Euphonix SH612 Studio Hub User Guide

Chapter 1: Getting Started

1.1 Introduction to the SH612

The SH612 provides the central point from which to send MADI and synchronization

signals in System 5 and R-1 configurations. Since each SH612 is configured and in-

stalled by Euphonix for use with the R-1 and/or System 5, you will not often need to

modify most of its parameters. This User Guide provides a technical reference for the

SH612 but will not cover system hookup in general (see the System 5 Technical Over-

view in your manual binder).

All SH612 functions can be controlled from its front panel or through a software inter-

face connected to System 5 or R-1. The SH612:

• provides the master clock signal for all digital audio components;

• routes and merges the 28-channel, 48 kHz MADI output streams from all

connected digital audio devices and transmits them to the DF64 (System 5) or

AudioDeck (R-1) MADI inputs as 56- or 28-channel MADI streams. At

96 kHz, signals are not merged but simply transmitted to the DF64.
