MakerHawk Mini Amplifier Board Bluetooth Amplifier 2.0 2X50W 5V-24V Audio Power Amplifier Module for Store Home Theater Speakers

Very large sound from a small board. Almost lossless distortion. I had another set up on the bench for an mini in-dash BT/FM/Aux receiver/amplifier, so I just needed to swap in the speaker leads and the power supply. Used my variable voltage supply at 12V-2A. Connected to a pair of 3" full range (60-20k), 90 db sensitivity, 4 ohm speakers, 40W (specs call for 50-100W input). No noise issues at all (others that reported this likely misconnected the amp/speakers). Bluetooth sourced from my Fire tablet, found the device in seconds. Volume set on max on tablet, then tried various volume levels on the amp, including full out on Classic Metal on Slacker (I know, LiveXLive), no distortion discernable. Speaker specs recommend a passive radiator for improved bass, this was just a free air test. Played on Piano Jazz on Slacker, awesome sound. I really like the switched pot they used for volume - simply on-off and volume operation. Only thing I saw on initial test was the volume seemed to go out well before Off position, likely due to the pot value used, I'd give it a 4.5 for that....otherwise a 5 overall. I have a few 24V power and torroidal transformaers I may try for a permanent power source. This may end up a desktop or portable bluetooth speaker

Se ve de buen material, falta utilizarlo

Buen rendimiento y cumple con las espectativas.

It worked right out of the box. Sounds good. Plenty of volume for indoor use. I like that they included a power plug with plain cut wires on the other end, in case your power supply doesn't happen to have the right kind of plug.

This thing is so cool , it's very small, I like that it has a power light. You can use it on a car or in the house. I wish I had this thing 5 years ago before I had gotten rid of all my old speakers. Links up with your phone fast and easy.
