16 Audio Interface
The JRexplus LX supports an AC'97 V2.3 audio codec with 16 bit resolution and 48 kHz sample rate. The
interface includes LINE OUT, LINE IN and MICROPHONE IN. The AC'97 specification provides low cost, high
quality sound. This is done by embedding half of the required technology in the Southbridge and the other
half in a separate chip from an OEM supplier. For signal levels see the AC'97 Component Specification
(Intel
® ).
