HD MADI has the following front panel features:

• Power Switch and LED Ring - This button turns HD MADI on or off. The LED ring around the power button will light green or orange to indicate the system status (Green and Orange LED ring )
• Sample Rate - These  LED displays the current sample rate of the internal crystal oscillator for MADI: 44.1 kHz, 48 kHz, 96 kHz, 176.4 kHz, or 192 kHz. The sample rate is set when you create a new session and can be changed in the Pro tools hardware set up or playback engine dialogs if no session is open
• Loop Master LED - The LOOP MASTER LED indicates which pro tools audio interface is the master pro tools peripheral. The loop master LED will be continuously lit on the current loop Master peripheral only and unlit on all other peripherals.
• Sync Mode LEDs - The SYNC MODE LEDs indicate the current clock source as set in pro tools. ( Internal, Digital,LOOP,External)
• Sample Rate Convert - HD MADI provides real-time sample rate conversion on input or output. ( Input,Output,AES/EBU & World Clock)
• Signal Present - The signal present LEDs indicate signal for input and output . The top LED indicates input and the bottom LED indicates output ( input & output )

HD MADI has the following Back panel features:

• MADI optical In and Out  - HD MADI provides 2 sets of MADI Optical In and Out ports. Using high-quality optical cable,connect these ports to the corresponding MADI optical inputs and outputs of MADI compatible audio equipment, such as routers, digital mixing consoles and converters
• MADI Coaxial In and Out -  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
• Number of Channels - For Pro Tools sessions at 44.1 and 48 kHz, up to  64 channels of MADI Optical I/O are available  through each set of inputs (Optical or Coaxial).
• Real-Time Sample Rate Conversion - 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.
• Primary DigiLink Mini Ports - HD MADI provides 2 Primary DigiLink Ports. The Primary port is where the DigiLink Mini to  DigiLink cable connects a Pro Tools|HD card to HD MADI. Each Primary port sends and receives up to 32 channels to and from the Pro Tools cards.
• DigiLink Mini and DigiLink Cables - Use DigiLink cables with a DigiLink Mini to DigiLink adapter cable to connect HD MADI to a Pro Tools|HD Accel Core or Accel card.
• DigiLink Mini to DigiLink Adapter Cables - Use DigiLink Mini to DigiLink adapter cables to connect HD MADI to Pro Tools|HD cards.
• SRC AES/EBU - A single female AES/EBU port (clock input only) is provided for synchronizing to an external AES/EBU digital clock source when using MADI Sample Rate Conversion (SRC) on output. This can be configured in the Pro Tools Hardware Setup dialog.
• SRC Word Clock In 1 & 2 - The SRC Word Clock In ports 1 & 2 are standard BNC connector that provides Word Clock input for synchronizing to an external Word Clock digital clock source when using MADI Sample Rate Conversion (SRC) on MADI output. This can be configured in the Pro Tools Hardware Setup dialog
• Word Clock In and Out - The word clock in and out ports are standard BNC connectors that receive and output word clock signal. These ports can be used to synchronize HD MADI with any word clock-capable device.
• Loop Sync In and Out - Loop sync is a dedicated clock loop for synchronizing multiple pro tools peripherals together (such as SYNC HD I/O and  one or more audio interfaces).
• AC power - This connector accepts a standard AC power cable. HD MADI is auto power-selecting (100V to 240V) and will automatically work with a standard modular cable to connect to AC power receptacles in any country.
