Review on 🔊 Powerful Wireless Bluetooth PA Amplifier - 500W Compact Mini Digital Sound System with 70V/100V Output, Mic Input, Radio, USB - Pyle PMSA126BU by Steph Washington

I needed a commercial room amplifier with 6 ceiling speakers and it worked great. There are sockets on the back for different configurations and I only used 70V so I can't comment on the rest. 70 volt mono ceiling speakers will never sound as good as a good stereo system. You lose some sound quality in exchange for being able to connect multiple speakers together over long distances. I mention this because if I didn't know, I would blame the amp. I like the controls that allow you to adjust the volume, treble and bass. (Reduce bass level by 70V for better quality). We've had it running 24 hours a day, 7 days a week for over 5 months and it's never had any hiccups. The bluetooth receiver we connected is a different story.
