    Default Yamaha Aventage RX-A1050 and 4 ohms speakers

    werthliving.com

    Hi there guys, hope you can help. I bought Pioneer Elite Atmos 5.1 speaker system, which are all 4 ohms.
    I was very interested in using them with that Yamaha receiver, but I'm not sure if it supports the entire speaker system. The user guide says you can switch it to 4 ohms and use front speakers. But what about the rest?

    Any chance you could clarify things out for me. I would really appreciate it.

    Hard to know for absolute sure, but you're probably fine. The 6-ohm setting on the impedance switch lowers the maximum voltage the amplifiers can put out, which also reduces the current that will be drawn, so as to protect the output transistors. In movie soundtracks, the channel carrying the most energy typically is the center, followed by the front left and right, and then considerably less to the surrounds. So the amplifiers feeding the surround speakers tend to be less taxed than the ones feeding the front speakers. I also notice that Yamaha specs at least dynamic power into 2 ohms, which would suggest adequate current capability.
