Active subwoofer
Speaker for bass playback, with integrated amplifier. Very deep
frequencies can only be played back with a large-volume speak-
er. 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 compo-
nents used but is usually between 50 and 120 Hertz.
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 capa-
bility 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 Cin-
ema 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 there-
fore 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 indi-
rectly into the room (i.e. not locatable), making them different
to direct emitters (see below).
Please contact our service department if you have any questions, suggestions or if
there is anything you think we could do better.

Direct emitters
Direct emitters are conventional speakers that transport sound
to the listener in a direct line. In the home cinema, direct emit-
ters are generally used 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 sig-
nals from the DVD into as many as seven individual signals. Dolby
Digital and DTS are two different sound formats, so two differ-
ent decoders are also required. AV receivers, DVD players or cor-
responding sound cards usually have both decoders.
Level
The level controller on the subwoofer is used to adjust the vol-
ume. For perfect playback, all speaker channels – incl. the sub-
woofer – 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 recom-
mend 0°, for a position close to the listening location 180°. If the
subwoofer is in another location, the 180° setting can balance
out reduced bass. 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 subwoof-
er using a mono-cinch cable.
