I just received my new STR-DA4ES receiver this Saturday, and so far everything is working great. However, the default Command Mode of the remote is AV2. So that I didn't have to reprogram my Pronto, I changed this Command Mode to AV1. Everything seems to work fine in this mode except that the multi-channel input function selector doesn't work when the remote is in the AV1 Command Mode...at least on my receiver. If you own a STR-DA4ES or 'DA7ES, could you run the following check for me? First, set the Command Mode of both your remote and your receiver to AV1 (for the remote, it's under the "RM SET UP" menu, for the receiver, it's under the "CUSTOMIZE" menu). Once you've made this switch, see if the Multichannel function selector works (press "FUNCTION" on the remote and scroll to "MULTI CH"). Like I said, this function only works when the Command Mode is set to AV2 on my system. This glitch isn't messing me up now because my SACD player is two-channel only, but I guess I'll have to reprogram my Pronto once I do get get multichannel SACD! Thanks!!
