CHAPTER 1 DRAWMER A2D2 DMS-3: AES GRADE 1 DUAL OUTPUT A/D CONVERTER INTRODUCTION Microphones are analogue, speakers are analogue, storage is mostly digital and signal processing can be either analogue or digital, software or hardware based. At some point in the signal path, a high quality Analogue-to-Digital converter is required, which faithfully reproduces analogue signals in the digital domain. Step up the Drawmer A2D2...

INSTALLATION The DMS-3 is designed for standard 19" rack mounting occupying 1U of rack space. Avoid mounting the unit directly above power supplies or amplifiers that radiate significant amounts of heat. If the unit is to be used in a mobile situation, it is strongly recommended that the rear of the unit is supported in the carrying rack to avoid bending the front panel rack mounting ‘ears’. Use fibre or plastic washers to prevent the front panel becoming marked by the mounting bolts.

CHAPTER 2 CONTROL DESCRIPTION The Drawmer DMS-3 A2D2 has been meticulously designed to faithfully, and transparently recreate your analogue signal in digital in as simple and intuative method as possible. A high quality Burr Brown input stage has been incorporated, coupled with the AES Grade 1 digital converted outputs, making the A2D2 perfect for recording, mastering and post- production from all of your analogue to digital devices.

Output Level Metering An accurate 24 segment peak reading LED bar meter shows the incoming signal level from -50dBfs to 0dBfs plus separate overload LEDs for each channel. QUICK SETUP PROCEDURE . Plug in the left and right channel inputs on the rear of the unit, preferably using balanced wiring. . On the front panel set the “Input Level for 0dBfs” mode switch to the correct setting - calibrated if in a studio and the entire system is calibrated, or variable in any other situation. .
