Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 211

I use full range and no sub and bass is excellent. Mine are paradigm studio 100s.

Could there be a setting I'm missing? The source is Apple TV via HDMI.

I don't use Apple TV so perhaps someone else will be able to help you.
John

I will try playing a 2 channel CD tonight to see if that makes a difference

That's what I use for music.

I want to send IR commands from my control system to MRX 700.
I have M-980 remote that sends signal to RF gateway.
My control system will send IR signal to Xantech 789-44 connecting block.
This takes in 1 IR inpout and provides IR to 4 devices.
I have two choices here.
I can use IR flashers that are cheap and they stick to the front of MRX-700. Since my reciever is in a closet this is not a problem
The other option is to plug in IR signal into the external IR In port of MRX 700. Is the any better than using IR flasher?
I have read that I cannot just take an IR signal from the connecting block, use a mono cable and plug it into the MRX 700. I heard that certain carrier frequencies need to be stripped before the signal can be sent to MRX 700.

Xantech claims to make a 28EXT Ternal IR Input adapter that strips the IR frequencies so the IR signal from the connecting block can be passed to the External IR input of components like MRX 700. However this adapter is expensive.

Let me know if you have any suggestions for me.

Edited original post, this occurs with CD player too

The sub built into the speakers may be the issue but then I don't really know about those speakers.

Let's see your graphs. I just went thought ARC on my Def Tech 2000TL with Tigger holding my hand all the way. First we found that I had my subs turned down too far. Started turning them up and never looked back. What adjustments do you have foer the subs in each tower? You might glean something from my posts and Tigger's replies. Two channel really rocks.

I'm really looking forward to seeing how the tritons sound w MRX and ARC as I've been coveting a pair.

Took delivery of my sub today. :-) Been playing around with ARC and its own EQ. Not entirely sure that I like the results. For this ARC run, I disabled the built-in EQ. I'll play around a little later with it again. ARC set my speakers to 60 and the sub to 100. I set it to Flat, as well. Thoughts?

Once I started with some movie-watching (How To Train Your Dragon), I ended up turning up the sub from 30 to 45.

Try moving your sub around. You have a huge dip that can probably be minimized with location. You can see that ARC tried to raise that dip, but can only do so much.

Hit the Auto Scale button in the ARC widow to see the sub graph at the same scale as the other speakers and post again. The dip at around 35-38 Hz will affect what you hear and feel so moving it around in small increments and using Quick measure to find the best spot is recommended.
John

I have to agree with the others, you have to experiment with different sub locations to fix the nulls. Location, Location, Location will definitely be your sub's friend. Definitely us Quick Measure as you are moving your sub around. Good luck to you.

Hi all, I've been reading the forum for a while now learning as i go as I set up my 700 with a set of focal dome 5.1 speakers. Finally loaded new USB version and 50.12 and ran arc for the first time today. All sounds good but would appreciate any feedback for my graphs. Cheers Gerry

Someone with more experience than me may disagree but I think you have hit it right on the money.

Your speakers look good but your sub is nose diving at 50 Hz. This will give you anemic LFE. What are your sub specs? Also make sure you have turned off any crossover settings or subsonic filtering. We want ARC to hear the sub without any processing done in the sub and that includes any EQ.
John

Beta Firmware 50.14 has been released. The release notes are below.

Changes since v50.12 production release:

1. DirecTV US satellite receiver can have an issue when playing 3D while connected through an AVR (any brand) instead of straight to TV. Although it is their issue (DirecTV admits this on their web site), and TV model and software also play a role, we made a change for MRX which may help regardless.

2. Handshake issue with Mac Mini DVI source - fixed.

3. Fixed issue where surround-side and surround-back levels were swapped contrary to corresponding values displayed in setup menu.

Contact Anthem if you think this will help with a problem you're experiencing.

John

Focal dome sub specs and setup at back of subwoofer attached. When i ran arc for the previous graphs, I had cross over at max setting but subwoofer volume at ~50%. Will crank up sub volume and rerun. Any other changes before I do this? regards Gerry

Your first pic of your specs is for some reason not coming up, can you repost it? Maybe it is just me?

I'm not sure you need to adjust your volume on the sub to dramatically... turning it up about 5-10% may help a little but I don't think that is an issue.

Your Crossover knob however should be set to 170hz or as far clockwise as it will go if it is not already.

Without having your ARC file to play with... I can't say for sure, but you might try something we don't usually recommend... you might try and play with the advanced settings on your Targets window.

Something like...
Subwoofer High Pass Order: 8th Order
Subwoofer High Pass Frequency: 42

I don't have experience with built in subs but turning up the volume won't fix the drop off at 50Hz, only positioning. Looking at the sub specs, it seems clear you don't have the capacity to go much lower with higher spl. The chart is showing you what the sub can and is doing. Positioning wouldn't add much to the response curve.
John

Ok, I got the specs to open in another browser... of the IE8 wouldn't open the graphic...

Looks like your Frequency response on the low end goes only as low as 42Hz... so I think your not going to get much more out of the bottom end.

You can try my suggestion of playing with the Advanced settings to see if you can squeek a little more out of the low end... but it looks like you are about as low as the sub was designed for.

Thanks for the feedback. Makes sense. I'll get what i can out of it and then maybe go hunting for how I can fit a second lower sub in the equation. I had a play with the arc file as suggested and recalculated and seems like the fit is better. I'll try some other positions as well. I should get a chance to plug these in on the weekend and will repost my findings.
Still sounds great but you guys have given me tweaking disease. Thanks mate!

Can you post up your new graphs, targets window and advanced targets window?

my 300 isn't switching any composite video inputs. I have the kids wii hooked up to the game input. Main Video in is composite and audio in is analog. It is passing audio. Advanced setup for main/rec composite input is set to composite 1.

wii works hooked up directly to tv.

all hdmi inputs are passing video.

any thoughts?

Just a quick sanity check... cause I know the first time I was connecting everything to the back of my MRX I got a little lost...

You are connected to Composit 1 in (circled in the attached pic)?

yes

Figured, but I love it when it turns out to be a simple fix!

Have you tried another composit video in like composit 2? Or have you tried connecting another composit video source like your BluRay player to Composit 1 to see what happens?

I tried all 3 composite inputs with same results. I have not tried another device. I doubt it will make a difference.

It was displaying the correct resolution of 480i. So it is detecting the incoming signal. However, it isn't passing through.

I'm not sure if it is a bug or a set-up config issue. I'm pretty sure I've got it set-up correctly. I'd rather not factory default and reinstall everything, but I think I'm heading down that road.

I'd like to trouble shoot all possible angles before.

If it is a set-up user error I'll gladly take the hit. If not, I'm on my 2nd 300 and getting tired of the little bugs.

Are you using composite out to the TV or just HDMI? Not sure if the Anthem converts composite to HDMI??? If you haven't tried it, try composite out to the TV.
