Description
The HMa from Lectrosonics is a UHF plug-on transmitter that accepts mic or line-level signals via a standard XLR connector. It has selectable 5, 15, & 48V phantom power and can be used when paired with a Lectrosonics receiver and handheld microphone – sold separately – in applications for ENG (Electronic News Gathering), EFP (Electronic Field Productions), interviews for broadcast TV, and more.
The input amplifier of the HMa transmitter uses an ultra-low noise op-amp for quiet operation and is gain controlled with a wide range dual 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.
