The system reset does not affect the installed firmware. It only resets the user settings (input settings, speaker settings, and such). To reset the unit, hold down the "ENTER" and "MENU" buttons on the front panel while the unit is in standby mode.

will doing a system reset set the inputs i renamed to the default settings?

Yes, it will. It will return the 990 back to its original state (input names, speaker sizes, crossovers, and such as that).

Just as a warning, unplugging the unit may also correct the audio/video sync problem. I probably should have tried that first when I had the issue, but I went straight for the reset.

It certainly wouldn't hurt to just pull the plug first.

Thanks, Daryl. It worked for me too. I think gonk was onto it with his advice to check speaker distances. Anyway RESET cured the problem.
I had the same problem with a new Panasonic DVD player that I tried yesterday. With that experience I suspected my optical cable and switched the audio input to coax. And of course that didn't fix anything. I was ready to send the 990 back to Outlaw.
This forum is invaluable. My wife had just about had it with my whining.
Thanks to all. John

I installed the new firmware (USB) without a hiccup.
My DVD player images have never looked so good. CDs sound amazingly better using the 990 DAC. When I used the 1050, CDs sounded better using the CD player (Njoe Tjoeb) onboard DAC. I'm delighted with the new electronics.
Thanks to all.
