Connecting The Loudspeakers - Teufel LT 7 Series Technical Specifications And Operating Manual

6. Connecting the loudspeakers

You can set up your LT 7 with Active Subwoofer
loudspeaker system with any standard 5.1/6.1/7.1 AV
receiver or amplifier. For the subwoofer connection,
use either the subwoofer's mono input ("Subwoofer
Input") or stereo input ("Stereo Input"). If your AV
receiver only features a mono Sub Out, you will need
a Y adapter to run a stereo cable from it. Teufel of-
fers a Y adapter as an additional accessory for this
system.

In combination with the Stereo Output, you can also
use the Stereo Input to insert the M 7200 SW THX
Select subwoofer in the audio signal chain between
preamp and power amp. This connection option is
useful if you wish to take advantage of the M 7200
SW's built-in DSP chip to fine-tune the stereo output
signal.
The cable-bound satellite speakers (M 720 FR THX
Select and M 720 C THX Select) are passive and re-
quire an amplified signal. A connection panel with
speaker terminals is provided on the back of each
speaker.
Connect the M 720 FR column speakers to the re-
spective channel outputs on your receiver/amplifier
using audio speaker cables. We recommend using ca-
bles with a minimum core diameter of 2 x 2.5 sqmm.
For longer cable distances(10 m or higher), the cable
core diameter should be 2 x 4 sqmm.
The M 7200 SW THX Select subwoofer provides a
range of connections and control on its rear panel.
These are described below:

 Subwoofer Input
The M 7200 SW THX Select subwoofer provides a
mono cinch input. Use this socket to directly con-
nect the M 7200 SW THX Select to your AV receiver's
Sub Out/Pre Out using a mono cinch cable.
 Stereo Input
The subwoofer also features a Stereo Input, which
can be used instead of the mono Subwoofer Input. If
your AV receiver only features a mono Sub Out, you
will need a Y adapter to run a stereo cable from it.
If you are using the subwoofer with a conventional
stereo system(2.1), connect this stereo input direct-
ly to the preamp outputs from the preamp/ampli-
fier/receiver.
 Stereo Output
If you are using the M 7200 SW THX Select as part
of a stereo setup featuring a separate preamplifier,
you can use this output to pass on the stereo source
signal to the power amp for the stereo speakers.
With this connection option, you can additionally
configure the subwoofer's stereo output settings
via the built-in DSP chip.
 Mains power socket
Plug the mains power cable (supplied with the sys-
tem) into this socket to connect the M 7200 SW THX
Select subwoofer to the mains.
