Works and functions great like the other model 45 but with a output rca, and sounds clearer, power button is on the back though. Well worth the money.

Works well. I am using it as a soundbar amplifier in a cabinet under my TV. I use an optical DAC to feed it on the Line input, but it needs a 20 db (Amazon) audio preamp to get the level correct. I subtracted 1 star because of that. The line input does not have enough gain. The remote works well - I used an $9 amazon IR extender to feed it under the cabinet.

El dispositivo es bueno. Pero no todo es bonito. Lo que no me gusta es la conexión bluetooth que es muy reducidad. No te puedes alejar tanto como dicen.

I used to use big clunky full-sized AV receives for the random places in our house where I needed some tunes. Now I use these. I have one that controls my speakers on the deck and this one handles our outdoor TV. They are easy to setup, compact, and work exactly as they should. I even mounted this one with strong velcro inside my tv cabinet. Love that it has individual bass/treble adjustments as one of my others just has general tone settings. This one even has mic inputs in case I wanted to throw an impromptu karaoke party. This unit looks nice and doesn't feel cheap. It's actually a tad larger than I expected and has more weight to it than I expected. Overall, I expect it to last. Is the sound quality as good as my legacy, 40 pound THX AV receiver? Probably not. Do I need theater quality sound for watching a game on the deck? I do not. These deliver plenty of power and quality that far exceed their price point. I can't comment on the bluetooth range on this as i'm currently using it hardwired from my TV. But every other function on this works as it should so I would think it would live up to expectations.
