The AVM-40 and the AVM-50 as currently shipped do *NOT* have the necessary processing power to handle ARC. A hardware upgrade would be needed to add the additional DSP.

An audio DSP upgrade (adding the additional DSP ARC needs) would not be sufficient to enable internal decoding of the lossless Blu-Ray bitstreams in either the AVM-40 or AVM-50. Those bitstreams can only be passed over HDMI V1.3. HDMI V1.3 requires newer HDMI port chips than are currently in the Anthem products. The HDMI driver chips are on the video board. So you would also need to replace the video board (plus, most likely) additional audio processing portions as well. The video board is the single most expensive replaceable component in the AVM-50 and in the D2. So I think it much more likely Anthem will offer an ARC-specific audio DSP upgrade for the AVM-40 and AVM-50 that has nothing whatsoever to do with decoding the lossless bitstreams.

Q1: Are the XLR connections on the amps and preamps truly balanced?

A: Yes. All three pins of the XLR connection are part of the circuit, which means it's a real balanced connection. (If pin 3 is sent to ground or left open, as is sometimes the case, then an XLR jack is an adapter, not a balanced input.) The purpose of balanced connection is cancelling out certain types of interference and ground loops.

Based on other info, it looks like it will also be available for the AVM-40. Apparently it will NOT be available for the AVM-30 (unless of course you upgrade the AVM-30 to an AVM-50). I don't know why this would be the case since ARC is offered for the D1 now, so the HDMI jacks and video board are not necessary for ARC itself. But perhaps the add-on "second DSP", required for ARC in the AVM units, plugs into the video board for power or whatever.

It looks like Anthem is perhaps as much as 2 weeks away from publicly announcing this.

The ARC portion of the upgrade will retain the D2 ARC upgrade kit pricing of $399, but there is also a hardware upgrade required to add the second DSP.

One report puts the total price of the ARC upgrade for the AVM-50 at $800 (hardware change plus ARC kit). Obviously any such pricing reports are not solid as of yet.

So far I've not heard anything which suggests the hardware upgrade would be dealer installable. I.e., it appears that you would need to send your AVM-50 in to Anthem to get the hardware upgrade installed.

1. I have several large cardboard Characters in my room. Should they be removed or just left to let ARC adjust to their presence?

2. My understanding is that if you run Standard for ARC, you can save a file and open it later in Advanced and recalculate to get the graphs. If not interested in the graphs, or adjusting anything after ARC is there any reason standard shouldn't be run?

You can just run Standard. If you like it, fine. If you don't, you can use the same measurements in the Advanced mode for adjustments and recalculations. OTOH, I prefer to measure in Advanced mode since you get a "more considerate interface."

"Truly" balanced means having double the components in the balanced circuit and not many ssps will do this.

Previously, I used to do it inside the main room but sometimes, found myself in the way between the speakers and the mic and I used to move around to minimize the effect.

Is there a concensus on this?
