CHAPTER 1 DRAWMER M-Cloc k Plus M-Clock DMS-5 AES GRADE 1 MASTER CLOCK AND DUAL SAMPLE RATE CONVERTER INTRODUCTION The M-Clock Plus is a high stability master clock generator offering clock rates from 44.1 to 192kHz, coupled to two sample rate converters, which allow material to be re-sampled and syncronised to the selected high precision clock. In addition to the internal clocks, M-Clock Plus can sync to either external word clock or clocks from AES/EBU signals.

INSTALLATION The DMS-5 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.

CHAPTER 2 CONTROL DESCRIPTION The Drawmer M-Clock Plus supplies ten word clock outputs, as well as two simultaneous outputs of S/PDIF and AES/ EBU allowing you to synchronize your digital workstation, A/D converter, digital mixer and a host of other digital audio equipment through one stable and very accurate unit.

MODE With the sample rate set to EXT a switch controls the mode of display enabling you to read the incoming sample rate in your preferred manner. Pressing the switch toggles through the three modes of FREQ, ±PPM and ±%, with led indication. FREQ Displays the actual frequency to four decimal places upto 192kHz. ±PPM Displays the nominal sample rate with +/- ppm (part per million) error indication for 32, 44.1, 48, 88.2, 96 & 192KHz.
