DPR-A
General Technical
Description
The Lectrosonics DPR-A digital plug-On transmitter
benefits from a fourth generation design with specially
developed, high efficiency digital circuitry for extended
operating time on two AA batteries. The unique design
provides several distinct features for professional applications:
• Outstanding UHF operating range
• Superb audio quality
• On board recording
• Corrosion-resistant housing
The transmitter uses a standard 3-pin XLR input jack
for use with any microphone with a mating XLR connector. An LCD, membrane switches and multi-color
LEDs on the control panel make input gain adjustments and frequency selection quick and accurate,
without having to view the receiver. The housing is
machined from a solid aluminum block to provide a
lightweight and rugged package. A special non-corrosive finish resists salt water exposure and perspiration
in extreme environments.
The DSP controlled input limiter features a wide range
dual envelope design which cleanly limits input signal
peaks over 30 dB above full modulation. Switching
power supplies provide constant voltages to the transmitter circuits from the beginning (3 Volts) to the end
(1.7 Volts) of battery life, and an ultra low noise input
amplifier for quiet operation.
The DPR-A has an external SMA antenna jack, which
accepts Lectrosonics steel flex wire AMM or AMJ
series antennas.
Low Frequency Roll-Off
The low frequency roll-off can be set for a 3 dB down
point at 25, 35, 50, 70, 100, 120 and 150 Hz to control subsonic and very low frequency audio content in
the audio. The actual roll-off frequency will vary slightly
depending upon the low frequency response of the
microphone.
Excessive low frequency content can drive the transmitter into limiting, or in the case of high level sound
systems, even cause damage to loudspeaker systems.
The roll-off is normally adjusted by ear while listening
as the system is operating.
Input Limiter
A DSP-controlled analog audio limiter is employed
before the analog-to-digital (A-D) converter. The limiter
has a range of more than 30 dB for excellent overload
protection. A dual release envelope makes the limiter
acoustically transparent while maintaining low distortion. It can be thought of as two limiters in series, a
fast attack and release limiter followed by a slow attack
and release limiter. The limiter recovers quickly from
brief transients, with no audible side effects, and also
recovers slowly from sustained high levels, to keep
audio distortion low and while preserving short term
dynamics.
Control Panel
The control panel includes five membrane switches and
an LCD screen to adjust the operational settings. Multicolor LEDs are used to indicate audio signal levels for
accurate gain adjustment, battery status and encryption key function.
Alternate Recording Function
The DPR has a built in recording function for use in
situations where RF may not be possible or to work as
a stand alone recorder. The record function and transmit functions are exclusive of each other - you cannot
record AND transmit at the same time. When the unit
is transmitting and recording is turned on, the audio in
the RF transmission will stop, but the battery status will
still be sent to the receiver.
The recorder samples at 48 kHz rate with a 24 bit
sample depth. The micro SDHC card also offers easy
firmware update capabilities without the need for a
USB cable or driver issues.
Encryption
When transmitting audio, there are situations where
privacy is essential, such as during professional sporting events, in court rooms or private meetings. For
instances where your audio transmission needs to be
kept secure, without sacrificing audio quality, Lectrosonics implements AES256 encryption in our digital
wireless microphone systems. High entropy encryption keys are first created by a Lectrosonics receiver
such as the DSQD Receiver. The key is then synced
with the DPR via the IR port. The transmission will be
encrypted and can only be decoded if the receiver
and transmitter have matching encryption keys. If you
are trying to transmit an audio signal and keys do not
match, all that will be heard is silence.

LCD Screen
The LCD is a numeric-type Liquid Crystal Display with
several screens that allow settings to be made with
the MENU/SEL and BACK buttons, and the UP and
DOWN arrow buttons to configure the transmitter. The
transmitter can be turned on in a “standby” mode with
the carrier turned off to make adjustments without the
risk of interfering with other wireless systems nearby.
Power LED
The PWR LED glows green when the batteries are
charged. The color changes to red when there is about
20 minutes of life left. When the LED begins to blink
red, there are only a few minutes of life.
A weak battery will sometimes cause the PWR LED to
glow green immediately after being put into the unit,
but will soon discharge to the point where the LED will
go red or shut off completely.
Key LED
The blue Key LED will blink if an encryption key is not
set and “no key” will blink on LCD. The Key LED will
remain on if the encryption is set correctly and will turn
off in Standby mode.
Modulation LEDs
The Modulation LEDs provide a visual indication of the
input audio signal level from the microphone. These
two bicolor LEDs can glow either red or green to indicate modulation levels. Full modulation (0 dB) occurs
when the -20 LED first turns red.

