Introduction
DSW (Digital Secure Wireless) is designed for no-compromise applications where performance and security
are the highest priority.
A completely new digital architecture was developed
for the DSW wireless system. Extended operating
range rivals the best analog and Digital Hybrid Wireless® systems, with remarkable audio quality and only
2.5 ms of latency. The system operates on standard
UHF FCC Part 74 frequencies (TV channel band).
256-bit encryption is applied to the transmitted signal
stream for security against eavesdropping. The algorithm conforms to the AES 256-CTR standard.
DR Modular Receiver
The DR receiver is a 1RU modular, six-channel design
with a host mainframe that contains the DSP, microprocessor, antenna multicoupler and control interface.
Receiver modules are installed on either side of the
mainframe. No tools are required to remove and install
the receiver modules. Each module will tune across a
25.6 MHz range.
Antenna ports on the rear panel accept input from
remote antennas, with a “loop-thru” output to another
mainframe. A high quality internal multicoupler distributes the RF signal to the receiver modules.
For rack mount installations, a kit is available to mount
antenna inputs (BNC connectors) on the receiver front
panel using a coaxial cable routed through the receiver
chassis to the rear panel connections.
DB Belt Pack Transmitter
The DB belt pack transmitter is encased in a solid
machined aluminum housing with a membrane switch
panel and backlit LCD interface. The servo bias input
circuitry will work with a wide variety of microphones
and line level sources, Input gain is adjustable over
a wide range in 1 dB steps to optimize the signal to
noise ratio and dynamics of the audio.
The transmitter tunes across the entire frequency
range of the DSW system, from 470 MHz to 691 MHz.

Hardware Installation
Receiver Modules
The DR mainframe/host assembly is a wideband
design that coves the entire available frequency range.
Individual receiver modules are available in 25.6 MHz
frequency “blocks.” Any module can be installed in any
of the six mainframe positions without regard to the
frequency tuning range. Module positions correspond
to the rear panel audio outputs as shown here.

Installing Receiver Modules
1. Turn the mainframe power off.
The receiver modules interface with the main as-
sembly through multi-pin connectors on either side
of the chassis. Insert the module straight down and
then slide it toward the main housing to insert the
connector pins. The module should sit flush against
the side of the housing.

Antenna Connections
Connect the antennas or coaxial cables to the antenna
input connectors labeled IN on the rear panel.
Note: The frequency bandwidth of the antennas
must cover the range of the modules in use.
For multiple unit installations, a “loop thru” is available
to feed two or three receivers from a single antenna
pair. Connect coaxial cables from the multicoupler outputs on the first receiver to the antenna inputs on the
next receiver in the stack.

Audio Output Wiring - AES3 Digital
XLR output connectors deliver digital audio that conforms to the AES standard. The wiring is the same as
a balanced analog output.
Pin 1 Ground/Shield
Pin 2 Data (+)
Pin 3 Data (–)
Pins 2 and 3 carry the digital audio. Although polarity
is not an issue, it is good practice to maintain a “pin
to pin” connection - pin 1 to pin 1, pin 2 to pin 2, pin 3
to pin 3 in cables that terminate in XLR connectors at
both ends. It is best to use 110 ohm cable designed to
carry digital signals. Conventional microphone cables
may cause problems, especially with distances over 30
or 40 feet.
For pinout details of wiring to a DB-25 connector, refer
to the documentation for the device you are using.
Channel assignments per connector are marked on
the rear panel of the receiver.

for different functions with this setup menu.
Rolloff - The low frequency audio rolloff is
adjustable to optimize performance for environmental conditions or personal preference.
Phase - The polarity of the audio signal can
be reversed to match other microphones in
the system. Differences in polarity are due to
microphone designs and connector wiring.
BatType - This setting makes the battery status display more accurate, since alkaline and
lithium batteries behave differently as they are
discharged.
BatTime - A built-in timer can be used with
any battery type, but it is especially valuable
with rechargeable batteries such as NiMH
types. The voltage remains fairly constant
across the discharge time of a rechargeable
battery, then drops quickly near the end of
the operating time. The most accurate way to
determine runtime status is by testing the time
provided by a particular battery brand and
type, then using a timer to determine remaining runtim.

