Introduction - Design Concept

1. INTRODUCTION

In purchasing the new SM Pro Audio A08, you have acquired an ADAT® format multi-channel
digital to analog converter of high class that meets many of the demands of the home/pro studio.

The market size for digital audio interfaces and computer based digital recording/editing has
increased in a massive way. With systems available at very low prices, more and more users are
utilizing this technology. Many current digital systems also feature ADAT® compatible connectivity
to facilitate the simple connection between digital devices from different manufacturers.

About the ADAT® format...

The ADAT® protocol is a digital audio transfer protocol format developed by ALESIS Corporation.
It allows 8 channels of digital audio data to be transferred through a single optical cable (light
pipe). Since the development of ADAT® many professional companies have adopted this format
as the defacto standard for the reliable transfer of high quality multi-channel digital audio
between devices. You can now find ADAT® I/O (input and output) connections provided on a
wide range of digital audio equipment from digital mixers, recorders, multi-channel microphone
pre-amps and the like.

The SM Pro Audio A08 is an extremely portable multi-channel analog to digital audio converter. It
reliably converts 8 channels of analog audio to pristine 24-bit digital audio while providing the out-
put via the popular ADAT® format. This single rack unit can now solve many of the connectivity
issues which are raised in a large range of situations.

The A08 is the perfect addition to your ADAT® compatible mixer, recorder, computer based audio
interface, etc. 

Add more connectivity and analog inputs to your ADAT® compatible devices!
