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 67 MHz, with tuning steps in increments of 100 kHz or 25 kHz, and is set for use in the A1: 470 to 537 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.
Digital Hybrid Wireless is a revolutionary design that combines digital audio with an analog FM radio link to provide outstanding audio quality and the exemplary RF performance of the finest analog wireless systems

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
