Introduction
The WM transmitter is designed to resist damage
when used in wet or dusty conditions and also offer
a comprehensive feature set that makes it equally at
home in film and television production and on stage.
A solid machined aluminum housing with a corrosion
resistant finish hosts dual battery compartments, a
moisture sealed control panel with backlit LCD and
enlarged membrane switches. Recessed seats for the
O-rings in the battery caps and input jack allow the
caps and mic connector to be tightened securely with-
out excessive deformation of the O-rings.
The antenna is made of an extremely durable, multi-
strand alloy that will withstand heavy abuse. It is
mounted with a compression sealed strain relief that
prevents dust and moisture from entering the housing.
As the first stage in the signal processing chain, the
input preamp section includes very high quality, low
noise components with a wide range of gain adjust-
ment in 1 dB increments and a DSP-controlled input
limiter. Dual color LEDs on the control panel accurately
indicate audio input level for precise gain adjustment.
Easily accessed screens on the LCD simplify setup
and adjustments.
Output power is adjustable to provide either extended
operating range or extended battery life as needed for
the application.
The Digital Hybrid Wireless® design (US Patent
7,225,135) combines 24-bit digital audio with analog
FM resulting in a system that has the same operating
range as analog systems, the same spectral efficiency
as analog systems, the same long battery life as ana-
log systems, plus the excellent audio fidelity typical of
pure digital systems.
The DSP-based design works with all Digital Hybrid
receivers, and is backward compatible for use with
Lectrosonics IFB receivers and some other brands of
analog wireless receivers.
