This symbol, wherever it appears, alerts you to important operating and maintenance instructions in the accompanying literature. Please read the manual. 1) Read these instructions. 2) Keep these instructions. 3) Heed all warnings. 4) Follow all instructions.
DM84 Installation Guide Introduction The purpose of this guide is to assist in the setup and operation of a typical DM84 system. This guide assumes familiarity with the DM84 Digital Audio Processor, 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.

DM84 Installation Guide Hardware Installation Installing the DM84 System Into a Rack The DM84 occupies a single rack space and there are no special ventilation requirements. Mount with 4 rack screws using the appropriate mounting holes. It is recommended to use nylon washers to prevent damage to the front panel’s finish when tightening the screws. For North American installations, connect the Power Cable supplied with the unit between the DM84 and a stable power source.
DM84 Installation Guide Phantom Power The DM84 supplies +15 VDC phantom power to the audio inputs via a programmable switch and two 2 k resistors. Microphone Number 2: From Specification Sheet: Vph = 15 V - (1k)(.002A) Vph = 15 V - 2V = 13 V +15V 2k ohm Pin 2 or 4 + Pin 1 or 5 - Phantom On/Off (from Micro Controller) 2k ohm PGA To CODEC - - Pin 3 Since the calculated Vph is greater than the Vph from the microphone specification sheet, this is an acceptable situation.
DM84 Installation Guide When the DM84 output is connected to a balanced input, wire it as shown here. DM Out Destination + + - Shield - DM Out to Balanced Input (3-Wire) Programmable Inputs Programmable inputs are provided to enable external control over a variety of parameters. Each input can respond to either a contact closure or a continuous voltage. The following illustrates common connections to the programmable input pins. (See also Programmable Inputs and Outputs Wiring Diagram.
DM84 Installation Guide DM84 Rear Panel LecNet 2 Programmable Inputs and Outputs Expansion I/O Ports Expansion I/O ports The four RJ45 connectors on the rear panel are used to interconnect LecNet2™ units together. These ports are only used to transfer digital audio information via the Digital Audio Network Interface (DANI) between the units.
DM84 Installation Guide DANI Bus Expansion I/O ports The four RJ45 connectors on the rear panel are used to interconnect LecNet2™ units together. These ports are only used to transfer digital audio information via the Digital Audio Network Interface (DANI) between the DM Series processors that are interconnected. WARNING: The Expansion I/O connectors are NOT EtherNet, CobraNet or any other network based device interconnects.
DM84 Installation Guide Control System Interconnections In addition to a Windows® based computer system, the DM84 can be controlled by external serial control system using the RS-232 interface, such as those from Crestron® and AMX®.
DM84 Installation Guide Installing LecNet2™ Software and USB Driver The LecNet2 USB drivers are installed from the Installation Disk which comes with each processor by running the LecNet2 Device Installer. Normally, this is done before connecting a processor for the first time, however, it can done afterwards if necessary. The driver installation only needs to be done once.
DM84 Installation Guide Manual Installation If the USB drivers have not been pre-installed on a PC prior to connecting a LecNet2 device for the very first time, you may install the manually if you wish. On Windows XP and Vista operating systems, the Found New Hardware Wizard will open when the device is detected. It will walk you through the process of installing the LecNet2 drivers. To proceed, you will need the LecNet2 Installation Disk.
DM84 Installation Guide Initial Setup The initial setup of a DM84 system is a relatively simple three step process: connect the unit to the computer, turn on the computer and select the appropriate control panel, preset the input, matrix and output. This process assumes that LecNet2™ and, if necessary, the USB driver have been previously installed. If they have not been installed, please refer to Installing LecNet2™ Software and USB Driver.
DM84 Installation Guide The DM84 can be configured in the installation or a configuration file can be created off line in advance. The minimum required setup to pass audio includes: Inputs, Matrix and Outputs. Input and output filters, compressors and delays are used to tailor the system for specific audio situations. These parameters are set up through the Control Panel GUI. Inputs Matrix Outputs IMPORTANT: Any changes made during setup must be saved in the unit via the preset menu.
