The EK 300 IEM G3 diversity receiver
This diversity receiver is part of the evolution wireless series generation 3
(ew G3). With this series, Sennheiser offers high-quality state-of-the-art
RF transmission systems with a high level of operational reliability and
ease of use. Transmitters and receivers are designed for monitoring appli-
cations and permit wireless transmission with studio-quality sound.
Features of the evolution wireless 300 IEM G3 series:
• Optimized PLL synthesizer and microprocessor technology
• HDX noise reduction system
• Adaptive diversity technology
• Switching bandwidth of 42 MHz
• Scan function (Easy Setup) for scanning the frequency banks for unused

Adaptive diversity
This diversity receiver uses the ground connection of the earphones cable
as its second antenna to provide improved reception.
Areas of application
The receiver can be combined with the SR 300 IEM G3 transmitter.
The transmitter is available in the same UHF frequency ranges and is
equipped with the same frequency bank system with factory-preset
frequencies. An advantage of the factory-preset frequencies is that
• a transmission system is ready for immediate use after switch-on,
• several transmission systems can be operated simultaneously on the
preset frequencies without causing intermodulation interference.
The frequency bank system
The diversity receiver is available in 6 UHF frequency ranges with
1,680 receiving frequencies per frequency range:
