There must be something wrong, sub placement, maybe... I have SVS SB1000 which is the cheapest sub from SVS and it goes down to 20 Hz no problem.. I set it to Flat and crossover to 150 Hz...

His room could be larger also. Takes a lot of air movement to pressurize a larger room.

Agree that the room may be the bigger factor here. I'm curious.
post #13444 of 16457
Most probably as I live in a condo. Room size is about 12 x 14 ft. but open to dining room which is 12 x 12 ft. If you were going to factor the dining room, it will be 12 x 26 ft. Sub is placed on the corner opposite the tv and front speakers and close to the listening area. ARC mic was set up about 5 - 12 ft away from the sub. Sub volume is set at 1 o'clock, max volume is around 5 o'clock. This doesn't matter as I tried cranking it up and the db level just goes up but the graph still looks the same, according to ARC quick measure.

Simple question for my buddy as I do not have an MRX on hand ...

Does the channel trim adjustment allow positive increase in LFE channel level? The manual seems to imply that LFE (not SUB!) can only be reduced.
post #13446 of 16457
My room is 3648sqft total 19x16x12. I've moved this sub all around and the setting will not change.
mybe the furnature or the room dimentions?
this thing has no issue energizing my room during WOW. you can hear it from outside! its just not hitting any lows?

all setting are to factory default of disabled settings and i've set an email to SVS on this. 3648sqft total volume. "not an issue for this sub by any means" by svs

I was talking about the ARC setting. I set it to Flat instead of auto and 150 Hz instead of 120 Hz.
post #13449 of 16457
Kosmo, have you tried different placements and checked with Quick Measure or REW? It'd interesting to see what happens below that dip.

I'd chuck it in a corner.

Your SB13 should be fine down low.

Can someone please try turning up the LFE trim and let me know if it works?
post #13451 of 16457
Hi AVfile, like most receivers and pre/pros you cannot turn up the LFE independent of the subwoofer trim. You can decrease it but not increase it. The MRX series is similar to other processors and only lets you reduce the LFE to protect a less capable subwoofer.

Like with all receivers and processors there's always people who are interested in what chips are inside the box. I didn't see anything in the thread about the chips used so here's a good article that discusses what DAC, processor, DTS & DD chip as well as video chips are used in the MRX. http://www.laaudiofile.com/anthem_mrx700.html

Hello everyone, great thread here. I'm almost to the end of it!

I recently purchased a MRX 300 to use as a pre/pro and have a quick question that I cannot find an answer to.


I am a frequent user of the "All Channel Stereo" mode. My Pioneer AVR would do this mode regardless of the source. It seems as though the Anthem will only do it when receiving a Stereo signal but not something like Dolby Digital.

Am I missing something here or is this just something the Anthem can't do?
post #13454 of 16457
If you set the player to output PCM then you should be able to select All Channel Stereo, but if the player is set to bitstream and the MRX is doing the decoding then I don't think it will work with the MRX decoding the DD signal.

BTW try Anthem Logic Music it's not one of those funky reverb DSP modes. It uses the front L/R (no center) and surrounds. To my ears it's still using the fronts as stereo and just adding the same to the surrounds at a lower volume and really enhances the soundstage.

post #13455 of 16457
I will certainly give that a try.

My main concern was watching things like sports or Netflix that output Dolby Digital. I really liked watching football games and having sound out of each channel. Comes in handy for low volume listening at night with Netflix too.

Every receiver I've ever owned has been able to do this.

Other than that I must say I am very pleased with the sound from this thing. I thought my pioneer was decent but even out of the box this MRX sounds quite wonderful. Not a night and day difference but most certainly noticeable.

I'll be giving ARC a go in about two hours. Excited to see the results.
post #13456 of 16457
Everybody,

I have just received my MRX 300, and am very interested in ARCing it. I have an AVM 50, so I am familiar with the process. It has been awhile since I have upgraded that unit, so I have a question that I hope someone can help me with...

Is the ARC sw compatible with Windows 8? Are there any gotcha's that I should be aware of, or can read about ahead of time?

