PIONEER P-D1 (1982)
|
|
Before the introduction of the CD player all major manufacturers were working on PCM (Pulse Code Modulation) audio players for both disc and compact cassette format. Such a model was the DAD 1516 prototype presented by Pioneer in 1982. This PCM-DAD (Digital Audio Disc) was meant to have 4 channels but the standardization of the Sony-Philips Compact Disc meant that Pioneer had to follow the new standard. As one can see, the P-D1 (the first CD player from Pioneer) kept the original design idea of the prototype with vertical loading disc. Some of the early promotional materials still show a demo disc labelled as DAD (Digital Audio Disc) even though this was a Compact Disc format. The P-D1 features Burr-Brown 16-Bit monolithic DAC and Toshiba OPH-31 laser block. Dimensions: 420x140x330 mm | Weight: 12.1kg | Original sale price: 2500 DM in Germany.
