The model 4300 is a high quality stereo and quadradial receiver developed by Marantz, a name famous for quality in the audio component industry.

The unit incorporates Marantz 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 4300 will also reproduce any discrete 4-channel program as well as regular stereo and monaural programs.

An optional plug-in decoder adapts the 4300 for any specific matrix system, such as Columbia's SQ.
