Up for sale is a vintage Sansui QS-500 quadraphonic synthesizer/decoder, fully tested and in solid working condition. This unit has been carefully checked to ensure all channels, inputs, and outputs are functioning properly, making it a reliable addition to any vintage audio setup. This unit has been a gem in my setup.
This model is highly desirable for its ability to both decode QS matrix quadraphonic signals and synthesize 2-channel audio into immersive 4-channel sound. Additionally, it can be used as a rear channel amplifier, making it an excellent solution for building or expanding a quadraphonic system.
