Review on Nobsound Bluetooth Amplifier Audio Speakers Home Audio by Michelle Dreger

I used this to start with when disassembling and reassembling a Polk soundbar as it would not turn on until unplugged and plugged back in. on the outside of the mdf case i mostly connected 7 speakers and didn't have a frequency splitter for high, mid or low frequencies but connected all three, 2ch connection is probably not recommended and aux to tv is not the best sound quality. But I use it every day and for the price I've brought my soundbar and subwoofer back to life. TV volume with remote control and/or via Bluetooth. I am very satisfied with this product. I've used it in many different projects including portable speakers and home theater. If I had to upgrade, I'd like to find one with a dedicated bass channel and an optical sound option for better sound quality. The rest are very satisfied.
