HK's AVR 645 combines the best of old school, high-current sound from Harman/Kardon and burgeoning next-gen connectivity. In addition to seven channels of amplification and the expected Dolby and DTS surround decoding, the AVR 645 features HDMI...

Full range of connectivity options, great remote control, excellent audio and video features

On-screen interface can be tricky to navigate

Finding any faults with this unit is nearly impossible. If you can afford it, it comes very highly recommended.

Harman Kardon AVR 645

 

Not the most straightforward amp to use, but get the settings right, and the Harman Kardon AVR 645 rewards you with a rich home theatre experience.

EZSet equalisation results in excellent sound ; Plenty of power in reserve ; HDMI upconverting

Plasticky controls ; Terrible manual ; No HD video upscaling ; Not as intuitive as rivals

With the USB input, there is also a short silence during the start of each song as the digital converter recognises the format and converts it. We would have preferred an Ethernet connection instead of USB, as using HK's method still necessitates a...

Consumer review (cnet.com.au)

Harman Kardon AVR 645

 

I had a yamaha 657, upgraded to a denon 2805, did not work well, the store changed it for the hk 645, the thing is great, sounds beautiful, and lots of power, surprising 75w/ch. The video switching to hd a little annoying but nice.

great looks, beautifull sound, underrated power, heavy built, usb connection (great for music from the computer)

plastic volume knob and little door, video switching to hd signals is not smooth, but after it switches looks very good

Continued from above...

Good video and audio, when it is not crashed

Crashes every 2 to 3 hours of viewing, loses all signals, have to re-setup the receiver after doing a cold boot (what is this, a Microsoft machine?)

Harman Kardon AVR 645

 

I upgraded to this from the Harman Kardon AVR 520. It worked for several hours, then decided to cut the audio while watching my HD PVR. I went to the unit itself, and the entire receiver was frozen. Not even the soft power button worked. I switched...

Sound is great

Even though the composite inputs can now be viewed on the component monitor output, still, there is no way to see the volume/mute, etc. when viewing a component HD source. This is frustrating, because my components are in another room, so no way to...

Product Specifications

The AVR 645 not only switches two HDMI 1.1 sources; it is able to decode Dolby Digital, DTS and PCM audio streams from the HDMI inputs. Add USB audio, iPod connectivity and XM-Ready capability to the EzSet/EQ system and high-current amplifier, and the AVR 645 performs with ease. Equally impressive on the video side is format conversion so that all analog video inputs may be viewed via component outputs, and A/V Sync Delay, which reconnects the timing of sound and images. There is no better combination of sound and image anywhere.
