The LXMADI control panel window is displayed during the
driver installation process so that you can configure its
parameters.
Clock settings
● Sample rate
Sampling frequency value of the internal clock. In case
the clock source is MADI or WordClock, make sure the
selected frequency value matches the frequency of the
external clock (see section Input Status)
● Clock source: Sampling clock can be generated
internally (Internal), or can be the MADI input (MADI
in), or the Word Clock input (Word Clock in).
● Word Clock out
This parameter is accessible only if Clock Source is not
set to "Word Clock in".
Check this option so that the card outputs a Word
Clock signal that is generated from the selected clock
source (except Word Clock in).
Options
● Channel Mode: channel mode of the MADI output.
64 / 32 channels (at 44.1 & 48 kHz / 88.2 & 96 kHz)
32 / 28 channels (at 44.1 & 48 kHz / 88.2 & 96 kHz)
Note that LXMADI always receives 64 (or 32)
channels even in 56 (28) channels mode.
● Frame rate
Frame rate of MADI receiver and transmitter. Nominal
Sample Rate: 1 frame = 1 channel (64 channels at 48
kHz, and 32 channels at 96 kHz).
Half Sample Rate: Allows transporting 96 kHz in 48
kHz frames (1 frame = 2 channels).
Input Status
This section displays information reported from the card.
● Current clock: displays the current clock source and its
frequency.
● MADI Frame rate: returns the frame rate detected on
the MADI input, and if the MADI optical signal is
received correctly (Locked) or not (Unlocked).
Current clock frequency and MADI frame rate can be
different. Foir instance the requested clock can be 96
000Hz, and the MADI frame rate can be 48 000Hz (2
channels per frame).
● Word Clock: displays the detected frequency on the
word clock input.
Note: parameters displayed in red mean there is a
mismatch between the requested clock value and the
detected value, or if the card does not receive the MADI
signal.
Click on "OK" to confirm the parameters.
