The New Sound ni'7lls

For many years now, audio engineers have been involved
in research which had, as an objective, the answer to a
simple question: Is contemporary two-channel stereo the
zenith of sound reproduction? Obviously, the current
array of four-channel stereo products now on the market-
place is sufficient evidence that the answer is a resounding
no. Conventional two-channel stereo has taken a re-
markable step forward-and the pleasure is all yours.
Four-channel stereo is much more than an engineering
reality, it is a genuine revolution in music for the home.
Here today. At prices well within the reach of many music
enthusiasts. And hearing is, quite simply, believing. But
what is this new sound of the 705, and why is it so different
from the two-channel sound youre so used to hearing?

If you have ever sat outdoors and listened to the sounds
around you, say the chirping of a bird, the ripple of water
in a mountain stream, the sound of a jet airplane as it
speeds above you; or if you have ever given yourself up to
the powerful fortissimo of a full orchestra and the roar of
the applause of the audience-if you have experienced all
these sounds, then returned home to your own stereo sys-
tem, you will have noticed the distinct difference between
the sounds of reality" and the sounds that emanate from
your stereo system, no matter how advanced or costly a
system it might be. The difference is not unlike watching
television immediately after youve viewed a motion
picture on a wrap-around 70millimeter screen, There is
hardly a comparison at all. And the reason is simple.
Conventional stereo sound doesnt have what the audio
experts call living presence.

Four-channel stereo makes possible the re-creation of that
living presence. In a very real sense, it places you out-
doors", again where you can hear that bird, listen to that
mountain stream, or that jet airplane. It puts you in a
near acoustically-perfect concert hall where sound rever-
berates around you, It brings sound to life. Four-Channel
sound technology is such a rapidly progressing field today
for the reason that no other form of sound reproduction
can so accurately recreate the ambiance of the concert hall
or the reality of original sound characteristics. It is the
ultimate in home music entertainment, and Pioneer is
among the very few audio companies in the world that
has researched, designed and built a total system of four-
channel sound components.
