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.
METHOD 1 – RCA – SUB IN FOR HOME THEATER OR LFE
APPLICATIONS
1 On the rear of the receiver/pre-amp there should be a single RCA type jack
marked "Subwoofer/Pre-Amp Out". Connect a single RCA cable from that
o
jack to the LINE IN/SUB IN on the rear of the subwoofer. A standard male
to male RCA cable is needed.
o
2 After connecting the single
ENERGY ® subwoofer into an AC outlet. Do not use the AC outlet on the rear
of your receiver. After plugging in the unit, switch the Main Power to On.
3 See Final System Adjustments, below.
METHOD 2 – RCA – LINE IN FOR STEREO APPLICATIONS
1 On the rear of the receiver/pre-amp there should be stereo (left and Right)
RCA type jacks marked "Left and Right Pre-Amp Outputs". Connect a pair of
RCA cables from those jacks to the
subwoofer. A standard male to male RCA cable is needed.
o
2 After connecting the stereo
ENERGY ® subwoofer into an AC outlet. Do not use the AC outlet on the rear
of your receiver. After plugging in the unit, switch the Main Power to On.
3 See Final System Adjustments, below.
METHOD 3 – SPEAKER LEVEL – FOR MUSIC APPLICATIONS
1 The other way to connect your subwoofer to your receiver is using a 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
p
SPEAKER LEVEL IN on rear of the subwoofer. It is imperative that speaker
polarities 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.
p
2 After connecting the SPEAKER LEVEL IN (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
into an AC outlet. Do not use the AC outlet on the rear of your receiver.

FINAL SYSTEM ADJUSTMENTS
1 After having turned on the main power switch and having broken-in the
speaker, select the correct position for the
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.
r
2 Adjust the VOLUME LEVEL of your ENERGY
volume of your subwoofer matches the overall system volume. This ensures a
smooth transition between the low and high frequencies of your system.
t
3 Adjust the LOW-PASS FILTER on your ENERGY
frequency range of the subwoofer blends well with that of the front speakers.
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 150Hz, for the
bookshelf speakers 70Hz to 90Hz and for the large floorstanding speakers
40Hz to 70Hz.
u
4 Adjust the PHASE CONTROL so that the subwoofer integrates fully with
the rest of your audio system. This control ensures that the subwoofer
operates in phase with the rest of the system, 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
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.
