Review on 🔊 AIYIMA DC12V-24V 2.1 Channel TPA3116 Subwoofer Amplifier Board High Power Bluetooth Audio Amplifier Board 50W+50W+100W (Bluetooth Amp) by Nicholas Erickson

So the main problem with this amp in my application, as in other applications, is that there is no way to switch the standard input to line. Regardless, the default is Bluetooth, and if you're using this amp for an application that uses a line level input by default, there's an extra step involved every time you turn it on. I was planning to use this booster (actually 4 of them) for different slot machines. While it sounds good enough to be the main amp for this app, I won't be using it as it would require opening up the device every time it's powered on and pressing a button to change the input mode. Standard, because otherwise it's a great little amp. 3 stars deducted for lack of functionality. I can think of many applications where Bluetooth isn't the main focus. For example, PC speaker amplifier, gaming machine, TV speaker, virtual pinball machine, radio, etc.
