Warranty terms
12 year warranty for speakers and 2 year war­ranty for power amplifiers and electronics (from purchase date) on materials and work time, with the exception of damage caused by incorrect use or electrical or mechanical overload. An original copy of our invoice is required as the warranty document. This warranty is exclusively valid for loudspeakers, power amplifiers and electronics that have been purchased from Teufel for pri­vate use by end customers. The warranty is not valid for loudspeakers, power amplifiers and elec­tronics that the end user has purchased from a different distributor. If the Teufel product is sold on privately, the warranty may be transferred to the purchaser, providing that the original proof of purchase is also transferred.
Returns
Teufel grants an 8 week right to exchange or re­turn the appliance for a reimbursement of the purchase sum paid. The return of individual components in a set is only possible if these components are also offered for sale separately by Lautsprecher Teufel. If one or more components are returned, any price dis­count given by Lautsprecher Teufel on all compo­nents in a set as part of the price for the set is waived. For the components returned, customers shall therefore be refunded only the difference between the set price and the purchase price of the individual components that they retain. The economic outcome for customers is as if they had bought the remaining components at the indivi­dual price from the outset.

Safety information
Important: Please read through these operating instructions
very carefully. It is essential that you take note of all of the sa­fety information and operating instructions before switching on the appliance. Please keep these operating instructions in a safe place for future reference.
Important: Please read the operating instructions. You should also follow all instructions for start-up and ongoing use.
Information on cleaning: Please do not attempt to clean the appliance using household chemicals, as this could damage the surface. Simply use a dry cloth. Disconnect the appliance from the mains before cleaning.
Caution – moisture and sunlight: Never operate the appliance in damp rooms, i.e. close to baths, showers, wash basins, drains, damp cellars or swimming pools; never use it where there is moisture. Never expose the speakers to high air humidity and avoid direct sunlight. Do not expose device to dripping or splashing water. Do not place objects filled with liquids, such as vases on the device.
Information on location: Do not use the appliance unsecured in vehicles, in unstable places, on wobbly tripods or furniture or supports that are too small. The speakers could fall and cause damage to people, including yourself. Speakers, particularly if positioned on stands or on the TV/monitor, may fall and cause damage due to their weight, even if they have been positioned securely and basically protected against falling, as a result of external influences (pulling on the cable, tripping over the cable, unintentional physical contact). This also applies to wall supports that have been attached inappropriately or incorrect­ly to walls that may not be capable of supporting their weight. Only use suitable wall brackets for mounting. Make sure that you know how much weight the walls can bear. The appliance must not be placed near sources of heat . This includes radiators and heaters, ovens and other appliances that emit heat (e.g. ampli­fiers). Sources of heat , such as fan heaters or candles, should not be placed on the speakers.
For ventilation: Slits and openings in the case have been provi­ded for ventilation. Their purpose is to guarantee reliable ope­ration and to prevent the appliance from overheating. These openings must not be blocked or covered, including by placing the appliance on a bed, sofa, carpet or other soft surface. Do not place any newspapers or table cloths, etc. on the appliance. The cooling plate of the amplifier electronics must not be covered or exposed to direct sunlight. Additional active cooling of the appliance is generally not permitted.
Electrical supply: The subwoofer must only be supplied from a power source with the correct voltage as specified on the iden­tification label. If you are unsure about the electricity supply in your home, please contact us or your electricity supplier for more information. The device must be grounded. Please only use the appropriate power cable for connecting to the power sock­et. Do not modify the power cable under any circumstances! You must comply with regulations regarding polarity and grounding. The power socket of the device will only accept a 3-pin power plug. Make sure the power switch is in the “off” position before connecting or disconnecting the device.
Information on wir ing: Please place the supply cable flat and flush to the wall and floor. Cables that are laid loosely represent a risk of tripping. This could also result in interference and cau­se the sound to be disrupted. The electricity supply cable should be laid so that it is not likely to be stepped on or squashed from the sides or above by heavy objects. Damaged cables must be replaced. Pay particular attention to the cable/plug connection, the mains socket and the cable output from the subwoofer. The
power supply cable and the cables that connect the speakers should be checked regularly for insulation faults or breaks. If a fault is discovered, the appliance and the cabling must be dis­connected from the mains immediately and the defective cable must be replaced.
During periods w ithout use: Remove the subwoofer’s power sup­ply cable from the socket for longer periods of absence or non-use.
During thunderstorms: In order to avoid damage caused by lightning strikes, the appliance should be switched off and also detached from the mains socket as soon as a thunderstorm is expected.
Risk of overload: You should not overload wall sockets, ex- tension cables or integrated appliance sockets, because this could potentially lead to short circuits and even fires. You should also avoid turning up the volume very high on the re­levant amplifier, especially if you have increased the bass using the bass control, the volume button or one of the deep bass boost switches.
Foreign bodies and liquids: Foreign bodies and liquids must not get into the appliance via its openings under any circum­stances, as they could come into cont act with parts carrying high voltages, which could then cause short circuits and fires. Therefore do not spill any liquids of any kind on the appliance.
Troubleshooting: Do not attempt to repair the appliance your­self. Contact our service department first for authorisation if you think that you can repair the fault yourself. Otherwise the appliance must be sent to our service depar tment’s address.
Transport: The appliance should be transported using a hand truck. Great care must be taken during transport. Please note that uneven surfaces, sudden stopping or inappropriate exerti­on of force may cause the hand truck and the load to fall over.
Information on spare parts: Lautsprecher Teufel will provide you with spare parts during the warranty period. Your warranty will not be invalidated if you replace the parts yourself on-site using Lautsprecher Teufel spare parts.
Unusual sounds: If any unusual sounds occur during use or the sound becomes distorted, the speaker output must be reduced immediately so that the system plays an undistorted sound.
Connecting and changing the fuse: Disconnect the mains plug. A faulty fuse should only be changed for one of the same type.
Information on volume: Loud noises can damage hearing. Sud­den high pressure may be created, particularly if a “subwoofer” in “Standby/Auto On” mode is switched on by a bass impulse at full volume. In addition to physical damage, please be aware of possible psychological consequences. Children and pets require particular care. If necessary, set the volume control of your signal source appliance to the lowest level. At high volumes, al­ways keep a certain distance from the appliance and never have your ears right next to the speaker.
Please read the following
safety information carefully.
Risk of suffocation – keep
packaging materials (e.g. the
plastic lm) out of the reach and
sight of children.
Risk of electrocution – do not
leave children unsupervised with
electrical appliances!
In case of emergency:
If any of the following occur disconnect the appliance from the mains and consult our tech­nicians:
4 If the plug or line is damaged 4 If foreign bodies or liquid
enters the appliance 4 If the appliance has been in direct contact with rain or other water 4 If the appliance does not play, even though you have followed the instructions for use 4 If the appliance has been dropped or damaged in some other way
We cannot accept any responsi­bility for incidences that occur because safety information has not been adhered to.

