1. Introduction
Welcome to Aego-T. Perhaps more than any
other audio-visual product, speakers are sensitive
to installation so please take a little time to read
this manual and to follow, as far as practical,
the installation guidelines it contains. Careful
installation will help ensure that your Aego-T
system performs optimally. Should you have any
questions not covered here we are happy to try
and answer them either by telephone or email.
Mains Power Safety Warnings

either case it should have the facility to provide an
appropriate line-level subwoofer output signal.
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.
The location of the subwoofer is less critical but it should be placed a similar

Five satellites, one subwoofer (5.1 System)
A 5.1 system is most likely to be used for audio-visual (home theatre)

should seek professional advice and assistance.
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.

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.
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 bindingpost terminals intended to be used with stripped
wires. Insert a stripped wire end through the crosshole of each terminal and tighten the terminal

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

seriously degraded if connections are made with
incorrect polarity.
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-sectionalarea.
•
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 Controls
Subwoofer Filter Frequency
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.
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
