Avid Technology HD Native - HD MADI Digital Audio Interface

HD Native Installation Guide8
Synchronization
• Loop Sync input and output for connecting
additional Avid HD audio interfaces and
peripherals
•External Clock input and output for
synchronizing HD I/O with external Word
Clock devices
Expandability
• Optional addition of I/O cards to expand
analog or digital I/O
• Simultaneous use of multiple Avid HD audio
interfaces to further expand system input and
output (for more information see the
Expanded Systems Guide)
HD MADI Digital Audio Interface
HD MADI is a 64-channel, digital audio
interface designed for use with HD Native
systems. HD MADI supports the Multichannel
Audio Digital Interface (MADI) format and
sample rates of up to 192 kHz. HD MADI
provides simplified connectivity between your
HD Native system and MADI-compatible audio
equipment, such as routers, digital mixing
consoles, and converters.

HD MADI Features
• 2 MADI Optical and Coaxial inputs and 2
MADI Optical and Coaxial outputs for up to 64
discrete channels of digital input and output
(32 channels per DigiLink Mini port)
• Supports sample rates of 44.1 kHz, 48 kHz,
88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz
• 24- or 16-bit resolution
• Sample Rate Conversion (SRC) on input or
output
• Front panel clock and SRC indicators
• Front panel signal present LEDs for input and
output
• BNC Word Clock I/O for synchronizing HD
MADI with external 1x Word Clock
•BNC Loop Sync I/O for synchronizing HD
MADI with additional Avid HD audio
interfaces and peripherals (such as HD I/O,
HD OMNI, or SYNC HD)
• Dedicated BNC Word Clock input and XLR
AES/EBU input (clock input only) for external
MADI synchronization (when using SRC on
output)
• Clock support for the following formats:
Internal, Loop Sync, Word Clock, AES/EBU,
and MADI
• Varispeed modes (supports both 64- and 56-
channel standards)
For more information about HD MADI, see
the HD MADI Guide.
To use the full channel capacity of
HD MADI, only a single HD MADI can be
connected to an HD Native card using two
DigiLink Mini cables. No additional I/O
may be used with this configuration.