Introduction LT 2
Dear Lautsprecher Teufel customer,
Thank you very much for buying speakers from Lautsprecher Teufel.
You have purchased a very high-performance speaker system: Lautsprecher Teufel speaker systems are equipped with high quality compon­ents and are manufactured carefully. We recom­mend the LT 2 for providing sound in rooms up to 35 m2 in size. In this respect, only the acou­stically utilised area is taken into consideration. Neighbouring spaces such as eating areas can be ignored. Particularly high rooms over 3.50 metres should be multiplied by a factor of 1.5. The set can also be used in larger spaces where there are low requirements for continuing volume.
Before operation please read these instruc­tions carefully and store them in a safe place for future reference. If you have any further questions, please contact our engineers on Tel. +49 (30) 300 9 300 or use the email contact­form on our website www.teufel.eu. Please have your invoice number ready so that we can deal with your query as efficiently and as quickly as possible.
BEFORE contacting us with a question, please read the “Problems and solutions” section on Page 14 of these operating instructions and visit our web­site (www.teufel.eu) where you will find answers to many questions in “FAQ/Support”.
Please refer to our safety information on Page 4 of these operating instructions and only use the speakers once you have read the safety informa­tion.

Unpacking · Items delivered
Please check in advance that
the system is complete.
Please note:
Please keep the boxes for at
least the eight-week return
period, as we can ONLY repay
the full purchase price if the
products are returned in the
ORIGINAL PACKAGING in
which they were supplied!
Warning:
Inappropriate replacement of
the battery may cause explosion.
Replace only with batteries of
same type. Do not expose the
battery to excessive heat such as
sunshine or re.
If you plan to not use the device
for a longer period of time:
remove the batteries from
remote control and store them
appropriately to prevent possible
damage from leaking.
Information:
The ve passive speakers in the
set – no matter whether they
are the satellite FCRs or column
FRs – are equipped with the
same speaker chassis and are
technically identical; the column
speakers simply have an inte-
grated base that can be ignored
acoustically.
The speakers can be used in the
front, centre or rear depending
on the room requirements. We do
however recommend that they are used in pairs – for example
both column speakers TOGETHER
either for front OR rear sound.

