An audio Modem riser (AMR) is a quick riser growth slot at the Motherboard of positive Intel PCs together with Pentium III and IV. Its Availability is likewise seen in AMD Athlon and AMD Duron PCs. The audio Modem riser is designed as an smooth and inexpensive manner to contain special sound playing cards and modems into a machine. The AMR slot turned into first brought by means of Intel in 1998 as a way to permit motherboard producers to use an Analog Input/Output (I/O) machine for audio and modem Functions on an enlargement board.
Also referred to as an AMR slot.
The AMR become designed to decrease the fee of a Laptop machine in several approaches:
The AMR has a complete of forty six pins, arRanged in rows of 23 pins every. It uses analog I/O audio capabilities that require a Software driving force and a modem Circuitry loaded with a Codec Chip to translate analog and virtual indicators. The small riser board fits directly into the motherboard. It is referred to as a riser board because it does now not lay flat at the motherboard however rises above it.
The AMR provided a way to feature superior audio and modem layout at minimal cost for this reason permitting producers to design custom sySTEMs. At the same time, motherboards did not have integrated audio and modem functionalities. However, even though the AMR essentially replaced the PCI Slot, many unique Device producers did not need to use it because it had restricted competencies consisting of no plug-n-play.
The AMR slot was superseded by means of the communications and Networking riser (CNR) and the advanced communications riser (ACR), which additionally became out of date. Then generation took a one of a kind turn, the usage of audio Interfaces integrated at once onto the motherboard, even as modems endured to use PCI slots. However, there is a high-defiNition Multimedia riser (HDMR) slot evolved by Asrock, that is used for the HDMR card that has v92 modem features.
When we refer to AMR as an acronym of Audio Modem Riser, we mean that AMR is formed by taking the initial letters of each significant word in Audio Modem Riser. This process condenses the original phrase into a shorter, more manageable form while retaining its essential meaning. According to this definition, AMR stands for Audio Modem Riser.
