DPR
Bias Voltage
Thank you for selecting a Lectrosonics DPR plug-On transmitter. The unique design provides several distinct features for professional applications:
• Outstanding UHF operating range
• Superb audio quality
• On board recording
• Corrosion-resistant housing
The Digital Hybrid Wireless® design (US Patent 7,225,135) combines 24-bit digital audio with analog FM resulting in a system that has the same operating range as analog systems, the same spectral efficiency as analog systems, the same long battery life as ana­log systems, plus the excellent audio fidelity typical of pure digital systems.
General Technical Description
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 DPR transmitter uses ±75 kHz wide deviation for an excellent signal to noise ratio and wide dynamic range. 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 trans-
mitter 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.
Digital Hybrid Wireless® Technology
All wireless links suffer from channel noise to some de­gree, and all wireless microphone systems seek to mini­mize the impact of that noise on the desired signal. Con­ventional analog systems use compandors for enhanced dynamic range, at the cost of subtle artifacts (known as “pumping” and “breathing”). Wholly digital systems defeat the noise by sending the audio information in digital form, at the cost of some combination of power, bandwidth and resistance to interference.
Lectrosonics Digital Hybrid Wireless® systems over­come channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded informa­tion via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor but a technique that can be accomplished only in the digital domain, even though the inputs and outputs are analog.
Channel noise still impacts received signal quality and will eventually overwhelm a receiver. Digital Hybrid Wireless® simply encodes the signal to use a noisy channel as efficiently and robustly as possible, yield­ing audio performance that rivals that of wholly digital systems, without the power and bandwidth problems inherent in digital transmission.
Because it uses an analog FM link, Digital Hybrid Wireless® enjoys all the benefits of conventional FM wireless systems, such as excellent range, efficient use of RF spectrum, and resistance to interference. However, unlike conventional FM systems, it does away with the analog compandor and its artifacts.

Digital Hybrid® Plug-On Transmitter
Outstanding Audio Performance
The audio performance of the overall hybrid system is depicted in the graph below. Distortion in the system is extremely low over the entire audio bandwidth.
No Pre-Emphasis/De-Emphasis
The Digital Hybrid Wireless® design results in a signal-to­noise ratio high enough to preclude the need for con­ventional pre-emphasis (HF boost) in the transmitter and de-emphasis (HF roll-off) in the receiver. This eliminates the potential for distortion on signals with abundant high-frequency information.
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 44.1kHz rate with a 24 bit sample depth. (the rate was selected due to the re­quired 44.1kHz rate used for the digital hybrid algo­rithm). 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 introduces Encryption Keys. Truly entro­pic 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 audio will be encrypted and can only be listened to if both DPR and receiver have the matching encryption key. If you are trying to transmit an audio signal and keys do not match, all that will be heard is silence or white noise.
Signal Encoding and Pilot Tone
In addition to controlling the limiter, the DSP also encodes the digitized audio from the A-D converter and adds an ultrasonic pilot tone to control the re­ceiver’s squelch. A pilot tone squelch system provides a reliable method of keeping a receiver output muted (squelched) even in the presence of significant interfer­ence.

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.

Audio Input Jack
The XLR input jack on the transmitter accommodates hand-held, shotgun and measurement microphones. Phantom power can be set at various levels for use with a wide variety of electret microphones.
Antenna
An antenna is formed between the housing and the attached microphone, operating much like a dipole. At UHF frequencies the length of the housing is similar to 1/4 wavelength of the operating frequency, so the an­tenna is surprisingly efficient, which helps extend the operating range and suppress noise and interference.
IR (infrared) Port
The IR port is available on the side of the transmitter for quick setup using a receiver with this function avail­able. IR Sync will transfer the settings for frequency from the receiver to the transmitter.
Battery Compartment
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 (lithium recommended).
Note: Standard zinc-carbon batteries marked “heavy-duty” or “long-lasting” are not adequate.
Batteries operate in series, with a connecting plate built into the battery door
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.
TO REMOVE

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.
When a card is installed, or when the DPR is powered on with a card already installed, the card is scanned to see if it has been formatted for use with the DPR. If it hasn’t, a prompt appears offering to do so. Follow the on-screen prompts to format the card. If the scan finds an interrupted recording, the Recovery screen will appear. The formatting operation may also be per­formed on a card which is already formatted, to erase all recordings and start over with an empty card. To do this, select Format Card from the menu.
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) IF THE CARD IS 32 GB OR SMALLER, EXFAT IF CARD IS 64+ GB.

Formatting Card
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.
IMPORTANT
The formatting of the DPR SD card sets up contigu­ous sectors for maximum efficiency in the recording process. The file format utilizes the IXML 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, 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 use only.
In short - there should be NO manipulation of the data on the card or addition of data to the card with anything other than a DPR. 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.

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.
Input...
Gain
Gain
Rolloff Phase
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.

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.

Phantom
The transmitter input jack can provide phantom power for the attached microphone if needed, with voltages at 5, 15 or 48. Phantom power will consume a slight amount of battery power, so it can also be turned off.

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 HM 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
Key Menu
KeyType
The DPR receives an encryption key via the IR port from a key generating receiver. Begin by selecting a key type in the receiver and generating a new key (key type is labeled KEY POLICY in the DSQD receiver). 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 listened to if the receiver has the matching encryp­tion key.
The DPR has three options for encryption keys:
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.
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.
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.

This menu item is only available if Key Type is set to Shared. Press Menu/Sel to sync the Encryption key to another transmitter or receiver via the IR port.

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.

DPR
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 $20 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 must have firmware version
1.5 or later for Audio, Frequency, Sleep and Lock changes.
• 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.

21750 Barrel Adapter
Mic adapter for Earthworks M30 microphone with HM, DPR and UH400a/TM transmitters.
This polarity reversing adapter may be needed to correct for asymmetrical current draw in some P48 powered condenser microphones, including older Neumann 100 Series, Rode NTG3 and others. If your microphone does not power on correctly when used with these transmitters, insert the adapter between the transmitter and microphone.
MCA-M30 Barrel Adapter
PHTRAN3
Replacement leather pouch with clear plastic screen cover, rotating belt clip and snap closure. Included with transmitter at purchase.
MCA5X
This is an optional adapter for connecting a lavaliere microphone to the DPR or HM transmitters. TA5M to XLR3-M connectors. Passes transmitter phantom power to bias the electret lavaliere microphone. Includes zener protection to limit bias voltage to protect the microphone if transmitter phantom power is set too high.
This adapter may be needed if you are experiencing noise or distortion with measurement microphones, particularly the Earthworks M30. The adapter has a common mode choke for suppressing RF noise. If your microphone signal exhibits the problems listed above when connected to a UH400, HM or DPR transmitter, insert the adapter between the microphone and the transmitter.
Insert the adapter between the transmitter and micro­phone to alleviate the problems listed above.
MCA-TPOWER
This cable adapter is to be used with the UH200D, UH400, HM and DPR plug-on transmitters with T-powered microphones. It will protect a T-power mic against the 48V phantom power setting in the transmitter while allowing normal operation. The transmitter should be set to the 15V position for best operation and minimum battery drain.

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.
dpr vX_xx.ldr is the firmware update file, where “X_xx” 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 Hybrid® 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.
dpr_boot vX_xx.ldr is the bootloader file
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 Power Button Menu and navigating to the About item.

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.
