| HDX, Pro Tools
®
| HD Native, and
Pro Tools
®
| HD systems. HD I/O features 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 dig-
ital in and out)
• 16 x 16 analog in and out
• 16 x 16 digital in and out
You can also add or remove analog (ADC and
DAC) and digital cards for custom configurations.
Pro Tools | HD I/O Features
HD I/O provides up to sixteen discrete channels of
audio input and output, each with a four-segment
LED meter. The total available analog and digital
I/O is dependent on the configuration of Analog
and Digital Expansion I/O cards installed in
HD I/O.
