Powerful Harman Kardon Set, with Harman Kardon satellite speakers and powerful subwoofer. The Harman Kardon is the most versatile and multi-featured A/V receivers available, incorporating a wide range of listening options. In addition to Dolby Digital and DTS decoding for digital sources, a broad choice of analog surround modes are available for use with sources such as CD, VCR, TV broadcasts and the AVR's own FM/AM tuner. Along with the latest Dolby ProLogic II decoding technology, Dolby 3 Stereo, 5 Ch Stereo and custom Hall and Theater modes, only Harman Kardon receivers offer Logic 7 to create a wider, more enveloping field environment and more defined fly-overs and pans.