Any help will be greatly appreciated.

Thanks in advance...be well
Ron

The only difference I've found when running Windows 8 vs Windows 7 with ARC is that the volume level shown in the graphs on my Windows 8 laptop are lower than on Windows 7. I've run ARC several times with windows 7 & 8 and the speaker levels are the same it's just that the graphs between Windows 7 & 8 show a different level. They do display differently even though all the speaker levels after ARC are exactly the same with 7 & 8. The speaker levels and target windows for 7 & 8 are exactly the same after running ARC but the graphs show different levels.

I'm also using the latest Tripplite driver for Windows 7 & 8 for the USA-19HS key span http://www.tripplite.com/en/support/downloads/software-literature-downloads.cfm

BTW: A few people in the "Anthem D2/D2v/AVM50/AVM50v/ARC1 tweaking guide " thread have noticed the same thing but no answers from Anthem yet.

My speaker levels for 7 & 8 are:
FL: -2
FR: 0
C: 0
SL: +2
SR: +1
BL +3
BR +2
Sub -3


Windows 7 graphs with level between 70 & 80dB :






Windows 8 graphs with level between 50 & 60 dB :

Like you I came from a Pioneer (Elite VSX-92TXH). Without ARC it wasn't night and day but still a difference. Wait until you run ARC. In my room with ARC it's like someone lifted a shirt off the speakers. It's night and day. Bass is tighter and more controlled and the soundstage is huge. It makes you feel like your in a much larger space.

I have been using my MRX and liking it a lot so far...cant wait to get moved to set everything up...two weeks to go!

In channels on the mrx, what does LFE do?

Also how are you guys getting your subs to crossover at 120 automatically? every time i run mine it always wants to set it to 80hz

I've just tried to give back a little when I could as I've gotten plenty of help myself over the years! Lately I've been a bit busy... I've been out job hunting after the last company I worked for closed its doors in a rather sudden and surprising nature! Fortunately, I just started a new job this past week and I suspect I will be quite overwhelmed for the next few weeks as I learn and settle in to my new role! Needless to say, I will continue to try and help out when I can but I may be a bit scattered for a while. biggrin.gif

I hope that a few of the users who've been helped in the past, have been, and will be able to, step up and help out the latest round of New Owners with their questions and entry into the world of Anthem and ARC. If only everyone helps out for a few months after they posted up their first charts, the cycle of help should live on as long as our MRX's do! smile.gif

Jayray (an MRX and Anthem Signature owner) and a number of other Anthem Signature owners were kind enough to help out the early MRX owners, myself included, even though some of them didn't even own an MRX! That really says a lot about the character of the people who buy Anthem's technology and I'm glad I've been able to give a little help back to a few new owners that joined the Anthem family after me.

Hey Tigger, Congrats on the new job!! I hope things work out for you. Just wanted to say I have not forgotten about all the help you, Jayray and other experts (whose names escape me at the moment) have given in setting up my receiver. I don't hang out here much (but I have been enjoying my MRX500) and I really wish I had the technical understanding and expertise to help out, but I am afraid I might give faulty advice if I tried. All the same, I appreciate that you and the other experts take the time to help out around here.

Alrighty, just got done running ARC. I did not set speaker distances beforehand. I'm assuming ARC auto detects but I have heard otherwise.

I have the following equipment, PSB Image T6 Towers, Image C5 Center, cheap Polk Surrounds and a Klipsch RW-12D sub.

Could someone take a look at my graphs and let me know if anything stands out? I'm still learning about ARC and am pretty overwhelmed with all the manual options!

Thanks!


post #13463 of 16457
Hey everyone...just picked up my 300 today..just using it as a preamp
I will be running arc once I pick up the keyspan adapter
My question is..I'm trying to find out how to change the audio when I'm watching satellite TV..it keeps showing pcm 2.0. I'm trying to get Dolby digital from HBO..I scroll down to d.d in the audio setup and select it but it keeps going back to pcm 2.0?..I know its just a setup malfunction on my part...right now its on 2 CH stereo and I can get all the stereo sounds by scrolling thru..but those only apply to the 2 CH pcm modes (anthem cinemea..all CH stereo. Etc..but no Dolby digital..can some one guide me thru this setup?
Love this avr..can't wait to run arc!

