PylePro 19-inch Rack 4-channel Mixer with Digital Sampler (Refurbished)

As a mixer, this product does the job. it has 8 inputs, 4 can be switched on at a time. Crossfader works well, Left and right channel equalizers works well. The way the mic input is set up is nice, and the blue led lights look nice.HOWEVER, the sampler feature is COMPLETE GARBAGE. There is a loud blip sound at the end of samples, which sounds terrible when you loop the sample. But don't worry because you wont want to loop any samples. why? because there is a delay of about 60 milliseconds from when you press the record button to when the sampler actually begins recording. So basically no matter how hard you try, its impossible to get your samples to play in a loop without there being a ms gap in the beginning or at the end of your sample. So now you've got a loop playing that makes a loud ugly sound every time it loops and its not even in time! Want to try to loop something then match it to something else you've recorded at the same bpm? NOT GONNA HAPPEN. You might get one or 2 measures in time and then it falls out of sync due to the ms gap.Terrible as a sampler.
