 What is SuperStereo?

Superstereo has been developed over many years by Dynavector to remedy the deficiencies of normal 2 speaker
stereo and conventional surround sound systems.
The object has been to produce a sound from music sources, whether live broadcasts or recorded mono or stereo
sound, which has the kind of immediacy, life and naturalness found in live music.

SuperStereo has been developed after much theoretical and practical study of how sound is propagated in enclosed
spaces. These studies have shown that conventional audio engineering has failed to recognise crucial aspects of the
propagation of sound. As a result, there is an ever increasing production of stereo and surround sound equipment
based on ever more complex digital techniques which is quite unable to get closer to the sound of live music.

Only the unique and patented Dynavector SuperStereo system can achieve this result.

It is theoretically impossible for a 2 speaker stereo system to produce the kind of life-like sound heard in a concert
hall since the recovery of the important dispersive elements of the original sound is thereby not possible;
and neither do the many multi-channel system on offer provide a solution.

Dynavector has perfected its SuperStereo processors which provide frequency related time delays to sound which
is replayed through additional satellite or sub speakers. The interaction of the sound between the front and sub
speakers produces significant group delays in the listening room. While the group delays are not identical to those of
the original or listening environment (which is impossible to achieve) , it has been established in many trials that an
approximate simulation can produce a life-like reality from broadcast or recorded music which is much closer to the
original sound.

 6 Channel SuperStereo

While the addition of 2 extra centre speakers using the Adp-2 SuperStereo processor with a conventional stereo
system will produce highly enjoyable and musical results, the use of the SSP-5 processor together with the Adp-2
and a total of 4 sub speakers to give 6 speaker SuperStereo will further significantly enhance the naturalness and
immediacy of the sound.

This manual explains how the best results may be obtained from such a 6 speaker SuperStereo set -up.

 Main Features of the SSP-5

(1) 4 different frequency delay patterns, selectable by remote control, to provide music replay with a closer match to
concert hall and recording studio venues;

(2 ) Instant switching between normal stereo and SuperStereo modes by remote control;

(3) Motorised, remotely controllable master volume control;

(4) Can accept inputs from two different sources, with a choice of high or low levels;

(5) Simple , front panel rotary controls for front/center and front/rear speakers' sound balance.

Speaker Locations

We recommend two alternative speaker locations.

You should choose the one best suited to the size and type of your listening room.

Position (A) Normal Location

Locate each speaker as shown in the drawing at (A)
Side speakers should be located between 1.5 and 2.5
meters from the front speakers and are best situated at
a height between 1.5 to 2.0 meters. The rear speakers
should be located at the rear wall and are best situated
near the ceiling. It is important to position the speakers
so that they face towards the front speakers.

Position (B) Compact Location

Locate each speaker as shown in the drawing at (B)
The side and rear speakers are located in the same po­sition ie between 1.5 and 2.5 meters from the front speak­ers. In this positioning the sound is directed towards the
front speakers and this layout is recommended for small
rooms with insufficient depth for rear placement, and
where the listener prefers not to have sound from the
rear. Again, it is important to ensure that all 4 sub-speak­ers face the front speakers

 POLARITY CHECK for speakers’ terminals

After listening for a while, try reversing the polarities of
the speaker terminals (+ or -) for the side and rear speak­ers, keeping the front speakers the same. Then choose
the polarity setting which gives the most natural and deep
bass.

You can reverse the polarity for the side speakers by
using the SUB SPEAKERS POLARITY switch on the
rear panel of the ADP-2.

z Small room (room depth is insufficient)

z Listener’s main music preference is Popular or Rock

music

z Listeners who do not wish to have the sound from
the rear.

 The best listening position is usually a little be-

hind the line joining the two side speakers.

 NOTE

1.When you use large speakers for the side and the rear the sound will tend to be boomy and lack definition. Even
when you use large speakers for the front you should use small speakers for the side and the rear.

Recommended speakers for SuperStereo

z Front speakers:use existing speakers
z Side speakers:use small speakers (5 – 10 cm driver unit)
z Rear speakers:use small speakers (10- 13cm driver unit)

 Recommeded speakers

2. Sealed box type rather than ported sub-speakers have the advantage that they are less affected by being put
closer to the room boundaries and can give better control in the bass, but they are often less sensitive.
Bass reflex speakers can also be used. Should you have any problems with the latter, you can improve the sound
by using foam or felt to plug the port.

3.When you wish to have high sound levels, it is still recommended to use a number of small speakers for the side and the
rear.

In this way, 2, 4 or more small speakers can be used for each channel. When this is done, the speakers, whether of 4ohms
or 8ohms, should be connected up according to the impedance of the speakers and the number of speakers being used.

So, for example, when 2 small speakers of 4ohms are being used, they should be connected in series
so as to present a load of 8ohms. When there are 2 small speakers of 8 ohms, they should be connected in parallel to give
a load of 4 ohms. When 4 small
speakers (per channel) are used, they should be connected in series and in parallel so as to give 4 ohms.

We recommend small sub speakers for SuperStereo since they are quite capable of

bringing out the ambience of even a large concert hall.
