3. Installation and Positioning  
Aego-T is a satellite and subwoofer loudspeaker  
system designed to be used in domestic audio and  
audio-visual (home theatre) systems. It comprises  
a compact passive satellite speaker and an active  
(powered) subwoofer. The satellite speakers may  
be used either placed on furniture or wall-mounted  
using the included brackets. The subwoofer should  
be used placed on the floor. Use of the satellite  
wall-brackets is described in Section 4.  
The location of the subwoofer is less critical but it should be placed a similar  
distance away from the listening position as the satellites. Try to avoid a  
location for the subwoofer exactly halfway along the length or width of the  
room.  
Three satellites, one subwoofer (3.1 System)  
A 3.1 system is most likely to be used for audio-visual (home theatre)  
programme. In this case the satellites should be located one either side of the  
screen, and one centrally either directly above or below the screen. The basic  
positioning guidelines for the left and right satellites are the same as for the  
2.1 system described above. The central satellite may be positioned either on  
the wall, on a furniture unit or a screen stand.  
Aego-T satellites need to be connected to an  
external power amplifier - this might be a  
conventional hi-fi stereo amplifier or a multi-  
channel home theatre amplifier/processor. In  
either case it should have the facility to provide an  
appropriate line-level subwoofer output signal.  
The location of the subwoofer is less critical but it should be placed a similar  
distance away from the listening position as the satellites. Try to avoid a  
location for the subwoofer exactly halfway along the length or width of the  
room.  
Aego-T systems comprising between two and  
seven satellites speakers may be installed with  
one subwoofer. Systems including more than  
seven satellite speakers should include multiple  
subwoofers.  
Five satellites, one subwoofer (5.1 System)  
A 5.1 system is most likely to be used for audio-visual (home theatre)  
programme. In this case, three satellites should be located in front of listening  
position, one either side of the screen and one centrally, and two “surround”  
satellites located just behind the listening position one either side of the room.  
The front central satellite should be located either directly above or below the  
screen. The surround satellites may be located well above head height. The  
basic positioning guidelines for the left and right satellites are the same as for  
the 2.1 system described earlier. The central satellite may be positioned either  
on the wall, on a furniture unit or a screen stand.  
To ensure that programme material is heard as  
intended it is important that each Aego-T element  
is located appropriately. For Aego-T systems  
comprising from two to seven satellites locate the  
speakers as described in the following paragraphs  
and refer to Diagram One over the page. Don’t  
worry if it is not practical to follow the diagram  
exactly but experiment with the options that  
are practical in order to find the one that works  
best. Once your Aego-T system is connected  
and working (see Section 6), and you begin to  
become familiar with its performance, it is likely to  
be worthwhile experimenting a little further with  
positioning.  
The location of the subwoofer is less critical but it should be placed a similar  
distance away from the listening position as the satellites. Try to avoid a  
location for the subwoofer exactly halfway along the length or width of the  
room.  
Seven satellites, one subwoofer (7.1 System)  
A 7.1 system is most likely to be used for audio-visual (home theatre)  
programme. In this case, three satellites should be located in front of listening  
position, one either side of the screen and one centrally, two “surround”  
satellites just behind the listening position one either side of the room, and a  
two further surround satellites directly behind the listening position. The front  
central satellite should be located either directly above or below the screen.  
The surround satellites may be located well above head height. The basic  
positioning guidelines for the left and right satellites are the same as for the  
2.1 system described earlier. The central satellite may be positioned either on  
the wall, on a furniture unit or a screen stand.  
Two satellites only (Stereo System)  
A stereo system is most likely to be used for  
conventional stereo audio only rather than audio-  
visual programme. In this case the satellites should  
be located near or on the wall facing the listening  
position and;  
Between 0.05 and 0.5 metres from the rear  
wall.  
The location of the subwoofer is less critical but it should be placed a similar  
distance away from the listening position as the satellites. Try to avoid a  
location for the subwoofer exactly halfway along the length or width of the  
room.  
1.0 metres from side walls and clear of corners.  
Between 2.0 and 3.5 metres apart.  
Equidistant from and angled towards the  
listening position.