Copying Transmitter Settings To and From
the Receiver
Connect the key cable from the jack labeled KEY on
the front of the receiver to the micro USB port on the
side of the transmitter.
If transmitter settings are defined in the receiver, they
can be transferred to a connected transmitter, or copied from a transmitter to a receiver channel using the
key cable.
Transmitter Settings Screen
Press MENU/SEL and navigate to the TX MENU, then
to the SEND SETTINGS (microphone) icon. Press the
encoder to enter the transmitter settings screen.
Get Settings from Transmitter
The settings in the transmitter can be transferred to the
receiver for storage or editing with the GET SET option
in the setup screen.
The transmitter must be turned fully on and tuned to
the selected channel on the receiver.
Select the desired channel and then the GET SET
option. Turn the transmitter fully on with the RF output
enabled and press the encoder to start the transfer.
An error message will appear if no RF signal is being
received.
NOTE: Settings will be displayed on the Transmitter
Settings screen, but changes are not made here.
Settings are adjusted in the TX MENU as described
on previous pages, on the transmitter itself, or with
the Wireless Designer software.
Select the desired channel with the CHOOSE TX option at the bottom of the screen.
Send Settings to Transmitter
After the channel is selected, highlight the SEND
SET option at the bottom of the screen. Connect the
transmitter with the USB cable and press the encoder

System Setup
These instructions apply to setup using the front panel
LCD. If you will be using Wireless Designer for setup,
instructions are in the help files supplied with the software.
Install Receiver Modules
Turn power off on the DR mainframe. Install the modules as needed. Any module can be installed in any
position in the mainframe assembly. When the power
is turned on, the modules will be detected during the
bootup sequence and an icon for each one will appear
on the LCD.
Generate Encryption Key
On the receiver LCD, navigate to the KEY MANAGEMENT item in the Top Menu and press the encoder to
enter the setup screen.
Select the NEW KEY option and press the encoder to
enter the setup screen.
NOTE: It is generally more convenient to use a
PERSISTENT key during setup, since power may
be need to be cycled on and off on the transmitters
or receiver until the system is completely set up.
The stored key can be deleted manually with the WIPE
KEY option.
In this setup screen, the type of encryption key policy
can be set, a new key generated or the existing key
can be deleted.
The encryption key policy can be configured as:
s 0%23)34%.4
s /.%4)-%+%9
A PERSISTENT key will remain in receiver and transmitter memory until it is replaced with a new key or
manually deleted using WIPE KEY in the menus.
A ONE-TIME ONLY key is used for maximum secu-
rity. The key exists only as long as the power on both
receiver and transmitter remains on during a single
session. If a transmitter is powered off, but the receiver
has remained turned on, the key must be sent to the
transmitter again. If the power is turned off on the
receiver, the entire session concludes and a new key
must be generated and sent to all transmitters.
In either key policy, there are 256 “instances” available
each time a new key is generated. “Instance” refers to
a transfer of the key from receiver to transmitter. Each
instance contains a unique key. The number of instances is reduced each time a key is transferred. When
the number of instances reaches 10, a warning will be
displayed on the LCD.
Initial Transmitter Setup
Attach the antenna and install the batteries into the
transmitters that will be used. Turn the power on and
observe the BATT LED on the transmitter. Verify that
the batteries are fresh or fully charged (the LED will
glow green with good batteries).
Transfer Encryption Key to Transmitters
On the receiver LCD, navigate to the KEY TRANSFER
item in the Top Menu and press the encoder to enter
the setup screen.
YES indicates the transmitter is connected
Connect the transmitter with the key cable and press
the encoder to start the transfer. The LED on the top
right corner of the keypad will glow blue when the key
has been transferred successfully.
NOTE: The key can be transferred with the
transmitter either fully powered up or in the standby
mode with the RF output turned off.

Frequency Selection
Manual selection may be necessary if frequencies are
mandated by an authority, such as a major sporting
event. You can manually set the frequencies and settings for the transmitters in the receiver, then connect
a transmitter and transfer settings. Or, of course, just
manually set the frequency in each receiver channel
and transmitter.
Using Smart TuneTM is the easiest way to find and
set good operating frequencies. The process scans
the tuning range of designated channels, identifies a
good operating frequency and prompts the operator
to connect a transmitter and transfer the settings. The
transfer can be completed or skipped, and scanning
will then continue with the next receiver.
Manual Frequency Selection
From the Main Window, press the numbered channel
select button under the LCD on the front panel to open
the receiver setup screen. Rotate the encoder to select
the EDIT option.
DSW Digital Wireless System
After adjusting the frequency, press the BACK button on the front panel or the encoder to de-highlight
the item. Then press the BACK button to leave the
EDIT option. Use the SEL RX option or return to the
Main Window to move to another receiver to adjust its
frequency.
Selected receiver
Select the SEL RX option
and press the encoder
Press the encoder to de-highlight SEL RX. Select the
EDIT option and repeat the above procedure.
Using Smart TuneTM for Frequency Selection
When new frequencies must be discovered, this automatic frequency scanning and setup function is by far
the easiest and quickest way to get up and running.
Select the SMART TUNE item in the Top Menu and
press the encoder to open the setup screen.
Press the encoder to highlight the EDIT option and
then rotate the encoder to select the left or right hand
frequency item. The left hand item adjusts frequency in
1 MHz steps, and the right hand item adjusts frequency in 25 kHz steps.
Selected item is indicated with
ruled lines above and below
Press the encoder to highlight the selected item and
then rotate it to set the frequency. Then press the
encoder to de-highlight it, rotate the encoder to select
the other frequency item and press the encoder to
highlight it.
A check box next to each receiver indicates whether
or not the channel will be included in the scanning and
setup process. Press the channel select buttons on
the keypad below the LCD to check or uncheck each
channel. Normally, a single scan on each channel is
adequate to identify good operating frequencies. If
you prefer, up to 10 scans can be performed on each
frequency. Select the number of scans with the NUM
SCAN PASS option.
Selects the number of scans on each channel
Adjust in 1 MHz steps
Rio Rancho, NM
Adjust in 25 kHz steps

