Glossary
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 are 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 utilised
components 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 (ca. 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
emitting front speakers and dipole effect speakers are also
called a Cinema Set. In contrast, five direct emitting speakers
are called Concert Sets.
Concert Set
All Teufel speaker systems with five direct emitting satellites
are called Concert Sets. In contrast, Cinema Sets have three di-
rect emitting front speakers and a dipole rear speaker.
Dipole
Dipole speakers emit sound in two directions. Therefore, they
are ideal as rear speakers for home cinema because their emis-
sion characteristics reflect the speaker arrangement found in
commercial cinemas. Cinemas always use multiple speakers for
the rear channels and their sound is distributed throughout the
theatre. 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 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 the digital multi-channel signals
from the DVD into as many as seven individual signals.
Dolby Digital and DTS are two different sound formats, thus
requiring two different decoders. 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 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 at equal volume 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° and 180° for a position close to the listening location. If the
subwoofer is in another location, the 180° setting can equalise
the reduced bass playback. Set the phase controller appropri-
ately 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.
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 con-
nection.
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 technol-
ogy equipped with the necessary amplifiers and connections is
therefore called “7.1” even though it only plays back a 6.1 signal.
