Using the dCS 974 to monitor a track
If you just want to use the dCS 974 as a level monitoring device, you can control
the bandwidth you monitor by setting the output data rate – 44.1kS/s will give
approximately 20kHz bandwidth, whereas 96kS/s will give approximately 40
kHz bandwidth.
the bandwidth you monitor by setting the output data rate – 44.1kS/s will give
approximately 20kHz bandwidth, whereas 96kS/s will give approximately 40
kHz bandwidth.
The meters can be used to monitor DSD by setting a DSD to PCM conversion,
and using the appropriate output data rate.
and using the appropriate output data rate.
Watch Out for this One!
If the unit is tested with sine waves at frequencies which divide almost exactly
into the sample rate (e.g. 6.001kHz signal, 48 kS/s sampling frequency), the
segments on the right hand side of the meter will flicker. This effect disappears
if the signal frequency is changed by about 10Hz and so it is not a problem
when monitoring music. It is caused by the signal beating with the sample rate.
