Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 255

Thanks for the tips Bob. I will try them out and hopefully get it sorted out. Just out of curiosity though, how can I turn off "pass through" mode. And is there a setting where the video section can be disabled completely?

I don't have an MRX, so someone else here will have to help you with that.

Hi,

I have also returned to 50.12 primary because of the freeze of the system when going from BD input to TV.

I also registrate the clicks between CD tracks. Same issue was apparent on CD players for about 25 years ago, but in 2011 a solution on this should not be rocket science based.

To be honest I would expect a solution on these issues ASAP. It cant be that hard to fix.

Thought I'd transfer to this page.

If you only have a 5.1 system you won't be able to use any of the modes that will convert 5.1 to 6.1 or 7.1. If you are worried about 3/2 showing up and not showing the .1 that is ok. That is just how the MRX shows what it is hearing. Might be a limitation of the screen size or something else but the .1 should still be playing.

Hello all,
I recalculated my ARC set up with my sub set to flat. It definitely increased the sonic experience from the bottom end! This may be a stupid question but why didn't ARC set it to Flat when I did my microphone calibration?

Because Flat is not a safe choice for all subwoofers. If your subwoofer does not have internal protection against the lowest frequencies it could bottom out when sent those, certainly producing distortion, and possibly damaging the sub.

Ok,
Thanks Bob. I am glad that my sub has protection, and I never go below -30 when I watch Movies.

Aahhh, OK, thanks!

Does the MRX support pure analog pass-through? A friend is bringin over a high end CD player/DAC and we were wondering if the MRX will allow pass the analog signal straight through without digitizing at all. We will be sure to turn off ARC and any level corrections.

Sorry if this is a repeat Q, but I couldn't find anything on it.

Ok guy's
One more question on my sub (Rythmik F12SE) I have a toggle switch that can be set to 3 positions. 14,28,or 20, it also has a Damping switch that has 3 options, Low, Hi, and Mid. here is what it says on there web site, I have it set to 14, and Hi as per the instructions.

The bass extension controls enable the user to customize the frequency response of the low end. This puts control back in the hands of the user. The controls customize a high pass filter, which attenuates frequencies below a given frequency. If set to 14 Hz, bass below this point will be filtered. The damping control determines the slope, high damping providing the steepest slope.
My question is by setting my sub to Flat (in ARC), will this interfere with my Sub setting on the Rythmik? Also my Sub has a Rumble filter built in, wich I think is the protection feature.

did some more testing and nothing helped. i actually got even more screwy with changing the output resolution form 1080p25 to 720p, 1080i, etc. so i did 2 factory resets. i through the menu, and another with the tuner button.

the issues are still there and i know for certain the mrx is doing something weird. with the scaler output directly to the pj, the video is fine. as soon as i turn on the mrx (that only has hdmi audio connected), it screws with the video. i don't even know how this is possible since all my sources are connected to the scaler and output directly to the pj. what the heck is the mrx doing to the signal that will alter it even without using the hdmi output?

in any case, tech support knows about it and we'll see what they say. there is no way of turning off the video processing on the unit. all you have is pass through, auto, 480p, 720p, etc. i wish there was an all off button.

in any case, im trying to keep the scaler output direct to the pj, but now im wondering how i can get sound to the mrx. i want lossless hd audio, so what do i need to feed the mrx. my scaler passes all signals along and has an optical toslink out. i don't think that carries hd audio but i may be mistaken. anyone know how i need to rig this to get it working again?

No. All inputs are digitized.

Thanks for the answer but it seems that if I have a 5.1 system that I should be able to choose for ex. 5.1 EX or 5.1 DTS or just DD 5.1.

Ken

I believe those will automatically detect. For instance, you can't choose DTS 5.1 if it is a DD 5.1 stream. The MRX will automatically decode DD5.1 if it is indeed DD 5.1 and the same goes for DTS 5.1, etc... Unless your BD player is decoding it for you. Make sense?

Make sense now, I just wish the display showed it, instead of just 3/2. My new SVS PB 13+ is shaking the walls even though the 500 doesn't display the .1.
Thanks again,
Ken

You got it! My Sub 2 shakes some **** too. I actually have had some of the nail heads in the sheet rock pop out. Enjoy!

While you guys are on the topic of MRX display. Does anyone know if there is a display difference between any of the Dobly Digital codecs?

I always see Dolby D 3/2, as expected, but how do I know if this is the TrueHD found on some blu-rays or a lesser version of the Dolby Digital codecs?

If I remember correctly (I need to confirm) if it is TrueHD or DTS-MA it will show that. If it isn't it will show DD 3/2 or DTS 3/2

I had the same problem. My unit stopped responding to where I had to disconnect power. Annoying

Turn room comp off as well before ARC, having this on was causing distortion on heavy bass scenes with my 13 Ultra. I have my gain at about 11 o'clock and ARC set my sub level to around -9, sounds fantastic.

Enjoy your early Xmas present!

