WM, WM/E01, WM/E02, WM/X General Technical Description Servo Bias Input The voltage and current requirements of the wide variety of electret microphones used in professional applications has caused confusion and compromises in the wiring needed for wireless transmitters. To address this problem, the unique Servo Bias input circuit provides an automatically regulated voltage over a very wide range of current for compatibility with all microphones.
Watertight Transmitter Signal Encoding and Pilot Tone In addition to controlling the limiter, the DSP also encodes the digitized audio from the A/D converter and adds an ultrasonic pilot tone to control the squelch in the receiver. A pilot tone squelch system provides a reliable method of keeping a receiver output muted (audio mute) even in the presence of significant interference.
WM, WM/E01, WM/E02, WM/X Controls and Functions Modulation LEDs LCD UP Arrow Audio Input Jack Battery Compartment Caps DOWN Arrow PWR LED AUDIO Button FREQ Button LCD Screen The display is a highly visible, backlit LCD with screens for making all setup and level adjustments. The transmitter can be powered up with or without the RF output turned on. With the RF output turned off, all adjustments can be made without creating interference for other wireless systems in the vicinity.
Watertight Transmitter About Batteries Battery Compartments The transmitter is powered by two AA batteries. Lithium batteries are recommended for longest life, which typically provides over 7.5 hours of operation at room temperature with the output set to 250 mW. At 50 mW, the runtime is typically over 14 hours with lithium batteries. The battery compartments are a rugged, straightforward design with a recessed entry that captures the O-ring on the cap.
WM, WM/E01, WM/E02, WM/X Operating Instructions Power Up and Boot Sequence Lock/Unlock the Keypad Simultaneously press and hold the AUDIO and FREQ buttons until the startup count is completed. The screen will display a count from 1 to 3 as the unit boots up, then it switches to the Audio screen. As the unit turns on, the Modulation LEDs and PWR LED all glow red, then green, and then revert to normal operation.
Watertight Transmitter Menus and Settings Input Type There are four locations for setup options and settings accessed with the control panel: • UP Arrow Menu and Settings • DOWN Arrow Menu and Settings • AUDIO button settings • FREQ button settings UP Arrow Settings With the unit turned off, hold the UP arrow button and simultaneously press the AUDIO and FREQ buttons. Each successive press of the AUDIO button will step through the setup screens.
WM, WM/E01, WM/E02, WM/X Frequency Step Size Remote Control This menu item allows frequencies to be selected in either 25 kHz or 100 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 Lectrosonics Digital Hybrid receivers provide a scanning function to quickly find prospective frequencies with little or no RF interference.
Watertight Transmitter Audio Mute Beginning with firmware v2.6 on the US version, the AUDIO button can be configured to work as a mute button by turning this setting on. A quick press of the AUDIO button will then mute the audio and a message will appear on the LCD confirming that the audio is muted. Another quick press turns the audio back on.
WM, WM/E01, WM/E02, WM/X FREQ Button Settings The frequency can be displayed either in MHz or as a two-digit hexadecimal number and it can be set when the unit is in “standby” or when the transmitter is powered up in the normal operating mode. MHz Hex Code It is desirable to to set the gain so that some limiting occurs on louder peaks. The limiter is very transparent and its effect is not audible until the system is close to overload. In other words, don’t be shy about turning up the gain.
Watertight Transmitter LectroRM Android By New Endian LLC LectroRM is a mobile application for iOS and Android operating systems. Its purpose is to remotely control a variety of Lectrosonics transmitters. The app remotely changes settings on the transmitter through the use of encoded audio tones, which when received by the attached microphone, will alter the configured setting. The app was released by New Endian, LLC in September 2011.
WM, WM/E01, WM/E02, WM/X Troubleshooting Before going through the following chart, be sure that you have a good battery in the transmitter. It is important that you follow these steps in the sequence listed. SYMPTOM POSSIBLE CAUSE TRANSMITTER PWR LED OFF 1) Battery is inserted backwards or dead. 2) Transmitter not powered up. (See Operating Instructions, Power UP and Boot Sequence.
Watertight Transmitter SYMPTOM POSSIBLE CAUSE HISS AND NOISE -- AUDIBLE DROPOUTS 1) Transmitter gain (audio level) far too low. 2) Receiver antenna missing or obstructed. 3) Transmitter antenna broken or missing. 4) Operating range too great. 5) Signal interference. Turn off transmitter. If receiver’s signal strength indicator does not drop to nearly zero, this indicates an interfering signal may be the problem. Try a different operating frequency.
WM, WM/E01, WM/E02, WM/X Accessories and Replacement Parts WPMC-10 Watertight connector kit,10 piece, to terminate lavaliere microphones for use with the WM transmitter. Spring Loaded Belt Clip Model WMBCSL spring loaded belt clip. Includes hardware kit shown below. Replacement O-rings Model ORINGKIT/WM Includes replacement O-rings for battery caps and microphone plug with WM style connector, and petroleum jelly pouch. Wire Belt Clip Model WMBCWIRE includes hardware kit shown below.
Watertight Transmitter Straight Whip Antennas This is a full size cutting template used to cut the length of the whip for a particular frequency. Lay the uncut antenna on top of this drawing and trim the whip length to the desired frequency. The supplied caps can be used several different ways: 1) A color cap on the end of the whip 2) A color sleeve next to the connector with a black cap on the end of the whip (trim the closed end of the colored cap off with scissors to make a sleeve).
WM, WM/E01, WM/E02, WM/X Preventing Corrosion Whenever the transmitter has been exposed to moisture or perspiration, follow the instructions below to minimize the risk of corrosion. DRY THE UNIT BEFORE REMOVING THE MICROPHONE CONNECTOR OR BATTERY CAPS. Battery Door Update Early WM transimitters were supplied with standard battery door caps. The newer battery caps include a drying agent in a cavity to help absorb moisture inside the transmitter.
Watertight Transmitter Re-conditioning (drying out) the caps and desiccant beads An easy way to heat the doors is to use a coffee mug warmer, which typically costs about $10. The surface temperature of about 220 degrees (F) will dry the doors and desiccant, but it will not disturb any light lubricant (like the Vaseline petroleum provided with the WM) that is on the O-ring seals. It is also possible to use the mug warmer to dry out the doors without removing them from the case as shown below.
