The 424mkIII is TASCAM's finest cassette four track. Its advanced feature set offers something for everyone. The 2 independent auxiliaries mean you can add two separate effects to the same channel... not something many of our competitors can do. The 3 band sweepable mid band EQ gives you the flexibility to focus on the sweet spot of the sound to help give it a little more life. The 4 XLR mic preamps keep your inputs quieter, and will save you from the hassles of finding the XLR to 1/4" transformers. The expert will appreciate these advanced features. The novice can grow into them, and improve their skills with time.
