INTRODUCTION
We are proud to welcome you as a new owner of an ENERGY Speaker System.
ENERGY speakers are the result of extensive research into accurate sonic reproduction
and represent the leading edge in speaker design and performance. The finest components
and cabinet materials combined with sophisticated manufacturing and quality control
procedures ensure many years of exceptional performance and listening pleasure.
Please take time to read all of the instructions contained in this manual to make certain
your system is properly installed and functioning correctly.
Be sure to unpack your system carefully. Retain the carton and all packing material for
future use.
SUBWOOFER CONNECTION TO YOUR
AUDIO/VIDEO SYSTEM
There are essentially two methods by which you can connect your ENERGY subwoofer to
your audio/video system. The first is "The High Level Connection" and the second,
"The Low Level Connection". Your system components will dictate which method to
use, but High Level Connection can be used with virtually any receiver or amplifier.
CAUTION: (A) DO NOT USE BOTH LOW LEVEL AND HIGH LEVEL METHODS
SIMULTANEOUSLY. (B) TURN OFF ALL POWER IN YOUR STEREO SYSTEM BEFORE
PROCEEDING WITH THE INSTALLATION OF THE SUBWOOFER.
Using High Level Connections (see Diagram 1)
On the rear of your ENERGY subwoofer cabinet is a block designated "High Level". This
block contains two pairs of speaker terminals. These should be connected to the speaker
output terminals of your amplifier or A/V receiver. Each pair of terminals are color coded
black/red.
NOTE: These terminals will accept up to 18 Gauge speaker wire.
REMEMBER: Always connect red-to-red and black-to-black, when making the
connections between amp/receiver to subwoofer. If you inadvertently reverse one of the
connections (ie. red-to-black), you will notice a lack of bass from your subwoofer.
Using the "Subwoofer Output" of an A/V Receiver or
Processor (See Diag. 2 - Low Level Connection1)
This method uses a single RCA-to-RCA interconnect cable to connect the "SUBWOOFER
OUTPUT" jack from your A/V receiver or processor to the subwoofer "INPUT". This
method does not remove low frequencies from your main speakers, and they will continue
to reproduce bass frequencies.
Using An External Crossover
(See Diag. 3 Low Level Connection 2)
This method uses a single RCA-to-RCA interconnect cable to connect the "SUBWOOFER
OUTPUT" jack from an external crossover to the "XOVER INPUT" of your subwoofer.
This method by-passes the subwoofer's built-in level and crossover controls; subwoofer
functions are controlled by the external crossover. (See External Crossover Owner's Manual
for details.)
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 to its zero position. Set the Subwoofer LP Filter
Control to 50Hz. Set any loudness, bass/treble, and/or equalizer controls on your
preamplifier or integrated amp/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 clockwise until you achieve a neutral
balance between the subwoofer's deep bass output and your main/satellite speakers.
4.
Slowly turn the Subwoofer LP Filter Control 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 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 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 main amplifier or receiver.
