sample Rates
The scaling factor and the sample rate are indicated by three LEDs.
2 fs lEd (yellow): indicates scaling
factor of operation
LED ON = Scaling factor of
sample rate set to 2 FS
LED heartbeat = A 96k Frame signal
is detected at the MADI input which
forces to 2 FS temporarily.
48k lEd (green): indicates the use of
48 khz as base sample rate.
LED ON = Base sample rate set to 48 kHz
44.1k lEd (green): indicates the use of
44.1 khz as base sample rate.
LED ON = Base sample rate set to 44.1 kHz
With the clock set to internal (INT) the sample rate can be adjusted
in the menu. All other clock sources (word clock, MADI) defi ne the
base rate automatically.
The scaling factor of the sample rate has to be defi ned manually
when the clock source is set to internal or word clock.
When a MADI signal is used as clock source, the device will switch
to 2 FS operation automatically when a 96k Frame signal has been
detected. With 48k Frame signals no distinction is possible between
1 FS and 2 FS - so the scaling factor has to be set manually.
Settings depending on clock source:
Clock source base rate set scaling factor set
int manually manually
wCK automatically manually
MAdi automatically manually*
*) A 96k Frame signal will force scaling factor to 2 FS temporarily.
If the clock source is set to word clock or MADI input no adjustment
of the base rate is possible - the measured frequency of the clock
source is indicated then.
