Solid system and happy buyer
Paired with a 5.1 set of Klipsch speakers this system really does sound great. Took some time to get it to force music to all the speakers but using the HEOS app did the trick. I've connected mine to the network with ethernet and all connecting functions are way faster than expected and even wakes/turns on remotely from music apps. Overall very pleased and would buy again.

How I Corrected Speaker Protection Flashing Light
This 5.1 system is top notch. It has all of the features that I needed and then some. Super easy install, basically plug and play. My only real comment would be once I had it installed if I turned the volume up, to where I would describe it as beginning to be loud, the unit would begin flashing a red light every .5 sec and shut down. Per the manual this was a speaker protection so I checked my speaker wiring, replaced 1 questionable wire and restripped all the others. But the same thing kept happening. I finally discovered the solution which was going into the Setup > Speakers > Manual Setup > Levels > Test Tone Start. There all of the speakers were set, by default, to 0 Db. I turned all of them up to 8Db or greater basing them on balancing out the speakers. I have not had any issues since then. I don't know for certain but believe this is similar to turning up the gain and keeps the amp from working so hard. I could be wrong on that point but I hope this helps others that are experiencing this issue. Also maybe Denon could change the default settings from the factory.

A Very Nice Receiver!
I'm very much enjoying this receiver. I have a two speaker setup: L/R. I configure the phantom center at "Low" which works very well. I also have it set up for "Music" no matter what I'm watching. The sound is very clean. The BT works very well, and am just getting into the HEOS. All-in-all, I'm very happy with my purchase.

Great purchase
Simple to setup, simple to use, and amazing to listen to! Not very experienced to be able to give feedback on the technical side of things, but as a first time buyer, I haven't had any complaints so far!

Denon lives up to its Name.
Easy setup of the unit. I am not an audiophile, but do appreciate this units capabilities. I have yet to set it up in a surround sound setup, but that will follow. Overall, very pleased with the number of inputs on this unit. I do wish that I could control my TV's power on and off with the remote. May need to do some investigation into this.

Good AVR.
Great unit, had to get the online manual, since one is not included, and a little touchy on the actions.

Perfect. Not a lot of wasted extras
Typical great Denon quality in a cleaner package. 5.1 with plenty of inputs. Latest HDMI. Not a lot of extra speakers or outputs. Perfect for standard set up

Can you just output the front speakers alone?
Mark D on Apr 24, 2022
  Thanks for your question. The SVRS960H has multiple Sound Modes (page 97 in owners manual). Select Stereo sound mode: this mode plays 2-channel stereo audio with no additional surround sound processing. Sound is output from the front left and right speakers, and subwoofer if connected. When multi-channel signals are inputted, they are mixed down to 2-channel audio and are played back with no additional surround sound processing.
