I use this machine to scan my old 78s, previously recorded on K7 and also older K7 recorded the commrce. Great, but after some trial and error because the manual is a bit simplistic. To remember that there's interest to uncheck the "Automatically separate recording tracks" to avoid being cheated by more or less long silences in the music. The "Audacity" is more complex but I do not despair of the master shortly. Considering the price and quality of the product, I do not regette my acquisition. 2 batteries must be added for use as player ... relief.
