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

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…

I have never laughed so much while working on a project. I bought this to turn a set of old Magnavox stereo speakers into bluetooth speakers. Little did I know that when the amp is plugged in or unplugged, a heavily accented Asian woman SHOUTS that the device is ready to pair or paired successfully. is. I needed a decent output volume range from the amp so I set the amp volume to maximum so I could control a wide range from my phone. BUT the female voice is now at least 150 dB louder (much more

After putting 2V at 5A on this little board I got nothing but pure power and fantastic sound from both channels. The small thermal synchronization that is included works great and hardly gets warm even at high volumes. The Bluetooth aspect works very well, the Bluetooth broadcast ID is "XY_BT" and all you have to do is plug in your cell phone or iPad and play music. In my implementation I connected an Alexa Dot Echo and it works great. In terms of sound, the dynamic range is very low, low…

Yes, everything they say is true. Well done, sounds good. Clear plastic panels give it a cute aki swag look. It's lightweight, so if you use thick speaker wire it's prone to flipping over like an astronaut trapped in the tentacles of a space octopus. You can always put a stone on it. Almost all Chinese outfits use the same design and chips, these chips are good, so paying more doesn't mean buying more. You're running the same Class D (or "T") circuitry in a prettier box that just gets more…

From an audiophile point of view. This is my first experience with digital amplification and this product made me buy it. *This overview can serve as a technical specification and operating instructions* Assembly: The electronic board is packed in an anti-static electronics bag. The heatsink is not attached, but you glue it to the amplifier chip already on the underside of the heatsink with the supplied adhesive. The Plexiglas is protected by a removable adhesive paper. In general, assembly is…

I am very impressed with this little amp. The first thing I check on any "cheap" electronics is the solder joints. Budget boards have badly routed cold junctions, cracked solder joints, half knocked out SMT resistors, etc. 99.9999% of the time. This board is assembled with INCREDIBLE quality. All pads have nice shiny solder joints, everything is assembled with precision and the board is a nice thick multilayer board. No cold joints, no lumps, no accidental bridges. The board assembly is in no…
