The Pyle PT659DU Dual Cassette Deck is a device that features two cassette players to allow you to copy the contents of one cassette to another cassette. This deck also lets you copy and transfer the contents of your cassettes into MP3 files thanks to its converter function, the free Audacity software included and a USB connection to your computer. 

Cassette-to-cassette duplication can be performed at normal or high speeds, while a dynamic noise cancellation mode reduces background noise and sound artifacts for optimal audio quality. This cassette player is equipped with a switch to choose between standard type I cassettes and chromium dioxide (CrO2) type II tapes. 

RCA line-in and line-out connectors allow the cassette deck to be connected to stereo systems and used as a standalone player. Additionally, a USB port on the back of the device allows you to connect it to your Mac or Windows computer to convert to MP3.
