Before applying power
The AELITE Sub is available in two main power versions to enable this 
product to be used globally, one to operate from 220-240V AC line main
power and one from 110-120V AC line main power. Please ensure you have
the correct version that relates to your country’s main power before use.
NOTES: Our warranty does not cover damage caused by using the incorrect
version relative to the main power supply. 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 furnishing. 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
washbowl, basin, in a wet basement or swimming pool area.
Temperature- The subwoofer may not function correctly at extremely low or
freezing temperature. 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.
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.

Introduction 
						

							7. Phase switch
The normal setting for the phase is the 0º position. Switching to 180º will
change the subwoofer phase and vary the tonal quality of the bass, which is
also dependant on the location of the AESPRIT Sub relative to your main
stereo speakers
8. Line in jacks(RCA-type pin-plug)
Used to connect the subwoofer to the PRE-OUT jacks of the amplifier.
9. Line out jacks(RCA-type pin-plug)
Used to connect

							The AELITE Sub 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
subwoofer should be positioned in a corner of the room or near a back wall.
In certain circumstances the addition of a second AELITE 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 AELITE Subs 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. It should not be placed directly onto the floor since the
reflex port is firing to the ground. 
When positioned correctly ensure space is left to the rear of the subwoofer since all
operation switches are on the rear panel.
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. 
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 AELITE 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.

							3. For use with amplifiers not having either a subwoofer Out jack
or Line level pre-amp jack
Using speaker cable from the speaker terminals on your amplifier, connect
to the Hi-level speaker input terminals on the AELITE Sub, and then a 
further set of cables from the Hi-level 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.

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 AELITE Sub. The line level outputs on the AELITE Sub are then
connected back to the power amp (main) inputs on your amplifier. This
provides the greatest power handling for the stereo speakers.

							4. For use with televisions with a variable audio output.
Some of the latest televisions are equipped with variable audio out
puts. These can be connected directly to the line level inputs on the
AESPRIT Sub to enhance the bass response of the television’s built-in 
speaker.
OPTION: 
5. For use with two AELITE Subs
Using parallel speaker cables from the speaker terminals on your amplifier 
connect to the High level speaker inputs on the corresponding left/right
AELITE Subs.

							How to use 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 100 Hz) 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 example, 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. 50-60Hz, 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.

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.
