Outputting a copy-protected digital audio signal
You can set the copy-protect flag of the digital audio signal that is output by the
MV-8000. If this signal is recorded onto a digitally-connected MD recorder etc., further
digital copying from the recorded media will not be possible.
1.
Access the GLOBAL screen as described in Accessing the Global screen
(p. 178).
2.
Set the Digital Out Copy Protect parameter.
If this is On, the copy-protect flag will be set for the digital audio that is output.
Specifying the word clock master for an R-BUS connection
You can specify whether the word clock (the synchronization signal for transferring
digital audio data) master device will be the externally-connected R-BUS device or the
MV-8000 itself.
1.
Access the GLOBAL screen as described in Accessing the Global screen
(p. 178).
2.
Set the R-BUS Word Clock parameter.
Normally you will leave this set to “External.”
Value
External
Word clock will be received from the externally-connected R-BUS
device. In this case, the sampling frequency of the signal sent from
the R-BUS connector of the MV8-OP1 will be the same as the sam-
pling frequency of the external R-BUS device.
The signal sent from the MV-8000's DIGITAL OUT and the internal
processing (for sampling, etc.) will always be 44.1 kHz.
Internal
Word clock (44.1 kHz) will be generated within the MV-8000 and sent
via the R-BUS connector. Set the externally-connected R-BUS device
to function as a Slave.
About word clock and digital connections
Normally, the word clock is internally generated and output by the device (master)
that transmits the digital audio signal. The receiving device (slave) will receive this
word clock and synchronize to it. This means that the sampling frequencies will
normally be identical. However for some devices, the sampling frequencies of the
data being transferred may actually differ.
The digital circuitry of the MV8-OP1 (sold separately) installed in the MV-8000
contains a sampling rate converter. This means that a digital signal can be received
regardless of the incoming sampling frequency. The digital signal sent via R-BUS
will be the same as the sampling rate that is received.
Also, there may be cases in which the connected R-BUS device
• Cannot generate a word clock (i.e., will function only as a slave), or
• Must be set to receive word clock (slave) because of how your system is
connected.
In such cases, you can use the “Internal” setting so that the MV-8000 is the word
clock master. However, the digital signal sent via R-BUS will be fixed at a sampling
frequency of 44.1 kHz.
