Lectrosonics HMa Digital Hybrid Wireless UHF Plug-On Transmitter, B1 537.600 - 607.950 MHz
This unique plug-on transmitter design will ideally match any microphone or line level source via a standard XLR connector. Phantom power is selectable at 5, 15 and 48 volts, or can be turned off for use with dynamic microphones and line level signal sources.
The design includes a wide tuning range of up to 76 MHz, with tuning steps in increments of 100 kHz or 25 kHz, (19 MHz for block 941 version, for 695 frequencies).
Along with providing peerless audio quality with wide frequency response and dynamic range in Nu Hybrid mode, the technology used in the HMa includes compatibility modes for Lectrosonics Mode 3 and IFB receivers.
Key Features
- Accepts audio from any microphone or audio source with an XLR connector
- Selectable 5, 15, 48 volt phantom power