General information on configuration
It is easy to integrate the Teufel LT 2 harmonious­ly into your living room thanks to its clear design lines and slimline shape. However, there are some configuration rules for home-cinema systems that need to be observed in order to produce the ideal sound from the Teufel speaker set.
For home-cinema systems, we recommend con­centrating on the area really used – i.e. the room (area) where the TV/screen and seats are actually located. The TV/screen should be positioned as centrally as possible to the listening location.
The recommended set-up (on the following pages), represents the best possible arrange­ment for perfect multichannel playback at home. Your available space, your partner or furniture may not always permit such ideal placement. Try to meet as many requirements as possible. Small variations are not a problem. Modern AV receivers offer numerous options for compensating elec­tronically for any compromises in the set up. Ge­nerally speaking, the following rule always applies: You can always use our recommendations to ex­periment with what works best acoustically and optically. Let your ears (and eyes) decide!
Setting up the 5.1 configuration
Centre
As the centre plays back all voice information, in­cluding the actors’ dialogues, the centre speaker satellite FCR must be as central as possible to the listening position or located above the TV/screen so that the sound and image make up a harmo­nious unit. For this the centre can be set up on the cradle supplied or fixed directly to the wall using the ap­propriate screws/rawlplugs.
Front
Using the old stereo tradition (distance to li­stener = distance between the left and right speaker), the front speakers are set up next to the TV/screen at the same distance to left and right (column speaker L 220 FR) or fixed to the wall (satellite L 220 FCR). If the column speakers have to be placed further out, you can easily turn them inwards and towards the listening location. Thanks to their magnetic screening the two front speakers can even be used near a traditional ca­thode ray TV. The following applies if the satellite FCR speakers are placed on the wall or shelves: Select a set-up height of between 40 centimetres and 1.20 me­tres (lower edge). It is important that the centre and front speakers are approximately in a line, or possibly even on a slight arc to the TV. Otherwise the homogeneity of the playback may vary with run time differences. Setting the speakers up in this way allows them to deliver their full sound potential.
Tip:
The sound from the column
speakers benets from being
near a wall.

Setting up the 5.1 configuration
We recommend placing the subwoofer in the front grey area.
Select position area A or B.
We recommend placing the rear speakers in the rear grey area.
Subwoofer
The location of a subwoofer with a recommended cut-off frequency of 110 Hz can be freely selected and does not affect the other speakers. Place­ment within a straight line between the two front satellites is ideal. But you can also try it out at any other location in the room. Thanks to its ma­gnetic screening, it can also be placed near the TV. We must, however, advise you not to use it as a “TV table” as the subwoofer’s vibration may cause the TV to “wander ” – with potentially damaging consequences to the appliance and users.
Rear
The rear speakers should be set up to the left and right either to the side or behind the liste­ning location – ideally at the same height as the front speakers, e.g. on a shelf or directly on the wall. The speakers can be fixed higher than the front speakers (up to 2-10m); but we advise you not to locate them lower.
We always recommend that the distance between the rear speakers and the listening location is over 1.00 m. But if you (have to) sit closer, please ensure that the front of the speaker is not poin­ting directly at you but rather angle the speakers more into the room. Or create a greater distance by positioning the speakers higher than 1.20m.

Setting up the 7.1 configuration
We recommend placing the subwoofer in the front grey area.
We recommend placing the rear speakers in the rear grey area.
If you add an additional pair of L 220 FCR speakers to your 5.1 complete set (refer to Page 7 of these instructions) you can also use the complete per­formance range of a 7.1 AV receiver and therefore use the LT 2 as a 7.1 home cinema system.
Front · Centre · Subwoofer · Rear (side)
The speakers are set up in the same way as for the
5.1 set. Please read the description in “Setting up the 5.1 configuration” on Pages 8 and 9 of these instructions.
Rear Centre
The ideal placement of a 7.1 system assumes that the rear effect speaker (rear side) is fixed to the
sidewall next to the listening location and the rear centre speakers are on the back wall; always at a height of 0.40–2.10 metres. The same height as the rear side speakers would be perfect . If you use the FCR satellites as the rear centre, you can fix these to the wall horizontally or vertically. If you visualise the set up graphically and link the four rear speakers with lines you will ideal­ly get a trapezoid with equal length arms. Each arm should be longer than 1.00 metre. As soon as the arms have different lengths or the four rear speakers are set at different heights, you can ba­lance this asymmetry by entering the distances of the individual speakers in the AV receiver’s speaker setup.

