LT 7
Before you can commence using the wireless
speakers, you need to charge up their built-in
batteries by plugging them into the mains. Once
the batteries are charged, you can activate the
speakers by turning on the power switch and
pressing the “Standby On/Off ” button on the rear
panel. Plug in the transmitter unit and switch it
on via the front panel; the wireless connection
to the speakers is established automatically (also
see Chapter 7).
Step 4: Setting up the AV receiver/amplifier
In the “Speaker Setup” section of your AV receiver/
amplifier, enter the following settings:
4
Set the loudspeakers to “small” or “normal”,
not “large”.
4
Activate the subwoofer output
(Sub Out “On”).
4
Set the crossover frequency to “80 Hz”
(also see Chapter 9).
Step 5: Setting up the subwoofer
Before you have familiarised yourself with the
subwoofer's configuration options in greater de-
tail, we recommend running the subwoofer using
the default presets.
The presets are accessed via the menu display,
which is only available when the subwoofer is fully
activated: Connect the mains power cable and
turn on the power switch on the rear panel. Next,
press the “On/Standby” button to switch the sub-
woofer into active mode.
The menu can only be accessed via the display
and buttons on the subwoofer's front panel. To
open the menu, press the “Enter” button (also see
Chapter 8).

Use the “Up”, “Down”, “Enter” and “Return” buttons
to navigate through the individual menu items.
To load up the desired preset, navigate to the
“Presets” menu. Select the preset in ques-
tion and confirm your selection by pressing the
“Enter” button. The “Presets” options are de-
scribed in-depth in Chapter 10.
Step 6: Calibrating the speaker levels
To match up the levels of the individual LT 7 spea-
kers, use the sound level meter supplied with the
system. Proceed as follows:
Place the level meter at your main listening spot
and point it directly at the front centre speaker.
Start the white noise generator of your AV receiv-
er/amplifier and successively set the individual
channels to the same volume level in reference
to the sound level meter. Make sure not to alter
the position or direction of the sound level meter
during the calibration process.
Use the Teufel sound level meter as follows:
4
Remove the protective tab from the battery.
4
Set the weighting to “C” – only the “C”
setting is suitable for measuring
the entire frequency spectrum.
4
Set the response to “Slow”.
4
Set the range to “70”.
4
Start the white noise generator on your
AV unit.
4
Adjust the levels for the individual channels on
the AV unit so that the sound level meter
always displays 75 dB (i.e., between “+4”
and “+6”).
Done!
Your LT 7 system is now fully operational. We hope
you're ready for the ride – enjoy!
