VENUE MADI Option Card Guide10
3 Go to the System page and, under Inputs 1-48 or
Inputs 49-96, choose either Optical Priority, Optical, or Coaxial
from the Input Format pop-up menu.
4 On the MADI card, the Sig LED and Opt LED indicate signal
status as follows:
Sig Lights green when a valid MADI stream is detected on ei-
ther the coaxial input port or the optical input port of your
MADI card.
Opt Lights green when a valid MADI stream is detected on the
optical input of your MADI card, and the Optical input is ac-
tive.
Synchronizing MADI Devices
Any time two digital audio devices are connected together
care must be taken to ensure they are properly synchronized
or the audio will suffer from clicks, pops and distortion (even
if the devices are operating at the same sample rate).
This synchronization can be achieved by using a dedicated
word clock connection between devices, by synchronizing the
receiving device to the incoming MADI audio signal, or by us-
ing onboard Sample Rate Conversion (SRC) on the receiving
device.
This section shows the following three example of configura-
tions using a dedicated word clock connection between de-
vices:
 Using Word Clock to Synchronize Two VENUE Systems
 Using Word Clock to Synchronize a VENUE System and an-
other MADI Device
 Using an External Master Clock to Synchronize Devices
Not all devices support all of these synchronization methods,
so you should consult the user guide for your MADI device in
order to determine its capabilities.
Using Word Clock to Synchronize Two VENUE
Systems
When using MADI to connect two VENUE systems, one of the
systems provides word clock to the other system. The system
receiving word clock detects it automatically.
To synchronize two VENUE systems:
 Connect the coaxial cable from the Word Clock Out port on
one of the VENUE systems to the Word Clock In port on the
other VENUE system. The VENUE system receiving word clock
auto-detects word clock and displays “EXT” in the Mode box
on-screen.
Choosing the MADI card Input Format
When connecting two VENUE systems using MADI, a ded-
icated word clock connection is required.