Connection
The LT2 in the 5.1 configuration with an active subwoofer can be connected to any normal Dol­by Digital/DTS 5.1/6.1/7.1 AV receiver. For a 7.1 AV receiver you do not use the rear centre socket(s). If you already have a modern 7.1 AV receiver you can expand your theatre LT 2 with two additional L 220 FCR satellites to make a 7.1 home cinema set. Connect the front, centre and rear speakers to a
5.1 AV receiver as per the diagram in Fig. 1.
Connect the subwoofer output (Sub Out) of your Dolby Digital/DTS-AV receiver via a mono-cinch cable with the right Line Input of the subwoofer as per the drawing in Fig. 2. The left input (Line Input L) remains unoccupied. A Y-adapter is required to use both of the subwoo­fer inputs (refer to Accessories, Page 7).

Settings · Operating elements (remote control)
Setting up the AV receiver
For your home cinema system LT2 with active sub­woofer, select the “small” or “normal” (not “large”) setting in the bass/speaker setup of the AV recei­ver for the satellites – this guarantees that the satellites can be fully loaded and the subwoofer and front speakers harmonise perfectly with each other.
The subwoofer must be set to “On” in the bass/ speaker setup on the receiver. The appropriate cut-off frequency in this set-up for the LT 2 is 110 Hz (100/120/150 Hz are also possible).
Setting up the subwoofer
When operating the system on the AV receiver, the frequency control on the subwoofer/remote con­trol must be set to “Maximum” = “140 Hz” becau­se the cut-off frequency is set by the AV receiver – its settings are dominant.
Modern AV receivers set the subwoofer phase correctly when adjusting the distance of the subwoofer from the listening location during “speaker setup” – so the phase controller on the subwoofer itself should be left in the “0°” positi­on. For older AV receivers or appliances without an option to compensate for the distance of the subwoofer, the following applies: With the phase controller, you can adjust the sub­woofer to the satellites such that the speaker membranes vibrate in the same direction in the cut-off frequency range. If the phase is set incor­rectly, the bass may be weakened or cancelled. For a subwoofer position between the front spea­kers, we recommend “0°” (grey field in the illus­tration on Page 8), for a position near the liste­ning location “180°”. If the subwoofer is in another
location, the “180°” setting can balance out the reduced bass playback. Set the phase controller appropriately to get the strongest bass playback.
The volume setting of the subwoofer may be slightly different when playing back music com­pared with home cinema sound, depending on the recording quality and mixing. Whereas a massive bass element predominates on DVDs with lar­ge quantities of special effects, for music the desired level is sometimes not reached (especially if the set has been set up for ideal DVD playback). In this case, the user’s own taste is the main de­termining factor in finding the right compromise between the two sources.
This is how you can gradually find the best volume for the subwoofer: We do not recommend selecting an automatic setting for the subwoofer using the integrated calibration computer (if the receiver has such) but rather setting the subwoofer in the bass/ speaker setup to a high value between +8 and +12 dB (around setting “55” on the subwoofer). This guarantees operation of the auto on/standby mode; then you can determine the ideal level for the subwoofer by carrying out listening tests.

Volume
This sets the subwoofer’s volume. Increase the volume using the “+” button and decrease it using the “–” button.
Frequency
Here you can align the subwoofer’s cut-off fre­quency with the satellite speakers. For operation on the AV receiver press the “140 Hz” button. The display on the front of the subwoofer then shows “14”.

