Lectrosonics HMa, CARDIOID CNDNSR CPSL HEAD FOR HH TX, VARI-MIC EQ
The Lectrosonics HMa is a UHF plug-on transmitter that accepts mic or line-level signals via a standard XLR connector. The Lectrosonics HMa 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 Lectrosonics 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.
Also, the Lectrosonics HMa features a wide tuning range of 76 MHz, with tuning steps in increments of 100 kHz or 25 kHz for up to 3072 frequencies, the HMa transmitter also covers three standard 25.6 MHz Lectrosonics frequency blocks. Each block provides 256 different pilot tone frequencies. Legacy analog wireless microphone and IFB receivers are designed to work in DSP compatibility mode, 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.
The Lectrosonics HMa has 3 frequency range:
- HMa A1 : 470 to 537 MHz
- HMa B1 : 537 to 607 MHz
- HMa 941 : 941:941 to 951 MHz
