Question: Can you record cassettes, or just play them?
Document: I bought this device to replace my ancient shelf system because it would allow me to convert my old vinyl and cassettes to digital format. The process is a bit clumsy and may be a challenge for those not comfortable with technology. You first set the selector to the appropriate source (phono or cassette), connect a USB flash drive, start the play, and press the REC button.
The cassette player ate two my cassettes. The discription of recording from vinal did not include that you can only record to a 2GB sd card. Really not enough room for an entire album.I was very disappointed with this product and supprised that Amazon would sell  this something of such poor quality.
The double decks play fine, until they EAT YOUR TAPES. I've tried three cassettes, and both decks have gotten some of the tape stuck in them. I even had to splice one of my favorite rare ones because of it. VERY DISAPPOINTED. STAY AWAY.Recording Function: Great - This works well. It's nice to have your vinyl on MP3s so easily. It works with CD, Cassette (but don't do it..), Vinyl, but not radio, which isn't a problem for me.
I was so excited about getting this little stereo set. I'm a vinyl noob, so I was happy I found this nice all in one set. I'll review each function of the set.Turntable: Great - Turntable works flawlessly (so far..). You can play any size record on speeds 33, 45 and 78. I've tried out all my records and they play fine.CD: Horrible - CDs play fine, put the system seems to have trouble reading the discs sometimes.
Easy to set up, been playing mostly cassettes on it, have lots, enjoy the stereo, having it setting on table besides my desk in my office, use it practically every day. Very happy with it. Want to do some dubbing music and make tapes of my favorites on the dual cassette desk, real reason why I purchased unit.
This overpriced piece of crap. Designed and Built as poorly as possible1. Doors on cassettes have no windows in them to see how much tape is left,or if the tape is still moving. (which because these doors are so flimsy the tape does not move but gets ate up by the unit). The most lowest price units have at least  a sight window(s).2. The turntable is poorly designed too. No lift arm to place tone arm.
I like to crank some songs up LOUD and cant do it with this. So I will copy my favorite tracks from my old LPs and play in the car.
I am loving my new turntable not only does it let me play my vinyl records but lets me transfer them into mp3 format. Can't wait to start transferring my music.
But if you are like me and simply want to play vinyl, tapes, CDs, radio, USB/MP3 with recording all in the kitchen - you will certainly enjoy the convenience. It's a conversation piece.
great unit. just what I wanted and more, can even play my old records. everything works perfectly. I'm using it with my old big speakers -- sounds great. plus fast shipping.I'm very pleased.
Answer: You can record on cassette from almost any input. I recommend getting the manual and reading through it here: http://www.pyleaudio.com/sku/PTTCSM60/Turntable-Boombox-Multimedia-System---Plays-AMFM-Radio,-CDs,-Cassettes,-MP3s,---USBSD-Memory-Ports-and-Vinyl-to-MP3-EncodingIt isn't written very well, but it outline all features in detail.
