Theremini connections

Hi, New member here.  I am about to receive a Theremini in the mail today, can t be more excited.  It comes with a 15 watt practice amp also.  My question is...can you connect to a home theater receiver, i have a Denon 7.2 channel via usb to hdmi or 1/4" male to RCA inputs?  I can t seem to find an Aux input on my receiver so i might have to connect to an RCA input.  thank you.

the aux 1 and 2 inputs on my receiver are HDMI. so should i use my rca inputs for it to work?

I think it will be possible to connect the theremini to the Denon through the RCA inputs. But I do not think this will be good for your Denon and speakers.
