Can you get the dealer to come out and set it up for you....not only should they get it sounding right, but you will learn a lot (just avoid the person who misled you).
Agree a price before hand, and try to get a favorable rate, given that you're a customer; and leverage the fact that they misled you.
They should be able to advise on speaker positioning/levels/distances, as well as setting up the EQ, which tailors the sound to your room and explain how Dolby Volume works:
- Go to the main menu (Press "amp" then "menu") under "Input Config"
- Scroll down to "Dolby Volume" and select "Cinema Mode"
- Scroll down one more to"Dolby Leveller" and switch off.
- Scroll down again to "DV Calib Offset" and try -6dB (Nb. The less the dBs, the greater the effect)
Once this is set up, you can access it with your remote by pressing the "Effect" button, which will scroll through Off -> Music Mode -> Cinema Mode......This makes a remarkable difference to the way it sounds over sensible volumes.
Get the dealer to help him out? Oh dear I know much more than most of the sales persons i speak with. Some of them are just a waste of space.
I did own the AVR600 but returned it. Not because i did not like the sound, just because I liked the sound of my Marantz SR6003 to that of the AVR600 in 2 channel mode. This may be because am use to the sound of the Marantz. But in suround sound the AVR600 was much better. Also the AVR600 was 6times the price of the Marantz. So all in all i decided to return it.
