Review on 🔊 Nobsound 100W Full-Frequency Mono Channel Digital Power Amplifier Audio Mini Amp for Home Speaker, Including Power Supply (Black) by Victor Rodriguez

#1) The 19V power adapter that comes with this unit is not enough for the advertised 100W. You will need a 24V power supply, but you won't find this in the documentation until you've purchased the product. I would recommend that you buy the model without the power supply (is a few bucks cheaper) and then buy the 24v power supply itself. . I had NOT connected any speakers yet, but I could hear sound coming out of the box. There are no speakers in this box. I don't know what is creating this muffled sound, but I don't feel comfortable going forward with it. I really wanted it to be great. I have made. I don't know why it's so hard to find a good full range mono amp.
