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. Contact information can be found in Section 11. Following this introduction, the Manual is divided into sections covering Handling, Installation and Positioning, Wall Brackets, Connections and Amplifiers, Controls and System Setup, Specifications, Warranty and Contact Information. We suggest that you read at least the first six sections carefully before installing and using your Aego-T system. We would also draw your attention to the Mains Power Safety Warnings on this page. Finally, please enjoy your Aego-T system, but remember it is capable of generating high volume levels of low frequency sound, so please also be considerate of your neighbours. 1 2 3 4 5 5 5 Mains Power Safety Warnings Ensure that your Aego-T Subwoofer is set to the appropriate mains input voltage before it is connected to a mains socket. The warranty does not cover damage caused by incorrect mains voltage. The grilles are designed to protect the drive units from 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. If the mains plug is used as the disconnect device, the disconnect device shall remain readily operable. 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. Do not expose the apparatus to dripping or splashing and ensure that no objects filled with liquid such as vases are placed on the apparatus. 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. 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. 2. Handling Aego-T comprises relatively delicate precision engineered items that can be damaged by inappropriate handling. They are also heavy and in the case of the subwoofer large. Please take great care therefore when unpacking, moving and installing them. Please take care when unpacking or moving the speakers not to touch any of the drivers beneath the fabric grilles. Damage to a driver will at best degrade performance and at worst result in failure. The enclosure surfaces should also be handled sympathetically. Any cleaning should only require a soft cloth, slightly dampened if necessary. Be wary of using any polishes or solvent based cleaning agents. The packaging should be retained for future use if possible or appropriately re-cycled. AE12 Rev I 2 8/9/05, 2:34 pm 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. Aego-T satellites need to be connected to an external power amplifier - this might be a conventional hi-fi stereo amplifier or a multichannel home theatre amplifier/processor. In 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. 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. Two satellites only (Stereo System) A stereo system is most likely to be used for conventional stereo audio only rather than audiovisual 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. 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. 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. 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. 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. 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. 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. Page 1 AE12 Rev I 1 8/9/05, 2:34 pm 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. Left Front Centre Right Front Note: Connecting cables to Aego-T satellites is best done before they are mounted on wall brackets. See Section 5. Loosen the bracket adjustment screw to adjust the Subwoofer satellites vertical angle. Turn the satellite on the mounting post to adjust its lateral orientation.

Wall Brackets An adjustable wall bracket is supplied with each Aego-T satellite. To install the wall brackets proceed as described below and illustrated in Diagram Two. 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. 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.

Connections and Amplifiers Satellite Connection 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. 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 sleeve. Take care when connecting cables not to touch the negative and positive terminals together. Make connections with all system electronics switched off. 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. 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 de ...
