Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 103

How do I find the "CEC" function so I can turn this feature off?? It is supposed to help with the internet radio freeze problem if you can turn this feature off.....

Thx in advance... I have not found this item anywhere in the manual or in the set up menus...

I've been reading through this thread and want to make sure I understand something. If I'm listening in stereo mode using ARC, can I listen to just my L&R speakers without the sub?

I would like to post my charts but not sure how to bring them up here.


Rick

Turn it off in ARC.

You can have two configs, one for movies and one for music. Set music to use only the FR and FL speakers in the Target window and do a calculation. Then upload. Pick music for the source you want to play stereo from.

I haven't used a PC in a while other than running ARC... but I think you hit the print screen button>open paint or photoshop>create a new document and goto edit and paste (cntrl v).

The you can post the jpegs here using the "Manage Attachments" button.

I am a long time mac user I will try to get them up here because i would really like you guys to see how they look! I do have a question about the targets? Arc set my mains to small 60hz, center small 60hz, rears small60hz and my sub is set to 120. I did set the sub to flat and tried it that way but the last time i ran arc it set the the sub back to auto! It sounds great to me so this time i didn't mess with it. My question is at 60hz is this ok for my speakers? or should i change these setting? I would hate to destroy what arc did

Im trying to upload my charts!

See page 29 of the manual for the procedure.

What type of sub do you have? The red measured curve is dipping quickly from 35 Hz and that could be due to a switch on the back of the sub such as frequency crossover or cutoff. This should be set to the highest freq, usually 150 or 180 Hz. prior to doing a measurement. If it was set to some low freq. you should set it to off or highest freq and do another measurement. Your other speakers look very good. Also post a pic of the target window in ARC.

What are the benefits of ARC running sweeps twice? Once for music and then again for music? Why not just sweep all speakers once and then process base on speaker choices? Am I missing something?

Depends on your set up. For music I had a slight change (closed my TV cabinet). Some people want only LF and RF. Depends on your needs

Whelp guys, I solved my powering on/off issues! Turns out, the Sony Ericsson PC Suite software for my cell phone that I don't use anymore was interfering with the com port (COM2) I had set for the Keyspan adaptor. I kept wondering why my Keyspan would alternate from "idle" to "busy" every few seconds even with nothing hooked up to it. I took a lucky guess that it was the Sony Ericsson software since it's one oft he only USB devices I use that has it's own separate software. Anyways, I don't use it anymore so I just unistalled it. Bingo! That was it! No more going form "idle" to "busy" for the Keyspan. Stays at "idle" consistantly until I hook up the MRX and start tranfering data. The MRX now powers on and off with no issues anymore and ARC recognizes the MRX now even in the powered "off" state. Awesome! I'm stoked! \\m/ Well, so I thought....

Just when I think I've got one problem solved I unlock another one! Now I seem to have upload failures every other time I try to upload new ARC settings. So, the frustration continues. It seems the Keyspan is locking up when these upload/verify failures happen. The light on the Keyspan will stay glowing green and shutting down ARC does not remedy the prob. I then have to unhook the Keyspan and hook it back up for it to reset itself. Then it all seems good and the next upload process will go off without a hitch. I don't remember how many ARC uploads I did last night, but it seems 1 out of 3 uploads would fail. At this point, I'm stumped at what to do next. I am already in contact with someone from Tech Support through email, so I will ask them about it. I have attached some screen shots of a couple of the upload failures and the code number it lists if anybody else knows what they mean. Thanks to all who can give further insight to this.

Perhaps you're still having an issue with your COM port or PC power saver.

Hi John,
My sub is a Paradigm pd10 not great but for the size of my room its ok.
I have Paradigm studio 40s up front a studio reference center and paradigm mini monitors for rears. I turned the setting to the highest freq and volume knob to about 12:00 like you all suggest. Here are the posting of my targets! If you have problems reading them let me know and ill try to send it again. Also is it ok to have your speakers all set to 60 in the target window?? Just dont want to damage my speakers.

