Focusrite MH434 A/D Card for the ISA220

The optional A/D card can be factory fitted or purchased later and retro fitted as and when required, to suit your recording budget. With the addition of the Stereo A/D card the ISA 220 and 430 can be used as high-quality mono/stereo tracking converters or at mix down as a stereo converter channel for final mastering. At the heart of the Stereo A/D card is a high quality 24-bit 96KHz Delta Sigma converter running at 128KHz over-sampling for maximum conversion performance. Focusrite proprietary designs are used for all internal clocking and phase lock loop circuits to guarantee the absolute minimum jitter possible, whether free running or locked to wordclock or ProTools Superclock. When recording to non-24-bit destinations 16 and 20-bit dithering can be selected to ensure the highest quality digital conversion for any format.
