I have a Logitech Harmony One, and it works great so I'm sure the 900 will work for you as they are basically the same remote with the 900 adding the RF functionality.

I basically adjusted the "Power On Delay", currently I'm using 13000 and it seems to be working well for me.

To make this adjustment, add your MRX as a device on the Logitec Harmony and...

Step 0) Log into your Logitech Harmony Remote Software
Step 1) Select the "Devices" tab in the Harmony configuration home screen.
Step 2) Find the MRX in your list of devices
Step 3) Press the "Settings" button
Step 4) On the "Device Options" screen, select 'Adjust the delays (speed settings)' and press the "Next" button
Step 5) On the "My AV Receiver takes the following times to respond to commands" screen, adjust the "Power On Delay" to '13000' and press the "Next" button
Step 6) Finish the adjustment configuration wizzard and update your remote with the new timing settings.

Please see the attached screen shots that highlight the steps listed above

Thanks Tigger I just made the adjustment on my Harmony One's software. I still need to upload the changes to my remote. Can you explain why this delay is needed?

The MRX takes a certian amount of time to power up (more than the remote allows for by default). So if you have the remote set to do the following:

1) Turn on the MRX
2) Turn on the TV
3) Turn on the BluRay player
4) Set the MRX to your BluRay Source
5) Set the TV to MRX Source

With this sequence you would probably find that all devices were succesfully turned on and that the TV's input is correctly selected for the MRX, however, if the MRX had previously been on another source (say your cable box) that it is still on the cable box. This is because when the remote sent the command to switch sources, the MRX was still booting up and did not receive the change source command.

The fix, when the MRX is first powered up, the remote must wait till the MRX is fully booted before it sends the command to change sources. I played with a few different times and found that the 13000 seemed to always work (yes it is a long pause... but it seemed to always work).

Now once the MRX is up, you can switch between sources without requiring a long delay, so we only adjusted the "Power On" delay. The other delays stayed the same, so if you switch between the BluRay player and your Cable Box and back to the BluRay you will find that the switch happens without a problem and quickly. This is because the remote know the MRX is already on and does not implement the "Power On" delay.

I did find that it seemed when I had a memory stick with music on it plugged into the front of the MRX that the Power On time needed to make sure that the correct source was selected was longer than when the memory stick was not plugged in. I suspect this is because durring the booting up process the MRX stops to index the memory stick before it completely boots. So you may find that if you never have anything connected to the MRX's USB ports that you can shorten the time a bit.

Hope this helps.

Yes, thanks. As soon as I upload the new settings I will see if I have to adjust anything. I do know the MRX is set to turn on last and I may have to change that.

Random interference/noise in Front Right Channel.

So I am on my 2nd MRX300.
I had a 700 that I returned for the 300 as it better fit my requirements.
My first MRX300 I returned as it locked up about 50% of the time if I used the rear IR in port while trying to power-on.
If I could get beyond that, the rear IR-IN worked fine.
BUT - the lockup would require me to pull the AC from the unit.

The 2nd MRX300 has an issue with the front right channel. I get a large amount of introduced RF noise that comes through the speaker. There is a certain amount of noise in EVERY channel, but the only noticeable noise heard from the listening position 8ft away is from only a single channel - RF.
I swapped LF, and RF and the problem follows the amplifier - not the speaker or cables. So it is surely the amp.

It is channel independent - I don't have any analog sources - and all channels have the same noise.

It's almost as if it is a cheap receiver where there is crosstalk between analog sources - say a tuner and an analog CD player. I wouldn't expect this kind of noise in a (mostly) digital receiver.

I didn't notice it in either the 700, or the previous 300.

Ohh.. and that rear IR-IN? Still locks up with power-on. This forces me to use a front mount IR blaster.

This is indeed quite good advice, but I've been listening to what ARC sets for a little over a week now and though my perception has improved, it's not enough to make it sound right to my ears. As soon as I raise the sub level several DB it sounds better and like what I'd expect. I too have measured with my Rat Shack meter after ARC and the sub indeed does measure 3-4 DB lower thant the rest of the speakers. We are also told not to do this becaus the mic on the Rat Shack meter is not as accurate in the low region as the ARC mic, but it seems now there is some truth into what's going on here.

