SMWB Series
The SMWB transmitter delivers the advanced technology and features of Digital
Hybrid Wireless®and combines 24-bit digital audio chain with an analog FM
radio link to eliminate a compandor and its artifacts, yet preserves the extended
operating range and noise rejection of the finest analog wireless systems. DSP
“compatibility modes” allow the transmitter to also be used with a variety of
analog receivers by emulating the compandors found in earlier Lectrosonics
analog wireless and IFB receivers, and certain receivers from other manufactur-
ers (contact the factory for details).
Plus, the SMWB 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. 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
updates capability without the need for a USB cable.

Battery Installation
The transmitters are powered by AA battery(ies). We recommend using
lithium for longest life.
Because some batteries run down quite abruptly, using the Power LED to
verify battery status will not be reliable. However, it is possible to track battery
status using the battery timer function available in Lectrosonics Digital Hybrid
Wireless receivers.
The battery door opens by simply unscrewing the knurled knob part way
until the door will rotate. The door is also easily removed by unscrewing the
knob completely, which is helpful when cleaning the battery contacts. The
battery contacts can be cleaned with alcohol and a cotton swab, or a clean
pencil eraser. Be sure not to leave any remnants of the cotton swab or eraser
crumbs inside the compartment.
A small pinpoint dab of silver conductive grease* on the thumbscrew threads
can improve battery performance and operation. Do this if you experience a
drop in battery life or an increase in operating temperature.
Insert the batteries according to the markings on the back of the housing. If
the batteries are inserted incorrectly, the door may close but the unit will not
operate.
*if you are unable to locate a supplier of this type of grease - a local electron-
ics shop for example - contact the factory for a small maintenance vial.

Connecting the Signal Source
Microphones, line level audio sources and instruments can be used with
the transmitter. Refer to the manual section entitled Input Jack Wiring for
Different Sources for details on the correct wiring for line level sources and
microphones to take full advantage of the Servo Bias circuitry.
Turning Control Panel LEDs ON/OFF
From the main menu screen, a quick press of the UP arrow button turns the
control panel LEDs on. A quick press of the DOWN arrow button turns them
off. The buttons will be disabled if the LOCKED option is selected in the Power
Button menu.
The control panel LEDs can also be turned on and off with the LED Off option
in the Power Button menu.
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, step size and compatibility modes 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 indica-
tion 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 Off Off
-20 dB to -10 dB Green Off
-10 dB to +0 dB Green Green
+0 dB to +10 dB Red Green
Greater than +10 dB Red Red
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.
Gain
Freq
Rolloff
Compat -40 -20 0

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.

LECTROSONICS, INC.12
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 trans-
mitter gain adjustment set according to these instructions, and do not
change it to adjust the audio output level of the receiver.

About Overlapping Frequency Bands
When two frequency bands overlap, it is possible to select the same frequen-
cy at the upper end of one and the lower end of the other. While the frequency
will be the same, the pilot tones will be different, as indicated by the hex
codes that appear.
In the following examples, the frequency is set to 494.500 MHz, but one is
in band 470 and the other in band 19. This is done intentionally to maintain
compatibility with receivers that tune across a single band. The band number
and hex code must match the receiver to enable the correct pilot tone.

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:
• LF 35 35 Hz
• LF 50 50 Hz
• LF 70 70 Hz
• LF 100 100 Hz
• LF 120 120 Hz
• LF 150 150 Hz
The roll-off is often adjusted by ear while monitoring the audio.

Compatibility with microSDHC
memory cards
Please note that the PDR and SPDR are designed for use with the microS-
DHC 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 struc-
ture and are NOT compatible with the SPDR recorder. These are typically
used with later generation video systems and cameras for image applications
(video and high resolution, high speed photography).
ONLY the microSDHC memory cards should be used. They are available in
capacities from 4GB to 32GB. Look for the Speed Class 10 cards (as indicat-
ed 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 test-
ing 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.
UHS Speed Class I Stand-alone

Formatting SD Card
New microSDHC memory cards come pre-formatted with a FAT32 file system
which is optimized for good performance. The PDR relies on this performance
and will never disturb the underlying low level formatting of the SD card. When
the SMWB/SMDWB “formats” a card, it performs a function similar to the
Windows “Quick Format” which deletes all files and prepares the card for re-
cording. 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-for-
matted with the SMWB/SMDWB to prepare it again for recording. The SMWB/
SMDWB never low level formats a card and we strongly advise against doing
so with the computer.
To format the card with the SMWB/SMDWB, 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 SMWB/
SMDWB 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 ef-
ficiency 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 SMWB/SMDWB 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 SMWB/SMDWB 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 addi-
tion of data to the card with anything other than an SMWB/SMDWB record-
er. 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.
