HMa, HMa-941, HMa/EO1, HMa/E01-B2, HMa/E02, HMa/E06, HMA/E07-941, HMa/X General Technical Description The HMa transmitter uses a DSP controlled input limiter featuring a wide range dual envelope design which cleanly limits input signal peaks over 30 dB above full modulation. Switching power supplies to provide constant voltages to the transmitter circuits from the beginning (3 Volts) to the end (1.7 Volts) of battery life, and an ultra low noise input amplifier for quiet operation.
Wideband Digital Hybrid® Plug-On Transmitter Compatibility Modes The transmitter was designed to operate with Lectrosonics Digital Hybrid Wireless® receivers and will yield the best performance when doing so. However, due to the flexibility of digital signal processing, the transmitters can also operate in various compatibility modes (vary per specific model) for use with Lectrosonics Mode 3 and IFB receivers. It will also work with certain non-Lectrosonics receivers.

These two bicolor LEDs can glow either red or green to indicate modulation levels. Full modulation (0 dB) occurs when the -20 LED first turns red.
Wideband Digital Hybrid® Plug-On Transmitter Battery Installation The transmitter is powered by two AA batteries. Note: Standard zinc-carbon batteries marked “heavy-duty” or “long-lasting” are not adequate. Attaching/Removing a Microphone The spring loaded coupler under the XLR jack maintains a secure fit to the microphone jack with continuous pressure applied by an internal spring.

When fresh batteries are installed, the unit will reboot and return to the previous settings without the need to press any buttons. This only works when the unit is fully on and transmitting. It does not work in the Standby Mode.
Wideband Digital Hybrid® Plug-On Transmitter RF Power Output (Up Button Menu) Pr (RF Power output) may be selected as: HMa: HMa/E01: HMa/E02: HMa/E06: HMa-941: Selectable 100 or 25 mW Selectable 25 or 50 mW 10 mW Selectable 50 or 100 mW EIRP Selectable 50 or 100 mW If a remote control signal is detected but the function is turned off, the message rc oFF will be displayed briefly on the transmitter’s LCD to confirm that a valid signal was received, but that the remote control function is not enabled.
HMa, HMa-941, HMa/EO1, HMa/E01-B2, HMa/E02, HMa/E06, HMA/E07-941, HMa/X AUDIO Button Settings Press the AUDIO button repeatedly to select the setting. Each time the button is released, the screen will switch to the next setting. Press and hold the button when the desired setting appears on the screen, then use the UP and DOWN arrow buttons to adjust the setting. Adjusting the Input Gain The control panel Modulation LEDs indicate the modulation level and limiter activity.
Wideband Digital Hybrid® Plug-On Transmitter • 48 Volts for microphones that do in fact require a supply greater than 18 Volts. (See following for a discussion of why 42 and not a “true” 48 Volts.) For longest battery life use the minimum phantom voltage necessary for the microphone. Many stage microphones regulate the 48 Volts down to 10 Volts internally anyway, so you might as well use the 15 Volt setting and save some battery power.
HMa, HMa-941, HMa/EO1, HMa/E01-B2, HMa/E02, HMa/E06, HMA/E07-941, HMa/X Lock/Unlock Screen Simultaneously pressing and holding both the UP and DOWN arrow buttons during normal operation starts the LOCK timer. The timer starts at three and counts down to zero. When the timer reaches zero, the keypad controls are locked. Remote Control with “Dweedle Tones” Various settings on the transmitter can be adjusted with special audio tones (“dweedle tones”) delivered to the microphone.
Wideband Digital Hybrid® Plug-On Transmitter LectroRM Android By New Endian LLC LectroRM is a mobile application for iOS and Android operating systems. Its purpose is to remotely control Lectrosonics Transmitters, including: • SM Series • WM • L Series • HMa, HMa/E01 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.
