FEATURES
VX1222HR and VX1221HR are audio cards for PCI bus. They are ‘Universal
PCI 64-bit/66 MHz’, which means they can be plugged in 32-bit/33 MHz 5 V
PCI slots as well as in 64-bit/66 MHz 3.3 V keyed PCI slots. The cards are also
compatible with PCI-X interfaces.
VX1221HR main hardware features
•
1 digital AES/EBU
∗
stereo input, with hardware sample rate converter
(up to 96 kHz) and programmable digital gain
•
6 digital AES/EBU
∗
stereo outputs (up to 192 kHz) with programmable
digital gain
•
1 digital AES/EBU
∗
stereo sync input (up to 192 kHz in play and record)
•
1 standard Word Clock input (up to 96 kHz)
•
1 standard Word Clock output (up to 96 kHz)
•
1 video sync input
•
1 SMPTE/LTC (Linear Time Code) sync input
VX1222HR main hardware features
All features of the VX1221HR, plus:
•
2 balanced
∗∗
analog mono line inputs, with software programmable
analog and digital gain
•
12 servo-balanced
∗∗∗
analog mono line outputs, with software
programmable analog and digital gain
•
192 kHz / 24-bit converters
•
Maximum level on analog inputs and outputs: +24 dBu
Note: The digital outputs always play the digital version of the corresponding analog output.
The selection of the AES/EBU input excludes the selection of the analog inputs.
Main software features
•

can be used as S/PDIF interface as well
∗∗
can be used with unbalanced signals
∗∗∗
Electronically servo-balanced outputs provide automatic level adjustment to accommodate
either balanced or unbalanced lines
