LT 7

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.

Audio connection diagram

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:

M 7200 SW rear panel (detail view)

 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.
