For pro tools sessions at 44 and 48 khz up to 64 channels of madi optical i o are available through each set of inputs optical or coaxial at higher sample rates both sets can be used to achieve up to 64 channels of madi optical or coaxial i o as shown in the table below 12
Hd madi back panel 12
Hd madi has the following back panel features 12
Hd madi inputs can stream in at any sample rate and be converted to the current pro tools session sample rate using hardware based real time sample rate conversion src src is also supported on output 12
Hd madi provides 2 sets of madi coaxial in and out ports using high quality coaxial cable connect these ports to the corresponding madi coaxial inputs and outputs of madi compatible audio equipment such as routers digital mixing consoles and converters 12

Connect the loop sync out of each interface to the loop sync in of the next interface with the bnc cables included in your audio interface 16
Connect the loop sync out of the last inter face to the loop sync in of the primary interface or sync peripheral 16
Connecting loop sync 16
If you are using two or more pro tools audio interfaces or a sync peripheral loop sync must be connected to maintain proper clock synchro nization among the devices for an example of connecting multiple pro tools hd audio inter faces see figure 2 below 16
Pro tools hd audio interfaces need room at their sides to maintain proper air flow for cooling do not block the sides of the unit or disconnect the internal fan if the units are rack mounted in a case remove the case lids or doors before operating the system failure to do so can result in the units over heating very quickly which can perma nently damage sensitive components 16
