I suspect it will make the next release if they are already working on it...

I have to say, I felt that my PBK and ARC results were better last time at least for my sub but now I have a big 3 seater couch right next to the sub. I tried moving it around but because it is so big it is hard to move even with furniture movers. I felt more bass before too but I am limited at the moment with placement. I tried 6 inches one way and between 6 - 12 inches the other way and approx 6 from the wall and back to about 2 inches from the wall.

Anways, here are my new ARC results.

Aside from ARC I did notice something strange and I'm not sure of cause. When I put in WotW the picture looked terrible. I thought the firmware was messing up the picture but then I noticed that my TV had changed to the Brilliant setting from a custom setting. I don't remember changing this especially since I didn't have the TV on until I put the movie on. I'm wondering if the update caused something in my TV to reset. Especially the CEC option popped up on my screen asking if I wanted to enable or disable. (this was the TV popup ot the MRX.)

Your response from 100 to 20Hz is quite flat and can't get much better so how would you get a better response? Have you set, in advanced settings, the sub to Flat? That could give you a more subsonic, tactile response, especially for a movie like WOTW.

If you have a sub that can play subsonic freq. at high dB levels. If you set it to flat with a low performance sub, you could damage it.

Thanks, so how does one know when they have a sub capable of this performance?

I'm trying to determine if this is something MRX video processing just "applies" to the entire image or if there is something legitimately wrong with the receiver.

I can report that with FW 50.12 "Through" is now working, with no on screen display (volume indicator).

There is still 42 hz "jump" in picture when using "auto" setting in video, but is not apparent with "Through" setting.

However there are still some small clicks when amp is changing audio codec, and somestimes even clicks between cd tracks on cd player and between commercials on TV.
Very irritating.

Besides also the change of video source often results in some "flickern" in the screen.

Some small observations, but I would categorise them as small bugs in FW.

The Hard Reset will not return you to the shipping firmware, if you have installed 50.12m, you will still have 50.12, however it will reset all of your configuration settings including your source setups (so it will feel like it is new, straight from the factory but with the current firmware).

When you do the reset, you should see something like "Factory Reset" appear on the MRX's display, at that point you can let go of the Tuner button.

The red standby light on the new firmware (NOTE: this firmware is still beta and not available publicly yet as of 8/1/2011) simply indicates that "CEC" is on.

The LED lights currently have the following colors:

Blue - On (Main & Zone 2 amps)
Red - Off (Main, production firmware 50.04); Off with CEC On (Main, beta firmware 50.12)
Black (no led) - Off (Zone 2, production firmware 50.04) Off with No CEC (Main & Zone 2, beta firmware 50.12)

Tigger, shouldn't the red light be "on" when CEC is set to "on"?
