METHOD 2 – 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
r 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.
2 After connecting the
r 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 subwoofer
into an AC outlet. Do not use the AC outlet on the rear of your receiver.
3 See Final System Adjustments, below.
FINAL SYSTEM ADJUSTMENTS
1 After having turned on the main power switch and having broken-in the
speaker, select the correct position for the
a POWER MODE, 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.
2 Adjust the
p VOLUME LEVEL of your ENERGY 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
i LOW-PASS FILTER on your ENERGY subwoofer so that the
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 120Hz, for the
bookshelf speakers 70Hz to 90Hz and for the large floorstanding speakers
40Hz to 70Hz.
4 Adjust the
o 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 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.
