Avid Technology HD Native - HD I;O Audio Interface

Chapter 2: HD Native Hardware Overview 7
Monitoring
• An additional stereo “CUE” output path in
Pro Tools for headphone monitoring from the
front panel headphone jack
• Front panel Control Room (MAIN/ALT) and
Headphone monitoring volume control
• Flexible monitoring with fold-down from all
stereo and surround formats (up to 7.1
surround)
• Input mixer for low latency direct monitoring
of a variety of incoming signals (configured in
the Pro Tools Hardware Setup)
Synchronization
• Loop Sync input and output for connecting
additional Avid HD audio interfaces and
peripherals
• External Clock input and output for
synchronizing HD OMNI with external Word
Clock devices
HD I/O Audio Interface
HD I/O is a multichannel digital audio interface
designed for use with HD Native systems.
HD I/O features extremely high quality 24-bit
analog-to-digital (A/D) and digital-to-analog
(D/A) converters, and supports sample rates of
up to 192 kHz.
HD I/O comes in three standard configurations:
• 8 x 8 x 8 (8 analog in, 8 analog out, and 8
digital in and out)
• 16 x 16 analog in and out
• 16 x 16 digital in and out
You can also add or remove HD I/O Analog
Expansion cards (ADC and DAC) and HD I/O
Digital Expansion cards for custom
configurations.
HD I/O Features
HD I/O provides up to 16 discrete channels of
Pro Tools input and output, with 4-segment
LED meters for input and output.
Analog I/O
• Up to 16 channels of 24-bit D/A and A/D
converters for superior analog input and
output at sample rates of 44.1 kHz, 48 kHz,
88.2 kHz, 96 kHz, 176.4 kHz, and 192 kHz
with Analog In and Analog Out HD I/O cards
• Soft Clip and Curv limiting circuits to protect
against clipping on analog input
Digital I/O
• Up to 16 channels of 24-bit digital I/O, using
AES/EBU, TDIF DB-25, or Optical at sample
rates of 44.1 kHz, 48 kHz, 88.2 kHz, 96 kHz,
176.4 kHz, and 192 kHz with a Digital HD I/O
card
• Real-time sample rate conversion on digital
inputs with a Digital I/O card (up to 16
channels of AES/EBU, Optical, or TDIF)
• Support for S/MUX Optical for sample rates of
88.2 kHz and higher
• Support for 2 channels of S/PDIF Optical
(enclosed) with sample rates of up to 96 kHz
• 2 channels of AES/EBU I/O (enclosed) with
support for sample rates up to 192 kHz
• 2 channels of 24-bit-capable S/PDIF I/O
(enclosed) with support for sample rates up to
192 kHz