Battery Installation
The battery compartment door is made of machined
aluminum and is hinged to the housing to prevent it being damaged or lost.
The transmitter is powered by two AA batteries.
Note: Standard zinc-carbon batteries marked
“heavy-duty” or “long-lasting” are not adequate.
To install new batteries:
1. Slide open the Battery Cover and remove any old
batteries.
2. Insert the new batteries into the housing. One battery goes in positive (+) end first, the other negative
(- ) end first. Look into the battery compartment to
determine which end goes in which side. The side
with the circular insulator is the side which accepts
the positive end of the battery.
Attaching/Removing a
Microphone
The spring loaded coupler under the XLR jack maintains a secure fit to the microphone jack with continuous pressure applied by an internal spring.
To attach the microphone, simply align the XLR pins
and press the microphone onto the transmitter until
the coupler retracts and latches. A click sound will be
heard as the connector latches.
To remove the microphone, hold the transmitter body
in one hand with the microphone pointing upward. Use
your other hand to rotate the coupler until the latch
releases and the coupler rises slightly.
Do not pull on the microphone while releasing the
locking collar.

Formatting SD Card
New microSDHC memory cards come pre-formatted
with a FAT32 file system which is optimized for good
performance. The DPR relies on this performance and
will never disturb the underlying low level formatting of
the SD card. When the DPR “formats” a card, it performs a function similar to the Windows “Quick Format”
which deletes all files and prepares the card for recording. The card can be read by any standard computer
but if any write, edit or deletions are made to the card
by the computer, the card must be re-formatted with the
DPR to prepare it again for recording. The DPR never
low level formats a card and we strongly advise against
doing so with the computer.
To format the card with the DPR, select Format Card in
the menu and press MENU/SEL on the keypad.
NOTE: An error message will appear if samples
are lost due to a poor performing “slow” card.
WARNING: Do not perform a low level format (complete format) with a computer. Doing so may render the
memory card unusable with the DPR recorder.
With a windows based computer, be sure to check the
quick format box before formatting the card.
With a Mac, choose MS-DOS (FAT).

IMPORTANT
The formatting of the SD card sets up contiguous
sectors for maximum efficiency in the recording
process. The file format utilizes the BEXT (Broadcast
Extension) wave format which has sufficient data
space in the header for the file information and the
time code imprint.
The SD card, as formatted by the DPR recorder, can
be corrupted by any attempt to directly edit, change,
format or view the files on a computer.
The simplest way to prevent data corruption is to copy
the .wav files from the card to a computer or other
Windows or OS formatted media FIRST. Repeat –
COPY THE FILES FIRST!
Do not rename files directly on the SD card.
Do not attempt to edit the files directly on the SD
card.
Do not save ANYTHING to the SD card with a
computer (such as the take log, note files etc) - it is
formatted for DPR recorder use only.
Do not open the files on the SD card with any third
party program such as Wave Agent or Audacity and
permit a save. In Wave Agent, do not IMPORT - you
can OPEN and play it but do not save or Import Wave Agent will corrupt the file.
In short - there should be NO manipulation of the
data on the card or addition of data to the card with
anything other than an DPR recorder. Copy the files
to a computer, thumb drive, hard drive, etc. that has
been formatted as a regular OS device FIRST - then
you can edit freely.
iXML HEADER SUPPORT
Recordings contain industry standard iXML chunks in
the file headers, with the most commonly used fields
filled in.
Compatibility with
microSDHC memory cards
Please note that the DPR is designed for use with
microSDHC memory cards. There are several types
of SD card standards (as of this writing) based on
capacity (storage in GB).
SDSC: standard capacity, up to and including 2 GB –
DO NOT USE!
SDHC: high capacity, more than 2 GB and up to and
including 32 GB – USE THIS TYPE.
SDXC: extended capacity, more than 32 GB and up to
and including 2 TB – DO NOT USE!
SDUC: extended capacity, more than 2TB and up to
and including 128 TB – DO NOT USE!
The larger XC and UC cards use a different formatting method and bus structure and are NOT compatible with the recorder. These are typically used with
later generation video systems and cameras for
image applications (video and high resolution, high
speed photography).
ONLY microSDHC memory cards should be used.
They are available in capacities from 4GB to 32GB.
Look for the Speed Class 10 cards (as indicated by
a C wrapped around the number 10), or the UHS
Speed Class I cards (as indicated by the numeral 1
inside a U symbol). Also note the microSDHC Logo.
If you are switching to a new brand or source of card,
we always suggest testing first before using the card
on a critical application.
The following markings will appear on compatible
memory cards. One or all of the markings will appear
on the card housing and the packaging.

