Rated 5 out of 5 by from Superior Sound I’ve only had the HK3770 for a few days but I’m just so impressed with its performance, had to write a review. Absolutely 5-Star performance and sounds just amazing. Running with a pair of Pioneer towers and Polk Audio sub, has brought an entirely new life to my HiFi. Super powerful amp with virtually zero distortion. Easy set up with intuitive controls. Even though was a factory recertifed unit, looks absolutely brand new. Flawless!

Rated 5 out of 5 by from Great system! I got the system some years ago - and the bluetooth function is wonderful. Only problem I have is that my macbook pro doesen't find the HK 3770.

Rated 5 out of 5 by from AWESOME Bought this receiver a few weeks ago & installed it today. Wow, it sounds awesome & looks sweet! 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 5 out of 5 by from nice sound I bought this for the phono plug and it was worth it. Nice sound. I'm running JBL L100's & L36's out of the back & playing both together. Easier to use than the audio/video series of stereos that they sell (I have them too). I like this Harman better than any of the others that I own (have a few).

I'm attempting to plug in my CD player....regardless of what Aux plug it into, the menu displays as Coax...how do I change it from Coax to the corresponding Aux input I've plugged in to?

Asked by: Hawco458
Using the remote control for your HK3770, press the Aux button to toggle among the different Aux sources for your receiver, e.g., DVD, CD or the tuner. You can also use the source buttons on the front panel of your receiver to do this.

Does the model that is sold in the US also work in India with 220-240v ? Or there is a different model that needs to be bought only in Asia. Also what is recertified model? Any physical damages or they are as good as new ?

Asked by: Vsam
If you purchased the stereo receiver in the US, then the power will be 120V. However, the HK3700 220-240V version is available in other regions like Europe. Re certified are used products which are restored to like-new functionality and appearance. There may have minor cosmetic imperfections but it works as a brand new product.

I just bought the HK3770 and am driving a pair of Cerwin Vega speakers that sound awesome. My question is: can I use my headphones while plugged in to the jack on the front of the 3770 while the speakers perform and I play my drums?

Asked by: Bcamp
Unfortunately you can use either the speakers only or the headphones and cannot play at the same time.

Hello! We have 2 or 3 equipments working but, after 8 hours, they get off, changing to standnby mode. Is some way to change this state for never turn off? Thank you

Asked by: Nacho
Hi, It is actually a feature that saves power by turning the receiver to standby mode if there are no inputs or commands taken after 8 hours. One way to stop this from happening is to change the volume every 3-4 fours so it would restart the counter and you can continue playing your receivers. If that does not answer your question,Please submit a case request at https://www.harmankardon.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

&nbsp;I have PSB tower speakers and a big living room. Replacing my Harmon-Kardon 730 receiver (bought new by me &nbsp;in '74). Does the 3770 have enough power? Can I use a fan to cool it? Can I play music though the front USB receptacle or just charge by I-phone?

Asked by: J Steve Day
Comparing the HK730 which provides 40W per channel at 8 ohms, The HK3770 drives 120W per channel at 8 ohms. which is definitely more powerfull than the previous receiver that you had. Please make sure that the PSB tower that you have can handle 120W @8ohms before plugging it in. You can also use your fan to cool the receiver. Regarding the USB ports , you can only connect your USB Flash drive to the USB port on the front and select USB as the Input on your HK3770. Just make sure that the audio formats that you are trying to play are the following: WMA, MP3 or WAV.
