Manufacturer's Description
The HM Digital Hybrid Wireless® plug-on transmitter features a DSP-based design that allows the transmitter to operate in its native Digital Hybrid Wireless® mode, Lectrosonics 200 Series, 100 Series, IFB product groups, plus two modes for compatibility with analog receivers from other manufacturers. A unique multi-voltage phantom power feature allows the transmitter to be used with virtually any microphone, including high-current condenser types, expanding its usefulness in high-end applications such as motion picture production.

The transmitter provides 256 frequencies in standard frequency blocks between 470 and 692 MHz. The input amplifier uses an ultra low noise op-amp for quiet operation. It is gain controlled with a wide range dual envelope limiter, providing over 30 dB of headroom above full modulation. A 24-bit A-D converter digitizes the audio, then filters supersonic noise above 21 kHz. The resulting signal is encoded with a proprietary algorithm to produce an analog data signal for RF transmission. The underlying RF link is an optimized FM system with +/-75 kHz wide deviation for a high signal to noise ratio.

The membrane switch control panel provides quick access to all setup screens. The housing is machined from a solid billet to provide a rugged, lightweight finished assembly.

FCC Consumer Alert
Most users do not need a license to operate this wireless microphone system. Nevertheless, operating this microphone system without a license is subject to certain restrictions: The system may not cause harmful interference; it must operate at a low power level (not in excess of 50 milliwatts); and it has no protection from interference received from any other device. Purchasers should also be aware that the FCC is currently evaluating use of wireless microphone systems, and these rules are subject to change. For more information, call the FCC at 1–888–CALL–FCC (TTY: 1–888–TELL–FCC) or visit the FCC's wireless microphone Web site.

If you're a licensed Part 74 operator, you may continue to use 50mW and greater wireless systems under certain conditions. Eligible parties include a person or organization engaged in the production or filming of motion pictures or television, so, to the best of our knowledge, this includes below the line crew. More information on also can be found here. To apply for a license, visit www.fcc.gov/Forms/Form601/601.html
