DESC: The VSX-74TXVi was designed to do just that and more. Building on a long history of innovations in amplifier designs the VSX-74TXVi's new Direct Energy Bipolar 7-Channel powerplant delivers 140 Watts to all 7 channels with absolute detail, power, and efficiency. To harnass all of that raw power, we've gone to a whole new level of digital signal processing with a new and improved Advanced MCACC calibration system, Burr Brown 192kHZ / 24-Bit digital to analog converters, new Phase Control bass management, and new Standing Wave compensation digital technologies.
