AMR (Audio/Modem Riser)

AMR is a riser card that supports sound or modem function. Because 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.
