A
CHANNEL STATUS MONITOR
Here you can monitor the status of the digital sig-
nals that are input from the DIGITAL STEREO IN
connector and from a digital I/O card installed in
OPTION I/O. Each display item has the following
significance.
• Fs (frequency)
Indicates the sampling frequency of the input sig-
nal.

Sampling frequency = 44.1 kHz

Unknown sampling frequency
No signal is being input, or an
UNLOCK
invalid signal is being input
• EMPHASIS
This shows whether the input signal has been pro-
cessed by emphasis.

digital input signal.

Tip!
• Processing that pre-emphasizes the high-frequency
portion of the signal is called "emphasis," and pro-
cessing that attenuates this portion to restore the
original flat response is called "de-emphasis." Even if
the AW2816 receives a signal to which emphasis has
been applied, it will not perform de-emphasis.
• Digital input signals from option I/O are displayed in
pairs of adjacent odd-numbered
input channels (channels 1/2, 3/4, ...)
Meaning
even-numbered
