Digital Hybrid Wireless Belt-Pack Transmitters Introduction The design of the SMWB transmitter delivers the advanced technology and features of Digital Hybrid Wireless® in a Lectrosonics belt-pack transmitter at a modest cost. Digital Hybrid Wireless® combines a 24-bit digital audio chain with an analog FM radio link to eliminate a compandor and its artifacts, yet preserve the extended operating range and noise rejection of the finest analog wireless systems.
SMWB Series Features Modulation Indicators REC Battery Status LED -40 -20 0 microSDHC memory card port Antenna Port Audio Input Jack microSDHC memory card port Antenna Port Audio Input Jack Battery Status LED Indicator AA batteries can be used to power the transmitter. The LED labeled BATT on the keypad glows green when the batteries are good. The color changes to red when the battery voltage drops down and stays red through most of the battery life.
Digital Hybrid Wireless Belt-Pack Transmitters 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.
SMWB Series Turning Power ON and OFF Turning the Power ON The power button turns the unit on and off, and provides access to a secondary menu. When the button is pressed, several different startup screens may appear depending upon the selected operating mode.

SMWB Series Setup Screen Details on Xmit Menus 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 between 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. Locking/Unlocking Changes to Settings Frequency set to fractional 25 kHz step, but step size changed to 100 kHz.
Digital Hybrid Wireless Belt-Pack Transmitters Adjusting the Input Gain Selecting Frequency 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.
SMWB Series Selecting Frequency Using Two Buttons Hold the MENU/SEL button in, then use the arrow buttons for alternate increments. 100 kHz Mode Freq. b 19 10 MHz steps and 1 block steps 1.6 MHz steps to nearest 100 kHz channel 51 494.500 100 kHz steps to next 100 kHz channel 10 MHz steps 1 block steps 1.6 MHz steps 51 41 494.
Digital Hybrid Wireless Belt-Pack Transmitters Normally, the receiver is used to find a clear operating frequency. All Lectrosonics Digital Hybrid Wireless® receivers provide a scanning function to quickly and easily find prospective frequencies with little or no RF interference. In other cases, a frequency may be specified by officials at a large event such as the Olympics or a major league ball game. Once the frequency is determined, set the transmitter to match the associated receiver.
SMWB Series 5-Pin Input Jack Wiring Audio input jack wiring: The wiring diagrams included in this section represent the basic wiring necessary for the most common types of microphones and other audio inputs. Some microphones may require extra jumpers or a slight variation on the diagrams shown. PIN 1 Shield (ground) for positive biased electret lavaliere microphones. Shield (ground) for dynamic microphones and line level inputs.

The shield contact reduces noise with some microphones and the insulation clamp increases ruggedness.
SMWB Series Input Jack Wiring for Different Sources In addition to the microphone and line level wiring illustrated below, Lectrosonics makes a number of cables and adapters for other situations such as connecting musical instruments (guitars, bass guitars, etc.) to the transmitter.

A lot of information regarding microphone wiring is also available in the FAQ section of the web site at: www.lectrosonics.
Digital Hybrid Wireless Belt-Pack Transmitters Microphone RF Bypassing Line Level Signals When used on a wireless transmitter, the microphone element is in the proximity of the RF coming from the transmitter. The nature of electret microphones makes them sensitive to RF, which can cause problems with microphone/transmitter compatibility.
SMWB Series 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. • smwb 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.
Digital Hybrid Wireless Belt-Pack Transmitters 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 SMWB.
