A:AnswerThe remote works without a TV, if that is what you are asking. You can also use your smartphone with the Denon remote app. If works well and will let you see selections and functions on it easily.
All Denon units sold in North America are only 110/120V models. All 220V and 240V units are sold for other regions like Denon Europe and Denon Asia Pacific.
So Best Buy lists the unit by wattage which is why the Best Buy listing shows as the AVR750W. However, the true model name for the unit is AVR-S640H. They are one and the same just labeled differently by the dealer. I hope this helps clarify any misunderstanding.
A:AnswerHi. This AVR (AVRS640H) is capable of single zone only, which means it will not play in an interior room and also on the patio simultaneously. However the Denon 7.1 models like AVRS740 or AVRX1500H do that capability.
Unfortunately a direct USB iPod connection to the receiver is no longer compatible. You would most likely need to use a 3.5mm to RCA cable to connect your iPod to the receiver. The front USB is capable of reading music from a thumb drive and playing it.
