You can change impedence using Advances Setup, pls refer to manual, i think its holding Straight button, then, hold Info button, then, press Power; try and see.
I can confirm that this worked as I just purchased an RXV-473 for RM1900. Updated the firmware to 1.64. Hooked it with Mordaunt Short LR and C speakers with Kenwood Active Sub + old Onkyo surround speakers. YPAO callibration was very well down. But I custom fine tuned it a little. Few comments and help needed on this unit as this was my first Yamaha. I have 2 Denons, 1 sold and one taken away by my brother.
1. The on screen display's graphics are really ugly. Anyone agrees with me?
2. Maybe I haven't get used to Yamaha, but it seems not to automatically detect 2.1 or 5.1 from the source. previously from my Denon, when it received 5.1 channel (AC3/DTS/TrueHD/MasterAudio) it will automatically switch. But for this RXV673, it kept the previously used setting, eg when I was playing stereo, once I changed to another source (on and off the unit), it will retain whatever scene I was using for all stereo playbacks. Similar goes to 5.1 channels. I have it on Standard Movie, but when I playback (also, turned on and off the AV, coz play it next day), it will retain the previous scene, in which this time, I played a 2.1 only movie, but it went to surrond decode. Anyone knows a way for it not to remember previous scene but to just automatically use the source signals?
3. The most annoying would be this. My unit is connected with Bluray/PS3 and a Media Player. When I was listening to music, be it via the Media Player or USB (front), it worked perfectly while the TV is turned on. To conserve energy, I turned off the tv and viola, the player stopped to output any music. The red HDMI out will be blinking. Only after I turn the TV back on, it resumes. Tried HDMI control/HDMI passthru, nothing. Any advice?
In overall, i would say that this unit performed fine. Love the Dialog volume and lift increase. DRC works well too to keep the sound in an acceptable level, but I turned it off

The LCD font is kinda large and ugly though
Thanks in advance for any help.