If at 11 o'clock your level on the sub is -9, you probably would do well to adjust the level down further... aim for between -3 and 3, however -6 to 6 is also ok... -9 is pretty extreem.

One exception, if you setup your rear/height speakers as Zone 2, the audio will be passed to those speakers (when used with Zone 2) will remain analog. They are not processed at all... not even if ARC is enabled.

Tigger,

What is the actual effect you're trying to mitigate by having the Anthem AVR set the sub volume at +-3 rather than +-9?

You would want your subs High Pass Filter (the 14, 28, 20 switch) set as low as it can go, so in your case 14Hz. This means that you can play music as low as 14Hz before the sub automatically starts to apply its internal filters to eliminate any lower frequencies.

As for the Damping switch, sounds like this is how quickly it rolls off the High Pass filter (how steep the slope is of the filter). I'm not sure why this is so necessary, but where you have it should be fine.

As for ARC, as long as you had the switches set before you ran ARC, then ARC will take them into account and you should have no issues

Thank You!

There are a number of things this can do (some are perhaps less important in practice)...

1) The less the MRX needs to process a signal (in anyway, including levels) the better.

2) If the subs level is to high, then the MRX will reduce the line level it sends to the sub to compensate for the sub level being so high (hence the -9 level setting). This means that you are sending a line level to the MRX that is weaker than necessary and then amplifying it more at the sub... of course you are also amplifying the noise that was picked up on route from the MRX to the sub a lot more than is necessary as well. For example. Lets assume that the MRX can output a line level signal of 0 to 20 (arbitrary scale picked for simplicity), now lets also assume that your sub can amplifiy a signal on a scale of 0 to 100. Last lets assume that on route from your MRX to the Sub you will incure 2 units of noise. Now lets assume that the ARC wants to hear 500 units of sound.

Case 1: The MRX sends a line level signal of 10 and the sub is set at 50, then we get 500 units of sound. (we will call this the ideal setting). We also note that if we ave 2 units of noise on route, then when we have the sub at 50 we have produced 100 units of noise after amplifying the line signal by 50).

Case 2: The sub is set for 100 then to get 500 ARC would need reduce line level signal to send only 5 units. However, we still pick up 2 units of moise on route (a much higher Signal to Noise Ratio, 5:2 then Case 1 which was 10:2). This means we now are multiplying our noise by 100 and have produced 200 units of noise (twice Case 1).

Case 3: The sub was set 33 then ARC would need to boost the line level signal to 15 units to get 500 units out. This actually helps improve our noise issue as our Signal to Noise Ratio is better than even Case 1 at 15:2 wich produces a noise of 66 units. However, with case 3, we are sending a line level signal that is so strong, it may in some cases clip or cause other issues if the equipment attached can not handle it.

The example above is very simple and uses an arbitrary "unit" system that does not represent anything in the real world, it is simply to provide an example of how one system, a path with noise and a second system can interact to produce a constant desired level.

3) When a level is pushed close to the limit of what the MRX can do (in either direction), it may impact ARCs ability do its job as the resources need to fill a hole or clip a peak may not be adequate when the system is pushed to an extreem, yet may be perfectly adequate when the MRX can play a bit with the level in a more modest range to assist with also adjusting peaks and valleys better. Lets say that you have a Peak that is 16 units high and ARC has the ability to adjust the eq level up or down 10 units, as well as it can adjust thee over all speaker level +/-10 units. The total combined combination of the two is 10 units in either extreem. More than enough to compensate for the 16 units of correction needed. However if the sub is set so loudly that in order to balance the levels of the speakers with the sub we have to adjust the sub to -9, this leaves us only 11 more units that we can use to attempt to correct the 16 unit peak we need to knock down. We are going to end up 5 units short of what we need. Of course if the sub level were turned down, then the MRX has a bit more room to play with the level and the eq to take care of that spike. We can now use the eq's 10 units and 6 units of level adjustment to get rid of the spike. Of course if we lowered the level of the sub to help with a spike, we may need to boost other areas or match the levels of the other speakers to compensate.

Remember that settings required for one speaker also need to not impact ARCs ability to help the other speakers and set their levels to match the whole system solution. So if you can get the levels to all be close, it gives ARC more freedom to find a better solution.

4) Many people assume that if they turn their sub up all the way, they will get more bass. This is, of course, not the case when using ARC... at least not if ARC can help it. It will simply send a lower line level signal so that the output of the speaker matches the level that ARC wants to hear. Sort of an equal and opposit reaction

5) Some of us can't help but tweak something to death... and we like to think that 0 is perfect... so we aim for it but recognize that hitting 0 is near impossible so we just go for close

There are probably more reasons that I'm not coming up with off the top of my head... and of course the examples above are actually far more complex than I just made them... so keep that in mind as well.

Tigger,

I posted the last question because the information you offered seemed to be at odds with the advice I had previously received.

I'm trying to figure out the 11 o'clock setting. The knob on the back of the SVS subs in question pulls up different menus. The volume is the only thing to control when in the gain menu so how do you arrive at a dial position?