-Glen

How do you measure the sub level with your meter? Do you use the internal sub level noise tone? Cause when I try to use that the SPL reads waay too loud. Do you use a test tone CD or something? I mentioned this to the guy at Anthem and he said they know the sub test tone level is wrong. However, I don't seem to be able to find any other reports of the sub test tones being too loud.

I just used a good calibration disc to confirm what ARC did after the fact. All the main channels are about spot on and the sub channel measures 3-4 DB lower. I think it is a known fact that if not using ARC and calibrating the MRX manually with it's internal test tones, that he sub tone is way hot.

I have just increased my sub level on the 300 from -4 to 0.
Would this be the correct way to do it?

Please tell me more about this RF noise. I also have a random noise in my front right channel. Mostly noticed while watching recorded TV shows from DVR. It is like a click/pop up I don't know how to describe it. I was hoping it is something to do with the popping other people were talking about and will be fixed with software. Mine occurs when the codec's are not changing. Random times during the show. I am getting impatient waiting for software update.

If you rewind the program you are watching and play the section with the odd popping noise again, does it re-occure? If yes, can you verify by watching the front display of the MRX that it doesn't momentarily loose the audio signal and regain it (so it will be the same codec, but the MRX goes Codec, No Codec - audio signal lost, Same Codec very quickly)?

I know my cable box tends to drop the audio signal and glitch once in a while; especially it seems on recorded material.

The pops/clicks occur repeatedly if I rewind. Same spot in the recording. Also no visual change on the MRX display. Something like "Digital 3/2" but it never changes on the display. No visual or audio drop outs. Just noise that shouldn't be there and only in the right front channel. That is what makes me think it is not the cable box. Always only right front.

Interesting. In particular that it is repeatable when listening to the same DVR'd show in the same location over and over.

Just as a sanity check, you said the pop only comes from the right front... have you actually gotten up close to the front left or one of the surrounds to see if it is occuring there as well but just not as dominantly?

Is there any digital noise in the picture or frame shuttering when the pop occures as if some of the digital packets were lost?

Maybe I am missing something here, but if it is ONLY present in this recording, and ONLY at the same exact time, then the noise is present in the recording and has nothing to do with the receiver used to play it back, regardless of it being an Anthem or other brand.

That was my first thought. It is in the recordings. Possibly a problem with my DVR??? I am unsure if that is the answer. It happens on a lot of the recording. I never really watch a show live so I can not say if it happens there or not. Yes I have also put my ear to every speaker and it is only out of the right front. That is one of the reasons I responded to the earlier comment that he heard RF noise out of the right front only. Sounded like my problem. I am by no means says that I know it is the MRX causing it. Just suspecting it.

I believe he gets it at other times as well, however the fact that it is repeatable in the same place does tend to heavily suggest that it is the recorded show with a glitch in it.

I find that when my cable box, for some reason, is having issues... namely for some kind of digital signal loss, I will occasionaly get the codec dropout pop sound. I'm not sure if on short dropouts the display has time to update that the signal was lost or not... it may not as I think it takes the MRX a second or so to display this.

However I would have expected the pop to come from all speakers. I have however found that the codec "pop" is not always as pronounced from all of my speakers as the one that I sit closest to. Hence I was curious if he had actually walked around and listened more closely to each speaker.

My current expectations are that it is the codec "pop" sound he is hearing, but wanted to ask a few questions before I jumped to a conclusion.

I would be interested to know if he hears the classic codec "pop" that a lot of us have heard when he say: pauses his DVR, waits a second, then hits play. And if so, does the pop sound similar? and does it come from the right speaker mostly (only)?

If f468357 does experience the normal pop, it would be really nice to know if the one he hears during normal watching seems simliar (with perhaps a stonger front right dominance) or is a totally different sound.

