The Transmitter
The transmitter has a fairly straightforward job: to take the source input signal from a microphone or
line-level input (a guitar, for example), convert it into an RF signal, and transmit it. It sounds easy, but
there are a number of variables involved in producing accurate and dependable transmissions.

there are a number of variables involved in producing accurate and dependable transmissions.
While many other wireless systems use transmitters that may have enough power to work well on a
small stage, they lack the operating range and performance for a professional event. With this in mind,
Sennheiser transmitters are intentionally engineered to provide more than enough output power for
virtually any application. Sennheiser equips the evolution wireless G3 series of transmitters with 30
mW of output power for at least 300 feet of range (line of sight). As a result, the user gets increased
range and strong, stable transmission regardless of the conditions. Additionally, all of our transmitters
feature metal housings, making them capable of enduring life on the road.

Most importantly, a transmitter must be able to convert the audio signal into an RF signal without los-
ing sound quality or accuracy. Any time a signal is converted from one type (analog audio) to another
(RF, for example) there is a danger of losing some aspect of the original sound or adding unwanted
noise in the transition. To guard against this, Sennheiser employs a proprietary noise-reduction system
called HDX™. HDX™ circuitry allows the transmitter to produce an RF signal that maximizes the micro-
phone’s signal-to noise ratio while avoiding the RF noise inherent in most systems. Once the transmit-
ted RF signal reaches the receiver, it is re-converted into analog audio (using reciprocal receiver-side
HDX™ technology) with stunning accuracy and quality. This results in audio that sounds as good as
that of a wired microphone. As a result, Sennheiser G3 systems have an amazing frequency response of
25 Hz to 18 KHz (line).

Types of Transmitters
There are four basic types of wireless transmitters:
1) Bodypack transmitter
A bodypack transmitter is a versatile transmitter
platform that can be used with a wide variety of input
options. Sennheiser evolution bodypack transmitters
(SK100G3, SK300G3, and SK500G3) all offer adjustable
input sensitivity controls and can be used with both mic-
level sources, such as lavalier or headset microphones,
and also high-impedance line sources, such as electric or
acoustic guitars. Because of their compact and rugged
design, bodypack transmitters are widely used with
lavalier microphones (ME2 Omni, ME4 Cardioid), and
headsets (ME3-ew). Applications range from musical
and theatrical stages everywhere to use on film and
television sets.
