Introduction
The purpose of this guide is to assist in the setup and 
operation of a typical DM84 system. This guide as-
sumes familiarity with the DM84 Digital Audio Proces-
sor, its components and software menus and setup 
screens. To get the most out of the DM84 system, it is 
suggested to review the information presented in the 
DM84 Series Reference Manual.
A detailed online Help is also available to assist in the 
setup and operation of a DM84 system using the USB 
interface and a Windows
® 
XP, Vista or 7 operating sys-
tem. In addition to assistance setting up and operating 
the DM84 system, the Help includes a complete listing 
of the DM84 Commands. These commands can be 
used to setup and operate the DM84 system via exter-
nal devices using either the USB or RS232 serial port.
