INTRODUCTION
The Dynaco QD-l Quadaptor serves as a junction box between
the outputs of a conventional two channel stereo amplifier or
receiver, and four loudspeaker systems. It is a passive device,
requiring no AC power.
The Quadaptor provides the simple but essential circuitry to
recover four separate signal components from two stereo channels
utilizing the Dynaquad system. It facilitates accurate electrical
balance in the system to attain maximum separation. It also pro-
vides for listening to the front speakers alone as conventional two-
channel stereo.
The Quadaptor does not add anything to the original program,
n0r does it in any way alter the content or distortion levels of the
signals. It is not a synthesizer. A substantial portion of the
recorded material in normal two channel sources has been hidden
up to now and the Quadaptor simply makes maximum efi'ective
use of all of the information which has been recorded. A uniquely
sirnple technique of ambience recovery in Dynaquad sound reveals
this added presence or realism in your present stereo record and
tape libraries, and from stereo FM broadcasts. New source mate-
rial utilizing the Dynaquad recording technique will contain the
four directions of sound in the two conventional channels.
