Description

Designed for wet or dusty environments, the WM transmitter features O-ring sealed battery compartments and input jack, a compression sealed antenna port and gasket sealed control panel and back cover. Dual AA batteries provide twice the operating time of earlier watertight transmitter designs. Larger membrane switches and control panel and a highly visible, backlit LCD enhance the user interface.

Features:

  • Selectable output power to maximize battery life or operating range (50, 100 or 250 mW)
  • Machined aluminum, corrosion resistant housing
  • Water resistant seals for use in wet environments
  • LCD interface with lockout option
  • Programmable compatibility modes for use with a wide variety
  • of different receivers
  • Servo Bias input circuitry with selectable voltage

Digital Hybrid Wireless® is a revolutionary new design that combines digital audio with an analog FM radio link to provide outstanding audio quality and the exemplary RF performance of the finest analog wireless systems.

This overcomes channel noise in a dramatically new way, digitally encoding the audio in the transmitter and decoding it in the receiver, yet still sending the encoded information via an analog FM wireless link. This proprietary algorithm is not a digital implementation of an analog compandor.

Instead, it is a technique which can be accomplished only in the digital domain. The process eliminates compandor artifacts, expanding the applications to include test and measurement of acoustic spaces and musical instruments.

Included Accessories:

  • 2 - Dual Lithium AA Batteries
  • 1 - Microphone (Part #M152/WP)
  • 1 - Belt Clip (Part #WMBCSL)
  • 1 - O-ring Kit (Part #ORINGKIT/WM)
  • 1 - Quickstart Guide
