I PCM (Linear PCM) Linear PCM is a signal format under which an analog audio signal is digitized, recorded and transmitted without using any compression.

S VIDEO signal
With S VIDEO signal system, the video signal normally
transmitted using a pin cable is separated and transmitted as
the Y signal for the luminance and the C signal for the
chrominance through the S VIDEO cable. Using the S
VIDEO jack eliminates video signal transmission loss and
allows recording and playback of even more beautiful
images.

PCM (Linear PCM)
Linear PCM is a signal format under which an analog audio
signal is digitized, recorded and transmitted without using
any compression. This is used as a method of recording CDs
and DVD audio. The PCM system uses a technique for
sampling the size of the analog signal per very small unit of
time. Standing for
“
pulse code modulation
”
, the analog
signal is encoded as pulses and then modulated for
recording.
■
Sampling frequency and number of
quantized bits
When digitizing an analog audio signal, the number of times
the signal is sampled per second is called the sampling
frequency, while the degree of fineness when converting the
sound level into a numeric value is called the number of
quantized bits.
The range of rates that can be played back is determined
based on the sampling rate, while the dynamic range
representing the sound level difference is determined by the
number of quantized bits. In principle, the higher the
sampling frequency, the wider the range of frequencies that
can be played back, and the higher the number of quantized
bits, the more finely the sound level can be reproduced.
■
I/O ASSIGN (SET MENU)
Although component is normally connected according to
jack names shown on the rear panel, this unit includes a
function that assigns jacks according to the component
being connected. If the component being used differs from
the component name shown for this unit
’
s digital jacks, it is
possible to assign jacks according to the component being
connected. This makes it possible to change the jack
assignment and effectively connect more component.
