AMR (Audio/Modem Riser)
|AMR is a
riser card that supports sound or modem function.
CPU computing power is getting stronger, the digital processing job can
be implemented in main chipset and share CPU power. The analog
conversion (CODEC) circuit requires a different and separate circuit
design, it is put on AMR card. AOpen motherboard implements sound CODEC
on board, but reserve AMR slot for the option of modem function. Note
that you can still use PCI modem card or preferred sound card.
A few AMR cards have been imported into
NZ, but after various trials it was decided that the technology was not
reliable enough over the NZ telephone network for modems, and the sound
wasn't as good as some of the cheapest ($20) sound cards. Therefore do
not expect to find AMR cards available here.
