Hi Nick,

I have an antec cooler above my mrx that is connected at the back of receiver outlet, when cec is on and the unit is off the fan does not turn off. Is there a way to fix that when cec is on and unit is off the outlet at the back of the receiver does not turn on. I know there is no need to put a cooler above the receiver, i just want my receiver always warm lol smile.gif

Thanks

So far I have only connected L/R speakers to the Anthem, but I hear a popping noise out of the right front speaker in all of the same scenarios you mentioned (changing between songs, mute, loss of signal ect). I was wondering if you ever got a fix to this? I believe the MRX 700 is running the newest firmware already but I'll double check. I haven't run ARC yet because I was waiting for my new speakers to go through their first 100 hrs or so to reach peak performance before running ARC. Room Correction shouldn't have anything to do with a popping sound coming out of a speaker anyway. Also, I have already tested this on all inputs (HDMI and optical), and with both a PS3 and a satellite TV receiver, and connecting to my old speakers in addition to the GoldenEars. None of these changes made the popping sound go away. I am concerned that the popping sound could damage my new speaker, so for now while I do further testing I have the Anthem connecting to my old speakers.
Hoping to hear what if anything you were able to do to fix this issue. Also, because others say they don't have issues, I wonder if this is in combination with certain sources (my dealer suspects my PS3 is to blame, but my sat receiver also causes the same issue), or if just a certain percentage of Anthem MRX receivers have a defect. I have contacted Anthem support and am waiting to hear back from them.
On another note, I also experience a static/distortion issue when using HDMI or USB, and the issue is improved somewhat by lowering the channel gain level to the lowest possible -12db. However, when listening to the very same sources using optical, the sound is perfectly clear (except for the popping sound between songs).
Thanks,

As I believe Nick has already stated, please check your firmware and report what you have... If if is the current v50.25, than please contact Anthem Support ASAP (or update them with the firmware confirmation).

Ok so I havent seen anybody else with my problem here...

Ive just bought a new MRX 700. Connected to it on HDMI-out I have my projector and on one of the in's I have my htpc, from which I listen to music and watch movies.
That's the premise and here is when things start to behave strange. If I have my projector on and listen to music everything is fine, then after a while the projector goes into a standby mode and with that the music stops! Why? Also if I just power on the htpc and not the projector and then start some music nothing happens but if I start a film first with a DTS-track e.g. it like "wakes the receiver up" and then I can close the film and play music. But then again after like 10-15 minutes the reciever just drops the signal and I have to "wake it up" with a film again and then continue listening to music.

What kind of behavior is this? I have looked through the settings but cant seem to find anything that could correlate to this problem.

So, set the sub up to reference green dot, ran arc and its set all my speakers to +8 or 9 apart from the sub which is at -8?

Would this indicate reference is too much in my room and to turn the sub down?

What you are experiencing is not an unusual situation. The audio stops because your htpc loses the EDID when your display unit goes into standby or sleep mode. You could probably solve this issue by using a Gefen HDMI detective.

If you have a video card with dvi and hdmi out and you're running Win7, you could connect the display to the dvi out and set that as Display 1 as the projector and Display 2 as your mrx. You can then extend the desktop from Display 1 to Display 2 and turn off your display while continuing to play the audio portion.

You need to turn your sub way down. Not sure what you mean by reference, probably in one of your prior posts but I don't remember.

I see. Thanks for your input. I guess the problem is mainly in the display then. Ill have to look in to that.

The problem really lies with the htpc because it is the htpc that is losing the EDID information. This happens with many displays.

What is you video card? There have been people that have been able to solve this issue using a software patch for ATI/AMD cards.

Yes ARC would have balanced it to your other speakers and it will get balanced again when you turn the sub down and then all the trim levels will be closer to zero.

