DAT Deck The Panasonic SV-3700 enjoyed a great reputation for its extreme reliability in pro settings and for its exceptional warm sounding analog-digital conversion circuit (the DAC stage alone is more than worth the asking price). It is simply a great machine for moving analog music source recordings over to digital formats. Specifications include frequency response of 10-22,000kHz with greater than 92 decibel signal to noise ratio, total harmonic distortion of less than 0.05%, and wow and flutter so low it is not measurable.
