A PMC audio card with front and rear I/O based on the Crystal CS4281 CrystalClearTM PCI Audio Interface controller and the Crystal CS4299 CrystalClearTM SoundFusionTM Audio Codec ’97. The PMC481 features four audio connections via the front panel using 3.5mm stereo connectors.
Optional the audio connections can be made via the rear I/O of the PMC481 using the:
> PIM481-J (PMC I/O Module, with four 3.5mm stereo connectors) or the
> PIM481-DSUB ((PMC I/O Module, with D-sub for rear I/O).
The PIM481-J and PIM481-DSUB can be mounted on a rear transition module (RTM). Pictures of these I/O modules can be found on our website.
The audio interface consists of a line input, a microphone input, a line output and a speaker output with an oncard stereo amplifier. To prevent that the onboard amplifier shortly draws a too high current from the +12V supply the PMC481 has an onboard current limiter which limits the current to (a little less than) 500mA.
Driver support for the Crystal CS4281 is included in commonly used operating systems, like Windows (up to XP), Linux and VxWorks (refer to OpenSound).
