7 Technical 5.1 speaker Specifications placement and Operating Manual General notes on speaker placement Thanks to its unobtrusive aesthetics and sleek design, the Teufel LT 3 speaker system will easily blend into your living room. In order to achieve the best possible audio quality from your Teufel system, however, there are a few speaker placement rules to consider. These apply particularly to home theatre applications. As a general guideline, any home theatre system should be concentrated around the viewing area, i.e., that part of the room that contains the TV/ screen and the main seating areas. If at all possible, the TV/screen should be placed centrally in relation to the viewing/listening spots. Our speaker placement suggestions, shown over the next pages, are designed for the best possible multi-channel sound reproduction in your home. In the reality of your living room, of course, there may be other factors working against the suggested placements. While our recommendations represent the audiophile's optimum layout, minor variations in placement will generally not significantly affect the sound imaging. Modern AV receivers also offer many options to electronically compensate for compromises in speaker placement. Always remember: Our recommendations are only to be considered a starting point. Ultimately, you will know best what works in your room, both visually and sonically. Trust your eyes and your ears! Centre Since the centre speaker is responsible for all spoken sound including film dialogue, place the FCR centre speaker at a central location relative to the main listening area to unite sound and image. A good location is often directly above or below your TV or screen. You can also fasten the speaker directly to the wall using the mounting brackets on the rear (make sure to use suitable screws/wall plugs). Front The front speakers should be positioned similarly to conventional stereo speakers where they form an equilateral triangle relative to the main listening position. In a home theatre setup, the TV/screen should be positioned in the centre between the left and right front speakers (tower speakers L 330 FR). If you need to position the column speakers further away, make sure to orient them towards the main listening spot. Since they are magnetically shielded, you can even place the two front speakers in close proximity to a conventional CRT TV. Make sure that the centre speaker and the two front speakers are positioned in a straight line, or on a slight arc with the TV/screen. If the distance between the listening position and the speakers varies significantly, the spatial imaging will suffer. Make sure to align your speakers properly to exploit their full potential. Front SW Centre Front Hint: The column speakers sound best when they are positioned close to a wall. LT 3 7

8 Technical 5.1 speaker Specifications placement and Operating Manual Subwoofer At the recommended crossover frequency of 110 Hz, the subwoofer can be positioned in the room very flexibly without affecting the output from the other loudspeakers. The ideal position is somewhere along the axis between the two front speakers, but you should feel free to experiment with placing it anywhere you like. Since the subwoofer is magnetically shielded, you can even place it near a CRT TV. However, you should never use it as a TV table since the bass vibrations may gradually move the TV until it slips off, which could severely damage both units and possibly cause injury. Rear Position the left and right rear speakers either to the side of or behind the main listening spot. The rear speakers should always be at least 1 m away from the listener. If they are any closer to the listening spot, make sure that the front of the speakers is not directly pointed at the listener but towards the centre of the room. We recommend placing the subwoofer in the grey front area. Front SW Centre Front The best default positions are indicated by A and B.

9 Technical Connecting Specifications and Operating Manual You can connect the LT 3 system to any modern Dolby Digital/DTS 5.1/6.1/7.1 AV receiver. If you own a 7.1 AV receiver, simply ignore the Rear Centre Out(s). If your receiver is 5.1, connect the front, centre and rear speakers as shown in Fig. 1. Front, centre and rear speakers AV receiver Speaker output Teufel connection panel Connect the subwoofer output (Sub Out) of your Dolby Digital/DTS AV receiver to the right Line Input of the subwoofer using a mono RCA cable as shown in Fig. 2. In this setup, the left input (Line Input L) is not connected. If you want to feed the Sub Out signal to both of the subwoofer's inputs for an additional bass boost, use a Y adapter (see Accessories, p. 6).

