The 1600P-DB high speed sewing machine has the DB needle. Like the other 1600 Professional machines, it sews a straight stitch at 1,600 stitches per minute, the fastest on the market. From the new "Liquid Response" foot control to the pre-tension system, everything on this machine is built for high quality stitches at professional speeds. But while it gives you the performance of an industrial machine, it also gives you the quiet operation and sleek design of a Janome.