You'll need to set the speaker distances manually either before or after running ARC(it doesn't matter if it's before or after) .

Nick from Anthem explained why ARC doesn't set the distances:http://www.avsforum.com/t/1289533/an...#post_21195160
Quote:
The reason for not including distance measurement with ARC is that there is a PC in the system. It's impossible to know the latency each PC creates therefore no way to correlate distance to time. We realize that requiring a PC is less user friendly but there is no other way to obtain the same level of room correction performance.

Another potential reason, even with no PC, is that standing waves could skew sub distance measurement depending on measurement method. We've seen receivers which set distance automatically act as if the sub is 40+ feet away when the real distance is much less. Of course, it all depends on the room and sub placement.

Your sub is good down to about 24Hz, but the graph shows it rolling off at around 40Hz . Looking at the specs it has an adjustable crossover from 40Hz to 120Hz. Also looking at how it's rolling off at 40Hz I'd guess you have the sub's crossover set to it's lowest setting(40Hz). On the sub's top control panel you have a crossover bypass switch, you should turn that on to disable the crossover and let the sub play down to 24Hz.

The guys in this thread who know ARC say you should shoot for a 120Hz for the sub's response cutoff. You'll have to move the sub around to see if you can get to 120Hz.

LFE in channels is just the .1 LFE channel and it let's you lower the .1 LFE content in movies if it's to strong for your liking. This is totally independent of the Subwoofer channel level.

To get ARC to automatically set the sub to 120Hz you'll have to move the sub around a bit or see if a different location get's you to 120Hz.

The MRX display shows the audio and video input it's receiving, so the reason your seeing 2.0 PCM on the display is because your cable box is outputting a 2 channel PCM(stereo) signal. You'll have to configure your cable box to output DD. The signal coming into the MRX has to be DD, then you'll see Dolby 2/0, or Dolby 3/2 on the MRX display.

BTW what cable box are you using I might be able to help you set it to output DD?

ill try moving the sub a bit thanks.
But im still confused about LFE channel vs Sub channel, wont they both going to do the same thing?

The 'sub' channel is actually made up of two 'sources', the redirected bass from mains that have a crossover set - and the Low Frequency Effects channel encoded within movie sound tracks. The sub plays both.
Music contains NO LFE, it's only on multi-track movies. It's the .1 in a 5.1 or 7.1 sound track.
Some AVR/Pre-Pros have the ability to redirect the LFE channel to 'capable' main speakers, if a subwoofer is not present - but on most systems it will simply be lost without a sub.
The LFE channel spec goes upto 120Hz - so you should try to ensure that the sub can output those frequencies - however some posters prefer a setting of 80Hz (not much at the higher frequencies - and they can make the sub localizable)
The 'sub' channel in effect has multiple crossovers - one for each 'main' group (if they come out different, 60Hz for Left + Right, 80Hz for Center, 100Hz for Surrounds - just possible examples) and a Low Pass for the LFE (120Hz or 100Hz or 80Hz, according to taste) - all of this is hidden away inside the AVR Bass Management circuitry.

Regards, Mike.

Hello everyone,just picked up my 300 after reading this thread from page one for the last three months,so far so good! I have it all set up with my harmony one..no problem, just using as a preamp,will run arc after I get the keyspan in a few days..just one question..I'm watching sat/TV my audio shows 2 CH pcm. I'm trying to get D.D
From HBO,but I can't get it when I scroll down to Dolby digital and select it just goes back to 2 CH pcm..how do I set up sat/TV to that audio setting?..
post #13470 of 16457
Disregard that last post!.. Thanks
I'm using a dish net VIP 211
I think I figured this out
Been saving for this for 3 months!
Can't wait to run arc!.. All is good !