10 Technical Settings Specifications Controls (remote and Operating control) Manual Setting up the AV receiver To take full advantage of your LT 3 Home Theatre System with Active Subwoofer, set the Speaker Setup section of your AV receiver to small or normal (not large ) for the satellite speakers. This ensures that the speakers receive the right amount of signal, and that the subwoofer and front speakers have matching volumes. Also in the receiver's Speaker Setup section (Bass Management and/or Speaker Management), make sure the subwoofer is set to On. For the LT 3 system, set the crossover frequency to 110 Hz (if this is not available, the next best choices are 100/120/140/150 Hz). Setting up the subwoofer If your system uses an AV receiver, set the subwoofer frequency control to Maximum = 140 Hz since the AV receiver is chiefly responsible for determining the crossover frequency. Modern AV receivers determine the phase of the subwoofer automatically. Here, a Speaker Setup utility analyses the distance between the different speakers and the listening spot. For this to work correctly, the phase switch of the subwoofer must be set to 0. If your system uses an oldermodel AV receiver or another type of amplifier without a setting for the subwoofer distance: The Phase control allows you to adjust the subwoofer to the satellite speaker so that all speaker membranes vibrate in the same direction ( phase ) when reproducing signals around the crossover frequency. If the phase is not set correctly, this may cause a reduced bass response or even bass cancellations. If the subwoofer is positioned between the front speakers, we recommend a phase setting of 0 (grey area in the diagram on page 8); if the subwoofer is positioned closer to the listening spot, a phase of 180 may be more appropriate. Similarly, the 180 setting may help to eliminate bass cancellations if you position the subwoofer in other areas of the room. Always set the phase control to the position where the bass response is best. The output setting of the subwoofer may vary depending on usage, e.g., home theatre sound system or music playback. Whereas an action-packed DVD typically contains massive amounts of subbass, many pure music sources do not. This will be especially noticeable if you calibrate your system for optimum DVD playback. To find the best compromise between different sound sources, use your own subjective judgement. Our recommendation is to determine the best subwoofer volume gradually over time. As a rule, we do not recommend configuring the subwoofer volume automatically via your AV receiver's integrated room analysis computer (advanced receivers only). Instead, set the subwoofer to a high level between +8 and +12 db (approx. 55 on subwoofer) in the bass management/ speaker management section ( Speaker Setup ). This will ensure that Auto On/Standby mode functions correctly and allow you to determine the best subwoofer level through listening tests. Subwoofer remote control Volume This controls the volume of the subwoofer. Press the + button to increase the volume or press the button to reduce the volume. Frequency This controls the crossover frequency between the subwoofer and the satellite speakers. If you are using this with an AV receiver, set this button to 140 Hz. The display at the front of the subwoofer will show the following:»14«10 LT 3

11 Technical Subwoofer Specifications controls and Operating Manual L 3300 SW subwoofer front side Volume control Use this to set the volume of the subwoofer in the range between 00 and 80. While doing this, the Volume LED to the left of the display lights up. After you release the volume control, this display will return to the crossover frequency, which is normally 14. The Frequency LED will light up. Tap the Frequency key to skip through four different presets for the crossover frequency:» «. Display and mode LEDs If the subwoofer is turned off using the mains power switch, none of the mode LEDs will be lit. After turning on the subwoofer using the mains power switch, two small LEDs in the screen will light up red depending on the position of the power function slider. If the subwoofer is operating in standby mode = power function AUTO ON, the two mode LEDs in the display will be lit. As soon as the subwoofer is triggered into activity, the screen will display the crossover frequency that has been set. When the subwoofer switches itself off after approx. 20 minutes of inactivity, the two LEDs in the display will light up again. If the subwoofer is set to always be on = power function ON, the set crossover frequency will appear in the display. Symbols The lightning symbol with arrowhead inside an equilateral triangle informs the user about the danger of non-isolated electrical voltage within the enclosure with the inherent risk of electrical shock. L 3300 SW subwoofer rear side Line In Connect the AV receiver's Sub Out to the subwoofer's Line input using a mono RCA cable (optionally with a Y adapter). Line Out Here, you can connect a second subwoofer for additional sub-bass or to compensate for resonant frequencies in the room. Power Function (Auto) When set to On, the subwoofer is permanently active. At the AUTO ON position, the subwoofer will switch on automatically whenever it receives an audio signal. Here, the subwoofer will automatically return to standby mode after 20 minutes of inactivity. Phase This switch determines the phase relationship between the subwoofer and the front/centre speakers. If the subwoofer is positioned in the room as indicated on page 8 (grey area of drawing), set the phase to 0. With other setups, the 180 setting may produce better results. High Level Input /Output Use these speaker sockets to connect the subwoofer to a conventional stereo amplifier or a surround receiver without a dedicated subwoofer output. Do not connect anything here if you are using a multichannel AV receiver with a Sub Out. Power Set this to ON to switch on the subwoofer or OFF to deactivate it. The exclamation mark within an equilateral triangle, as can be seen on the back of the unit, indicates that there are important operating and maintenance instructions for the user to read. This product complies with the following EU directives: 89/336/EEC and 73/23/EEC. The waste bin symbol printed on the type plates and amplifier labels of our products indicates that Lautsprecher Teufel will ensure the proper disposal of its speakers and subwoofers in accordance with Germany's Electrical and Electronic Equipment Act.

