4 GR2 User Guide
Introduction
This User Guide provides a quick reference to the installation and operation of the GR2 audio
zone mixer. We refer to two types of user in this guide: The Installer configures the unit for the
application and is assumed to have technical knowledge in audio system interconnection and
setup. The Operator is the day to day user of the unit and does not require technical knowledge.
This guide provides technical information for the installer. A Configuration Sheet is included at the
rear of this guide so that the installation settings and instructions for the operator may be logged.
The GR2 offers many configuration possibilities to satisfy the custom requirements of a multitude
of architectural and utility sound applications. To take advantage of this capability, we
recommend that the installer studies the system block diagram to fully understand its signal flow
and control possibilities.
