"Q. Okay, I hooked it up just like you said, turned on Zone 2, selected a 
source... but no sound! Whay am I doing wrong?
A. For all Denon receivers below the 280X/98X level, Zone 2 is ANALOG 
ONLY!!. This means your cable box hooked up with optical audio, your PS3 
hooked up with HDMI, etc. will NOT be output to Zone 2

All is not lost, however. All you need to do is, for any source which you 
would like to output to Zone 2, just "double up" your connection by running 
a second set of analog RCA cables (red/white) from the analog outs of your 
source to the corresponding input on the back of the Denon."

T.y. tau reiktų orientuotis į ne žemiau kaip 280x modelius normaliai garso 
kokybei ;)

"Q. How do I hook up a pair of Zone 2 speakers?
A. There are two ways to hook up Zone 2 speakers to your Denon AVR:
1. If you are only running 5.1 in your main zone, you can reassign your 
SURROUND BACK amplifiers to power the Zone 2 speakers. To do this, go to 
MANUAL SETUP > OPTION SETUP > AMP ASSIGN and set the assignment to "Zone 2". 
With this setup, you will hook up your two surround speakers with normal 
speaker wire and connect them to the SURR.BACK LEFT/RIGHT speaker posts on 
the back of the receiver. The receiver will power the speakers, and you will 
also be able to control the volume for Zone 2 in the receiver. "
2-u atveju reikia atskiro stereo stiprintuvo ;)
