Glossary
Active subwoofer
Loudspeaker with integrated amplifier for the reproduction of
bass frequencies. Very low frequencies can only be reproduced
by large-size speakers. To permit a speaker system with compact
front speakers, the bass frequencies are handled separately by
a dedicated subwoofer unit. As bass frequencies travel largely
non-directionally, the subwoofer can be placed out of sight, e.g.,
behind the couch or under a coffee table. The crossover fre-
quency between the front speakers and the subwoofer varies
from system to system, but is usually somewhere between 50
and 120 Hertz.
Auto On/Off function
The Auto On/Off function activates the subwoofer when an
audio signal is detected at the input, and switches it off again
after a set time of inactivity (approx. 20 minutes).
Centre
The central loudspeaker of the home theatre system. Surround
sound for TV/film places most of the dialogue in the centre
speaker. Because of this, excellent reproduction of speech is a
vital quality of the centre speaker.
Cinema set
“Cinema sets” are all Teufel speaker systems that consist of
three direct-radiating front speakers and dipole effects spea-
kers. “Concert sets”, in contrast, consist of five direct-radiat-
ingspeakers.
Concert set
“Concert sets” are all Teufel speaker systems consisting of five
direct-radiating speakers. “Cinema sets”, in contrast, consist of
three direct-radiating front speakers and dipole rear speakers.
Dipole
Dipole loudspeakers are designed to emulate the authentic
surround sound experience of a cinema. A cinema's surround
speaker setup features numerous tiny speakers for the side and
rear channels, which diffuse the directionality of the sound. In
contrast to direct-radiating speakers, dipole speakers have a
non-directional design, which creates a similarly diffused sur-
round sound field.
Direct-radiating speaker
All conventional loudspeaker cabinets that directly radiate
the sound at the listener are described as “direct-radiating
speakers”. In home theatre systems, direct-radiating speakers
are primarily used for the sound channels of the three front
speakers. In Teufel's Concert sets, they are also used for the
rear channels.
Dolby Digital/DTS decoder
An electronic circuit to split digital multi-channel audio signals-
from DVDs into up to seven separate analog signals.
“Dolby Digital” and “DTS” are different audio formats, so they
require different decoders. Most AV receivers, DVD players and
surround sound cards are equipped with both decoders.
Frequency / crossover frequency
The “crossover frequency” determines at which point in the fre-
quency range the bass frequencies are separated off to the sub-
woofer. For example, a crossover frequency of 120 Hz means that
all frequencies above 120 Hz are sent to the satellite speakers,
and all frequencies below 120 Hz are sent to the subwoofer.
Level
The “Level” control on the subwoofer determines the subwoof-
er's volume. In a perfect speaker setup, all the speaker channels
(including the subwoofer) are balanced in relation to the listen-
ing spot, i.e., all the speakers appear to have an equal volume.
Phase
The “Phase” control lets you adjust the subwoofer to the satel-
lite speaker so that the membranes of all the speakers vibrate in
the same direction (“phase”) when reproducing signals around
the crossover frequency. If the phase is set incorrectly, this may
cause a reduced bass response or even bass cancellations. If the
subwoofer is positioned between the front speakers, we recom-
mend a phase setting of 0°; 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 cancella-
tions 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.
Rear speaker
The rear speakers (ĕ dipole or ĕ direct-radiating) mostly re-
produce effects and atmospheric sounds. This creates a much
more spatial sound field when playing back film sound and mu-
sic.
Sub Out
Output on the receiver or amplifier to connect an active sub-
woofer using a mono RCA cable.
5.1/7.1 Pre Out
Preamp outputs on the receiver, or DVD player outputs. An ana-
log audio signal (RCA connection) is provided for each speaker
channel.
6.1 / 7.1 surround sound format
This surround sound format features one or two rear centre
speakers between the rear side speakers. The signal for the
rear centre speaker(s), which doesn't exist in a 5.1 matrix, is
generated from the stereo signals of the rear effects channels
(e.g., THX
®
Surround EX, Dolby Digital EX), or it is provided as a
discrete channel (DTS Discrete). Even though there is only one
additional channel, this can be used to drive one (6.1) or two (7.1)
rear centre speakers. While the sound format itself is “6.1” in
both cases, the speaker setup can be “6.1” or “7.1”.
No responsibility can be accepted for
the correctness of this information.

and omissions excepted.
