Stunning 7.1 home theater performance is yours with the STR-DA4ES! Packing 110 full-bandwidth-rated watts x 7 channels of ultra-clean ES power, this receiver brings movies and music to life with breathtaking realism and subtlety. Dolby® Digital EX, DTS-ES® and Pro Logic™ II are just the beginning of the surround options. And 7-channel power lets you hook up 2 back surround speakers for a seamless 360° soundfield!

You'll love the STR-DA4ES's multibrand remote — its buttons let you control the major functions of all your A/V components, and a 4-line LCD offers easy navigation of control menus. Dual-room/dual-source A/V output lets you play 2 different video sources in separate rooms. Composite-to-S-video conversion lets you enjoy a variety of A/V sources via one simple connection to your main-room TV.

Two multichannel inputs (one 7.1, one 5.1) and a 7.1 preamp output keep you ready for future formats and system expandability. Component video switching for two sources employs 50MHz bandwidth for flawless HDTV transfer. Wide-range frequency response (out to 100kHz!) is ideal for high-resolution sources like SACD, as are the stereo and multichannel analog direct modes that bypass all DSP for especially clean sound from any analog input. Advanced power management lets you turn off digital and video circuits when they're not in use, for maximum audio purity.

The STR-DA4ES's construction and oversized "guts" reflect the ES focus on craftsmanship and sound quality: frame-and-beam chassis, a massive power supply, non-linear heat sink fins to fight resonance, OP (Optimum Pre-amplification) Processing, separate DACs for stereo and multichannel sources, an RS-232C port for software upgrades … attention to every detail, inside and out!
