After 2 months of research and thought. I love my purchase. Such an ease when it comes to recording. Makes it so effortless to transfer audio to computer with hours of recording, just as long as a memory card is added. Four inputs for microphones, four inputs for headphones, aux, and can even record a call or music from a mobile device via audio jack or bluetooth. Levels are all adjustsble and monitored. I love this mixer! A lot of thought and craftsmanship went into this Roadcaster Pro. Great job!
