A home audio receiver from Harman/Kardon is powered by a high-current, ultra-wide bandwidth amplifier. It delivers identical power to every channel, regardless of speaker setup. Because an AVR (audio/visual receiver) for home theater use from Harman/Kardon powers all inputs equally, matching sound quality from device to device isn't an issue. Tech Specs for Harman/Kardon Receivers
Logic 7 processing allows every Harman/Kardon receiver to covert two-channel audio into five or seven channels with ease. This means that you will experience the same high-quality sound, even when switching among devices like DVD players, VCRs, and more. For example, some systems will get much quieter or have more distortion during video game use. This is not typically the case with an AV receiver from Harman/Kardon. Retail prices for Harman/Kardon receivers range from a few hundred dollars to a few thousand, depending on the quality and added features. All AVR models can accommodate HD (high definition) video sources and have HDTV-compatible video inputs. Selectable digital auto-polling provides flexibility in device compatibility as well. Even the lowest model on the Harman/Kardon totem pole, the AVR 135, offers 40 watts of power to six channels. The high-end option, the AVR 7300, offers 110 watts on seven different channels. Both feature an informative on-screen display and inputs on both the front and rear of the AVR device itself. Higher-end models feature multi-zone compatibility, so they can be used in multiple rooms at once. As well, specific channels for surround sound and a touch-screen universal remote can make it simpler to set up your home theater system.
