FEATURES
VX822HR and VX820HR 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.
VX820e and VX822e are audio cards for PCI EXPRESS
​ TM ​
(PCIe
​ ® ​
)
bus. They are in PCI EXPRESS ​ TM ​ x1 format and can thus be plugged
into ​ ​ any ​ ​ PCIe ​
® ​
​ ​ slot
(x1, ​ ​ x2, ​ ​ x4, ​ ​ x8, ​ ​ x16, ​ ​ x32).
