Anthem MRX Receivers - 300, 500, 700 Owners Thread & Tweaking Guide - Page 484

post #14491 of 16453
So I tested what would happen if I lowered the max EQ frequency, seeing as I didnt really have any measured issues over 1k. I figured it might improve the filtering within the smaller range. Seems to be the case:



Movie is the standard 5k max EQ, music is set to 1k. Its not dramatic, but its clearly an improvement, it tracks closer to the target from 100-500. Notice how even though movie had it set to 5k, theres absolutely no difference between them in the 1k to 5k region. But it still needed to be set to the lower max EQ manually - its didnt automatically increase the filter resolution just because it didnt do anything from 1-5k .So for this channel at least, there was nothing to lose. Its worth giving a shot, no need to re-measure anything, just open a saved measurement, figure out how low you can go, reduce the targets, recalculate and reupload.

Getting REW to drive individual channels via HDMI involves installing an ASIO driver (I use ASIO4ALL). When fully configured it gives access to the eight individual PCM channels, including direct LFE input. The AVR bass management will still direct low frequencies to your sub, as per normal.

Check out this thread, where AustinJerry has put together a very detailed (step by step) guide to configuring ASIO with REW.

I have also experimented with altering the Max EQ frequency - and it can yield good results. At the moment I have the setting at 5kHz (max for MRX) as my Left & Right Mains are exhibiting a wide dip between approx. 2kHz & 4kHz - that ARC is correcting very nicely. When I get some more time I will set up my measurement equipment and try to figure what is causing the dip. If I can get rid of it - then I may reduce the Max EQ Frequency so that ARC is able to devote more resources to the low frequency area. With all that said, I'm really pleased with my system at the moment, and plan to catch on some movie watching smile.gif

That may have been me. Off hand, that doesn't appear to be any newer than the last one I tried, but I don't know for sure. Regardless, I'll give it a try next time I feel like messing it. I'm completely sour on the whole thing and don't want to get my hopes up. Thanks! smile.gif

Hello again

is the anthem analog output has a strong enough signal to drive a pro amp like qsc or behringer without having to install a samson s-converter or art box

If you're going to use ARC when playing CDs, you'll probably want to bypass each player's DAC since the mrx needs to digitize incoming signals in order to apply equalization.

Furthering my frustration two separate computers that have serial ports - the usb microphone doesn't work, even though in one of them it did initially?
Never fear, I am getting the keyspan when in comes into stock in Sydney I am told tomorrow.

And as I did have ARC working on a computer at one stage, I can attest that it did a great job adjusting for my room with my old speakers. That's why I am even more frustrated, I know how good it works and I've upgraded speakers that I want to hear sing at their best.

Oh well, couple of days won't kill me.

And the frustration continues.

I purchased a keyspan adapter and that did miraculously work so my laptop can indeed talk and control my MRX 700. However it still will not sample through the ARC usb microphone. I thought I had the microphone working as the volume gauge was working when I went into set up microphone. Turns out on further investigation this volume response was coming through the internal inbuilt microphone on the laptop. So it appears my usb microphone may be kaput. At least I hope that is the case because otherwise I am stumped.

It is still quite frustrating as it worked when I first installed and set up my receiver. When I upgraded my front speakers and re ran ARC all of a sudden it is not working. So I'll get onto Anthem and see if I can obtain a new microphone.

I bought the receiver used online so there is no warranty and no dealer to contact. Damn.

Just for anyone else who is going through problems with their usb-serial adapters, it appears that the MRX receivers may be a bit finicky and just get the keyspan straight up to save heartache.

Let us know how it goes with tech support from Anthem. I think you can only obtain Anthem warranty support if the used unit was purchase from an authorized Anthem dealer unlike some manufacturers.
post #14505 of 16453
Just spoke to someone at Audio Active in Melbourne who are the distributors in Australia I am led to believe. They will sell me a replacement usb mic for $60 plus courier costs, so fingers crossed that I get the microphone and then it all works.

Wow my MRX 300 crapped out. Video does not pass through and I can't enter setup menu. Even by pushing the button on front panel. I tried unplugging from power and still no luck. When I turn the unit off it passes video to tv since I have CEC on. Tried upgrading firmware...nothing. My 3rd unit. My Anthem / Paradigm experience has been a nightmare.

