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.
