Lectrosonics Introduces New HM Plug-On Wireless Transmitter

Lectrosonics has announced the introduction of the new HM Plug-on Transmitter, the latest in a long line of plug-on style transmitters developed by the company.

The new HM transmitter provides100 mW of RF power as well as several unique features, including an LCD with a membrane-switch control panel and audio level meter for ease of setting and operation.

It includes a user-selectable high-pass filter, enabling it to be employed for a wider range of applications from ENG (electronic news gathering) to audio system analysis when used as part of the Lectrosnics TM400 system. It is powered by two AA batteries, providing an operating time in excess of 12 hours with lithium cells.

The HM transmitter also employs Lectrosonics’ acclaimed Digital Hybrid Wireless technology for operation in its native, compandor-free hybrid mode, or in compatibility modes for Lectrosonics 200 Series, 100 Series, and IFB products along with receivers from two other manufacturers.

The body of the transmitter is meticulously machined from solid aluminum alloy to aerospace tolerances and finished in Teflon-impregnated nickel plating to ensure the extreme ruggedness and durability required in field production.

The HM also features a quick-locking XLR connector to ensure that the transmitter does not separate from the microphone while in use.

In addition, it incorporates a unique, multi-voltage phantom power feature that enables the transmitter to be used with virtually any microphone, including high-current condenser types—expanding the HM’s usefulness in high-end applications such as motion picture production.

The HM’s RF output circuit uses a one way circulator/isolator that greatly reduces the RF intermodulation produced when multiple transmitters are used in close proximity to one another.

Frequency response is rated at 40 Hz – 20 kHz ±1 dB, -3 dB at 35 Hz, while dynamic range is 125 dB (A). RF output is 100 mW.

Karl Winkler, Lectrosonics’ Director of Business Development, states, “The new HM transmitter is a logical extension to the line of Lectrosonics’ high performance wireless transmitter products. Incorporating our Digital Hybrid Wireless technology for superior audio performance, rugged build quality to ensure optimum performance under the most challenging conditions, and a rich feature set including an LCD display that dramatically enhances operational efficiency, I’m confident the new HM transmitter will receive a warm welcome by audio professionals involved in a wide range of wireless applications.”
