The Lectrosonics HMa Wireless Plug-On Transmitter with RE50B Handheld Mic Kit from Fotohaus Klinger is designed to let you add a handheld mic to your Lectrosonics wireless system, for professional broadcast production.

The kit comes with the HMa Digital Hybrid plug-on transmitter and the Electro-Voice RE50B handheld dynamic microphone, an industry standard for news correspondents around the globe.

The HMa from Lectrosonics is 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.
