Before applying power
The AEGIS Compact Sub is available in two mains power versions to enable
this product to be used globally, one to operate from 220–240V AC line mains
power and one from 110–120V AC line mains power. Please ensure you have
the correct version that relates to your country’s mains power before use.
NOTES:Our warranty does not cover damage caused by using the incorrect
version relative to the mains power supplied. The grille is designed to protect
the bass unit from possible damage and should not be removed.
Please read all operating and safety instructions before use retaining them for
future reference. Adhere to all warnings on the product or in this manual.
Power sources — the subwoofer should be connected only to a power supply of the
type described on its rear panel. If you are not sure consult your dealer or a
qualified electrician.
Power cord— Power supply cords should be routed so as not to be walked on or
caught under or against items.
Ventilation— To ensure reliable operation and to prevent the subwoofer from
overheating ensure good ventilation. Do not cover the subwoofer and do not place
it closer than 10cm from walls or soft furnishings. Do not use in a built-in
installation unless proper ventilation is provided. Consult your dealer.
Water and moisture— The subwoofer should not be used near water, i.e near a
wash-bowl, basin, in a wet basement or swimming pool area.
Temperature — The subwoofer may not function correctly at extremely low or
freezing temperatures. The subwoofer should also be sited away from heat sources
such as radiators or other electrical equipment that produces heat, including other
amplifiers.
Electric shock— Care should be taken so that objects are not inserted into
connectors or other apertures and that liquid does not spill into the enclosure. Do
not insert objects into the reflex port.
Never attempt to dismantle the subwoofer as serious electric shock might occur if
the internal parts are touched.
Cleaning— Unplug the subwoofer from the wall power outlet before cleaning. Use
only a clean, dry cloth. Do not use cleaners, liquids or solvent based preparations to
clean the cabinet.
Smells— If an abnormal smell or smoke is detected, immediately turn the power
Off and unplug the subwoofer from the wall power outlet.

							The AEGIS Compact Subwoofer is virtually omni-directional, so it can be
positioned in almost any location in the room. For the best performance in the
ideal room the AEGIS Compact Sub should be positioned in a corner of the
room or near a back wall. In certain circumstances the addition of a second
AEGIS Compact Sub located in another position in the room helps to achieve
a more uniform bass.
The use of two subwoofers often provides a greater than expected increase in
sound quality and bass dynamics, worth more than the additional cost would
suggest. If two AEGIS Compact Subwoofers are used they should ideally be
positioned in the corners near the respective units of the stereo loudspeaker
pair.
This subwoofer may be installed using the four rubber feet or spikes with lock
nuts, both supplied. Alternatively it may be placed directly onto the floor.
When positioned correctly ensure space is left to the rear of the AEGIS Compact
Sub since all operation switches are on the rear panel.
Connections
Check that both your amplifier and subwoofer are switched off before
connection. Failure to do so may result in speaker or amplifier damage. It is
sometimes recommended that over-long low cost cables are used initially to
facilitate experimentation with positioning, and only then purchase and install
using the final cable choice.
(For best results we would recommend our own AESC-C3 high performance
speaker cable with any Acoustic Energy loudspeaker.)
1. 
For use with amplifiers having a Subwoofer Out jack
Connect from the dedicated subwoofer line output on the amplifier to the
line input(s) on the AEGIS Compact Sub. (A single lead to either input or a
‘Y’ connector to both inputs may be used). The stereo speakers are run
direct for higher definition.

2. For use with amplifiers having Line level pre-amp jacks
The pre-amp outputs of your amplifier can be connected to the line level
inputs on the AEGIS Compact Sub. The line level outputs on the AEGIS
Compact Sub are then connected back to the power amp (main) inputs
on your amplifier. This provides the greatest power handling for the stereo
speakers.
3. 
For use with amplifiers not having either a Subwoofer
Out jack or Line level pre-amp jacks
Using speaker cable from the speaker terminals on your amplifier, connect
to the Hi-level speaker input terminals on the AEGIS Compact Sub, and
then a further set of cables from the Hilevel output terminals to your main
stereo/satellite speakers.
(The stereo speakers receive the original amplified signal minus the
frequencies used by the subwoofer). This provides greatest power
handling for the system with good overall performance.

							How to use the controls
How to use the SUB VOLUME CONTROL knob, CROSSOVER FREQUENCY
knob and PHASE switch
The VOLUME CONTROL, FREQUENCY knob and PHASE switch can be
adjusted to match the condition of the listening room and/or the
characteristics of the left and right front speakers.
Due to the positioning of the subwoofer in the room and the associated room
boundaries, the available bass response from the existing speakers and
whether or not the filtered connection (nominally 100Hz is used), the actual
settings used on the subwoofer control panel will vary considerably.
The SUB VOLUME CONTROL and the CROSSOVER FREQUENCY knobs should
be used together when setting the correct bass response required. For ample,
raising the volume level will also raise the effective system crossover point,
while reducing the volume has the converse effect of lowering the frequency
range of the subwoofer. This is caused by the way the various responses and
outputs blend together in the listening environment.
Initially set the crossover frequency fairly low, e.g 50 – 60 Hz, and use the
volume control knob on the sub to set the low bass level required. When the
correct balance is almost achieved, the crossover level, volume level and phase
setting may be adjusted together to fine tune the sound and achieve the
cleanest, most extended and suitably powerful bass.
The ideal is for a seamless blend of extended low bass from the subwoofer leaving
the clean upper bass response of the stereo system largely undisturbed.
Typical Control Positions
FRONT SPEAKER CROSSOVER PHASE SUB LEVEL
Large speaker 40 – 60 Hz Normal 0°
Medium speaker 60 – 80 Hz Normal 0°
Small speaker 80 – 100 Hz  Normal 0°
CAUTION
An excessive input level to the subwoofer may impair the sound
quality or damage the unit. Do not increase the output of the
amplifier to a high level while the low-frequency level is
enhanced by the amplifier’s tone control or loudness control.
