The HMa plug-on transmitter has been introduced, the latest addition to the Digital Hybrid Wireless range. Lectrosonics claims the HMa will ideally match any microphone or line level source, with its input gain range of 44dB and tuning range of 76MHz in 100kHz or 25kHz steps, up to 3,072 frequencies per band.
A USB port makes firmware updates possible in the field. The HMa is aimed at a variety of wireless microphone applications including wireless boom, plant miking and ENG in particular.
The HMa combines 24-bit digital audio with analogue FM transmission resulting in superior radio reliability with superb audio performance. Audio frequency response of the HMa is 40Hz – 20kHz ±1dB. Phantom power is selectable at 5V, 15V and 48V, or
can be turned off for use with dynamic microphones and line level signal sources.
The patented Digital Hybrid Wireless process delivers compandor-free audio and uses an analogue FM carrier to transmit a specially encoded signal, which delivers digital audio quality while spectrum efficient. The signature cam lock and quick release mechanism makes it easy to securely attach any microphone then detach it in seconds.
Karl Winkler, vice president of sales/service, Lectrosonics, said: “The HMa is the latest in our long history of making professional plug-on transmitters for a wide range of microphone applications. The HMa will be a perfect match for any of our receivers, including the Venue and Venue 2, the SR series, the LR, and the UCR series, and new receivers yet to come.”
