A:AnswerJust one RCA to HDMI at a time via A/V (5-RCA cables) input. If you use external A/V to HDMI converters (typically less than $20) you have ample HDMI ports for more devices. Consider the Amtake 1080P RCA Composite CVBS AV to HDMI Video Audio Converter Adapter.
A:AnswerAccording to the Onkyo website, this receiver does support HLG pass through:

A:AnswerIt should work fine. Test the battery or replace with good working batteries. Make sure you place the batteries in the correct or right direction. You can bring the remote to best buy and ask them to test it in the store with one of there similar model receivers.
A:AnswerNo it wouldn’t work. If you did it that way, you’d only have all the speakers going when you use Bluetooth or internet. Zone 2 can not play from hdmi sources.
A:Answerchromecast built in is audio only, same with the built in airplay. if you have a video chromecast i suppose you could plug it into one of the HDMI ports, it has a ton. 6 i think?
A:AnswerI don’t know what banana plugs are but there is a separate area for subwoofer. Bare wires for speakers have an area also. I set up 7 speakers and subwoofer with no problem. You’ll have to ask Best Buy about banana plugs.
A:AnswerActually there is a hidden menu option that allows 4k enhanced mode that is required to pass HDR. Press BD/DVD and power together twice to enable it.
A:AnswerYou can adjust the speaker levels once you have calibrated everything one by one but as far as turning the volume up on those two sets of speakers you have to do it through the main settings not the quick settings
A:AnswerYour speakers can handle 145 W Maximum, and this receiver can produce 100W average power, so you should be fine. The maximum power recommendation is given to protect the speaker from damage, so you don't want to be too close to that number. What you're getting at is speaker efficiency, which is the amount of power it takes to produce a given loudness level; the Max power spec does not address that at all. But 100 Watts is plenty of power to drive nearly any speaker adequately, so don't worry about it.
A:AnswerNot sure what you mean by the question. I have an Apple TV 4K hooked up to the receiver because that's one of the only ways to get Netflix Atmos support. You can also use HDMI Arc if your smart tv supports it to send the audio signal to the receiver. Not all smart TV's support Dolby Atmos though.
