker level - For Music Applications
1. The other way to connect your subwoofer to your receiver is using a High-Level
(#8) (speaker wire) connection, by simply connecting the speaker wires from the
Front Left and Right Speaker Outputs on your receiver to the Left and Right
Inputs on the rear of the subwoofer (#8). It is imperative that speaker polarities
owners manual
be maintained, one must connect the positive and negative wires to the
appropriate positive and negative terminals. Failure to do so will result in an out
of phase connection, severely limiting the amount of bass in your system.
2. After connecting the High-Level (#8) (speaker wire) between your receiver and
subwoofer, ensure no fray wires are touching, as this could cause a short circuit
and damage your electronics. Plug your ENERGY~ subwoofer into an AC
outlet. Do not use the AC outlet on the rear of your receiver.
3. See Final System Adjustments, below.
Do NOT connect both RCA and High-Level connections simultaneously, as
this will damage your ENERGY subwoofer.
FINAL SYSTEM ADJUSTMENTS
1. After having turned on the main power switch and having broken-in the
speaker, select the correct position for the Power Mode switch (#5), either On
or Auto depending on your system. The Auto selection will leave the unit in a
self-sensing mode, such that should the unit sense an audio signal it will turn
itself on and then shut down after several minutes without signal, while in the
On position the subwoofer always remains on. Should the system not be used
for an extensive period of time, it is recommended that the subwoofer be
unplugged from the AC outlet.
2. Adjust the Volume Control (#1) on the front panel of your ENERGye subwoofer
so that the volume of your subwoofer matches the overall system volume. This
ensures a smooth transition between the low and high frequencies of
your system.
3. Adjust the Crossover Setting (#3) on your ENERGye Speakers subwoofer so that
the frequency range of the subwoofer blends well with that of the front .
speakers (For use with all settings, except when in X-Over Mode (B)). Setting
the crossover too low will create a gap between the frequency response of the
front speakers and that of the subwoofer, while setting the crossover frequency
too high will create a doubling of certain frequencies, making the music sound
boomy. When using small satellite speakers, the appropriate crossover
frequency should be from 90Hz to 110Hz, for the bookshelf speakers70Hz to
90Hz and for the large crossover floorstanding speakers 50Hz to 70Hz.
4. Adjust the Phase control (#4) so that the subwoofer integrates fully with the rest
of your audio system. This control is infinitely adjustable and ensunng that the
subwoofer operates in phase with the rest of the system is critical, as an out of
phase subwoofer will either sound like it is lacking in bass performance or that
its timing is off. This setting will be determined by your listening position, the
characteristics of your listening room and its interaction with your ENERGY~
subwoofer. An out of phase speaker means that the speaker cone is moving
inwards when it should be moving outwards, like the other speakers in your
system, causing cancellations of certain frequencies. By adjusting the phase
control, one can ensure that all speakers move in the proper direction, at the
same time.
5. Steps 2,3 and 4 might require repeating in order to fine tune your system.
Ensuring the proper blending between the speakers and the subwoofer is critical
to the performance of your system, as a whole.'