Anthem tech support suggested restarting the AVR by holding Tuner down while powering on... this didn't work either. Looks like I'll be onto my 4th damn unit.

Wow! 4th unit, my suggestion is to change brand. I have had my MRX 700 one week after they came and never had to replace.

Like Brian, I have had my MRX 700 since original release with no issues. I know that I would not have your patience....I would have changed to another option after unit 2 crapped out.
post #14509 of 16453
Problem is I don't know what other good options I have to drive a 5.1 system. I'm using the MRX for the surrounds and a MCA 30 for the front 3.

Here is the kicker. I also returned my MCA 30 yesterday for replacement as the speaker knobs on the back binding posts looked chewed on and one failed to screw down tight as the plastic cap / knob was slipping on the metal screw. It appeared used.

I asked the shop for a loaner so I'm using a Denon 3300ci? It sounds a little thinner...but I haven't played with all the settings. Also the -20 db on the Denon sounds like -30 on the MRX.

I am shopping for an anthem receiver either the 300 or 500 to replace my onkyo tx-nr818 . I have a few questions

1. being from Canada the 300 retails for $1099 and the 500 for $1649.99 and i saw a mrx 500 in a pawn shop for 1199$ all accessories seems to be there except for the box. A quick call to anthem revealed that if the unit is still under warranty it is not transferable so is it worth it to go for a used unit at that price and hope that it won't fail 2 month from now or go for the brand new 300

2. I stopped by an anthem dealer this afternoon and he told me that because i have an amp to drive my mains that i would get better bang for my money to go with a marantz or integra av processorplus an amp for the surround because i would get better audio and video circuitry and better scaling than with a receiver. Also i would be paying for power on a receiver that i would not use what are your thoughts on this?

Thank you for your help

You can get good and bad sound from XLR and RCA. XLR connections/cables do not automatically provide superior performance in my opinion.

Unless you have some very long cable runs, you are not likely hear any difference between XLR & RCA.
post #14515 of 16453
I sympathize with you. I am on my 3rd MRX 700 since Dec 2012. First one had amp protection errors after 2 months. Second one had failed video card after 1 month - this one was clearly a refurb. I have had a new one for about 2 months. Had to reset it once and am keeping my fingers crossed. I thought about switching to Marantz but don't want to give up the sound quality.

Unless you need the few extra features of the 500 go with the 300. You have amps for the fronts and the 300 will easily drive the rest of your speakers. I use a 300 and all my channels are driven by separate amps. If you don't need the extra features of the 500 don't pay for amps you'll never use.

It's sad that it does appear common practice for Anthem to pass b-stock / used items for new. If I'm paying $2000 for a three channel amp, it should not come with speaker knobs all chewed up like I did that is obviously not new. Or, having my $2000 "new" MRX 700 come with wrinkled manuals and battery acid leaking out of the remote from the batteries left in the remote from the previous owner. But like you, I want the sound quality.

Completely agree. I went from MRX 700 to 300 because I did not use any features the 500 or 700 have. I use a home theater PC which IMO is the best solution and does everything but play sacd. I thought I might listen to HD radio, but realized I couldn't stand listening to the quality of radio on a "nice" system.

I agree with Leggaire about the MRX300, it will be fine if you have an amp for the fronts. smile.gif My 500 does a good job on its own in a smallish room.

In the UK we have to pay the same numbers in pounds sterling as they charge in Canadian dollars - which is a lot more in real terms, though quite a few are sold over here.

It is hard to work out the likelihood of failure on the MRX series. There do seem to be quite a few reported on here - but then again maybe owners with problems are more likely to find these forums and complain.

My first unit, an MRX300, was sent back because the front right channel didn't work. When the suppliers got it back they tested it and it worked perfectly and asked if I wanted it back.Err, no. Probably a dry solder joint somewhere which got jolted back into place on the drive back. It was probably re-sold as new and maybe the present owner is happy, but maybe not. smile.gif I'm not sure I'd risk one without a guarantee.
