ECIFICATIONS 2 i See 9 DISCLAIMER d E 15 Introduction 1 INTRODUCTION The Sycos is a high resolution Analog to Digital and Digital to Analog converter Its concept originates from the top range D amp R broadcast consoles units It is designed to be used in demanding recording and broadcast applications where the audio converters need to be 24 bit and sample rates up to 96kHz are a necessity Modern hard disk recording systems deliver the kind of impressive performance and track capacity that can measure up to the best studio equipment available Nonetheless the high quality of today s processing options can t be exploited to full effect when used with standard sound cards because the A D converters in these cards easily distort and because interference generated from the clock frequencies inside the computer housing degrades the signal to noise ratio The remedy is to use a high quality converter housed in an external device so that the signal can be patched into the computer harddisk system without loss or hassle The Sycos converter is the answer to convert stereo analog signals into digital the line input of the Sycos can be connected directly to the mixing console s output thereby preserving the sound quality of the analog signals as well as their impressive dynamic range From the Sycos s digital outputs the signal would then be routed to a master recorder or t
