Review on 🔊 50W Compact Mini Public Address Amplifier - Home Power Audio Sound PA Receiver System with AUX, 2 Microphone Inputs, Independent Volume Control - Pyle PMSA20 Black, for 4 to 8ohm Speakers by Rick Kreutzer

This device would be perfect for my application. This is a small digital amplifier. However, these are not 50W RMS. With ideal load it is actually 8-10 watts. Would still satisfy my need. Sounds fine. The problem is that it generates almost as much RF energy as it makes noise. It solid 950kHz. from the speaker jacks even into an 8 ohm load. This radio signal is modulated in amplitude by any audio input. If I have an antenna connected to the speaker jacks, it could be a nearby transmitter. There is no FCC approval label on the device or in the manual. I suspect it's illegal to sell in the United States.