3. Installation and Positioning  
Diagram One  
Note: The elongated bracket holes enable some  
adjustment for vertical alignment.  
To attach an Aego-T satellite to a wall bracket  
simply place the satellite above the bracket and  
slide it onto the mounting post.  
Note: Connecting cables to Aego-T satellites is best  
done before they are mounted on wall brackets. See  
Section 5.

Note: It is very important that wall brackets are fitted securely. If you  
are in any doubt about your ability to achieve a secure installation you  
should seek professional advice and assistance.  
Aego-T Satellite and Wall  
Bracket  
The wall bracket is held to the wall via two screws inserted through elongated  
holes in the bracket’s wall plate. No.8 (4.5mm) round-head, rather than  
countersunk-head, screws should be used. The length of screw necessary and  
type of wall fitting required will depend on the construction and condition  
of the wall. If in any doubt seek professional advice.  
Once the wall mounting locations for Aego-T satellites have been chosen use  
the wall brackets themselves as templates to mark the screw positions. Loosen  
the bracket adjustment screw using the allen key supplied and angle the  
mounting post away from the wall plate to gain easier access to the holes.  
With the screw holes drilled and appropriate wall fittings inserted, securely  
screw the brackets to the wall and return the mounting post to the vertical.

5. Connections and Amplifiers  
Satellite Connection  
Aego-T Satellite Amplifiers  
Connecting Aego-T satellites to an audio amplifier  
or audio-visual processor is fundamentally a simple  
process. If only two satellites are to be connected,  
identify the left and right speaker output terminals  
on the amplifier connection panel and connect one  
satellite to each. If three or more Aego-T satellites  
are to be used in a multi-channel home-theatre  
system with an audio-visual processor/amplifier,  
identify the appropriate output terminal for each  
channel (front left, centre, front right, etc) and  
connect a satellite to each.  
The Aego-T satellite is a relatively high sensitivity speaker that does not  
require a generously rated power amplifier for adequate volume levels to be  
achieved in an average listening room. A minimum of 25 and maximum of  
100 Watts into 8 Ohms per channel is recommended. Aego-T satellites also  
offer a relatively easy load to the amplifier and do not make unusually heavy  
demands on its power delivery.  
No overload protection systems are fitted to Aego-T satellites so it is possible  
to cause damage through over-driving. Such damage can occur whatever the  
power rating of the amplifier and is not covered by any warranty. If ever the  
sound at high volumes becomes distorted your speakers are at risk of damage.  
In such circumstances the volume must be reduced.  
Aego-T satellites are fitted with a pair of binding-  
post terminals intended to be used with stripped  
wires. Insert a stripped wire end through the cross-  
hole of each terminal and tighten the terminal  
sleeve. Take care when connecting cables not to  
touch the negative and positive terminals together.  
Make connections with all system electronics  
switched off.  
Subwoofer Connection  
The Aego-T subwoofer requires connection both to mains power and an  
appropriate subwoofer line-level output signal. The connection sockets are  
located on the back of the subwoofer. Leave the subwoofer switched-off at  
the mains until all connections are made and ensure that the subwoofer level  
control, also located on the connection panel is turned fully anti-clockwise.  
Connect the subwoofer to the audio-visual processor subwoofer output using  
an appropriate RCA Phono connection cable. Ensure that the cable is of good  
quality.  
It is important when connecting Aego-T satellites  
to ensure that each is connected with the same  
polarity. Positive speaker terminals should always  
be connected back to amplifier positive terminals,  
and negative speaker terminals connected back to  
amplifier negative terminals. Performance will be  
seriously degraded if connections are made with  
incorrect polarity.  
After checking that the mains voltage selector on the subwoofer connection  
panel is set correctly, connect the subwoofer via its IEC mains input to a mains  
wall socket. Use only the mains cable supplied with the subwoofer.  
Choice of cable type to connect Aego-T satellites  
will be influenced by the characteristics of other  
components in your hi-fi system and your dealer or  
distributor will be able to advise. Even so, there are  
some simple guidelines to consider:  
Cable runs to each speaker should be kept as  
short as possible consistent with each being  
of equal length.  
Short cable runs are especially important if  
the cable is of relatively small cross-sectional-  
area.  
