DM Series Installation Guide
Rio Rancho, NM 5
Introduction
The purpose of this guide is to assist in the setup and
operation of a typical DM system. This guide assumes
familiarity with the DM Series Digital Audio Processors,
its components and software menus and setup screens.
To get the most out of the DM system, it is suggested
to review the information presented in the DM Series
Reference Manual.
A detailed online Help is also available to assist in
the setup and operation of a DM system using the
USB interface and a Windows® 2000 or Windows®XP
computer system. In addition to assistance setting
up and operating the DM system, the Help includes a
complete listing of the DM General Commands. These
commands can be used to setup and operate the DM
system via external devices using either the USB or
RS232 serial port.

Installing the DM System into a Rack
The DM1624 and DM1612 occupy two rack spaces.
The DM812 occupies a single space. There are no spe-
cial ventilation requirements. Mount with 4 rack screws
using the appropriate mounting holes. It is recommend-
ed 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 DM and a
stable power source. DM processors have internal
switching power supplies that can tolerate voltages
ranging from 100 VAC to 240 VAC. Use an approved
power cable for installations outside North America.
Cables
It is recommented to use lacing bars for cable strain
relief when mounting in a rack. Use only professional
audio cable with proper shielding - typically, two con-
ductor plus ground/shield.
Audio Connections
The analog audio inputs and outputs are connected
through 5 pin de-pluggable connectors. Strip the insu-
lation back 1/8 to 3/16” but do not tin (apply solder to)
the leads. Insert the wire into a de-pluggable connec-
tor, leaving less than 1 mm of bare wire exposed, then
tighten the retaining screw.
Caution: Do not over tighten the retaining
screw.
Note the labeling on the DM Chassis for the positive
and negative leads. Ground is shared between two
connections (the center pin). For balanced connec-
tions, all three leads can be connected.
NOTE: The DM Series does not have a “pin 1
problem.”
Audio Connection Guidelines
Unbalanced and balanced input connections use the
following guidelines.
Audio Inputs
Unbalanced Sources
Unbalanced audio sources (positive and ground)
include items such as consumer VCR’s, DVD play-
ers, etc., and may use both two wire and three wire
cables. In either case, the positive output from the
source should be connected to the appropriate positive
(+) input on the DM. The shield or negative (–) output
should be connected the DM’s negative (–) input. Two
wire cables should have a jumper between the DM
negative input and ground. Three wire cables should
have the shield connected to the DM’s ground input and
the shield and negative (–) leads joined together at the
unbalanced source end.
WARNING: Do not activate phantom power for
unbalanced sources. Refer to online help files
after the software is installed.
Balanced Sources
Balanced differential sources from external equipment
and microphones should be wired according to Bal-
anced source to DM input (3-Wire). (See illustration.)
When connecting balanced sources to the DM, it is im-
portant to not connect chassis ground (shield) to either
signal conductor.

Examples:
Microphone Number 1;
From Specification Sheet: Vph(min) = 11 V
Imic(typical) = 4 mA
Vph = 15 V - (1k)(.004A)
Vph = 15 V - 4V = 11 V
Since the calculated Vph is equal to Vph from the
microphone specification sheet, this is a marginal situ-
ation.
Microphone Number 2:
From Specification Sheet: Vph(min) = 9 V
Imic(max.) = 2 mA
Vph = 15 V - (1k)(.002A)
Vph = 15 V - 2V = 13 V
Since the calculated Vph is greater than the Vph from
the microphone specification sheet, this is an accept-
able situation.
Audio Outputs
All outputs are a balanced differential configuration.
Some outputs include an attenuator to reduce the sig-
nal to mic level. Use the outputs marked as MIC/LINE
OUTPUTS for mic level applications. Using the other
outputs marked LINE OUTPUTS with control panel at-
tenuation can result in up to 40 dB of additional noise.
NOTE: Using a Line Output with digital attenuation
applied with the Control Panel to achieve Mic Level
will result in added noise.
When the DM output is connected to a balanced input,
wire it as indicated in DM Out to Balanced Input
(3-Wire). Select Mic or Line (as appropriate) either
from the front panel LCD interface or via the software
GUI.
When the DM output is conencted to an unbalanced
input, wire it as indicated in DM Out to Unbalanced
Input (3-Wire), or DM Out to Unbalanced Input
(2-WIre).
Phantom Power
The DM supplies +15 VDC phantom power to the audio
inputs via a programmable switch and two 2 k resistors.
(See illustration below.)
However, the true phantom power available at the
microphone may be less due to voltage drop across the
microphone itself (source resistance). In some cases,
the voltage drop may be enough to result in marginal
performance. The following formula can be used to
determine how much phantom power will be available to
a particular microphone.
Vph = 15 V - (1k)(Imic)
Where:
Vph = the actual voltage available at the microphone.
(Microphone specifications list this as the mini-
mum recommended phantom voltage value. To
minimize problems, the calculated Vph should
exceed this value.)
Imic = the current draw of the microphone. (Refer to
individual microphone specifications for this
value.)

