This is my video review of the Dayton Audio KABM 215 and 30M -- two very affordable Bluetooth amplifier boards from Dayton Audio.
✅ PROS: Cheap, good sound, DSP/equalizer support, DIY Friendly
⚠️ CONS: Get hot, weird volume control, high idle power use, not as powerful as they say

Update from Parts Express: "the amplifier chip has a built-in protection mechanism that activates at a high temperature of 160°C. The recommended ambient operating temperature range is from 40 to 85°C, while the junction (chip) temperature should ideally stay within 40 to 125°C under normal operation."

Excellent video. Would love to see what youd recomend for a cassette player upgrade to bluetooth or wifi service.

@LeftyMaker Ай бұрын

Does it have any audio input connectors? If so, it is best to use some sort of an external module.

@@LeftyMaker I totally agree. It seemed during the late 80-90s they loved to sell cassette and CD players without AUX In connectors.

I swear, that "module" at 7:55 is just a dismantled car radio, lol

I once saw a similar module on one of those battery-powered ride-on kids cars. Not sure if it was like that when new or some crafty dad added it afterward.
