Pioneer SC-LX901 review

This is an 11.2-channel model adapted for the new object-oriented formats Dolby Atmos and DTS: X. The receiver is built on Direct Energy HD amplifier modules, in conjunction with Direct Power FET output transistors, to suppress high-frequency interference. Low-jitter ESS Saber Ultra DAC chips are responsible for digital-to-analog conversion. The proprietary MCACC calibration system can accurately correct not only temporal but also phase shifts of imperfectly placed speakers and subwoofers. The device supports a rich set of network technologies. such as AirPlay and DLNA, Wi-Fi module can receive video, sound and control signals through Google Cast.
