INPUT STATUS A-D
The INPUT STATUS display provides information about input signals received by the
AE-7000’s A/D input converters. There are four kinds of information displayed
regarding each of the four inputs, A, B, C and D. The displayed information is explained
in the following sections.
TYPE
Shows the format of the received digital audio:
TYPE1
—is AES/EBU-format digital audio.
TYPE2
—is S/P DIF-format digital audio.
“--”
—means that there’s no input signal.
COPY PROTECT
COPY PROTECT reveals the presence of SCMS copy-protection in the input signal.
On
—means that SCMS copy-protection data is present in the input signal.
Off
—means that no SCMS copy-protection data is present in the input signal.
“--”
—means that there’s no input signal.
EMPHASIS
Emphasis boosts the high-frequency content of digital audio signals. If EMPHASIS is:
On
—emphasis signals are present in the digital audio.
Off
—there’s no emphasis applied to the digital audio.
“--”
—means that there’s no input signal.
SAMPLING FREQ
SAMPLING FREQ shows the sample rate of the received digital audio, from 32k to 48k.
“Unlock” is displayed if:
there’s no signal. there’s no master clock
the signals are outside the supported sample frequency range.
CLOCK SOURCE
CLOCK SOURCE selects the master clock timing reference for the AE-7000. This
parameter interacts with the VS-2480’s MASTER CLOCK parameter (Page 132).
When the VS-2480’s MASTER CLOCK parameter’s value is the R-BUS jack to
which the AE-7000 is connected, the AE-7000’s CLOCK SOURCE should be set to
INPUT A or WORD CLOCK.
When VS-2480 MASTER CLOCK is set to INT, COAXIAL IN, OPTICAL IN, WORD
CLOCK or EXT TIME CODE, the AE-7000’s CLOCK SOURCE should be set to
R-BUS. However, if a separate word clock generator is supplying word clock
directly to the AE-7000, set the AE-7000’s CLOCK SOURCE to WORD CLOCK.
The following table explains the CLOCK SOURCE values and tells you how to set the
VS-2480’s MASTER CLOCK parameter with each AE-7000 CLOCK SOURCE value.
Turn down the volume for all connected equipment before changing the CLOCK
SOURCE value to avoid damage to your equipment.
