HK 3770 is rated 4.5 out of 5 by 24.
Rated 5 out of 5 by from Best value !!! I purchased the receiver a few months ago and wanted to share my pleasure with it. I am using it to drive a pair of PSB Synchrony II bookshelf speakers with a load of 4 ohms. The receiver drives these speakers with ease and sounds terrific. I have downsized from a much larger system ( due to a move to a retirement home ) and have no regrets whatsoever. All and all, this receiver is an outright best buy .

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!

Can this receiver handle a pair of old AR-3a 4 ohm speakers and how many watts/ channel are there with a 4 ohm impedance

Asked by: pablow
Hello! The HK 3770 is capable of giving out&nbsp;120W x 2 into 8 ohms. But since your speakers are rated at 4 ohms, it means that wattage will be doubled bringing it up to 240W per channel.

This question was asked before but no real answer was given. What is the crossover frequency to the Subwoofer? Can this be set by the user to match the performance of the main speakers?

Asked by: rtrevi30
The sub output freq is not adjustable. Use a powered sub with it's own crossover will yield the results you are looking for. If your sub has selectable crossover adjustment, you can tailor the frequency at that end, not at the output of the receiver.

Forgive my ignorance. How many different zones can I operate with this device at one time. For example, can I set up the HK3770 in my home office and have speaker connectivity in 5 different rooms around the house?

Asked by: Jack Sundancer
Hi! The HK3770 is a stereo receiver and only has 2 speaker terminals for the left and right speakers. If you are looking to have like a multi room setup, we would suggest getting the AVR1710S instead because it is capable of Zone 2 and has 7.2 channels.

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?
