Dayton Audio SA230 With Wrong Voltage Set

    If you are working on setting up an awesome home cinema or gaming system, bass shakers are a huge game-changer when it comes to immersion. There is a huge choice of subwoofer amplifiers that you can use to power the bass shakers, one of the more popular being the Dayton Audio SA230.

    The Dayton Audio SA230 is a universal device when it comes to the voltage it can accept. With the US using 110volts and Europe using 220 volts it is important to make sure you check the voltage of the device before plugging it in. Connecting a device that is configured for a 110-volt circuit to a 220-volt outlet can fry the device, rendering it useless.

    During the setup of the Dayton Audio SA230, you will see there is a switch that will allow you to change between 110 volts and 220 volts. While changing this is easy, you will also need to be aware of the fact that you need to also change the fuse. Somehow, I was smart enough to change the fuse but I forgot to change the voltage!

    Powering On Device with Wrong Voltage Set Now It won’t Start

    Having turned on the SA230 amplifier with the voltage switch set to the wrong value, you will find that the device no longer turns on when you change it to the correct value. You will likely have the urge to panic. Your expensive amplifier has just blown from the incorrect voltage but all is not lost.

    You more than likely changed the fuse already, if you check it, it should be blown. Since this is a glass fuse, it is easy to see when the fuse has blown. Depending on where you live, the fuse type and amp rating may differ. For me, It was a 2.5a fuse, which turned out to be a bit of a tricky one to find. Thankfully, they are easily available on Amazon.

    Make 100% sure you have found the correct replacement fuse and insert it into the amplifier. This time, make sure you have also set the voltage switch the correct way and secured it. Once everything looks good, you should be able to try again to power up the device and this time, it should work just fine.

    1. On my Dayton Audio SA230 230W Subwoofer Amplifier the red power light is on but won’t go to blue powering the subwoofer like it use to.

      • Mine is doing the same thing.
        Red light on but won’t go to blue.

    2. Check the fuse. I had the same issue and replaced it. Light is blue again.
