In regard to the sampling frequency

Normally, there are the three following types of digital signals, and they are called sampling frequen-
cies. The sampling frequencies are divided as follows according to the type of the digital equipment.
48 kHz :Standard mode for DAT, B-mode transmission of BS tuners, etc.
44.1 kHz :Standard mode for DAT, CD, MD, etc.
32 kHz :Standard and long-time mode for DAT, A-mode transmission of BS tuners, etc.
(DAT: Digital Audio Tapedeck)
As this unit has a built-in sampling rate converter, 48 kHz and 32 kHz digital signals can be recorded
converted to 44.1 kHz.
