2+2+2 Information for Installation of the HiFi-Equipment
Configuration for:
- Stereo sound
The two loudspeakers are at ear level, symmetrically placed at an
equal distance from the optimum listening point; ideally, the spacing
between the speakers is equal to the distance between the speakers
and your listening point.
- 5.1 Surround sound
In addition to the basic stereo sound setup, there is a centre speaker
at the front, exactly equidistant from the two stereo speakers,
and two rear speakers (behind the listening point at each side),
and a subwoofer which may be placed anywhere.
Here too, symmetrical layout and equidistance is important; it may
be desirable to turn the rear speakers slightly toward the side
wall or the ceiling. After that, all speakers must be carefully
balanced to the same volume level following the instructions for
use of your 5.1 sound amplifier.
The subwoofer should on no account dominate the sound reproduction;
it is only correctly balanced when it can no longer be picked out
or located acoustically.
- 2+2+2 Multichannel sound
The 2+2+2 multichannel process is a recording and reproduction system
developed by MDG, compatible with stereo and surround sound.
Whereas stereo and surround sound can only provide two-dimensional
sound reproduction, the 2+2+2 multichannel process not only allows
three-dimensional sound reproduction, but provides "sweet spots"
all over the listening area.
For 2+2+2 multichannel sound, please utilize your existing stereo
speakers (in front right and left) and rear speakers (behind to
the right and left). Then mount an additional speaker pair directly
above the two front stereo speakers. The distance between each of
the upper speakers and the stereo speaker below it should be half
that between the two front stereo speakers. (It is a good idea to
position the upper speakers against the side walls.)
Example: If the two front stereo speakers are 2 metres apart, the
speakers positioned over the front stereo speakers must be about
1 metre away from them.
For three-dimensional sound, feed the signal of the centre speaker
to the upper left speaker and the subwoofer signal to the upper
right channel.