12 Technical Problems Specifications and solutions and Cleaning Operating Manual The subwoofer is not responding If no power LEDs light up in the display, please replace the fuse. Make sure that the replacement fuse has the same rating as the defective fuse. If the power LEDs are on, reduce the subwoofer volume to 00, unplug the subwoofer RCA cable from the amp, carefully turn up the volume and touch the tip (inner conductor) of the RCA with your finger. If this produces a hum or crackle, the fault is with the amplifier or the amplifier settings. If the subwoofer remains completely silent, please contact our support team. The subwoofer hums Hum may be caused by any audio device connected as well as by problems with the mains power. In most cases, excessive hum is caused by one of the following: 1. The subwoofer is connected to a different mains circuit than the other components. Make sure that all of the connected equipment is powered from the same mains circuit, i.e., the same mains socket. 2. The antenna connected to the audio system or TV has a different earth potential than the antenna socket. To test this, simply disconnect all the antenna cables from the wall socket. If this makes the hum disappear, you will require a ferrite bead (available at most electronics stores). Simply insert the ferrite bead between the antenna socket and the TV/ receiver. 3. A line filter (to be purchased separately) can also be useful for hum removal. Note that you will need to connect all of your electrical equipment to the line filter. 4. Sometimes, a power strip can be responsible for causing hum. Try removing your powerstrip and plug the mains cable of the subwoofer directly into the mains socket. 5. You can also try rotating the mains cable by 18 0, and plugging it back into the mains socket. 6. If you have trouble locating the source of the hum, check whether the subwoofer is less noisy when you plug it into the mains socket in another room. Also try disconnecting the subwoofer RCA cable from the receiver to see whether the hum is caused by one of the other pieces of equipment. When in Auto ON mode, the subwoofer does not activate automatically Some AV receivers default to a very quiet bass output on the Pre Out/Sub Out. As a result, the weak signal does not cross the detection threshold of the subwoofer and it does not begin to play. To ensure that the subwoofer is correctly triggered in Auto ON mode, set the level on the subwoofer quite low (e.g., 55 ) and increase the receiver subwoofer output level in the Speaker Setup section. If necessary, set it to the maximum value (+10 db or +12 db). This should resolve any issues with the automatic signal detection. If this still does not solve the problem, set the subwoofer switch to ON so that it is always on. The subwoofer reacts to the remote controller from a different device Since there are no rules governing how frequencies are shared, each manufacturer is free to choose their own codes. Unfortunately, this also means that certain equipment may use overlapping frequency ranges. If this happens, this does not indicate a fault in the subwoofer. If you experience such incompatibilities with your equipment, try covering the receiver LED of the subwoofer with a light-tight piece of adhesive tape. However, if you have enough space in your listening room to move the subwoofer far enough away from the receiver, you may be able to solve this problem and prevent the remote controls from affecting the other equipment. Cleaning Please take note of the following guidelines to protect your Teufel speakers: Avoid placing the speaker cabinets in direct sunlight. Avoid extreme temperature fluctuations and protect your speakers against humidity. When cleaning the speaker cabinets, only use dry or moist cloths. Never use abrasive or alcoholbased cleaning products. If you need to clean a speaker membrane, do this very carefully using a dry cloth. 12 LT 3
