Marantz 4270
Stereo and Quadradial Receiver (1976-77)
The 4270 is a high quality stereo and quadradial 4-channel receiver developed by Marantz.
The unit incorporates Marantz’s exclusive Vari-matrix circuit which simulates 4-channel sound from normal 2-channel stereo programs, and is capable of reproducing 4-channel sound from any matrix encoded source.
The 4270 will also reproduce any discrete 4-channel program as well as regular stereo and monaural programs.
An optional plug-in decoder adapts the unit receiver for any specific matrix system such as Columbia’s SQ.
