This is only a few days I have done had the stuff. I did not buy new so I had the very good price. It's a really nice stuff unless you have no manual. For the user manual just take on the tascam site just above the model da-40 is about the same. I have not had time to test everything because I finished all the branches on the drive. Home the DA30 is connected to the PC via a digital interface and for the moment it works perfectly I not regret the investment. The only remark is that no manual is relatively complicated to retouve. I recommend it, very good stuff.
