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.

When the frequency step size is set to 25 kHz, the hex number will appear

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.
