Hardware Installation
Installing the DM System into a Rack
The DM1624F and DM1612F occupy two rack spaces.
The DM812 occupies a single space. 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.
Do not obstruct the fan port on the 2RU models.
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 conductor plus ground/shield.
Audio Connections
The analog audio inputs and outputs are connected
through 5 pin de-pluggable connectors. Strip the insulation back 1/8 to 3/16” but do not tin (apply solder to)
the leads. Insert the wire into a de-pluggable connector, leaving less than 1 mm of bare wire exposed, then
tighten the retaining screw.
Audio Inputs
Unbalanced Sources
Unbalanced audio sources (positive and ground)
include items such as consumer VCR’s, DVD players, 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 important to not connect chassis ground (shield) to either
signal conductor.
Retaining Screw
(Do not overtighten)
5-pin depluggable
connector
Do not leave more than
1 mm of exposed wire
beyond the connector.
Do not tin (apply solder
to) leads
Note the labeling on the DM Chassis for the positive
and negative leads. Ground is shared between two
connections (the center pin). For balanced connections, all three leads can be connected.
NOTE: The DM Series does not have a “pin 1
problem.”

Phantom On/Off
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)(I
Where:
mic
)
DM Series Installation Guide
Since the calculated Vph is equal to Vph from the
microphone specification sheet, this is a marginal situation.
Microphone Number 2:
From Specification Sheet: Vph(min) = 9 V
I
(max.) = 2 mA
mic
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 acceptable situation.
Audio Outputs
All outputs are a balanced differential configuration.
Some outputs include an attenuator to reduce the signal 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 attenuation 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 (2WIre).
Vph = the actual voltage available at the microphone.
(Microphone specifications list this as the minimum recommended phantom voltage value. To
minimize problems, the calculated Vph should
exceed this value.)
I
= the current draw of the microphone. (Refer to
mic
individual microphone specifications for this
value.)
Examples:
Microphone Number 1;
From Specification Sheet: Vph(min) = 11 V

Vph = 15 V - (1k)(.004A)
Vph = 15 V - 4V = 11 V

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.)
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 voltage 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.
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:
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 voltage 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 parameters.

In a stacked configuration, one unit must be configured
as the Master unit and the others as Slave units. Configuring 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 connect 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.

DM Series Installation Guide
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 RS232 cable. Multiple units may be connected to the
computer system using a USB hub.
2) Turn the computer system on. After the boot sequence 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.
Connect Menu
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.
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.
16
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.
LECTROSONICS, INC.
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.
DM Series Installation Guide
5) Store presets after changes are made and not before 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.
Initial Setup Hints
1) The GUI interface is quite intuitive. As a recommended 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 functions (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 feedback. If you need quicker response with no interruption 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.

Service and Repair
If your system malfunctions, you should attempt to correct or isolate the trouble before concluding that the equipment needs repair. Make sure you have followed the setup procedure and operating instructions. Check the interconnecting cables and then go through the TROUBLESHOOTING section in this manual.
We strongly recommend that you do not try to repair the equipment yourself and do not have the local repair shop
attempt anything other than the simplest repair. If the repair is more complicated than a broken wire or loose connection, send the unit to the factory for repair and service. Don’t attempt to adjust any controls inside the units. Once
set at the factory, the various controls and trimmers do not drift with age or vibration and never require readjustment.
There are no adjustments inside that will make a malfunctioning unit start working.
LECTROSONICS’ Service Department is equipped and staffed to quickly repair your equipment. In warranty repairs
are made at no charge in accordance with the terms of the warranty. Out-of-warranty repairs are charged at a modest flat rate plus parts and shipping. Since it takes almost as much time and effort to determine what is wrong as it
does to make the repair, there is a charge for an exact quotation. We will be happy to quote approximate charges by
phone for out-of-warranty repairs.
Returning Units for Repair
For timely service, please follow the steps below:
A. DO NOT return equipment to the factory for repair without first contacting us by letter or by phone. We need to
know the nature of the problem, the model number and the serial number of the equipment. We also need a
phone number where you can be reached 8 A.M. to 4 P.M. (U.S. Mountain Standard Time).
B. After receiving your request, we will issue you a return authorization number (R.A.). This number will help speed
your repair through our receiving and repair departments. The return authorization number must be clearly
shown on the outside of the shipping container.
C. Pack the equipment carefully and ship to us, shipping costs prepaid. If necessary, we can provide you with the
proper packing materials. UPS is usually the best way to ship the units. Heavy units should be “double-boxed”
for safe transport.
D. We also strongly recommend that you insure the equipment, since we cannot be responsible for loss of or dam-
age to equipment that you ship. Of course, we insure the equipment when we ship it back to you.
