Digigram LX-MADI Panduan Pengguna
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.
