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 manufactur­ers (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
update capabilities without the need for a USB cable or driver issues.

Battery Installation

The transmitter is powered by two
AA batteries. 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
electronics shop for example - con­tact the factory for a small mainte­nance vial.
