SYNC
WCK
LED - indicates selected clock source and the
lock state of the WCK input.
(OFF) = no signal lock
(100 % purple) = signal lock, selected clock source
Device sample
rate
Displays current clock master and measured sample
frequency.
Clock master Pull-down menu - selection of clock source
Values:
PTP = PTP clock (Master or Slave)
SFP = MADI SFP input
BNC = MADI BNC input
SC = MADI SC input
INT 44.1 = internal clock generator 44.1 kHz
INT 48 = internal clock generator 48 kHz
WCK* = Word Clock @ MADI BNC input
Sample rate Pulldown menu to adjust sample rate
Values: 44.1 / 48 / 88.2 / 96 / 176.4 / 192 kHz
FastSRC (NET) Pull-down menu - enabling / disabling of Sample
Rate Conversion at RAVENNA I/O **
OFF = SRC not active
ON = SRC active
PTP state State of PTP (Master / Slave).
PTP jitter PTP-clock jitter per second
PTP offset Offet relative to PTP-clock master
RTP state Status of packet processing (OK, Error***)
Audio engine
RX state
State of module’s audio engine - receiving
(ON) = ok, receiving data
(blinking) = not all received packets can be processed
Audio engine
TX state
State of module’s audio engine - sending
(ON) = ok, sending data
(blinking) = not all packets can be sent to the network
* Selecting WCK as clock source will change the operating mode of the MADI
BNC input, accepting a word clock signal according to AES11 there.
** See „Sample Rate Conversion“ on page 26.
*** Error: packet time stamps are out of bounds.
Possible reasons: stream offset may be too small or transmitter or receiver
are not synced properly to the Grandmaster.
