Nice amp, with 4 speakers output. Also has sd card reader and usb for mp3, 3.5 mm, rca audio and bluetooth. Audio via aux is a bit soft, but other sources are great. It also has a little LCD where it shows the mode is running on.
This little Tuner/Receiver totally exceeded my expectations. The FM tuner auto searches and registers up to 20 stations. The SD Card, USB, RCA in and Bluetooth work flawlessly! I am using it to power 4 all weather speakers in a 7M x 7M outdoor seating area. Volume is excellent and distortion free. Unit has cooling fins but so far it has not even become warm. If you have any orphaned speakers that need power this is a great choice!
