Eight channel AD Converter for 24bit / 96kHz
Introduction
The Fostex Model AC2496 is a 24 bit/96kHz compatible (compatible only to S/P DIF)
professional-use 8 channel A/D converter that converts analog input signals to digital
signals (adat or S/P DIF). It can be utilized to increase the number of inputs of Fostex
digital multirecorders D1624/D2424 and for substituting inputs of digital mixers and
personal computers.
Functions of the Model AC2496 can be extended accor

Main features of the AC2496 The AC2496 is a professional use high quality 24 bit, 96kHz compatible 8 channel A/D converter for converting analog signals to digital signals. Conversion to digital signals can be selected for S/P DIF or adat, depending on the application. Furthermore, by installing the option, it will be possible to also output AES/EBU format digital signals so it can be used to extend the number of digital multirecorder analog inputs and to substitute the inputs of digital mixer
