I needed this for some 4-ohm speakers (it has 4, 6 and 8 support, might have more I didn't notice). If you bi-amp your fronts you get 210 watts which is good. Frustrating setup, it wasn't detecting my 4K@60 HDR signal. Bought new 8K certified cables, tried everything. Turns out it only needed a firmware update (which is a PAIN and now have new cables I didn't need). To update your receiver you need their stupid software on your phone and create an account. The more I write, the more I want to give this a 3.5 stars. But now that it's setup, I'm happy.
