CHAPTER 2 SIMPLE CONNECTION GUIDE AUDIO CONNECTIONS Word Clock / AES-3id Use only good quality 750 digital or video coax (not aerial downlead) cable for the word-clock signals, terminated with the correct type of 75Ω BNC connectors - inferior cables will introduce jitter and will completely undermine the performance benefits which might be achieved by using a master clock in the first place! 6 AES3id calls for unbalanced 75 ohm connections, which make its hardware requirements the same as S/PDIF connecti

CONTROL DESCRIPTION DISPLAY A Blue/White LCD display with three switchable modes of operation: FREQ, ±PPM and ±%. The mode that is displayed during power down is saved for the next session. The display accuracy is 2ppm at all sample rates up to 768kHz, or 0.1Hz increments @ 48KHz sample rate MODE 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.
