The Sansui QRX-9001 and QRX-901 are quadraphonic receivers that represent a distinctive segment of Sansui's audio equipment lineup from the 1970s. They were designed to provide multi-channel audio playback, catering to the burgeoning quadraphonic movement. The QRX-9001 features a powerful amplifier section with a power output of approximately 100 watts per channel into 8 ohms, allowing for substantial audio output suitable for larger rooms. The receiver supports various audio formats and includes AM/FM stereo tuners with selective sensitivity, providing ample tuning capabilities. Furthermore, the QRX-9001 is equipped with a unique matrix decoding system, enabling it to deliver an immersive quad sound experience from stereo sources. With multiple audio inputs, including phono and auxiliary options, as well as speaker outputs for driving multiple speaker setups, these receivers are versatile in their application. The front panel is adorned with an array of controls, including bass, treble, and balance adjustments along with visual indicators for tuning and signal strength. The QRX-901 shares similar characteristics but may have slight variations in specifications or features that differentiate it from the QRX-9001, such as different cosmetic finishes or slight enhancements in circuitry. Overall, both models reflect the innovative spirit of the era, combining aesthetic design with functional audio capabilities.
