Technics PCM AD/DA Converter
Not sold (around 1979)
Commentary
A PCM AD/DA converter that converts an audio signal into a digital signal of the Electronic Industries Association of Japan standard and vice versa.
It was exhibited at the 1979 Audio Fair as a reference for technological development.
It is used as an AD converter when an audio signal such as a microphone is connected to the input of a PCM digital mixer.
It is also used as a DA converter to convert digital signals that have been mixed, edited, or otherwise processed into audio signals.
The SH-P1 performs AD/DA conversion by curvilinear quantization, but this AD/DA converter performs 14-bit linear quantization conversion, so the effective SN ratio can be improved.
