1. Equalisation
Before familiarising yourself with the other
functions of the appliance, we recommend that
you undertake a basic equalisation of the volume
of the connected speakers*. The aim of this
equalisation is to set the same volume level for
each of the channels at the listening position.
This is the only way to achieve harmonious and
balanced reproduction of the various channels.
Make sure you are in the best and most central
place possible for listening. Press the “standby”
button on the remote control and the decoder-
station 3 will be ready for use. Make sure that
all signal-emitting appliances, any DVD players
connected, are not active. Choose a value of “60”
for example as a reference master volume*.*
The aim: Set the levels of the centre, sub and
rear in relation to the output level set on the
front speaker.
Now press the “test” button. This activates a
test tone that runs through the five satellites
and the subwoofer in sequence. Now you can
increase and decrease the levels for the centre,
both rear loudspeakers and the subwoofer using
the remote control, until you can keep these
four speakers at the same volume as the two
front boxes.
Equalisation by ear requires a few attempts and
does not always provide perfect results first
time. For perfect equalisation of the loudspeak-
ers we recommend using a volume level meas-
uring device, available in the Teufel shop. This
appliance is a purchase that will last a lifetime
and allows considerably more precise equalisa-
tion than the ear. Bass levels primarily are often
set too loud - exact adjustment is only guaran-
teed using a measuring device.
Note: The volume settings of the subwoofer may
differ slightly in reproduction of music compared
with home cinema sound, depending on the qual-
ity of the recording and the mix. While a large
proportion of bass tones may often dominate
in effect-rich DVDs, the required level may be
partly unheard in the musical area (in particular
if the kit has been adjusted to optimal DVD
reproduction). Above all, personal taste is essen-
tial for the best compromise between the two
sources. You can directly adjust the subwoofer
level as required using the buttons “SW [+] and [-]”
on the remote control. Press the “test” button
again to complete the calibration process.
2. Adjusting the time delay (“delay”)***
In order for the appliance’s digital signal proces-
sor (DPS) to be able to convert Dolby and dts
signals perfectly, it must be informed of the
spatial positioning of the individual boxes to
each other. By setting the display it is possible to
balance runtime differences between the various
loudspeakers using a signal delay, so that the sig-
nals come from all loudspeakers to the listening
position at the same time. The “centre delay” and
“rear delay” settings on the decoderstation 3
remote control are used to make these settings.
The correct delay time is calculated as follows:
Centre Delay***
1. Measure the distance between the listening
point and the front boxes.
2. Measure the distance between the listening
point and the centre box.
3. Subtract the distance from the centre box
from the distance from the front boxes.
4. Multiply the result by 3.
This gives you the delay time in milliseconds.
Example
Distance to the front boxes = 3.5 metres,
distance to the centre box = 2.5 metres.
Subtraction of the distances equals
3.5 – 2.5 metres = 1.0 metre. Multiplied by 3
this results in 3ms delay time.
Rear delay of the rear speaker***
1. Measure the distance between the listening
point and the front boxes.
2. Measure the distance between the listening
point and the rear boxes.
3. Subtract the distance of the front boxes from
the distance of the rear boxes.
4. Multiply the result by 3, giving the delay time
in milliseconds.
Example
Distance to the front boxes = 3.5 metres,
distance to the rear boxes = 1.5 metres.
Subtraction of the distances equals
3.5 – 1.5 metres = 2.0 metres. Multiplied by 3
this results in 6ms time delay. As it is only
possible to set the rear delay in increments of
5ms, select the next possible value, i.e. 5ms.
Setting the surround decoder
***Information:
The delay can only be set
during reproduction of Dolby
Digital and dts.
*Only for use with a 5.1
surround set.
Equalisation is not
required for stereo
configuration – using
the balance control
is sufficient.
**Make sure that the
emitting amplifier
(e.g. Concept E Magnum)
reproduces all of the
channels at the same
volume.