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 Program-
mable Inputs and Outputs Wiring Diagram.)
No external pull-up resistors are necessary because
each programmable input is internally pulled up through
a 100K resistor to +5V. When using a continuous volt-
age with one of the programmable inputs, the function
of the programmable input must be set to either Analog
In Control or Analog Out Control on the Program-
mable Inputs control tab in the Control Panel GUI.
See the Programmable Input tab in the Control Panel
software Help for setting all programmable input param-
eters.
Programmable Outputs
Programmable outputs are used to indicate either
channel activity or the current state of a programmable
output. Each programmable output is the electrical
equivalent of a contact closure to ground. When a
programmable output is “active”, it conducts current to
ground. When the programmable output is “inactive”,
no current flows to ground. The maximum usable volt-
age for the programmable outputs is 40 V and they will
safely conduct up to 100 mA DC continuous. Following
are some typical uses for the programmable outputs.
Note: The diagram shows an external DC source
powering the relay coil. This is necessary
whenever coil voltages exceed 5 V.

among all devices.
Both LEDs and 5V relay coils can be powered by the
+5 V DC pins on the programmable input connector, as
long as the maximum combined current for all LEDS
and relay coils does not exceed 100 mA.
Programmable Input/Outputs Connections
Looking at the male connector on the rear panel of the
processor, the pinouts are as follows:
Expansion I/O Ports
(DM1624 shown)
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.
WARNING: The Expansion I/O connectors are
NOT EtherNet, CobraNet or any other network
based device interconnects. Connecting them
to Ethernet, CobraNet or other network based
device may cause damage to either unit.
In a stacked configuration, one unit must be configured
as the Master unit and the others as Slave units. Con-
figuring a unit as a Master or a Slave can be done using
the front panel LCD and controls or the Control Panel
GUI interface.
Note: In order to use the convenient Control Panel
GUI, LecNet2™ must be installed on the attached
computer system. (See Installing LecNet2™
Software and USB Driver.)
To connect the Master/Slave units, plug one end of a 12
inch Cat5e cable (two are supplied with each with unit)
to the transmit (TX) port on the Master unit, and con-
nect the other end to the corresponding receiver (RX)
port on the Slave unit immediately below the Master.
Repeat this procedure with the second Cat5e cable.
(See Expansion Port Digital Audio Network Interface
Interconnection Diagram.)
CAUTION: Do not connect these ports to each
other on a single unit, and to not cross the
cables between the units.
Master/Slave Configuration
When stacking multiple units, one unit is always set as
the Master and all subsequent units are set as Slaves.
The LCD interface is used to do this.

Installing LecNet2™Software and USB Driver
LecNet2™ is a Graphic User Interface (GUI) designed
to allow easy setup and monitoring of DM compo-
nents using Windows®2000 or XP computer systems.
LecNet2™ includes the necessary Control Panels to
configure and monitor all the DM series products plus
the Venue Modular Receiver system.
Installing LecNet2™Software
1. Use the computer system’s control panel to remove
any previously installed versions of LecNet2™
software. (This will ensure you are using the latest
release.)
2. Insert the LecNet2™ program disk supplied with
your system into the computer system’s CD-ROM
drive.
3. The CD should automatically start the installation
procedure. If it doesn’t, click “Start” on the WIn-
dows Task Bar then click “Run...” Enter the Drive
number followed by “Setup.exe” then click OK.
4. Follow the on-screen instructions to install the Lec-
Net2 software.
Installing the LecNet2™USB Driver
There are two methods of connecting a Windows®-
based computer system to the DM component, either
via a USB cable or an RS-232 cable. Although the USB
port offers significantly increased speed and conve-
nience over standard RS-232 links, it does require the
installation of a LecNet2™ USB driver.
The LecNet2 USB driver is not part of the standard
Windows®2000 and XP driver libraries. As a result,
connecting a computer system to a DM system for
the first time is different than subsequent installations.
There are a few minor differences between installing
the LecNet2 USB drivers on a Windows 2000 versus a
Windows XP system.
USB Driver Installation Windows XP
When the DM is connected to a Windows XP computer
system for the very first time, the Windows®“New Hard-
ware Found Wizard” automatically opens.
First Time Installation
When a LecNet2™ device is connected to the PC for
the very first time, the Windows Found New Hardware
Wizard automatically opens. Use the following pro-
cedure to install the LecNet2™ USB driver using the
Wizard.
1. Place the LecNet2™ Installation Disk in the PC’s
CD-ROM drive.
2. On the first page of the Wizard, select the option In-
stall from a list or specific location (Advanced)
and click Next> to continue.
3. Select “Search for the best driver in these loca-
tions”, then check “Search removable media
(floppy, CD-ROM...)” and click Next> to continue.
4. Windows searchs the CD for the driver and when it
has found it, it is likely that a dialog will open warn-
ing you that the driver has not passed Windows
Logo Testing, click Continue Anyway.