If the cable is advertised as “directional” care  
should be taken to ensure that its orientation  
is as recommended.

6. Controls and System Setup  
Subwoofer Filter Frequency  
Subwoofer Controls  
The Aego-T satellite and subwoofer are designed to  
work together with a crossover frequency of 80Hz  
so the first setup parameter to adjust is to set the  
audio-visual processor’s subwoofer filter frequency  
to this value. As you adjust other parameters you  
may find that moving the filter frequency a little,  
say 10Hz either way, is beneficial. Adjust other  
aspects of the setup, particularly subwoofer phase,  
before selecting a filter frequency higher than 90Hz  
or lower than 70Hz.  
Accompanying the mains and signal input sockets on the subwoofer  
connection panel are a level control, an auto power switch and a phase  
reversal switch. Their function and use is described in the following  
paragraphs.  
Subwoofer Level  
The level control adjusts the volume of the subwoofer relative to the satellites.  
Begin with the level control set to around 50%. Detailed subwoofer level  
adjustment guidelines can be found below.  
Subwoofer Phase  
The phase switch reverses the subwoofer acoustic polarity. With the switch  
set to 0° the subwoofer output is in phase with the satellites. With the switch  
set to 180° the subwoofer output is out of phase with the satellites. Reversing  
the subwoofer phase can help optimise the sound of Aego-T satellite and  
subwoofer systems. Further subwoofer phase advice can be found below.  
Note: Despite their small size, Aego-T satellites  
can handle and reproduce full range audio, so the  
audio-visual processor should be set to treat them  
as “large” speakers.  
Sub-woofer Volume  
Subwoofer Auto Power  
Setting the subwoofer volume is important in terms  
of both overall system balance and the demands  
of different types of programme material. You  
may find that material with an emphasis on music  
works better with a lower subwoofer volume than  
movie material with an emphasis on “effects”.  
Finding a compromise between the two is a matter  
of subwoofer volume adjustment in parallel with  
adjusting its position in the room.  
The subwoofer mains power switch incorporates an automatic switch-on/  
off function. With the switch set to “Auto” the subwoofer will switch on  
automatically when an audio signal is present. It will switch off again when  
no signal has been present for around 10 minutes. With “on” selected the  
subwoofer remains switched-on permanently.  
System Setup  
Before listening to your Aego-T system make one final check of the cables and  
connections. If all appears well begin listening at a relatively low volume to  
confirm that the system is operating as expected. Only increase the volume  
if you are happy that the sound at low volume is fundamentally as expected.  
If you are unhappy, turn the system off and re-check all the cables and  
connections.  
Sub-woofer Location  
Broadly speaking, the closer a subwoofer is to the  
walls of the room (assuming they are solid brick  
walls) the more bass it will generate in the room  
(and the lower its volume need be set). Moving  
the subwoofer closer to the walls however will also  
tend to reduce the consistency subwoofer volume  
over the listening room (a corner location being  
the worst in this respect). Positions closer to the  
wall with also tend to change the character of the  
bass produced by the subwoofer - it will emphasise  
the very lowest signals more. This change in bass  
character with location is the variable that enables  
a good compromise position for the subwoofer to  
be found.  
Aego-T systems may take a little time to reach normal operating temperatures  
and to “run-in”. Your ears too will take some time to adjust to the new sound,  
so it is unwise therefore to make rapid judgements about the performance of  
the system.  
The most important aspect of Aego-T system setup is the integration of the  
satellites and subwoofer. Assuming the locations chosen for the satellites are  
satisfactory, adjusting the subwoofer’s location in the room, its volume level  
and phase, and the subwoofer filter frequency selected on the audio-visual  
processor should enable a good end result to be achieved.  
Select a few short examples of familiar programme material - both movie and  
music - to use while adjusting the setup. Listen also from a variety of different  
positions in the room. Check for balance and consistency of sound - neither  
too much nor too little bass across the range of programme material and  
listening positions. Experimentation and careful listening is the key to finding  
a good subwoofer setup.  
Sub-woofer Phase  
Switching the subwoofer phase should be left to  
last. If a good subwoofer position is proving difficult  
to find, try again with the phase reversed.
