Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 435

K. Miller calibrated my display and I noticed an improvement in PQ with direct hook up to display.

Brian-HD said: The green screen is from the Oppo. I had the Sony 790, and the Panny without green screen connecting to the MRX. I have the 105 which was connected to the MRX without green screen.

Really? So it must be the 93, if you have the 105 hooked up and it is not doing it. What is your order of power on sequence for your VT50, 105, and MRX?

As per Oppo, Anthem should update their FW to fix smooth HDMI connection.

Check my post above yours, #13022

Display >MRX> Oppo (105) but it did not worked with any changing of tuning device first when I had the 95. Sony 790 and Panny 500 was vert smooth.

Thanks! I tried different sequences too to no avail. Thought maybe I missed something. When you had your 105 connected direct to MRX you had green screen flash? Or do the newer players (103/105) eliminate the problem?

There was not any green screens

Right now I do have HDMI 1 from Oppo 93 going straight to my Panny VT50; HDMI 2 goes to Anthem for Audio. So far so good. My panel has almost 100 hours on it and will most likely be calibrated by Jeff Meier in January.

I recently saw the measurements from the old (2009) Olive et al. blind preference test of room correction systems, and something struck me that I didn't notice before.

The major difference between an early version of ARC (ranked second-to-last) and RoomPerfect (ranked third) is the amount of "room gain." (ARC does seem to do a better job in the midrange, but marginally so.)

ARC more-or-less levels off the bass after accounting for the upper-bass swell, whereas RoomPerfect keeps adding boost.



Copying the RoomPerfect curve should be pretty easy to do with ARC an externally powered subwoofer.

Anyone tried targeting a continuously rising bass response rather than the standard room gain "step"?

I am sure that he will inform you of the same conclusion.

Hey Brian, not sure what you are saying Jeff will inform me of?

That it is better to connect directly to display compare to MRX pass through.

Agreed. Was confused on the "will" inform me. He calibrated my last display so I've already received the advice once. He'll be back in January to calibrate the VT50 and I'm sure I'll here it again

I have an Oppo 93 running through my MRX 700 and have no handshake or green screen flash issues. You need to turn off some of the Auto Detect settings in the Oppo (which assuming you know your TV's capabilities should not be an issue). Once you do that, the handshake occurs much faster and the green flash is eliminated.

I posted up a long time ago the settings that I changed, but can't remember them all now (you could do a search on this thread for Oppo and my user name and find them I'm sure). Looking at the setup menu though, you can simply set all settings that are auto to the appropriate value to match your TV and I'm sure you will be all set.

Your settings do not eliminate the handshake issue for everyone, maybe in your setup. Do you use passthrough?

Hey guys,

I've owned my MRX 300 for a little less than a year and its been great. I have noticed that when I have the bass at +2 or +4, their is distortion. I can't hear the distortion until I'm up close to the speaker, but I still don't want it to happen. I only notice it during bass heavy songs. It sounds like their being overdriven even when the volume is at low levels. It just doesn't make sense. The last thing I want to do is send it for repair. What if I bought a new amplifier for it? Any responses are appreciated.

My settings are not set to auto. I have green flashes all the time at start-up with my Oppo BDP-93 & PS3.

Good news for those of you on the fence about buying a Mrx,I just got back from my local anthem dealer and he told me all new orders for Mrx"s have all been up to date on all firmware updates inc. For the opposed and they have taken care of all the HDMI issues..he said there will be no problems with any future Mrx purchases..so I ordered one!

I meant oppo firmware updates

How do you know the problem is not your speakers? I used to have a 300, now a 700 and no matter how high I've driven either, I have never detected distortion or clipping in the least.

They actually made that exact statement? Interesting

Yes...he told me he just got a order in from anthem of 10 mrx500s and anthem assured him they have all been updated with all the firmware updates inc. For oppo blue ray players and are 100% bug free..at least that was what he was told!

Are you on the latest firmware? There was an older firmware (much older) that had this issue. Then there was an Oppo firmware that also had the issue, but Oppo released an updated firmware that fixed it. Since I have had updated firmware (now a couple of revs behind on Oppo, current on MRX) I have not had any issues with the green flashes.

When I originally posted my settings for the Oppo, I recall they seemed to be working for others as well.

I'm currently using passthrough with my Oppo, I have not tried it as Auto or 1080p60 on the MRX in a long time.

My 93 has the newest firmware, my MRX-500 is on 50.25 which I believe is the newest.

If you are having this with your PS 3, it is likely the Anthem. From my discussion with Oppo, Anthem AVR does not work well with other devices. Did you had a previous AVR?

Yes, I have had two previous AVR's and never noticed the green flash screen at start up. I have owned a Denon AVR-3808 and an Integra DTR-70.2

I recently bought an MRX300 and I was coming from a Pioneer Elite VSX-92TXH for the last 5 years. Since 2009 I had run a Monoprice High Speed HDMI 1.3a, Category 2, 22AWG 25 foot cable to my Mitsubishi projector in our theater with no problems at all. Once I switched to the MRX300 I got nothing but handshake issues(green flashes) and I couldn't use the "through" setting without it shutting down my projector after about two mins. Even setting the MRX300 to the projectors resolution of 1080p didn't work without shut downs and flashes.

As a source I was using a PS3 and Comcast DVR and both had the same problems going through the MRX300, but without the MRX300 they worked fine going directly to the projector and through my Pioneer receiver for the last few years. I ordered a Monoprice 30ft Slim Series High Speed HDM Cable w/ RedMere (which is a powered cable) and everything works in now. I can use "through" on the MRX300 and get the sources native resolution to my project or I can set the MRX300 to 1080p and let it upconvert things with no problems. I just leave it at "through".

Just thought I'd chime in and see if this info helps anyone. Here's a link to their powered RedMere cables. http://www.monoprice.com/products/subdepartment.asp?c_id=102&cp_id=10255

The green screen is the Anthem.

SO few of you seem to have a DVR.

But it's not consistent. Any time there's an ON/OFF or resolution change or Input change it "CAN" do the green screen.

And it's NOT the "Video Mute" option, mine is set to Black.

I've had four AVR's/AVPro in the last year, the Anthem is the sloppiest and inconsistent HDMI switching of the group, except maybe the Cary C12.. Sometimes a green screen, blank screen, the mess screen, occasionally a CODEC POP, you never know the combination for the same actions. Definitely not the 1/2 second black screen of a, let's say, Marantz. It works reliably, but it has the finesse of 1970's Soviet manufacturing precision.

If using a DVR you should be able to reduce the green which is an HDMI handshake by setting the DVR to output a specific resolution all the time versus letting it output the resolution each channel broadcast. By letting the DVR output whatever resolution the channel is broadcasting, an HDMI handshake is required every time you change to a channel with a different resolution from the previous one you were on.

^ that works for me. No green screen ever with PS3, LG DVD and 2 different DVRs.
