Definition of Dynaquad
Dynaquad, or DY, was a matrix decoder 4-channel quadraphonic sound system developed by Dynaco in 1969.
The system originally had four speakers that were arranged in a diamond shape (centre-front, centre-left, centre-rear, centre-right).
Initially (first available in 1969 with th Dynaco SCA-80Q amplifier ), it was introduced as a derived (2:2:4) four channel "decoding" system based on the Hafler circuit, where the back channels played ambient sounds recovered from standard stereo sounds. As such it wasn't used initially used as an encoding method (a similar approach was used on the Electrovoice Stereo-4 system).
