Wireless Monitoring Systems - Sennheiser EK 100 G3 Comprehensive Manual

Wireless Monitoring Systems

Wireless monitor systems are quietly revolutionizing live sound. In-ear monitor receivers allow
musicians to hear themselves and other instruments while performing, without the need for loud
monitor wedges. Monitor systems not only reduce stage volume and the risk of feedback, they also
provide freedom of movement and excellent hearing protection due to reduced listening levels.
Similar to the wireless microphone systems discussed earlier, wireless monitoring systems utilize very
similar building blocks:
(Rack-mount) Transmitter:
The SR 300IEM G3 transmitter can send either a mono or stereo-multiplexed signal via a pair
of balanced ¼" / XLR combination jacks. With 1,680 available UHF frequencies and easy multi-
channel operation, the system can provide wireless monitoring for every performer on stage.
Robust output power (30 mW) provides extended range and signal stability.
(portable) Receiver:
The compact EK 300IEM G3 bodypack receiver provides the performer
with clear, interference-resistant monitoring. A unique "Stereo / Focus"
mode toggles between standard stereo monitoring and Focus (mono)
mode. In Focus mode, users can freely adjust the balance of the system's
two channels to create a custom monitor mix (for example, to create a
balance between vocals with instrumentation). A large, easy-to-use knob
allows users to control volume, while an adjustable Audio Limiter can be
engaged to protect against hearing loss. Multiple receivers can receive
and listen to the same signal, allowing performers to share a monitor mix.
The ew 300IEM G3 monitor system includes Sennheiser's high quality IE4 stereo earphones, which
provide lightweight, comfortable listening. The receiver can also be used with custom ear molds
(ordered separately) for the ultimate in wireless comfort, fit and performance. The EK 300IEM G3
receiver utilizes Adaptive Diversity, which uses the IE4's output cable as a secondary antenna,
increasing system stability.
antennas / antenna Combiners:
Monitor systems use a single transmit antenna to send
their signal to the receiver. The A2003-UHF passive
directional antenna is an excellent choice for a remote
IEM transmit antenna, particularly in situations where
the performers are in a set location, such as a stage.
For larger systems, Sennheiser offers the AC3 antenna combiner, which can combine up to
four transmission signals onto a single transmit antenna, greatly reducing the possibility of
intermodulation.
