Marantz America announced the introduction of its Model SR8400 A/V Receiver, a leading-edge 7.1-channel home theater receiver featuring advanced Dolby Pro Logic IIx surround processing. The new Model SR8400 completes Marantz' lineup of five high-performance A/V receivers, including its flagship SR9300 and the 7.1-channel Dolby Pro Logic IIx SR7400, as well as the SR6400, SR5400 and SR4400, each offering the industry's most advanced performance and convenience features with total installation flexibility. SR8400: Same Outstanding Performance and Features of Marantz's Flagship SR9300 Marantz' new SR8400 was engineered to deliver extraordinary sound quality and installation flexibility, utilizing many of the same leading-edge technologies and features that have set the company's flagship SR9300 apart from all competitors in the high-end home theater marketplace. Like the SR9300 it features gold-plated connectors and custom components, with a heavy-duty mechanical construction featuring an all-copper chassis and double bottom plate. A Massive Toroidal Transformer provides and astoundingly clean 110watts x 7 power output for authoritative, effortless reproduction of movie soundtracks and music. In addition, the newly developed all Discrete Current Feedback (SA-ready) amplifier design enables the receiver to deliver a minimum of 70 percent of its two-channel power rating when driving five channels simultaneously-a far more robust "real world" specification than competitive models. The SR8400 is engineered for superlative sound quality, featuring 192 kHz/24-bit D/A converters on all 7 channels along with the latest Cirrus Logic CS49400 32-bit DSP processor, for maximum resolution, dynamic range and channel separation, and comprehensive bass management facilities with variable Crossover Points (source direct and pure direct).