Thanks, Rick

I know you have tried a lot of things, but maybe one of these will help...

1) I find that the USB cable tends to be loose or wiggle loose from where it connects to the Keyspan adapter. Make sure it is well connected before EACH run. (just moving your laptop a little will cause the cable to come loose).

2) Make sure your laptop is plugged into power and that your power settings are set to not sleep or shut down when plugged in.

3) If you think there is any chance your power settings might be kicking in, press the shift key on your keyboard every 20-30 seconds until the upload is complete.

4) Make sure the keyspan is set to the same speed as the MRX.

5) Try setting the MRX and the Keyspan to the next speed down for communication.

6) If you are not sure that you have a totally free COM port and you are using a laptop, you probably have a built in Modem. As almost no one uses the Modem anymore and it is probably using a COM port in the 1-6 range, you can disable the modem (freeing that COM port) and then have the keyspan use that port. The port will typically not be shared as it was configured for the modem and will help make sure that you don't have any other conflicting software/devices trying to use the COM port.

7) Try turning off Windows Firewall, some people have found this helps.

Hope perhaps one of these will help you!

60 is just fine, trust ARC.

I have a PDR 8 in my 2.1 setup and your response looks better with the PDR 10. Not sure what else to suggest, it should sound quite good. As for the 60 Hz. setting in ARC, leave it. For too long we have been told to set speakers to settings THX recommended many years ago and since then correction programs have gotten quite good at setting better ranges. So trust ARC, Anthem has spent a lot of time developing the program from hundreds of rooms and with differenct speaker measurements and this is what they came up with. Probably more than what THX did to come up with their recommendations.
John

Hey thanks guys! It does sound good! I am one happy camper! I am actually glad my rotel died.

Did you do this after you ran ARC or before you ran ARC? IOW, are the latest ARC Charts you posted include the setting turned up to the highest frequency? If you set the setting to the highest frequency after you ran ARC, then you will need to run ARC again.

No i did it before i ran arc.

Ok. Well, I agree with jayray's assessment. Your charts look good. The only future change I would consider, if I was you, is the sub. Your sub is dropping off after 35 Hz which means you are missing out on some good stuff down low and in the subsonic area. Anyway, congrats on your new purchase and enjoy.

What could i do to correct this???

I don't know the specs of your sub. Maybe your sub only plays down to 35 Hz. If that's the case, then the only thing that you can do is get a new sub.

The PDR subs don't go down very far, 35-40 is about it.
John

Well getting a new sub is out of the question right now. It really sounds pretty good to me at least its what im used to. Do you guys think that the MRX300 is enough power for my speakers? I know with 5 channels it is only putting out 60 watts. I would think that would be ok but not sure. The 500 only does 75 per channel so i dont think it is a real big step up from where im at now but i could be wrong. I only bought this a week ago and the dealer said if i wasn't happy i could exchange it. Would it be a big difference?

Crank it up and see how it performs. What speakers do you have and what's the size of your room?
John

I have fronts paradigm studio 40s, center studio, rears paradigm mini monitors
Room size is 12x14

They shouldn't give the 300 any trouble. These receivers have been tested with speakers up to the Sig. 8 and without a problem. Now depending on your room size, the power should be fine. Don't rush out quite yet until you've done a fair amount of listening.
John

If you are enjoying what you have now, then I would say don't make any changes. The most important thing is that you are happy with what you have, and as long as you are, then the rest doesn't matter.

As for the MRX300 having enough power for your speakers, you will have to answer some questions first.

1. What SPL are you trying to achieve at your LP?
2. How far are you sitting from your speakers?
3. What is the sensitivity of your speakers?

For example, if you are trying to achieve 85 db at your LP and you sit 9' away from your speakers and your speakers have a sensitivity of 90 db, then you will only need 6 watts of power. If that's the case, then your MRX300 will have absolutely no problem at all achieving that goal. As a matter of fact, it will probably be bored out of its' mind, and ask you "Are you serious".
