Hi there,
There are few things but very important you need to do to get the natural sound from your receiver.
Manual speakers set up prior to auto set up YPAO being the most important.
You need to configure the low frequencies manually since there is no subs, just like I do with my RX-A2050
and adjust the low frequencies at 31 hz for the RF7 or front speakers. (AVR is factory set up at 80 hz for subs use, and that cut your low frequencies.)
You might have to test several front speaker positions to get the best of them. They need space , so get away From rear and side walls. The rear port will do a better job.
minimum 7 feet apart from left to right, oriented as a triangle focused on your main listening position.
Indicate speaker configuration, and real distance for each one from your main listening position, small or large, and start the auto set up with the microphone;
I do use microphone adjustment at several seating locations, on top of furniture cushions as body equivalent the raise the mic to ear level to simulate realistic acoustic.
When it's done, don't move anything or re-do the auto set up. Any change of speaker of furniture placement will affect the acoustic and sound image.
Then switch program selector on remote for 2 channel stereo for Music and memorise on one SCENE button . RF7 reproduction is far better in stereo (or direct sound.)
When it's perfect, the singer will be like at the tip of your nose...it's real cool
Please use the Klipsch cables to hook up your RF7; KRSW1210 . (You would'nt climb a mountain with cheap harness...)
And use HDMI hi speed Monster cables platinium to get the most of your 4K video signal .
That seems basic but it's a good start. This is a fantastic receiver full of possibilities you can discover by reading and testing them. Have fun!
