Introduction

Thank you for choosing the SAM 24-Bit ADAT / S/PDIF Mixer &
Format Converter. The SAM has six different selectable modes with
which to convert between ADAT Optical Digital Interface and S/PDIF
interface signals. SAM can convert in either direction. In order to
deliver the highest conversion quality, the SAM features “lossless”
24-bit transfers in direct modes, and in mixer mode provides high­resolution 56-bit internal processing for remarkable transparency.
The SAM is therefore the perfect studio “go between” for transfer­ring audio tracks to and from ADAT machines, computer digital
audio cards, DAT machines, Digital Audio Workstations, external
converters or any other devices equipped with S/PDIF and/or ADAT
Optical digital interface technology. Keep all of your transfers,
mixes, and sub-mixes in the digital domain with the latest in ADAT
Optical Digital Interface & S/PDIF conversion technology - the SAM.
