Introduction
The WM transmitter is designed to resist damage when
used in wet or dusty conditions and also oer a com-
prehensive feature set that makes it equally at home in
lm and television production and on stage.
A solid machined aluminum housing with a corrosion re-
sistant nish hosts dual battery compartments, a mois-
ture 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 without excessive
deformation of the O-rings.
The antenna is made of an extremely durable, multi-
strand alloy that will withstand heavy abuse. It is mount-
ed with a compression sealed strain relief that prevents
dust and moisture from entering the housing.
As the rst stage in the signal processing chain, the
input preamp section includes very high quality, low
noise components with a wide range of gain adjustment
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 ac-
cessed screens on the LCD simplify setup and adjust-
ments.
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 eciency
as analog systems, the same long battery life as analog
systems, plus the excellent audio delity 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.