So last night I did some more listening. I watched 4 hours or non recorded TV. No pops were heard. If I pause the live show, wait until the MRX display changes from "digital 3/2" to "no signal", I hear the expected codec pop. This pop is louder than the one I get when listening to recorded shows. It is also in all channels. I am guessing it is the same noise at 1/5 the level due to only coming out one speaker. Another difference is that the pops on the recorded shows have no audio interruption. Just the random pops. Even on the codec pops (pause and play) I don't get the pop if I resume play before the MRX switches codecs. If I pause (sound drops out), resume play (sound starts again) no pop. Maybe about 1/2 second pause. I assume this is the same for everybody. It sounds like maybe it is the DVR causing the problem and not the MRX. Maybe I will take it back to the cable company and try another one.

I've heard that this might be fixed in the current beta release. We'll have to see.

I have not been exactly thrilled with the sound of music coming from my MRX in two channel format... so I thought I would fiddle a bit.

Some of my observations and question.

I modified an existing ARC calibration... I checked the full range speaker option on the LR fronts (100v3s) and eliminated the subwoofer (Seismic 12).

After crunching the numbers and uploading... the results have left me quite confused.

I am used to the way two channel music in 2.1 "Movie" mode sounded but the same audio in two channel 2.0 "Music" mode sounds quite different... First of all "Music" mode is quite loader. Normal listening for me in "Movie" mode is around -14... but in "Music" it had to be turned down to -27. The shouldn't be, should it?

In "Music" mode I am missing out on the lower end frequencies of my Seismic... but the mid range is fuller and the high frequencies seem to be exaggerated.

Why is all this happening because I disabled the subwoofer in "Music" mode in ARC?

Personally.. I think music sounds best with ARC disabled... for now anyway.

I am glad it is not just me! I have been struggling with this for a while now. I like to listen to music with just my studio 100's, no sub. So I have been running arc with music mode with just my two front speakers. I have not been able to get it to sound right to me. Same as you, high freq. very bright, had to increase base, and I always have to lower the volume a lot. I have finally given up and just listen to music in movie mode with my sub and surrounds. I am hoping it will be fixed at some point with a software upgrade.

Post your charts, both Movie and Music. Also, check your Listening Mode Presets, Bass and Treble settings, and Dolby Volume for the relevant Source(s).

This is consistent with what others have shown. It is clear that ARC tapers off L/R speakers in order to blend the subwoofer. What I don't understand though is what happens in the Music mode when you want your L/R full range. I have yet to see a chart where L/R bass is corrected for peaks but otherwise left intact - target curve always goes down at 80 or 60 or whatever the high pass frequency is.

Can ARC respect 'no subwoofer' mode in Music and set the target curve that uses in room bass response of large L/R speakers to their full potential?

In the chart you specify only L/R for music but you still say '60' for frequency. Maybe you should lower that - how low can you go?

Like Eking... My full range x-over option has been chosen for the LR fronts. So, in theory, the 60Hz cutoff is irrelevant.

Change the 60 to flat in "music", recalulate and try that.

Hmmm, wasn't sure and not sure what "flat" setting he is referring too other then the "flat" setting for the sub/s? Tomorrow I will finally be hooking my 300 up and will have a better understanding.

I think the problem is that we don't know what target is used for L/R without the sub in the music mode. When you check the charts, the bass is clearly hacked off (the measured response for L/R has way more bass than the target curve), making me think that 60Hz setting still applies. That's why I wanted to see if setting L/R to 'flat', recalculating and uploading would improve things. Based on the L/R measured response, the speakers have much more bass to work with than the tapered target curve displayed above.

Sorry for my poor explaination. Change the response cut off for the front speakers in music profile from 60 to flat. That will give you full range to the fronts.

RF noise is just that - think about it as an FM tuner that doesn't tune into a station properly - you can hear voices, but can't make them out.
Now this noise is intermittent on the RF channel only and seems to be pretty independent of volume.
It is the amplifier channel, not the source, not the wiring.

There is a certain amount of white noise evident primarily from the tweeters on all channels if you put your ear quite close - this level is pretty consistent regardless of volume.

The clicking/popping is from ALL channels when the digital stream turns on/off. This is 100% repeatable. I notice it with my SA PVR just by pressing play/pause - every transition there is a noticeable clicking sound, and delay as the stream gets decoded. The front panel will show this by going from no signal to dolby digital or whatever it is receiving.
