The CD-RW750 is TASCAM's budget-minded CD recorder, but features came first when the product was designed. Like most products in this price range, the CD-RW700 offers unbalanced I/O, and S/PDIF digital I/O in coax and optical format. However, this product stands above the crowd, with a RAM buffer, 24-bit A/D and D/A converters for premium sound quality, digital gain adjustment, and digital processing of fade in and fade out from 3 to 30 seconds. It's also got a monitor function that allows it to be used as an A/D converter or sample rate converter, without the need to place a recordable disk in the tray or enter record mode. And of course, it's the only one in its class that will rack mount with the rest of your gear.
