Anthem AV receiver at CES? - Page 40

Known recently revealed issue to go with it... if MRX is in Through mode it doesn't play nice with 24p-enabled Oppo BDP-83 with 24p. Easy fix with nothing to lose - don't use Through mode in MRX, use Auto or 1080p instead. Output resolution can be changed on the fly, but not while it's trying to sync. Software engineers are looking into it. 1080p plus Through does work with Anthem BLX 200 though. All a mystery for now.

Nick, question on ARC. ARC sets my crossover fairly high considering I have Paradigm S-6's. Does it make sense to use two subs as not to localize the sub when using a high crossover. It sets mine crossover at 100hz but others have had it set higher. I have no problem with high crossovers because it makes it easier on the amp in the Anthem but if you use one sub and the crossover is above 100hz the sub becomes easier to locate. Thanks for all your insight.

also, other than audio one, can anyone tell me other GTA based anthem dealers?

thanks.

All that and then some can be changed while the only setting that would disable ARC is changing "Room EQ" from On to Off. Before changing anything, listen with the ears not the eyes.

The only other issue might be max speed, but I think ARC works all the way down to 1200 bps (slow), so not a problem.

Should be here in 2 weeks, which is right when my theater room is done.

I can't wait.

p/s I'm using it as a pre-pro

and if i want to set the crossovers at 100hz, i can set that up in arc first and then have it calculate everything based on that?

Finally, if you own Revel Salons, they don't need any equalization except below 300 Hz where the room dominates what you hear If you own good loudspeakers, you should focus on correcting the low frequency acoustical interactions between the loudspeaker and room.

There are some things equalization can and cannot do:
1. It can help with some, but not all, loudspeaker problems. With comprehensive labo- ratory measurements (like Figs. 9–12) to work from, equalization can be used to make a good speaker sound better. Once a loudspeaker is in a normal room, we lose the ability to measure it in ways that allow us to be totally analytical. Without knowing what is wrong, we don’t know whether equalization is the right solution for the problem. For example, equalization can change frequency response, but it cannot change directivity, yet together they determine the basic shape of a room curve. Poor directivity control, as a function of frequency, can only be cured by using a better loudspeaker. In general, if the speaker has been competently designed, it should probably be left alone at frequencies above about 300 to 500 Hz, whatever the room-curves look like. Since all manufacturers claim to be compe- tent, consumers have a problem. Automated equalization systems that are not dedicated to specific loudspeakers have a problem. They have no special “inside information” about the loudspeakers, so those that make adjustments over the whole audio frequency range are, as they say in ’Vegas, rolling the dice. Caveat Emptor.

I have noted in research by both Dr. Toole and Dr. Olive related to room correction/equalisation and well designed/engineered speakers (like Paradigm/Revel etc. who use extensive use of anechoic chambers to properly evaluate their speakers) their expert opinions on where to properly apply equalization.

I have just ordered an MRX 500 and hopefully my store in Ottawa will get it in soon.. so I am busy doing technical research on ARC in order to maximise its potential application within my listening area.

In the Dr. Olive Audio Musings blog he has a comment:

In Dr. Toole's Science in the service of art paper (page 25) he states:

So my question is (and I will definitely test my hypothesis using the default and my own high limit(s) when I get my MRX500) would ARC react better if I restrict the high frequency default correction range to say 500Hz as opposed to the current 5kHz? Curious as to any testing/thoughts/opinion.

Cheers.

P.S. I posted this in the MRX thread as ARC has less processing in the MRX models compared to the Statement series.