DSW Digital Wireless System
Select BEGIN in the setup screen and press the encoder to start the process. Scanning will proceed one
at a time on each receiver, from the lowest numbered
one to the next higher numbered one.
Each scan pass takes about 20 seconds. After the
scan on the first receiver is completed, the receiver
will be set to the newly identified frequency. A message will appear on the LCD, prompting to connect a
transmitter and transfer the settings from the receiver.
To set up the transmitter, turn its power on, connect it
with the USB cable, select SEND TX SET and press
the encoder to start the transfer.
Transmitter setup can also be skipped at this time and
set up later.
NOTE: It is best to set up transmitters when
prompted, and leave them turned on for subsequent
scans, so their signals will be included in finding
clear spectrum for new frequencies.
Navigate to the TX MENU on the receiver and select
the desired channel. Connect a transmitter to the
receiver with the USB cable. Select the SEND SET option at the bottom of the screen and press the encoder.
Attach Microphone and Adjust Transmitter Gain
This adjustment is very important to optimize the signal to noise ratio and dynamic range that the system is
capable of delivering.
It is best to go through the following procedure with the
transmitter in the standby mode so that no audio will
enter the sound system or recorder during adjustment.
1) With fresh batteries in the transmitter, power the unit
on in the standby mode (see previous section Pow-
ering On in Standby Mode).
2) Navigate to the Gain setup screen.

3) Position a microphone the way it will be used in
actual operation and have the user speak or sing at
the loudest level that will occur during use, or set the
output level of the instrument or audio device to the
maximum level that will be used.
4) Use the
until the peak indicator on the audio level display
flickers during loud audio passages.
NOTE: The peak indicator does not mean the audio
is distorted. It simply means full modulation has
been achieved. The input limit will cleanly handle
increased levels up to 30 dB above this point.
5) Once the audio gain has been set, the signal can
be sent through the sound system for overall level
adjustments, monitor settings, etc.
6) Always leave the transmitter gain adjustment set
according to these instructions. Adjustment only
needs to be made if a different person, microphone,
microphone placement, or a different instrument is
used. Do not change it to adjust the audio output
level of the receiver. If the audio output level of the
receiver is too high or low, use only the controls on
the receiver to make that adjustment.

LECTROSONICS, INC.
Adjust Receiver Analog Audio Output Level
The analog audio output of the receiver is set at maximum, and lower levels are achieved with an attenuator
to reduce the signal level to match the level requirements of other equipment. This means that there is no
difference in signal to noise ratio regardless of where
the receiver output level control is set.
Any time gain is applied to the audio signal, noise
is also added. The best approach is to use as much
output on the receiver as possible with the least
amount of gain on the connected device. Following this
principle, it is generally best to use a line input on the
connected device to avoid additional gain that might be
applied to a microphone input.
A tone generator is provided in the receiver to allow accurate input level adjustment of the connected
device. This steady tone is the same as the maximum
level that will appear at the outputs. The outputs can
be set between -35 dBu and +8 dBu, in 1 dB steps.
For example, if a channel is set at +0, the maximum
output that will appear at that output is +0 dBu when
the transmitter is driven to full modulation (the onset of
limiting).
DSW Digital Wireless System
NOTE: If the transmitter is driven hard into limiting,
up to 30 dB, the output level of the receiver will be a
few dB above this nominal level.
Once the input level on the connected device is set,
turn the tone generator off in the menu. The generator
will turn off automatically when you return to the Main
Window.
When the receiver output and connected device input
are set up in this manner, there is no need to change
these settings from one event to another. As microphones and microphone placement change, and with
different voices, the only adjustment needed is the
input gain on the transmitter.
The simple and accurate way to match the receiver
output with the input of the connected device is using
the following procedure.
1) Turn the output of the DR receiver all the down (-35
but not OFF).
2) Turn the input of the connected device all the way
down, but not OFF.
3) Turn the tone on and gradually increase the output
level of the receiver while observing the input level
meter on the connected device. Increase the level
until the input level meter indicates full scale.

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 email 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.
