I often change the volume of the rear (especially) speakers secondary to differences in encoded material and if I am using one of the sound fields, as there is no feature to set the preferred volume levels for each sound field. Let you ears be your guide, not the manual. Incidentally, I do not have the DTS feature on my unit. I also do not use it's internal amps, which does IMO improve the sound.
Yamaha DSP-3090
Just got a Yamaha DSP-3090. Anyone running this and do you have any advice on best set up procedures? It has had the MSB DTS upgrade. I am used to changing the volume of the rear surround speakers because of material encoded differently on laser dics and dvds. Manual says to set and forget. I just hooked this up and am going thru a very exstensive set menu. Other 3090 ownwers, let's talk.
