CHAPTER 1 DRAWMER DMS-4 M-Clock Lite AES GRADE 1 MASTER CLOCK INTRODUCTION It is now widely accepted that one of the essential requirements for high quality digital recording is a first class, high stability master clock generator. These can be complicated devices with many added features, which although useful, may be surplus to requirements. The aim of M-Clock Lite is to provide a simple, high quality clock generator, which is forward compatible with high speed clocks predicted for the future.

INSTALLATION The DMS-4 is designed for standard 19" rack mounting and occupies 1U of rack space. Avoid mounting the unit directly above power amplifiers or power supplies 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.
