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® 2000 or Windows®XP

computer system. 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 external devices using either the USB or

RS232 serial port.

DM84 Installation Guide

LECTROSONICS, INC.6

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. The DM84 has an internal

switching power supply that can tolerate voltages

ranging from 90 VAC to 240 VAC. Use an approved

power cable for installations outside North America.

Cables

It is recommended 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

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 ex-

posed, then tighten the retaining screw.

Caution: Do not over tighten the retaining

screw.

Note the labeling on the DM84 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 DM84 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 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 DM84. The shield or negative (–) output

should be connected the DM84’s negative (–) input.

Two wire cables should have a jumper between the

DM84 negative input and ground. Three wire cables

should have the shield connected to the DM84’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 DM84 input (3-Wire). (See illustra-

tion.) When connecting balanced sources to the DM84,

it is important 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

situation.

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, and

include an attenuator to reduce the signal to mic level.

NOTE: Using a Line Output with digital attenuation

applied with the Control Panel to achieve Mic Level

will result in added noise.

When the DM84 output is connected to a balanced

input, wire it as indicated in DM84 Out to Balanced

Input (3-Wire). Select Mic or Line (as appropriate) via

the software GUI.

When the DM84 output is conencted to an unbalanced

input, wire it as indicated in DM84 Out to Unbalanced

Input (3-Wire), or DM84 Out to Unbalanced Input (2-

Wire).

Phantom Power

The DM84 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

minimum 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

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 Programmable Inputs control tab in the Control

Panel GUI. See the Programmable Input tab in the

Control Panel software Help for setting all program-

mable input parameters.

Programmable Outputs

Programmable outputs are used to indicate channel

activity or the current state of a programmable input or

some other feature of the DM84. 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 Inputs and Outputs

Wiring Diagram Example

DM84 Rear Panel

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.

Configuring a unit as a Master or a Slave can be done

using 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 Inter-

face 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 Control Panel GUI interface is used to do this.

DM84 Installation Guide

Rio Rancho, NM 11

Installing LecNet2™Software and USB Driver

LecNet2™ is a Graphic User Interface (GUI) designed

to allow easy setup and monitoring of DM84 compo-

nents using Windows®2000 or XP computer systems.

LecNet2™ includes the necessary Control Panels to

configure and monitor all the DM84 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

WIndows 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

LecNet2 software.

Installing the LecNet2™USB Driver

There are two methods of connecting a Windows®-

based computer system to the DM84 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 DM84 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 DM84 is connected to a Windows XP com-

puter system for the very first time, the Windows®"New

Hardware 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 proce-

dure 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

Install from a list or specific location (Ad-

vanced) and click Next> to continue.

3. Select "Search for the best driver in these

locations", 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

warning you that the driver has not passed Win-

dows Logo Testing, click Continue Anyway.

DM84 Installation Guide

LECTROSONICS, INC.12

5. When the driver installation is complete, the final

page of the Wizard appears. Click Finish to

complete the LecNet2™ USB driver installation.

Installation of Additional Units

(or LecNet 2™ devices)

The Windows XP operating system regards all

Lecnet2™ 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 Lec-

Net2™ USB driver has already been installed at least

once before on the computer system, the process is

simplified because 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

Testing. 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.

Use the following procedure to install the LecNet2™

USB driver using the Wizard.

1. Connect a cable between the DM84 processor USB

port and the computer system . Place the

LecNet2™ Installation Disk in the computer

system’s CD-ROM drive and click Next> to con-

tinue.

2. Select "Search for a suitable driver for my

device (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.

DM84 Installation Guide

LECTROSONICS, INC.14

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.

1) Connect the computer system to the DM84 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 DM84 unit at a time can be

connected to a serial port using the RS-232 cable.

Multiple units may be connected to a USB port

using a USB hub.

2) Turn the computer system on. After the boot

sequence is complete, click Start, then All Pro-

grams.

3) Select LecNet2, then select the DM84 control

panel from the list.

5) If the “Just a Reminder” dialog appears, click OK

to continue.

6) Click Connection on the Main Menu bar, then

select the type of connection between the computer

system or external control system and the DM84

unit. The choices are:

USB - used when the computer is connected

to the DM84 unit via the front or rear

panel USB port.

Network - One or more DM84 devices may be

made available for network connections

by connecting them to a gateway server

acting as a middleman, receiving

commands for a DM84 over a network

connection, and forwarding them to the

DM84 device connected via USB.

Extron IPL T S - One or more DM84 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

DM84 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 DM84 and

the computer sytsem, or for connecting

the DM84 to an external control system

such as those made by Crestron®or

AMX®.

NOTE: The menu will list all serial ports detected

on the PC. However, many newer PCs have no

RS232 serial ports at all, so no serial connection

options will be listed.

Go Offline - No Connection Made, this mode

can be used for off line configuration and

is the default mode.

Connect Menu

DM84 Installation Guide

Rio Rancho, NM 15

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.

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 3 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.

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.

Inputs Matrix Outputs

IMPORTANT: Any changes made during setup

must be saved in the unit via the preset menu.

For direct support from the factory, call 1-800-821-1121

Ask for anyone in the SALES department. They will be

able to answer your setup and/or technical questions or

will get the correct person who can help on the phone.

Front Panel Gain Controls

The gain of input and output audio channels is adjust-

able from the front panel of the DM84. This feature is

useful for system setup and adjustment, and may be left

enabled to allow users to “touch up” gains as needed

during operation.

Gain can be increased or decreased within a range which

is centered around 0 dB (unity) gain. The minimum gain

position has a special meaning - the channel will be

turned “off” when the control is rotated to the fully counter-

clockwise position. The range of adjustment for each

channel is individually programmable using the Control

Panel GUI (in Device Setup Menu) or LecNet2 serial

commands. Changes made to the gain range settings

take effect immediately and are global in scope - the

same settings are in effect no matter what memory

“preset” is loaded. The default range is 30 dB (+/- 15

dB).

Any or all of the front panel gain controls may be

“locked out” to prevent unauthorized changes to the

system. This is also done using the Control Panel GUI

(in Device Setup Menu) or LecNet2 serial commands.

Changes made to the gain control lock settings

take effect immediately and are global in scope -

the same settings are in effect no matter what

memory “preset” is loaded.

NOTE: When the Front Panel Mute feature is

enabled, the minimum gain position has a special

meaning. The channel will be muted and the

associated activity indicator will blink RED to warn

the user that no audio is being passed. This

feature can be controlled using the supplied GUI

control panel or the serial command “fpmten.”

Front Panel Input/Output Activity Indicators

These indicators reflect activity on input and output

audio channels. Useful for setup and troubleshooting,

these tri-color LEDs are interpreted as follows:

1) Input channels

DARK - channel is inactive

GREEN - audio present (level greater than -35 dBu)

ORANGE - input compressor is active

RED - input is in clipping (overdriven)

BLINKING RED - input has been turned off using

front panel gain control

2) Output channels

DARK - channel is inactive

GREEN - audio present (level greater than -35 dBu)

ORANGE - output compressor is active

RED - output is in limiting

BLINKING RED - output has been turned off using

front panel gain control
