(2) With the MRX turned off (or in standby), is the HDMI signal passed through? I've been told some receivers do that, some don't.
(3) Is there an easy way for my HTPC to remote control the MRX? Preferably through LAN, or at least through serial cable? I'm mainly interested in being able to read and write "volume" and "mute". I need to be able to do these things with my own (Windows) software.
(4) Will the MRX be able to handle "funny" resolutions like e.g. 1080p with 24.000Hz or 25.000Hz? Will it at least passthrough not-supported modes?
(5) I'm wondering whether it's worth it to wait for the MRX 900? Does anybody have a list of things where the MRX 900 will be better than the MRX 700? Will the MRX 900 case have the same depth as the MRX 700? (my rack is limited in how deep a receiver it can handle)
The only guarantee someone at Anthem will see the questions is by sending them to Anthem. I go for months without reading posts. Only doing it now due to recent MRX launch, on personal time and heading out after this.
1. Depending on the player there might be some luck with MRX video in Through mode but I wouldn't count on it. 3D that you can buy today does not need increased bandwidth and I have no idea when next-gen with flicker free refresh rates will be on the market. HDMI v1.4a 3D recognizes 3D flag and sets video processor bypass mode. It's in the cards for MRX via software update, I'm hoping before year's end.
2. No, and in cases where it's possible it's a menu option. Leaving HDMI powered on when the rest is in standby still requires 10-20 times the 4W standby consumption limit imposed by many standards. Some countries are even looking to a 1W requirement.
3. Serial commands are slated to be expanded considerably in around three months. For now they are:
?' Returns the product identification string (MRX500 vn.nn' for the MRX500 and MRX700 vn.nn' for the MRX700 where n.nn is the internal firmware version
SN?' Returns the product serial number in the form XXXXXXXX. where each X is a numerical digit 0-9.
'PnP1' power up zone n (if not already powered up)
'PnP0' power off zone n (if not already powered off)
PnP?' returns PnP1 if zone is currently on, and PnP0 if the zone is currently off
PnSx' switch to source x in zone n (for Zone2 only x=0,19 are valid)
PnS?' returns the currently selected source x in zone n as PnSx'
PnM0' mute audio output in zone n
PnM1' unmute audio output in zone n
PnVMyy' set the main volume in zone n to yy
PnVMU' increase the main volume in zone n by 1 step (similar to volume up on remote)
PnVMD' decrease the main volume in zone n by 1 step (similar to volume down on remote)
4. Consumer electronics (CE) standards only.
5. MRX 900 is a considerably different beast with AVM 50v genes, an amp circuit all its own, and at least a year away. Only the individual can decide how long to wait for anything - the "newer better things will come out" cycle never ends while life passes by. It'll cost more than twice the MRX 700 and on price I always said for maximum enjoyment and least likelihood of buyer's remorse get the best you can afford and pretend that anything beyond that doesn't exist.