Helpful Features on Receivers
To aid in finding clear frequencies, several Lectrosonics receivers offer a SmartTune feature that scans the
tuning range of the receiver and displays a graphical
report that shows where RF signals are present at
different levels, and areas where there is little or no
RF energy present. The software then automatically
selects the best channel for operation.
Lectrosonics receivers equipped with an IR Sync function allow the receiver to set frequency on the transmitter via an infrared link between the two units.

Adjusting the Input Gain
The two bicolor Modulation LEDs on the control panel
provide a visual indication of the audio signal level
entering the transmitter. The LEDs will glow either red
or green to indicate modulation levels as shown in the
following table.
Signal Level -20 LED -10 LED
Less than -20 dB
-20 dB to -10 dB
-10 dB to +0 dB
+0 dB to +10 dB
Greater than +10 dB
NOTE: Full modulation is achieved at 0 dB,
when the “-20” LED first turns red. The limiter
can cleanly handle peaks up to 30 dB above this
point.
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
Turning Power ON and OFF).
2) Navigate to the Gain setup screen.

3) Prepare the signal source. 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 and arrow buttons to adjust the gain
until the –10 dB glows green and the –20 dB LED
starts to flicker red during the loudest peaks in the
audio.
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) If the audio output level of the receiver is too high
or low, use only the controls on the receiver to
make adjustments. Always leave the transmitter
gain adjustment set according to these instructions, and do not change it to adjust the audio
output level of the receiver.
NOTE: Input Gain may also be accessed by
holding down MENU/SEL from the home/main
screen.

Selecting the Low Frequency Roll-off
It is possible that the low frequency roll-off point could
affect the gain setting, so it’s generally good practice to
make this adjustment before adjusting the input gain.
The point at which the roll-off takes place can be set
to:
• 25 Hz • 100 Hz
• 35 Hz • 120 Hz
• 50 Hz • 150 Hz
• 70 Hz
The roll-off is often adjusted by ear while monitoring
the audio.

15V
About the Phantom Power Supply
Three phantom voltages are selectable from the control panel. The voltages are:
• 5 Volts for lavaliere microphones,
• 15 Volts for some professional mics requiring high
current and for many common stage mics that will
operate over a wide phantom Voltage range of 12
to 48 Volts. With the proper adapter, this position
can also be used with T power microphones. See
our web site for details on finding or making the
proper adapter.
• 48 Volts for microphones that do in fact require
a supply greater than 18 Volts. (See below for a
discussion of why 42 and not a “true” 48 Volts.)
For longest battery life use the minimum phantom
voltage necessary for the microphone. Many stage
microphones regulate the 48 Volts down to 10 Volts
internally anyway, so you might as well use the 15 Volt
setting and save some battery power. If you are not
using a microphone for the input device, or are using a
microphone that does not require phantom power, turn
the phantom power off.
Phantom power should only be used with a fully floating, balanced device, such as common microphones
with a 3-pin XLR connector. If you use the phantom
power with an unbalanced device or if pins 2 or 3 are
DC connected to ground, then you will draw maximum current from the power supply. The DPR is fully
protected against such shorts but the batteries will be
drained at twice the normal rate.
The transmitter can supply 4 mA at 42 Volts, 8 mA at
15 Volts, and 8 mA at 5 Volts. The 42 Volts setting actually supplies the same voltage to a 48 Volt microphone
as the DIN standard arrangement due to a dynamic
biasing scheme that does not have as much voltage
drop as the DIN standard. The 48 Volt DIN standard
arrangement protects against shorts and high fault
current with high resistance in the power supply feeds
to pins 2 and 3. This provides protection if the supply current is accidentally shorted to ground and also
keeps the microphone from being attenuated by the
power supply.
The DPR improves on those functions and is able to
use less power from the battery by using constant
current sources and current limiters. With this dynamic
arrangement, the DPR can also supply more than
twice the current of competing 48 Volt plug on units
and provide four times the current for some very high
end 15 Volt microphones.

