2.1 Important Information for set up
\bfter having unpacked your loudspeaker, please allow the syste\f to accli\fate to 
the te\fperature of the roo\f for approxi\fately an hour.
We reco\f\fend using high q\nuality cables to guarantee opti\fal perfor\fance.
It is i\fportant to ensure the speakers sit fir\fly on a solid surface!
We reco\f\fend that you retain the original packaging, as it is the best  way to 
guarantee safe transportation should the need to do so arise.
Please note that the loudspeakers will take so\fe break-in ti\fe to achieve 
opti\fu\f sonic perfor\fance. 
2.2  Connecting the spea\ckers
a)  Before connecting the loudspeakers to your audio co\fponents and the power 
source \fake sure that both the loudspeakers and your audio source are switched 
off and set the level controls fully counterclockwise.
\f)  Connect the loudspeakers with your audio source by using  XLR cables. The \fa\nle 
plug goes into the loudspeaker, the fe\fale plug into your audio co\fponent.
c)  Check if the specified voltage \fatches the voltage of the power supply you use. 
If this is not the case do not conne\nct the loudspeakers to a power source! Please 
contact your local dealer o\nr national distributor. 
If the voltages \fatch, use the included power cables to connect the loudspeaker 
to the \bC sockets.
d)    Switch on the \fain on/off switch on the front panel of the loudspeaker.
e)    Make sure that the line out level (volu\fe) of your stereo is either at a low level or 
all the way off. Then, switch on your audio syste\f.
f)    Turn on your source of \fusic and adju\nst the volu\fe carefully.

S7A MK2 Manual / English
3.1 
General recommendations
Please \fake sure that there are no obstacles in the way fro\f  the \fonitor to your 
ears. You should be able \nto see the speakers co\fpletely. 
The distance to the surrounding walls should be at \nleast 40 c\f to avoid early 
reflections, which will degrade the sound.
The loudspeakers should be aligned\n with the listener’s position.
Please note that vibrating parts of nearby objects can \fask \nthe sound.
Mechanical adjustments: If you plan to \fodify the speaker cabinet (e.g. dr\nilling 
holes), please cont\nact us before doing so. Usually, we will handle your warranty 
obliging.
 
3.2  Tweeter at the height o\cf ears
The Tweeter should be posit\nioned approxi\fately at the height of your ears.  If the 
speaker does not point r\night in your direction, you \fight lose sound \n
infor\fation.
In case you need to position the speaker in a significant l\nower or higher positi\non, 
the \fonitor should be angled accordingly.
3. Speaker Placement

3.3 The Stereo Triangle
If the loudspeaker is going to be used for stereo ap-
plications, the opti\fu\f listening position shoul\nd be at 
the top of an i\faginary equilateral triangle with the two 
loudspeakers should be placed\n at the other two points 
of this triangle.
The loudspeakers should be aligned\n with the listener’s 
position.
3.4  Surround Placement
Speaker positioning for \fulti-channel stereo purposes 
is ideally based on a circle with speakers placed at 0° 
(Center), 30° (Front Right), 110° (Rear Right), 250° 
(Rear Left), 330° (Front Left), with the listener being 
the circle’s center (Radius between 0.7-2.0 \f). This\n ITU 
reco\f\fended configuration \fay vary depending on the 
purpose of the control roo\f (\fusic or fil\f). \nHowever, 
it is reco\f\fended to create a sy\f\fetrical lis\ntening 
position with the front side and surround speaker 
pointing to the listener’s ear.
The distance to the surrounding walls should be at \nleast 
40 c\f to avoid early reflections, which can degrade the 
sound.

4.1 
 The front control panel
On the front you will find a new, highly sophisticated control panel that allows 
detailed fine-tuning of your loudspeakers to your particular roo\f acoustics and 
personal listening preferences. The following tips are intended to assist you at 
using the controls in the best \fanner. 
Please note that using the controls \fay have a great i\fpact on the overall sound 
characteristics  of  your  loudspeakers.  We  reco\f\fend  using  the  controls  with   
ut\fost care and only after several audio tests with fa\filiar recordings.
4.2   Input Gain
‘Input  Gain’  regulates  the  overall  input  sensitivity  of  your 
loudspeaker  within  a  range  of  -10  to  +10  dB,  and  controls  the 
volu\fe of your loudspeaker equally in all frequency ranges.
4.3   X-Curve Filter
In  large  fil\f  score  \fixing  roo\fs,  it  \fay  be  desirable  to  have 
a  representation  of  what  the  sound  is  like  in  \fovie  theatres. 
To  \feet  the  ISO  2969  Standard,  the  Dolby™  X-curve  has  to 
be  applied.  The  X-curve  engages  a  3  dB  per  octave  roll-off 
above  2  kHz.  The  S7\b  Mk2  has  a  switch  located  below  the 
input selector that activates this filter, eli\finating the need for 
external processing during fil\f s\ncore \fixing sessions.
4. Speaker Adjustment   
						

							10
4.4 Driver Gain
Whereas the ‘Input Gain’ raises or lowers the 
overall input sensitivity up \nto +/-10 dB, the 
‘Driver Gains’ work only within the corresponding 
frequency range, raising or lowering fro\f  +/-2 to 
+/-6 dB. 
4.5  High / Low Shelf EQs
The other two controls operate in a different 
\fanner. The ‘High’ and ‘L\now’ controls are shelving 
filters that progressively lower or raise frequencies 
below 150 Hz / above 6 kHz up to 6 dB (see Fig.). 
 
 
 
 
 
 
 
4.6  Bass EQ Section
There are three fully para\fetric EQs (20 Hz \nto 200 
Hz) that can be used to co\fbat standing waves 
in the control roo\f. The EQs can be\n bypassed 
individually or as a group so that their overall 
effect can be analyzed in direct co\fparison to the 
unaffected signal. 
4.7  LED Dim
\bll  LED  indicators  can  be  di\f\fed  if  necessary  by 
pressing the ‘LED Di\f’- button.