Line In
You connect your mono-cinch cable (possibly with a Y-adapter) from the sub out of the AV receiver here.
Line Out
Here you can connect an extra subwoofer in or­der to generate additional bass sound or balance your room resonance.
Power Function (Auto)
When switched to “ON”, the subwoofer is perma­nently on. If you set the switch to “AUTO ON”, the subwoofer will switch on automatically when it receives a signal. If it receives no signal, it switches itself off after about 20 minutes.
Phase
Here you set the subwoofer’s phase in relation to your front and centre speakers. If the subwoofer is set up in the grey area of the drawing on Page 8, set the phase to “0°”, otherwise to “180°”.
High Level Input/Output
These sockets are used to connect the subwoo­fer to older stereo amplifiers/surround receivers that do not have a subwoofer output. These con­nections are not used for multichannel AV recei­vers with a sub out.
Power
When set to “OFF”, the subwoofer is switched off, and on when it is set to “ON”.
L 2200 SW Subwoofer front
Volume controller
You adjust the volume of the subwoofer here from “00” to “80” – the “Volume” diode to the left of the screen lights up during the process. When you release the volume control, the screen jumps back to the value of the transfer frequency, normally “11”. The “Frequency” diode lights up . By pressing the “Frequency” button, you can skip through the four different presets for the cut-off frequency: “05” - “08” - “11” - “14”.
Display and operating diodes
If the subwoofer is switched off at the power mains switch , no operating diodes light on the
screen. If the subwoofer is switched on at the main power switch , two small operating diodes light up red on the screen depending on the set­ting of the power function slide control . If the subwoofer is in standby mode = power function “AUTO ON”, the two operating diodes light on the screen. If the subwoofer is then switched on, the screen shows the programmed cut-off fre­quency. If the subwoofer switches off after about 20 minutes because it has not received a signal, the two small diodes on the screen light up again. If the subwoofer is switched to ongoing operation = Power function “ON” the screen displays the programmed cut-off frequency.
Explanation of symbols
The arrow-headed lightning symbol in an equilateral triangle indicates the presence of a dangerous uninsulated electrical voltage within the system housing and therefore a risk of electrical shock.
The exclamation mark in an equilateral triangle, as afxed to the appliance, makes the user aware of important operating and maintenance instructions.
This product complies with the European Community Council guidelines 2004/108/EC and 2006/95/EC.

Cleaning
To make sure you are able to enjoy your product from Lautsprecher Teufel for a long time, please note the following tips:
Do not expose the casing to direct sunlight. Avo­id extreme temperature differences and protect
your speakers from moisture. When cleaning the speaker, only use a slightly damp or dry cloth. Avoid using materials that contain alcohol or are abrasive. Remove dust from the membrane very carefully with a dry cloth.
The subwoofer doesn’t play
light up, reduce the subwoofer volume to “00”, remove the subwoofer cinch cable from the am­plifier, turn the volume up carefully and touch the cinch thermal resistor of the cinch cable (inside) with your finger. If you can hear buzzing or crack­ling, the defect is in the amplifier or its settings. If the subwoofer remains silent in both cases, please contact our service department.
The subwoofer buzzes
These buzzing noises may be produced by con­nected appliances or faults in the power net­work. Excessive buzzing usually has the following causes:
1.
The subwoofer is connected to a different power circuit from the rest of the equip­ment. Ensure that all linked appliances are connected to a single power circuit or plug.
2. The aerial connected to the equipment or
TV has a different ground potential to the plug. To test this, simply remove all aerial cables from the wall socket. If the inter­ference stops, you need a sheath current filter (available for around Euro 5–10 from electronics retailers). It is inserted bet­ween the aerial socket and the TV or recei­v e r.
3. A separately purchased mains filter, to
which all appliances must be connected, may be useful in eliminating the interfe­rence.
4. Occasionally, a multiple plug strip proves to
be responsible for creating buzzing noises. To test this, disconnect the plug strip and plug the subwoofer’s mains plug directly into a wall socket.
5. You can also try turning the mains plug
around and inserting it into the socket the other way up, inasmuch as your mains plug/ socket allows this.
6. In order to better localise the cause of the
buzzing, check whether the subwoofer ope­rates without buzzing on a power circuit in another room. In addition, try disconnecting the cinch connection from the subwoofer to the receiver in order to exclude the influence of connected components.
The subwoofer does not switch on automati­cally when in “Auto ON” mode.
Some AV receivers issue the bass signals via the subwoofer pre-amplifier output so quietly that the subwoofer does not start automatically, as the weak signal is not interpreted as a switch-on request. To make sure the subwoofer switches on and off correctly in auto mode, we recommend turning the level control on the subwoofer only to “55” and increasing the output level for the sub in the receiver’s speaker set-up – sometimes up to the maximum (+10 dB or +12 dB). The subwoofer should then work perfectly. If not, you can change the setting to permanently “On”.
The subwoofer reacts to the remote control of another appliance.
As there are no fundamental regulations on the distribution of frequencies, each manufacturer can work with the code of its choice. Unfortuna­tely, the fact that there may be occasional cross­overs in individual cases cannot be prevented. This is, however, not a fault in the subwoofer. If there are incompatibilities, you can try to cover the subwoofer ’s receiving diode with opaque adhesive tape. If, however, you have the freedom to choose another location and can locate the subwoofer outside the range of the receiver’s re­mote control (i.e. not right next to the receiver) this may reduce this problem, as the reception spectra may then no longer overlap.

