I don’t see any HDMI inputs. How is video inputted into the receiver?
This AVR was released in 2004. Someone must have found a bunch of unsold units in some warehouse. $699 is an insanely high price for such a dated piece of gear that has been sitting around for 18 years; you can find similarly capable old AVRs at thrift stores and pawn shops for $20.
If it was $69 it might be fun to pick one up for the garage; it’s not every day you can find a NOS piece.
To answer the above question, there is no HDMI. It’s all component connections, which many devices nowadays do not have.
