Active subwoofer
Speaker for bass playback, with integrated amplifier. Very deep
frequencies can only be played back with a large-volume spea-
ker. To make sure that the front speakers can be kept as com-
pact 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 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 Ci-
nema 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), 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 emit-
ters 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 si-
gnals 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 vo-
lume. 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 in-
correctly, the bass may be weakened or cancelled. If the sub-
woofer is located between the front speakers we recommend 0°,
for a position close to the listening location 180°. If the subwoo-
fer 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 subwoo-
fer using a mono-cinch cable.
5.1/7.1 pre out
Pre-amplifier output on the receiver or output on the DVD pla-
yer. 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 in-
dependent 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 pla-
yed back by two centrally located rear speakers. AV technology
equipped with the necessary amplifiers and connections is the-
refore called "7.1" although it only plays back a 6.1 signal.