DPR-A
Key Menu
KeyType
The DPR receives an encryption key via the IR port
from a key generating receiver (such as the Lectrosonics DCHR and DSQD receivers). Begin by selecting
a key type in the receiver and generating a new key.
Set the matching KEY TYPE in the DPR and transfer
the key from the receiver (SYNC KEY) to the DPR via
the IR ports. A confirmation message will display on
the receiver display if the transfer is successful. The
transmitted audio will then be encrypted and can only
be decoded if the receiver has the matching encryption
key.
The DPR has three options for encryption keys:
• Universal: This is the most convenient encryption option available. All encryption-capable
Lectrosonics transmitters and receivers contain
the Universal Key. The key does not have to be
generated by a receiver. Simply set the DPR and a
Lecrosonics receiver to Universal, and the encryption is in place. This allows for convenient encryption amongst multiple transmitters and receivers,
but not as secure as creating a unique key.
• Shared: There are an unlimited number of
shared keys available. Once generated by a receiver and transferred to the DPR, the encryption
key is available to be shared (synced) by the DPR
with other transmitters/receivers via the IR port.
When a transmitter is set to this key type, a menu
item named SEND KEY is available to transfer the
key to another device.
• Standard: This is the highest level of security.
The encryption keys are unique to the receiver and
there are only 256 keys available to be transferred
to a transmitter. The receiver tracks the number of
keys generated and the number of times each key
is transferred.

Setting Battery Timer
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 the timer to determine remaining runtime. Rechargeable batteries lose capacity
over their life, so it is good to run the battery down and
note the runtime on older or unfamiliar batteries.

LectroRM
By New Endian LLC
LectroRM is a mobile application for iOS and Android
operating systems. Its purpose is to remotely control
Lectrosonics Transmitters, including:
• SM Series
• WM
• L Series
• DPR
The app remotely changes settings on the transmitter through the use of encoded audio tones, which
when received by the attached microphone, will alter
the configured setting. The app was released by New
Endian, LLC in September 2011. The app is available
for download and sells for $25 on the Apple App Store
and Google Play Store.
LectroRM’s remote control mechanism is the use of an
audio sequence of tones (dweedles) that are interpreted by the transmitter as a configuration change. The
settings available in LectroRM are:
• Audio Level
• Frequency
• Sleep Mode
• Lock Mode
User Interface
The user interface involves selecting the audio sequence related to the desired change. Each version
has an interface for selecting the desired setting and
the desired option for that setting. Each version also
has a mechanism to prevent accidental activation of
the tone.
iOS
Android
The Android version keeps all settings on the same
page and allows the user to toggle between the
activation buttons for each setting. The activation
button must be long pressed to activate. The Android
version also allows users to keep a configurable list of
full sets of settings.
Activation
For a transmitter to respond to remote control audio
tones, the transmitter must meet certain requirements:
• The transmitter must not be turned off; it can
however be in sleep mode.
• The transmitter microphone must be
within range.
• The transmitter must be configured to enable
remote control activation.
Please be aware this app is not a
Lectrosonics product. It is privately owned
and operated by New Endian LLC,
www.newendian.com.
The iPhone version keeps each available setting on a
separate page with the list of options for that setting.
On iOS, the “Activate” toggle switch must be enabled
to show the button which will then activate the audio.
The iOS version’s default orientation is upside-down
but can be configured to orient right-side up. The
purpose for this is to orient the device’s speaker, which
is at the bottom of the device, closer to the transmitter
microphone.

