HK 3770 is rated 4.3 out of 5 by 27.
Rated 5 out of 5 by from Great Receiver with a Quirky Remote I have had HK amplifiers/AVRs since the 70's. As happy with the Factory Refurbished HK3770 as I was with the others. Great sound with lots of features and plenty of power at a great price. Nice compact size to fit in tighter spaces. I hope this lasts as long as my other HKs. Due to the different types of source selector buttons on the remote and the way they are allocated to the inputs, getting the different inputs programmed on my Harmony 650 remote was a little tricky and sometimes takes two button pushes to select a desired input. Maybe I will figure it out eventually. Also did not get an Owner's Manual, just a quick start guide with the receiver but I found the Owner's Manual on-line.

The only thing I consider important that need to be said is that you need to get the update from harman pardon european site version V000.17 it comes with V000.16 and it adds Balance controls in the tone control button of the remote controller It is in th download section at then end, unzip the file and you will find a pdf with all the instructions to install this very important upgrade http://eu.harmankardon.com/harman-kardon-product-support-detail-eu/hk-3770.html

Mainly purchased to use with my Dual CS 5000 Turntable, Shure M97xE Cartridge & 2 Klipsch R-24F Speakers. Crisp, clear, warm & powerful sound, pushing these speakers excellently. Super happy with this purchase & definitely recommend.

Rated 4 out of 5 by from Solid Choice After purchasing a pair of tower speakers, I needed to find a nice units to play them. After doing some research, I found that this stereo unit produces a solid amount of clean power which will get the job done. I've used it for about a week with my Fluance signature series towers, and the HK 3770 can easily power them. The original refurbished unit did have a small issue upon arrival, but tech-support was able to exchange the unit incredibly quick.

Kan ik via BT de Onyx aansluiten op mijn HK 3700en op die manier muziek afluisteren! Dit ipv boxen met snoer?

Asked by: HuibM
Hi, In principe zonder een extra Bluetooth zender aangesloten aan de HK3700 is dit niet mogelijk. Je kan wel via de hoofdtelefoon aansluiting op de HK3700 een Bluetooth zender aansluiten, en op die manier een draadloze speaker aansluiten, maar het geluid zal niet zo goed zijn, als met gewone speakers aangesloten op de speaker uitgangen. Ook kan je een vertraging hebben in het geluid, wanneer je dit via Bluetooth draadloos verstuurt naar de Onyx. Uiteindelijk blijft het een keuze die je zelf zal moeten maken, maar ik raad dit zeker niet aan. Neem voor meer informatie even contact op met onze klantenservice, dan staan we je graag te woord voor advies.

What is the cutoff frequency at the subwoofer output?

Asked by: Oscar Cardenas
There is no set cutoff frequency at the subwoofer output, since the sub output on all of our stereo receivers is full range. You cannot use an LFE input on a powered sub. You must use the standard input and use the crossover on the sub to set the cutoff frequency to your liking.
