The Lectrosonics HMa Plug-On Wireless Transmitter 537-607MHzfrom Lectrosonics HMa Plug-On Wireless Transmitter 537-607MHzis a UHF plug-on transmitter that accepts mic or line-level signals via a standard XLR connector. The transmitter is designed to be paired with a Lectrosonics receiver and handheld microphone (sold separately)for use in applications for ENG (Electronic News Gathering), EFP (Electronic Field Productions), interviews for broadcast TV, and more. The HMa offer phantom power selectable at 5, 15, and 48V—allowing it to work with a wide variety of condenser mics. Of course you can switch the phantom power off entirely if you're using a dynamic microphone.

The input amplifier of the HMa transmitter uses an ultralow-noise op-amp for quiet operation and offers input gain control along with a wide-range dual-release envelope limiter. A 24-bit A to D converter digitizes the audio, and filters the supersonic noise above 21 kHz. The resulting signal is encoded with a proprietary algorithm to produce an analog data signal for RF transmission.

This version of the HMa features a tuning range of 70 MHz, with tuning steps in increments of 100 kHz or 25 kHz, and is set for use in the B1: 537 to 607 MHz range. DSP compatibility mode allows the transmitter to work with legacy analog wireless microphone and IFB receivers as well as some receivers from other manufacturers.

Finally, the transmitter is powered by two AA batteries, with status indicated by a multi-color LED. A USB port is also provided for firmware updates, and an IR (infrared) port is included to simplify setup with IR enabled receivers.

Selectable 50/100 mW output power

70 MHz tuning range in 100 kHz or 25 kHz steps

The antenna is formed between the machined aluminum housing of the transmitter and the attached microphone or cable. It functions as a dipole radiator when attached to a hand-held microphone and somewhat like a ground plane antenna when connected with a cable or plugged directly into a mixer

A: This wireless receiver can be connected to an input of the Zoom F8N digital recorder, but it does require to be paired with the L Series LT Bodypack Wireless Transmitter (A1: 470 to 537 MHz), BH #LELTA1.

Q: 2. Do non servo ta5f connectors work with the lmb transmitter?

A: Yes, the Lectrosonics L-Series LMb Bodypack Wireless Transmitter and all other Lectrosonics transmitters with 5-pin inputs have servo bias inputs that can also be used with other conventional wiring configurations.

Q: 3. Does the transmitter come with a belt clip included?

A: The Lectrosonics LMb Digital Hybrid Wireless Beltpack Transmitter does come with a metal belt clip.

Q: 4. I want to use a couple of Lectrosonics M-150 lavs as hard-wired backups to my normal gear. The stated compatible models are: Lectrosonics HM, UH400 and UH400a. M-150 uses a 5 pin female TA5 so will it also work with this adapter?

A: The MCA5X will work with all Lectrosonics mics wired with a 5 pin female (TA5) connector, however it is designed for use with their Plug On transmitters only. It will NOT work when connected to a microphone input on a mixer or a recorder.

Q: 5. What adapter do I need to connect to a Zoom H4n?

A: Hi Gabriel,I think you need to be much more specific. So you want to connect something to an H4N - but what exactly do you want to connect to it?Howard

Q: 6. Which ones can be used in the U.S.

A: All of the Lectrosonics HMa Plug-On Wireless Transmitters that we sell can be used in the United States.

Q: 7. It is possible to combine a Lectrosonics L-Series LMb (B1: 537 to 614 MHz) with a UCR 411A?

A: Yes, the LMb transmitter can be used with all Lectrosonics Digital Hybrid Wireless receivers including the UCR411a when the compatibility mode for the transmitter and receiver are both set to the "Nu Hybrid" compatibility mode. Lectrosonics notes that if your receiver does not have Nu Hybrid mode, then set the receiver to the "Euro Digital Hybrid Wireless" compatibility mode.

Q: 8. Can you use this with a SRa receiver

A: So long as your SRa receiver has the same frequency ranges as the LMb transmitter, the LMb transmitter will work with an SRa receiver.

Q: 9. Is there a battery eliminator made for this?

A: No,at this time there are no battery eliminators or alternate powering options available for the LMb transmitter.

Q: 10. Is it compatible with Sennheiser G4 transmitter?
