Walkman or Boombox? High end cassette recorder? That is Both those things in TC-D5.
It is a total of four models:
TC-D5 1978 (RCA input)
TC-D5M 1980-2005 (RCA input)
TC-D5 Pro 1982 Professional (XLR Mic input)
TC-D5 Pro II 1986-1999 ($750 1992) Pro 1982 Professional (XLR Mic input)
The D5M features a built-in monitor amplifier with choice of loudspeaker or stereo headphone output, record limiter switch, mic input attenuator, and three-Way power source for professional-grade flexibility in record and playback.
The TC-D5M represents the application of Sony total system technology to the demands of portable stereo cassette recording.
Its innovative design provides steady, stable performance even in rigorous field use.
Yet the D5M shares many features in common with Sony’s home decks, including metal tape capability, FG servo control, and the Sendust and Ferrite head.
Thus, the portable TC-D5M performs on a level comparable to fine home use decks. In fact, when you are not using the D5M in the field, you can connect it to your home high fidelity system with excellent results.
