Bluetooth connection!

Mutes 3 seconds after audio ends. Maybe more than 3 seconds or less, but it feels like it turns off immediately after the songs have played.

Pros
  • Receiver and amplifier
Cons
  • Requires power outlet

Not the best I've ever had.

This is the third model of this model and like the others it has died. I have several of these boards and I know what I'm doing. They don't linger, but for a few moments. I think they don't like 4ohm speakers even though they state in the description. They didn't warm up, they just died. Everything the same.

Pros
  • Home Theater
Cons
  • Neutral

This 3rd in this model died like the others. I have several of these boards and I know what I'm doing. They don't linger, but for a few moments. I think they don't like 4ohm speakers even though they state in the description. They didn't warm up, they just died. Everything the same.

Pros
  • Audio source: optional MP3, MP4, computer, PC, mobile phone, etc.
Cons
  • There are nuances
