Rated 5 out of 5 by from Great features! I got this for Christmas to replace an old 70's receiver. Surprisingly good sound. Pushes my 120 watt speakers with ease. Love having a remote and the display an extra bonus.

Rated 5 out of 5 by from Great for vinyl! Using this and a turntable for a trip down memory lane with vinyl. First remote they shipped had exploded batteries in it, but they shipped a new one with one phone call.

Rated 5 out of 5 by from Works like a charm. I bought this as a replacement for my NAD and I couldn't be happier. It came packaged great and worked perfectly out of the box. Sounds great and has a sleek interface. Would definitely buy this again.

Hoe verbind ik een iPhone met het Sound System van Harman Kardon? Moet dit via een kabel of kan dit ook via Bluetooth? Ik vind hier nergens informatie over op het internet. Alvast bedankt!

Asked by: bobwinters
Hi, Wanneer een iPod, iPhone of iPad apparaat is aangesloten op het voorpaneel van de USB-poort van de stereo-ontvanger, kunt u audiobestanden afspelen via uw hi-fi audiosysteem met behulp van de ingebouwde 24-bit/192kHz DAC. Tevens kunt u de iPod, iPhone of iPad bedienen met de afstandsbediening van de stereo-ontvanger of met de regelaars op het voorpaneel, en de iPod, iPhone of iPad opladen De HK 3700 beschikt niet over Bluetooth Mocht je nog andere vragen hebben, neem dan gerust contact op met onze klantenservice, via email customer.support@harman.com

How the bass is managed when I plug a subwoofer, all the low frequencies will be managed ONLY by the subwoofer ? Or the low frequencies will be equally played by the subwoofer AND the main speaker? There is a crossover option?

Asked by: Basshead
The low frequencies will be managed by the sub only, it will not be equally played through the other speakers. There is no crossover option to use for the HK3700.
