DENON model no. HEOS Link HS2 Wireless Pre-Amplifier

The listing

It's a thrift store find. I've never tested it. It's in great cosmetic condition. The white power cord came with it, but I doubt it's original equipment. I plugged it in with that cord and, in front of the DENON, the blue light blinked around 20 times, then it turned amber and blinked amber a couple of times, then it turned solid amber. That's as far as I've went with it. I edited out the barcode ...it's still there.