Active subwoofer
Speaker for bass playback, with integrated amplifier. Very deep frequencies can only be played back with a large-volume spea­ker. To make sure that the front speakers can be kept as com­pact as possible, a separate subwoofer is used for bass tones. It can be located unobtrusively in the living room: for instance, behind the sofa or under a side table. The cut-off frequency between the front speakers and the subwoofer depends on the components used but is usually between 50 and 120 Her tz.
Auto On/Off function
The Auto On/Off function switches the subwoofer on as soon as a signal is detected and off again a certain time after the last signal was transferred (around 20 minutes).
Centre
Central speaker in the home cinema system. All dialogues are played back via the centre. Therefore, good voice playback capa­bility is essential for the centre.
Cinema Set
All Teufel speaker systems that are supplied with three direct front speakers and dipole effect speakers are also called a Ci­nema Set . In contrast, five direct speakers are called Concert Sets.
Concert Set
All Teufel speaker systems with five direct satellites are called Concert Sets. In contrast, Cinema Sets have three direct front speakers and a dipole rear speaker.
Dipole
Dipole speakers emit sound in two directions. They are there­fore ideal rear speakers for your home cinema because their emission characteristics imitate the speaker arrangement in a commercial cinema. Cinemas always use multiple speakers for the rear channels and their sound is distributed throughout the whole room. Dipoles have been designed to emit sound indi­rectly into the room (i.e. not locatable), which is different from direct emitters (see below).
Direct emitters
Direct emitters are conventional speakers that transport sound to the listener in a direct line. In the home cinema, direct emit­ters are used generally to play back the three front channels; in Concert Sets they are also located to the rear.
Dolby Digital/DTS Decoder
Electronic switching to divide up the digital multichannel si­gnals from the DVD into up to seven individual signals. Dolby Digital and DTS are two different sound formats, so two different decoders are also required. AV receivers, DVD players or corresponding sound cards usually have both decoders.
Frequency/cut-off frequency
This is where you stipulate the frequency used for playing back sounds from the satellites or subwoofer. If, for example, you set a cut-off frequency of 120 Hz, all frequencies above 120 Hz are emitted by the satellites, frequencies under 120 Hz are played by the subwoofer.
Level
The level controller on the subwoofer is used to adjust the vo­lume. For perfect playback, all speaker channels – incl. the sub­woofer – should be set such that the signals from the individual speakers can be heard equally loudly at the listening location.
Phase
With the phase controller, you can adjust the subwoofer to the satellites such that the speaker membranes vibrate in the same direction in the cut-off frequency range. If the phase is set in­correctly, the bass may be weakened or cancelled. If the sub­woofer is located between the front speakers we recommend 0°, for a position close to the listening location 180°. If the subwoo­fer is in another location, the “180°” setting can balance out the reduced bass playback. Set the phase controller appropriately to get the strongest bass playback.
Rear speaker
Effects and atmospheric sounds are played back via the rear
speakers (either ĕ dipoles or ĕ direct emitters). This gives a
greater spatial feel when playing back films and music.
Sub Out
Output on the receiver/amplifier to connect an active subwoo­fer using a mono-cinch cable.
5.1/7.1 pre out
Pre-amplifier output on the receiver or output on the DVD pla­yer. One analogue signal is provided for each channel via cinch connection.
6.1/7.1 technology
Surround sound procedure that, in addition to the left and right rear channel (and the relevant speakers), also uses a centrally played back rear channel. Depending on the sound format, this “rear centre” is embedded in the stereo signals for the left and right rear channel (“matrixed”) and extracted for playback (e.g. for THX® Surround EX, Dolby Digital EX) or transferred as an in­dependent signal. Instead of the dominant 5.1 technology, these are therefore 6.1 sound formats. In practice, it has proven to be beneficial for the sound to allow the rear centre to be pla­yed back by two centrally located rear speakers. AV technology equipped with the necessary amplifiers and connections is the­refore called “7.1” although it only plays back a 6.1 signal.
