Review on 🔵 DROK Blue~Tooth Amplifier Board 4.1 | Digital 2 Channel 50W+50W | Wire~Less BT 3.0 4.0 | Speaker Amp with Case by Derek Dolla

I bought this amp specifically for my home gaming machine that has a 3.5mm audio input. In my case, the amp turns on and off along with the rest of the electronics in my arcade. Unfortunately, although the 3.5mm audio source remains connected to the amplifier at all times and the amplifier remembers what volume it was last set to when powered on, it does NOT remember that it was set to input 3.5mm AUX and defaulted back to Bluetooth mode. While unplugging the 3.5mm and plugging it back in automatically switches the input source to AUX (is it really considered automatic then?), this scenario is unrealistic for my use case and requires me to ONLY have an advanced button for switching connect input mode every time i turn on my car for the first time. Unfortunately, while this amp is very clean and crisp with no hiss or hum and is VERY powerful for its size (hence my very high rating), I have a hard time recommending it to anyone looking for a cheap, powerful amp that has bluetooth functionality considered to be a secondary or unnecessary function. Unfortunately, the truth is that the aux input was 'additional' or 'retroactive' if you will, and Bluetooth connectivity is all this amp was really designed for.
