I think for A2040, 6 ohms is the lowest.

I check later bcos now not home yet, not sure 6ohm is the lowest it can go

I have changed my speaker impendance to 6 Ohms. No option for 4 ohms. These speaker impedance are only for right and left front speakers right?

nope, effective to all spkrs

Really curious is it necessary to change the ohm settings ?

Just discovered that the wifi for a2040 is g and not n. Initially i try to set from my room but cant set, thought the wifi distance is to far but took down n put next to my wifi router still cant set n finally got it by setting my router to g compatible

U r right bro.no setting for 4ohm lowest is 6ohm.

my RX-V677 received a new firmware 1.50 which unlock 4k/60p 4:4:4.

finally!

Wah! got new firmware?

Tonight go back and update.

Huh how to update?? The v677 can connect to internet directly?

got lan port ma... adui rtfm rulez

haha...yeah, i know got lan port, but never got around bother with it...haha. I thought it's only for some online radio services.

Sorry I can't find the upgrade firmware in the setup. Where is the setup?

You need to press and hold the 'Straight' button on the receiver when powering up the receiver itself to activate the options. Read the manual.

Thanks. I have misplace the manual.

Anyway, I DL the manual from net. Than seems like nothing happen after shift over to "update-network."

Than I read back here taizi@ccf wrote firmware update ver1.50 ??

But my av firmware is 1.64 ? That is nothing to update right?

What is yours?

Auto update been awhile.
My 473 also did auto update before but failed and almost brick it. Lucky can do manual update and fix it.

Apa ver?

Forgot already, is just minor upgrade. But itchy hand go update.

As far as I know the latest FW listed at Yamaha website for RX-V677 is ver 1.50, released 19 Feb 2015. Unless you got your model No. wrong or someone updated the wrong FW for your AVR, I don't know how you ended up with ver 1.64.

Or another possibility is when you pressed "update-network" (Assuming you are connected), it updated to a very new FW which has not been listed yet at their website.

Sorry my bet.

I check wrongly the model. Not RX-677, It is RX-673. I even DL the wrong manual. But the process update is similar. The new firmware is 1.84 for RX-673.