As for the speakers... I assume the screen is mostly acoustically transparent... so why is the center not at the same height as the Front L/R? As for the Centers location, I suspect your proximity to the floor maybe contributing to the dip we are seeing, as it is only a two way speaker, I don't think the dip is due to a failing mid range speaker. If you can place it up higher that may help. Of note, if I'm interpreting the speakers used in the Klipsch THX Ultra 2 set, the Front L/R speakers are the same as your center, so one would expect them to all have similar responses... this suggests it is the speakers location that is causing the dip we see.
For the subs, a few things to consider here. First question, are you using the recommended 'KA-1000-THX Amplifier'? It appears there are no controls on the subs cabinets themselves, however the amp has numerous filters we need to consider. Can you tell us how the controls on your amp are configured? For better explanation, please see the attached description of your amps controls.

I think if your subs are tight in the corners, you may want to also try sliding them closer to the center so they are at least 2 feet away from the side walls. Let us know how the controls on the amp are set and we will see if we can recommend some changes.

Hey Tigger,

Hereby my settings for my sub amp. the KA-1000 THX amplifier.

sub_settings.jpg

Phase = 0°
Boundary Gain Compansation = OFF
THX = OFF
LOWPASS CROSSOVER = 120 HZ
LEVEL = A bit more then half

Does this say anything to you or to someone ?
I have totally no idea what to do with the phase, the boundary compansation and the crossover.

This is great information. Your phase should likely be set at 0, where you have it, given your sub is up front.

There are two things we can try. However, first we should find out what ARC set your Speaker Calibration Levels at. To do this you will have to look at the MRX's setup menu and check the Speaker Calibration levels. Let us know all of the levels. Not just the level of the Sub.

Then once we see those numbers we can proceed. I suspect the first test we will want to do is to set your "Boundary Gain Compensation" to 'On' and we may want to make an adjustment to the level you have your sub set at (we will know more on this once we see your Speaker Calibration Levels).

Once we try the "Boundary Gain Compensation", we can review your graphs and see if it helped, hurt or made a difference. The second thing we can try is setting your "THX" mode to 'On', however I would want to know what your current Speaker Calibration Levels are first as this switch will defeat the Level control on the Amp and we need to know what effect this could have.

Post up your "Speaker Calibration Levels" and let's figure out what to try next!

Hey Tigger,

Hereby my Speaker Calibration Levels :

Front Left = +2
Center = -1
Front Right = +1
Surround Right = 0
Surround Left = 0
Aux Right = -1
Aux Left = -1
Movie Subwoofer = -10
Music Subwoofer = -10

About the THX mode to on.
I've read that you can only may set it to on when your receiver is a THX receiver, but the Anthem isn't right ?

Does this mean that it would be better to set phase at 180 if the sub were oppositely placed i.e. near field?

Thanks!

My MRX700 is running through Paradigm Studio 60 mains, Paradigm ADP-590 surrounds, a Paradigm CC490 center channel and a Velodyne sub. I've got a PS3 (for gaming/playing Blu-ray), a Cisco PVR (TV) and Maingear PC (high-end gaming) connected to the MRX. Display is a Samsung plasma.

As I mentioned previously, in my 14 months of ownership I've never experienced any problems or unusual sounds. Just a lot of sonic goodness.biggrin.gif

I used this exact MRX 700 at the dealer, connected to a higher end CD/Blu-ray player via I think HDMI, and never experienced either of the 2 popping and static issues that I'm experiencing at home. It could be that the MRX 700 is extremely sensitive to the equipment it's connected to, which is still a major problem but something I might be able to work around.
Thanks,

The THX mode will likely set the sub crossover to 80Hz therefore I would disable it and let ARC set the crossover.

Use the volume knob on your sub and turn your sub down. Your goal is to be a few db, +/-3, for all of your speakers. You have achieved that goal with your other speakers.

Hi Beatbrother,

As both Jayray and Ninja12 already suggested, you want to turn your level down on the amp to your sub. Given it is currently at about 2 o'clock, I think I would try around 10 o'clock.

I would also set your "Boundary Gain Compensation" to 'On'.

After you make these two changes, re-run ARC and post up your new charts as well as the new Speaker Calibration Levels after ARC has been uploaded to the receiver.

We can then take a look and continue to make recommendations.

