Your sub is just fine.

Hi guys
What do you think
Should i go flat or auto
Thank you for any responde





post #13145 of 16457
Auto as right now your sub is not producing the lowest freq. The way it drops off so fast would make it appear you still have a filter on it turned on.

What filter

I think the filter refers to the crossover in your subwoofer.

Thank you audit13
The crossover in my sub is to max. 150Hz and the MRX 700 adjust to 120Hz

Is there a way to disable the crossover? What about the phase?

It looks like you sub is rolling off below 50 hz. What brand/model sub are you using?

It is a Paradigm Seismic 12

Given the quality of your subwoofer, I'm surprised its rolling off below 50. Have you tried adjusting the phase or moving the sub around to minimize the roll off?

Your charts look good to me. Your sub is dropping off below 30 Hz which may be fine if that's the limit of your sub. I suggest you check the specs for your sub, and if your sub's lower frequency limit is 30 Hz, then all is well. Based on your sub's frequency response, "Auto" is the best setting for your sub.

Based on what I got off the website for your sub, your sub is performing as expected.
Subwoofer Cut-Off Frequency Variable 35 Hz - 150 Hz

Thank you Ninja 12.
The sub sounds good to me ..
One more question
Do i have to adjust phase at Sub after ARC.?
The sub are placing on side wall -no in the same line with front speakers
Thank you

You have to set the speaker distances manually, either before or after ARC, it makes no difference - but ARC does NOT set them for you. If you have some measuring equipment you may find that adjusting the sub phase can improve the sub to satellite crossover (make it more seamless). Without the appropriate equipment, it's probably better left at 0, but you may be able to tune it by ear for smoothest response. Best of luck.

Question, I have a PC12-NSD sub, the specs say that the Freq. Response is 18-130Hz +/- 3dB. Ideally, what should my sub graph look like? Flat from 20-130? I don't want to move this thing around chasing something that is not attainable.

Thanks for any responses.

I know what a solid sub graph looks like, I'm asking if my sub is capable of that. I don't want to spend a ton of time trying to get a solid sub graph if it isn't possible to begin with.
post #13158 of 16457
Your PC12-NSD should look good down to 20Hz as long as you don't have any nasty peeks or nulls that are caused by placement or room size like a square room that's 15x15 for instance.

Pleas tell me about my chart with Sub ..
What do you think ..?
Thank you
post #13160 of 16457
Are my eyes deceiving me? I could swear that I saw evidence of the occasional missed frame while watching Boardwalk Empire tonight - mainly evident on panning shots. I'm sending 1080p 24 out from my Oppo 93 through my MRX300 to my Lumagen Radiance and thence to my Sony VW95. To double check it I've been watching some Fringe on Blu and I think I've seen it there too. I'm new to Anthem - only had my receiver for a week so am just getting used to it. I have the latest firmware. Is there an issue with 1080p 24 with my particular combination of hardware?

Thanks.

Hi Pixelman, the Seismic 12 will play below 20Hz, but it has a steep roll off after 35Hz. What I'm saying is it will be audible to around 18Hz, but at a much lower decibel. You need to disable the sub's crossover since you should be using the crossover in the MRX. Since the Seismic doesn't have a crossover disable switch you need to turn the "Subwoofer Cutoff "" knob on the sub up to it's max of 150Hz. This will get the crossover out of the way and essentially disable it (this is also how you disable the crossover on all subs without a crossover bypass/disable switch). Then the MRX can control the crossover. By leaving the sub's crossover at it's min of 35Hz you have two crossovers one from the MRX and one from the sub (at 35Hz) that's preventing the sub from playing below 35Hz.

Disable the sub's crossover by setting it to it's max of 150Hz and rerun ARC.

Actually the crossover was at sub to max (150 Hz) and i using the crossover in the MRX..120Hz
post #13163 of 16457
Hey folks,

I'm 90% sure that I will be getting an MRX 300 within the next few months. ARC and the reputation of the dealer I'd be buying are the main factors, so I'm not to worried about potential little bug as I know I'll be treated like a top notch from the dealer smile.gif

Do you guys expect anything from Anthem for their AVR at the 2013 CES? And if so, aside the probable 4k compatibility, do you expect anything major?

cheers

120 in the MRX (actually ARC targets) is the cutoff not the crossover. The cutoff is the max EQ freq that ARC will apply to the sub curve.

If you're sub's crossover is already set to 150Hz, then it's the steep roll off below 35Hz that you're seeing. Unfortunately you can't do anything about it because it's performing the way the sub was designed to perform.

Thanks.

If I remember, it might be due to you haivng the MRX set to 1080P instead of through. But that is an assumption on my part. What do you have the video out set to on your MRX? Also, are you at the latest firmware?
post #13169 of 16457
Hi, yes I have the latest firmware. I also have VidOut1 set to 1080p 24 but unless I'm being extremely dumb I can't find any way of changing it while still feeding the MRX a 1080p 24 signal. If I switch off 1080p 24 in my Oppo then my MRX gives me all kinds of options including Through because it's receiving a 1080p 60 signal. But if I do this then I don't get 1080p 24 delivered to my projector.

If you set it to through and leave your Oppo the way it is, the MRX will pass through the signal as it sees it meaning if it gets a 1080p/24 signal, it will still pass it though. However, you will loose the OSD.