5. When the driver installation is complete, the final
page of the Wizard appears. Click Finish to com-
plete the LecNet2™ USB driver installation.
Installation Additional Units
(or LecNet 2™Devices)
The Windows XP operating system regards all Lec-
net2™ devices as separate USB devices because each
has a unique serial number. Because of this, Windows
XP will want to install the USB driver every time it
encounters a LecNet2™ device whose serial number
it does not recognize. However, if the LecNet2™ USB
driver has already been installed at least once before
on the computer system, the process is simplified be-
cause the LecNet2™ installation disk is not required.
Use the following procedure if the LecNet2™ USB
driver was previously installed on the computer system.
1. On the first page of the Wizard, select Install the
software automatically (Recommended) and
click Next> to continue.
2. Windows discovers the previously installed USB
driver. It is likely that a dialog will open warning you
that the driver has not passed Windows Logo Test-
ing. Click Continue Anyway.
3. When the driver installation is complete, the final
page of the Wizard appears. Click Finish. It is now
possible to connect to the LecNet2™ device.

USB Driver Installation (Windows 2000)
First Time Installation
When a LecNet2™ device is connected to a comptuer
system running the Windows®2000 operating system
for the very first time, the Windows Found New Hard-
ware Wizard automatically opens.
Use the following procedure to install the LecNet2™
USB driver using the Wizard.
1. Connect a cable between the DM processor USB
port and the computer system. Place the Lec-
Net2™ Installation Disk in the computer system’s
CD-ROM drive and click Next> to continue.
2. Select “Search for a suitable driver for my de-
vice (recommended)” and click Next> to continue.
3. Check “CD-ROM drives” then click Next> to search
the LecNet2™ CD for the USB driver.
4. When it is found, the LecNet2™ device name will
be displayed. Click Next> to install the driver.
5. When the driver installation is complete, the final
page of the Wizard appears. Click Finish. It is now
possible to connect to the LecNet2™ device.

Initial Setup
The initial setup of a DM 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.
1) Connect the computer system to the DM unit using
either the BLACK DB9 to stereo mini (TRS 1/8”)
cable for RS-232 communications or the USB cable
for USB control. (Both cables are included with the
unit.)
Note” Only one DM unit at a time can be
connected to the computer system using the RS-
232 cable. Multiple units may be connected to the
computer system using a USB hub.
2) Turn the computer system on. After the boot se-
quence is complete, click Start, then All Programs.
3) Select LecNet2, then select the control panel from
the list for the DM unit being set up.
4) If the “Just a Reminder” dialog appears, click OK
to continue.
5) Click Connection on the Main Menu bar, then
select the type of connection between the computer
system or external control system and the DM unit.
The choices are:
USB - used when the computer is connected
to the DM unit via the front or rear panel
USB port.
Network - One or more DM devices may be
made available for network connections
by connecting them to a gateway server
acting as a middleman, receiving
commands for a DM over a network
connection, and forwarding them to the
DM device connected via USB.
Extron IPL T S - One or more DM devices
may be made available for network
connections by connecting them to
an Extron IPL T S ethernet control
interface. The IPL T S interface acts as
a middleman, receiving commands for a
DM device over a network connection,
and forwarding them to the device via an
RS232 port. To work as a gateway server
the IPL T S interface must be a member
of some local area network (LAN) or
the Internet, by means of an Ethernet
connection.
Serial->COM1 - An RS-232 port for RS-232
communications between the DM and
the computer sytsem, or for connecting
the DM to an external control system
such as those made by Crestron®or
AMX®.
Serial->COM2 - Same as above.
Go Offline - No Connection Made, this mode
can be used for off line configuration and
is the default mode.

Inputs Matrix Outputs
The DM 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. While these parameters
can be set up through the front panel LCD and controls,
the Control Panel GUI offers a much more robust and
intuitive interface.
Initial Setup Hints
1) The GUI interface is quite intuitive. As a recom-
mended first step, we suggest you select Labels
from the Menu Bar and type in all the input and
output labels. This will simplify further setup steps
because you will be able to easily keep track of
which input or output you are adjusting.
2) The right click is powerful in this interface. You can
activate quick access to a number of setup func-
tions (for example - right click in any input box in
the INPUTS tab ). It also allows some powerful
cut and paste capabilities - especially in the matrix
setup and the filter (both input and output).
3) Store startup settings in a startup default preset.
(See Storing and Recalling Presets in the online
HELP application.)
4) Presets will take about 4 seconds to switch due to
the many parameters in the unit - audio will switch
off temporarily during a preset switch to avoid feed-
back. If you need quicker response with no inter-
ruption to the audio, use macros instead - try using
the macro recorder for making any changes. The
only changes that cannot be made in a macro are
filter adjustments. such as EQ.
5) Store presets after changes are made and not be-
fore they are made.
6) Help is always available by clicking Help on the
Main Menu Bar. This Help is a comprehensive
resource and includes the latest revisions to the
software and firmware.
IMPORTANT: ANY CHANGES MADE DURING
SETUP MUST BE SAVED IN THE UNIT VIA THE
PRESET MENU.

able to answer your setup and/or technical questions or
