Rated 5 out of 5 by from Great Product I am enjoying the Bluetooth feature the most, I can be out by the pool and play all of my music and adjust the vo0lume as needed from my phone. I only have one problem that maybe someone can help with? Where do you find the right IR Remote to plug into the HK3770??

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

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 Beautiful, full-featured stereo receiver I have a set of JBL tower speakers, and I previously had them connected to an Onkyo TX-8255, and they sounded great. Now that I have them connected to the 3770, I honestly think I hear a big enough difference in quality to justify the upgrade — even without the killer features; Bluetooth is definitely a nice touch for sure, and very convenient — I have my music collection playing wirelessly from my phone all the time, and so long as you stay within range, it sounds great. Five auxiliary connection ports for RCA cables as well; I have one cable with a 3.5mm end for connecting to MP3 players or whatever I like, and I’ve one more connected to my TV; three more ports left, and I’m not sure what I’ll ever use ‘em for. I can’t tell you too much about the technicalities of this receiver’s connectivity, but you can read all about that sort of thing on this website, or in the product manual. This stereo receiver packs 120 watts of power into two channels each (240 watts total), at 8 ohms, with .07% total harmonic distortion. This receiver is fantastic. If you don’t believe me, then by all means order one for yourself. Harman Kardon ships for free and charges no tax (at least in Illinois), and offers free 30-day returns and lifetime support. Go for it.

Rated 4 out of 5 by from Solid receiverr Hard to find a good stereo receiver - this a good example - Except the display should be larger and brighter
Date published: 2015-12-19
Rated 4 out of 5 by from Powerful and clean stereo receiver I have had this receiver for a couple of weeks now and it has proven to be a clean and powerful receiver. I was initially surprised at the light weight of the unit however it must utilize newer technology as the weight does not reflect the performance. Connected readily to my four year old Ipod as well as my new IPhone 5. Still exploring other aspects of connectivity as I am interested in high resolution music files. Instructions are sketchy with limited assistance to connectivity or other control or performance capabilities.

I have a pair of JBL Studio 290 speakers with a HK3770 receiver. On the back I have 8 speaker connectors, same on the speakers but bridged with gold plated metal bridge. Can I take the plates off from the speakers and connect 2x2 wires to one speaker? 

Asked by: acqualime
Great, thank you for the prompt answer. Kindly allow me one more, probably foolish question:Is there any difference in sound quality between HK3770 and let's say an AVR171S while both run in 2 channel stereo mode?

Can i use this system (HK3770) Bi-amplification or bi-amping speaker’s using the A and B exits. If is yes.   How I connect? Thank you

Asked by: fer123md
There is no benefit to wiring your HK3770 this way. While there are two sets of speaker terminals on the HK3770, there is only a single stereo power amp inside the unit. These two sets of terminals are there for convenience if you wanted to connect a second set of speakers to the receiver. In order to bi-amp you would need two amps. The HK3770 does not provide this.

I have a pair of JBL Studio 530. They are rated at 25-125 watts at 6 ohms. Is this stereo receiver an overkill for my speakers or should I go with AVR 171s? How many watts HK 3770 puts out at 6 ohms? Thanks.

Asked by: Milos
We do not have a published wattage rating at 6 ohms. However, you will have nothing to worry about with these two components, the HK3770 and STUDIO 530. They will work great together, as the wattage ratings are close enough to not be an issue.

Have Klipsch Heresy Speakers rated at 100WPC  and with it Luxman pd 121 Turntable. Need new Receiver and seek help pairing with my speakers. Would also like it to have wifi and bluetooth. I'm confused as to what receiver to use. Thanks in advance.  

Asked by: Howard
The HK3700 can put out up to 85 watts per channel, while the HK3770 can put out up to 120 watts per channel. So, the HK3700 is a better match because your speakers can handle UP TO 100 watts per channel. However, the HK3700 doesn't offer Bluetooth. So you have two options... 1. You can get an HK3700 and a BTA10 Bluetooth dongle in order to end up with all you are looking for. 2. You can get the HK3770, and just be sure not to crank the receiver to full output, as you would end up sending more wattage to the speakers than they can handle.

I have a discontinued HKTS 15 Home Theater Speaker System; is it compatible with the HK 3770 240 watt stereo receiver. Is it compatible with Android and does Harman/Kardon provide explicit set up procedures to configure the system?

Asked by: KDdogg
The HKTS15 system is a 5.1 surround sound speaker system while the HK3770 is a stereo receiver. So when you ask if it is compatible, it is a tough question to answer. Yes, the speakers will handle the power of the receiver, being that the receiver puts out 85 watts RMS per channel, and the speakers can handle up to 80 watts RMS per channel. 5 watts is not enough to really matter, so it would work fine. However, again, this is a stereo receiver, so you will not get surround sound. You can connect four of your five HKTS15 speakers and the sub to this receiver, but you will not get surround sound. If you are looking for surround sound, I would recommend that you check out the AVR1610S. It is compatible with Android in the sense that you can Bluetooth or DLNA between the phone and the HK3770.

Can I use this with a 4 ohm speaker

Asked by: Jakesong
Yes, you can connect a pair of 4 ohm speakers to this receiver. But if you ever intend to use two sets of speakers, you cannot run two sets of 4 ohm speakers at the same time. You CAN run two sets of 8 ohm speakers at the same time.

Will this (HK 3770) accept a graphic equalizer and if it does, where do I connect it?

Asked by: Eddie
The HK3770 is not able to accommodate a graphic EQ as it does not have a Tape Monitor Loop or a preamp out/main amp in section.

Only o few butons on the remote work(on, off, volume, source, mute...and a few othera. Many of the butons doesen't work like the numeric keys, up down left right, ch/tuner, Tone Control, Menu...do you know why?

Asked by: AdrianCo
This is a multi-device remote. It expects you to control your CD player, Cable Box, etc. from the HK remote. So, when you select an input (CD, Aux) on the remote, the remote switch over to control that device. If you want to control the receiver again, you must select STEREO on the remote, so that it now knows to control the receiver.