Firmware Update
Firmware updates are made using a microSDHC
memory card. Download and copy the following firmware update files to a drive on your computer.
• dprMXXX.hex is the microcontroller file, where
“XXX” is the revision number.
• dprFXXX.mcs is the FPGA file, where “XXX” is
the revision number.
In the computer:
1) Perform a Quick Format of the card. On a Windows-based system, this will automatically format
the card to the FAT32 format, which is the Windows
standard. On a Mac, you may be given several
options. If the card is already formatted in Windows (FAT32) - it will be greyed out - then you do
not need to do anything. If the card is in another
format, choose Windows (FAT32) and then click
“Erase”. When the quick format on the computer is
complete, close the dialogue box and open the file
browser.
2) Copy the dpr vX_xx.ldr file to the memory card,
then safely eject the card from the computer.
In the DPR:
1) Leave the DPR turned off and insert the microSDHC memory card into the slot.
2) Hold down both the UP and DOWN arrow buttons
on the control panel and turn the power on.
3) The transmitter will boot up into the firmware update mode with the following options on the LCD:
• Update - Displays a scrollable list of the .ldr files
on the card.
• Power Off - Exits the update mode and turns the
power off.
Digital Plug-On Transmitter
7) If you re-insert the update card and turn the power back on for normal use, the LCD will display a
message prompting you to format the card:
Format Card?
(files lost)
• No
• Yes
If you wish to record audio on the card, you must
re-format it. Select Yes and press MENU/SEL to
format the card. When the process is complete,
the LCD will return to the Main Window and be
ready for normal operation.
If you choose to keep the card as is, you may
remove the card at this time.
The firmware update process is managed by a bootloader program - on very rare occasions, you might
need to update the bootloader.
WARNING: Updating the bootloader can
corrupt your unit if interrupted. Don’t update
the bootloader unless advised to do so by
the factory.
• dprbootX.hex is the bootloader file, where “X”
is the revision number.
Follow the same process as with a firmware update
and select the dprboot file.
NOTE: If the unit screen shows FORMAT CARD?,
power the unit off and repeat step 2. You were not
properly pressing UP, DOWN and POWER at the
same time.
4) Use the arrow buttons to select Update. Use the
UP and DOWN arrow buttons to select the desired
file and press MENU/SEL to install the firmware.
The LCD will display status messages while the
firmware is being updated.
5) When the update is complete, the LCD will display
this message: UPDATE SUCCESSFUL REMOVE
CARD. Open the battery door and remove the
memory card.
6) Re-attach the battery door and power the unit back
on. Verify that the firmware version was updated by
opening the Top Menu and navigating to ABOUT.

Recovery Process
In the event of a battery failure while the unit is recording, a recovery process is available to restore
the recording in proper format. When a new battery is
installed and the unit is turned back on, the recorder
will detect the missing data and prompt you to run the
recovery process. The file must be recovered or the
card will not be usable in the DPR.
First it will read:
Interrupted Recording
Found
The LCD message will ask:
Recover?
for safe use
see manual
You will have the choice of No or Yes (No is selected
as the default). If you wish to recover the file, use the
DOWN arrow button to select Yes, then press MENU/
SEL.
The next window will give you the option to recover all
or part of the file. The default times shown are the best
guess by the processor where the file stopped recording. The hours will be highlighted and you can either
accept the value shown or select a longer or shorter
time. If you are unsure, simply accept the value shown
as the default.
Press MENU/SEL and the minutes are then highlighted.
You can increase or decrease the time to be recovered.
In most cases you can simply accept the values shown
and the file will be recovered. After you have made your
time choices, press MENU/SEL again. A small GO!
symbol will appear next to the DOWN arrow button.
Pressing the button will initiate the file recovery. The
recovery will happen quickly and you will see:
Recovery
Successful
Special Note:
Files under 4 minutes long may recover with additional
data “tacked on” to the end of the file (from previous
recordings or data if the card had been used previously). This can be effectively eliminated in post with a
simple delete of the unwanted extra “noise” at the end
of the clip. The minimum recovered length will be one
minute. For example, if the recording is only 20 seconds
long, and you have selected one minute there will be
the desired 20 recorded seconds with an additional 40
seconds of other data and or artifacts in the file. If you
are uncertain about the length of the recording you can
save a longer file - there will simply be more “junk” at
the end of the clip. This “junk” may include audio data
recorded in earlier sessions that were discarded. This
“extra” information can be easily deleted in post production editing software at a later time.

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.
