Accessorizing A Wireless System; Component Requirements - Sennheiser EK 100 G3 Manual

The compact EK300IEMG3 bodypack
receiver provides each performer with
clear, interference-resistant monitor-
ing. Like the transmitter, it features
frequency number and channel num-
ber display and a Focus control, which
sR300IemG3 Transmitter
allows the user to adjust the balance
of the system's two channels to create
a custom monitor mix. The receiver
also features an adjustable Audio Limiter, which restricts volume to protect against
hearing loss. The evolution Wireless Monitor System comes supplied with high
quality IE4 stereo ear phones, which provide lightweight comfortable listening, but
can also be used with custom ear molds (ordered separately) for the ultimate in
wireless comfort, fit and performance.
Accessorizing a System
eK300IemG3
Sennheiser offers many useful accessories for the evolution wireless G3 series.
Bodypack Receiver
GA3 Rack Adapter
For convenient side-by-side mounting of up to two fixed EM receivers, SR
transmitters, ASA1 splitters or AC3 combiners in a standard 19" rack.
Am2 front Antenna mount
For use with the GA3 for use with fixed receivers or transmitters in a stan-
dard19" rack-mounting arrangement, the AM2 is used to mount anten-
nas in the front. This enhances performance over having the antennas
"buried" inside the rack.
AsA1 Antenna splitter/dc power distributor
Active antenna splitter that feeds RF signal and DC power through the RG58 cable to up to four fixed
receivers simultaneously. This reduces the number of antennas required and makes for a very "clean"
installation. Two ASA1 units can be coupled to feed up to eight receivers from a single pair of anten-
nas. More than eight receivers can be fed from a single pair of antennas when feeding the output of an
ASA1 into two or more ASA1 units.

Component Requirements

Generally speaking, wireless systems are sold as sets which contain one transmitter and one receiver.
If you require more than a single transmitter or receiver, there are several important points you must
consider. First, a transmitter and receiver must be able to tune to the same frequency in order to work
together. For example, a VHF transmitter cannot work with a UHF receiver. Secondly, transmitters and
receivers must both use the same compander circuitry in order to work together. Since the transmit-
ter's compander circuit dictates the way the audio is "compressed" into an RF signal, the receiver on
the other end must have compatible circuitry to "uncompress" the RF signal into a high-quality audio
signal. evolution wireless systems employ Sennheiser's proprietary HDX™ compander circuitry for
superior signal-to-noise ratios and quiet operation. evolution components can only be used with other
HDX™-enabled Sennheiser components. Because of the flexibility of HDX™, all evolution components are
compatible with one another regardless of generation (G1/G2/G3) as long as you can tune to the same
frequency. In addition, evolution components are compatible with the 2000 series. As a result, evolu-
tion wireless G3 offers a high degree of frequency agility in each range (1680 frequencies). This allows
you to easily configure everything from a basic setup to large multichannel systems, depending on the
surrounding RF environment.
