AVR 347

Harman Kardon AVR 347 – High‑Definition Home Theater, Elevated

The Harman Kardon AVR 347 is a sophisticated 7.1‑channel A/V receiver engineered to deliver cinematic performance, high‑definition video handling and Harman’s signature high‑current sound. With HDMI connectivity, Faroudja DCDi video processing, advanced surround decoding and EzSet/EQ automatic calibration, the AVR 347 transforms your living room into a true home‑theater environment.

Unlike many receivers that advertise inflated wattage, Harman Kardon measures performance according to strict, real‑world standards. The AVR 347 delivers 55 watts × 7 channels (all channels driven, 20 Hz–20 kHz, <0.07% THD, 8 Ω), backed by a robust power supply and wide‑bandwidth amplifier design. This ensures effortless control, clean dynamics and a natural, detailed sound signature that brings out the best in your speakers.

With HDMI 1.1 switching, 1080p passthrough, 720p upconversion, Logic 7 processing, multiroom capability and extensive digital/analog connectivity, the AVR 347 is built for enthusiasts who want premium performance without compromise.