John,

Normally I would agree with you on this one... though according to the manual for the amp, it actually defeats the crossover and level control altogether and requires that the receiver set them. Obviously having the crossover disabled would be great (instead of its currently imposed 120Hz Low Pass) however, as it will also defeat the level control, we might suddenly find the levels way to high given where we are currently seeing the levels set. So I think we want to leave the THX mode off... I thought it might be an option if the levels were more reasonable.

Of course my assumptions were based on what the manual states (which may be a very bad assumption! smile.gif ) Here is a link to the section of the manual I was looking at: http://www.avsforum.com/t/1289533/anthem-mrx-receivers-300-500-700-owners-thread-tweaking-guide/12690#post_22557007

Hi Dacaesar,

Setting phase is a tricky thing. However, when the sub is positioned along the front wall, in the same general plane as the front speakers and facing the same direction of the front speakers (as probably is the case about 65+% of the time) you can usually safely assume that 0 is probably correct or at the very least a good starting place.

If your sub is elsewhere in the room it is very hard to make a general call.

And with all positions, including the front, it is a good idea to check the phase by listening to some white noise while sitting in your listening location (I've heard it suggested that if you don't have a sample audio cd with white noise to simply tune to a spot on the radio dial with no station and listen to the static)... than have another person adjust the phase from 0 to 180 as you are listening and at the point where the base seems loudest, have them note where the knob is. Than turn the knob to 180 and adjust the phase from 180 to 0 and again have them note the place where the bass sounded the loudest. The two points should be close to each other and you would simply set the knob in between the two.

This is the quick and dirty way... there are a number of far better instructions in this thread if you do a search that will help you better learn how to set phase.

If you want to balance the gain in the sub yourself, then output the sub test tone from your avr (assuming its trustworthy), and place your spl meter where your head would be. Then simply adjust the gain on the sub till the meter reads 75db. Alternatively, use a test tone from any dvd or test disc, with you processor volume at -30, and do the same, auto setup should then set the subs level pretty close to 0.

That was a reply over at avf, would anyone agree thats the way forward for me?

Yes I do have v50.25. I contacted Anthem support several days ago (earlier this week) and have not received a response yet. I filled out the web form - I guess I will try calling them on Monday. Has anyone with similar issues tested with multiple source devices? My dealer would like me to try a conventional Blu-ray player instead of my PS3, but I don't have one to compare with. Just curious to know if others have already tried multiple devices and still experienced the click/pop when muting or changing songs or losing signal (or the static/distortion issue when using HDMI or USB).

Thanks for your quick reply. We have one component in common with the PS3. I suppose there could be differences between the many different versions of PS3s out there, but the fact you are not experiencing any clicks/pops/static with a PS3 connected is encouraging. Other than these hiccups, the sonic goodness has even exceeded my expectations so I really hope I can get to the bottom of this and be able to stick to the MRX 700 as my receiver.

The MRX will set the calibration slightly differently than this method (it is more sophisticated than just using a simple sound meter). But the sound meter will get you in the ball park.

Typically you can hone in on the correct level as well if you run and upload ARC a few times (which most of us did as we were learning and correcting things). Both ways will get you where you want to be. The sound meter is a little more "scientific" if you happen to have one... otherwise running and uploading ARC a few times and checking the levels/tweaking the level each time you do a new run, will allow you to get where you would want to be pretty quickly as well.

I believe Anthem is having problems with the web-form. Call or email them. I think both the number and the email address are listed in the FAQ post on page 1 of this thread.

Hi,

As Anthem was unable to fix the problem I decided to sell it. I replaced it with a Denon AVR-4311CI and have not had any issues with any of my input signals. Please note that although the Denon is a much better receiver than the Anthem I found Anthem's ARC to be superior to the Audyssey system such that I use a Paradigm subwoofer with the Perfect Bass Kit ;-)

Good luck.

Cheers.

Ive had a meter since waaaaaaay before all these audyssey/arc etc sound thingys!

As i still have no lappie I turned arc off and set all speakers to 75db, which surprisingly was almost the same as arc had set with my sub at ref level...
