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.

Main Window Indicators
The Main Window displays the block number, Standby or Operating mode,
operating frequency, audio level, battery status and programmable switch
function. When the frequency step size is set at 100 kHz, the LCD will look
like the following.

LECTROSONICS, INC.10
Changing the step size never changes the frequency. It only changes the way
the user interface works. If the frequency is set to a fractional increment be-
tween even 100 kHz steps and the step size is changed to 100 kHz, the hex
code will be replaced by two asterisks on the main screen and the frequency
screen.

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.
