I wanted to start setting up my 990, but the instructions state to have all components hooked up before starting proramming. I wanted to get a head start as I have a few items on order. Can I start or do I need to have everything hooked up first?
You can go ahead and start settings things up before all your equipment arrives. Just shut everything off when you start wiring in additional equipment.
Is 0dB no volume? I dont want to hook it up and blast the spakers. I am new to the quality stereo stuff and couldnt find an answer in the instructions. Why is there negative and positive dB?
There are two systems for volume control that are commonly used. One system is to go from 0 to some upper limit, in which case it should not have "dB" appended. The more traditional one defines a "unity gain" volume of 0dB that is close to the upper limit. A good way to think of it is that 0dB represents no decrease in the level of the incoming signal. A -10dB level means that the signal is attenuated - decreased - from that level. The advice that Outlaw offers in the manual (if you manually calibrate rather than using the automatic setup) is to calibrate your Model 990 so that the 0dB volume setting produces a 75dB output using the processor's internal test tones. That equates to the "reference" volume level that movies are mixed at, so playing a DVD at 0dB is going to essentially match what you would expect in a movie theater. It's pretty loud, in other words. And since TV broadcasts and CD's have a higher output level than DVD's, they will be even louder at the same volume setting.
I configured my Model 990 to power on to -35dB. The Onkyo 885 is set up the same way. That works well for watching cable TV. I turn it up when watching DVD's, Blu-rays, and some HD broadcasts.
I will be using a blu ray and xbox 360 for inputs via hdmi/dvi monster cables. I will be outputting to an Epson w6 projector via dvi/hdmi.
If you don't already have the HDMI/DVI cables, I'd suggest ordering from MonoPrice.com. They have an assortment of very economical cables available, including HDMI cables, HDMI-to-DVI cables, and HDMI-to-DVI adapters.
Will I need additional cables to process the sound from the bluray and xbox to the 990? From reading prior posts I belive I will need the following: I can run the component cable from the xbox to the 990 and run the component and hdmi from the bluray. I dont need sound to the projector. The xbox will not allow hdmi and component. it is one or the other I believe.
For the XBox, you want to run an optical digital audio cable (like the
Outlaw PDO ). For the Blu-ray player, it depends on what player you are using. If you have a player with a multichannel analog output, the notes I wrote for the
Model 990/BDP-83 setup are a good reference - you will want to use multichannel analog cables (Outlaw and
Blue Jeans Cable are both good sources for these cables). A coaxial or optical cable is also an option that you can use for DVD's, since the Model 990 has a better analog section and DAC's than most Blu-ray players (the BDP-83 being one of the few players that can stack up well against the Model 990 without costing an arm and a leg).
You will need some sort of analog video connection from the Model 990 to a display so you can see the 990's setup menu. This will presumably be your projector in this case, unless you have something small handy that can give you access to the setup menu. This can be composite video, s-video, or component video. If the Blu-ray and Xbox are your own sources, a composite video cable will be the cheapest solution.
