I think this box only has outputs to feed an Amp

That Pyle should work ok..but I have had mixed (pardon the pun) luck with Pyle's products..some work well and over the long haul, others have failed and let me down. If that seller is a legit Pyle dealer and offers full warranty it would be worth a try..otherwise steer clear.

The transformer I recommended is cheaper and as long as the Yamaha receiver isn't blown out, it will work fine and "future proof" any later replacements.

Greg, generaly speaking, when you are at "line level" (Before the amplifier inputs) is is ok to tie outputs together. It is AFTER the amplifier (speaker outputs) that tying together is a very bad idea. smile
