Digital Hybrid Wireless® US Patent 7,225,135

SMWB Series

The SMWB transmitter delivers the advanced technology and features of Digital Hybrid Wireless® combines a 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 a 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.

Controls and Functions

Battery Installation

The transmitters are powered by an AA battery(ies). We recommend using lithium for the 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  attery  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.

Setup Screen Details
Locking/Unlocking Changes to Settings
Changes to the settings can be locked in the Power Button Menu.

When changes are locked, several controls and actions can still be used:

• Settings can still be unlocked
• Menus can still be browsed
• When locked, POWER CAN ONLY BE TURNED OFF by removing the batteries.

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 smaller and may include a fraction.

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.

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 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.

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 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 the previous section Turning Power ON and OFF).
2. Navigate to the Gain setup screen.
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.
4. Use the 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 transmitter gain adjustment set according to these instructions, and do not change it to adjust the audio output level of the receiver.

Selecting Frequency
The setup screen for frequency selection offers several ways to browse the available frequencies.

Each field will step through the available frequencies in a different increment. The increments are also different in the 25 kHz mode from the 100 kHz mode.

A fraction will appear next to the hex code in the setup screen and in the main window when the frequency ends in .025, .050 or .075 MHz.

Selecting Frequency Using Two Buttons
Hold the MENU/SEL button in, then use the arrow buttons for alternate increments.
NOTE: You must be in the FREQ menu to access this feature. It is not available from the main/home screen.

If the Step Size is 25 kHz with the frequency set between even 100 kHz steps and the Step Size is then changed to 100 kHz, the mismatch will cause the hex code to display as two asterisks.

About Overlapping Frequency Bands
When two frequency bands overlap, it is possible to select the same frequency 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
LF 50
LF 70
LF 100
LF 120
LF 150| 35 Hz
50 Hz
70 Hz
100 Hz
120 Hz
150 Hz
---|---

The roll-off is often adjusted by ear while monitoring the audio.

Selecting Step Size
This menu item allows frequencies to be selected in either 100 kHz or 25 kHz increments.

If the desired frequency ends in .025, .050, or .075 MHz, the 25 kHz step size must be selected. Normally, the receiver is used to find a clear operating frequency. All  Spectrasonics digital Hybrid Wireless® receivers provide a scanning function to quickly- ly 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.
Selecting Audio Polarity (Phase)
Audio polarity can be inverted at the transmitter so the audio can be mixed with other microphones without comb filtering. The polarity can also be inverted at the receiver outputs.

Setting Transmitter Output Power
The output power can be set to:
WB/SMDWB, /X
25, 50, or 100 mW
/E01
10, 25, or 50 mW

Compatibility with microSDHC memory cards

Please note that the PDR and SPDR are designed for use with the microSDHC 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 structure 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 indicated 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 micro SDHC Logo.
If you are switching to a new rand or source of the card, we always suggest testing first before using the card on an acritical 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.

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 recording. 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-formatted with the SMWB/SMDWB to prepare it again for recording. The WB/ 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 efficiency 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 addition of data to the card with anything other than an SMWB/SMDWB recorder. 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.
