HK 3770 is rated 4.4 out of 5 by 23.
Rated 5 out of 5 by from Everything I was looking for. Box came smashed in from shipping company but thanks to the packaging it was undamaged, thank goodness! This thing is bomb! The sub out was a must have for my reciever. Bluetooth connects perfect with my Note 8, also a must have. Ample power, great product! Missing smart home connectivity.

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.

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 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.

I have a HK3770 and while it sounds good, the sound always seems to be weighted a bit to the right speaker. Is there any balance control built in to the receiver?

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.

There is no sound from the speakers and it says SPK NONE STEREO in the display. Have never seen that before and can't remove it or get the sound back. What should we do.
