Rated 2 out of 5 by from the HK 3770 runs hotter than HK 3490 i have had both HK 3770 (120watt per channel) and HK 3490 (120watt per channel) the HK 3770 runs hotter than HK 3490 at -45dB , -40dB and -35dB volume level (at same volume) ( this will make it LESS Durable ) ----------------------------------------------------------- ( HK 3770 ) more Heat = LESS Durable also the HK 3770 uses to much remote control i miss some of the source buttons on the HK 3770 (on the front) , like the HK 3490 had ---------------------------------------------------------- HK 3770 and HK 3490 sound the same on analog audio inputs , but sound Different on digital audio inputs

Rated 5 out of 5 by from HK the best bang for the buck I Just got my HK 3770. I love everything about it. This receiver provides the way music is meant to be heard. I'm charmed! I rarely give recommendations.

Rated 5 out of 5 by from Great clean sound. I've had this unit for four months now and it's fantastic! I'm running JBL ES80 floor speakers and an Onkyo 10" subwoofer. I primarily use it running my PS4/PS3 and cable, but also use it for music. The DLNA features are great on this unit as well. I'm not an extreme audiophile, but I do appreciate good quality sound and this setup definitely delivers that and much more (Harmon Low/High sound). The only few things I wish this unit had are: Bass/Treble controls on the unit (currently accessible via remote only), wireless (currently only hardwire connection available), and an easier access to accessing your music via Network (currently it's very tedious to go thru a lot of music with no search feature). All in all, I'm pleased with the unit which I use everyday.

Rated 5 out of 5 by from Class A/B amplifier? check! This beast has 40 amps of current to provide to speakers and I tested this with 6 ohm speakers it is 50 % efficient which is typically for a class A/B the previous model it was a wonder of 310 w with 77% efficiency, guess Harman is learning to do proper SMPS, good clean sound in evry in, including the coveted optical coaxial digital inputs for lossless audio, high quality performance

Can a graphic equalizer be hooked up to a hk3770?

Asked by: Denny280
Unfortunately, it cannot be done since the HK3770 does not have PRE OUTS. What you can possibly do is connect the graphic equalizer in between the source and the receiver.

I do not see any HDMI ports? can this receiver be used for home theater?

Asked by: hawkbrother
The HK3770 is a stereo receiver and can only receive audio signals, If you wish to have a home theater then I would suggest to get an AVR for a quality home theater. If this does not answer your question, Please submit a case request at https://www.harmanaudio.com/support-contact.html and the Customer Service Team will be more than happy to assist you.

I have just purchased HK3370 and being the first receiver I have ever owned I do have a couple of questions: 1. What is the purpose of network connection(i can play songs from devices via bluetooth) 2. Can i use an external HDD?

Asked by: alexr
The HK 3770's network connection allows you to stream internet radio and audio files (MP3 and WMA) from DLNA&reg;-compatible devices. Bluetooth connection is available but does not require network connection. The USB connection is used to play audio files from Apple devices and flash drives (FAT format) only. The USB input does not support external HDDs.

Can the auto shutoff be disabled? This receiver only stays on for 8 hours. I live in city and play background music most of day. At the very least it should be adjustable up to 10 hours.

Unfortunately, this is fixed and cannot be changed.
