Blackmore BTU-5008-B
A Battery-Powered Portable, Versatile PA Speaker
Featuring an 8" woofer, a 1.5" tweeter and 1000W (P.M.P.O) power handling, this PA system delivers dynamic, full-range sound from a robust, all-in-one package. It supports Bluetooth streaming + 3.5mm wired audio sources and has a microSD card slot for playback of MP3 files. It boasts dual MP3 players with dual USB inputs as well as a manual crossover and headphone input for live MP3 track mixing. ¼” guitar and mic inputs make this unit capable of addressing or playing for a group. An array of buttons and dials—like EQ presets, treble/bass control and mic volume—let you take full control of mix and music playback. To top it all off, a heavy-duty nylon strap makes this speaker easy to carry around.
Pros: Good sound, lots of input options, plays .mp3 files directly off USB drive.
Cons: .mp3 players extremely limited functionality. Can only play files off root drive, no folders. Almost zero documentation.
Overall Review: [EDIT] I seemed to had lost USB MP3 functionality but it may have been the files on the USB drive that was the issue. For a while neither the A or B would work but now they are. Currently everything it working as it was originally, and am as happy with the product now as I was then. Only had about a week, took camping, solid sound, nice carry, decent bass but less so the farther away you get, which is normal. Battery played over 6 hours after first charge. Purchased mainly for the .mp3 USB functionality, but again extremely limited. The only documentation in the package was a one page to scan with a smartphone to download manual. Went to web site, manual three pages long, very limited, larger manual coming soon. It came later, it is lacking to say the least but better than it was. In the short time I have had it though, if the features fit you, I would recommend the product.
