This product is capable of producing sound pressure exceeding
85 dB(A). 85 dB(A) is the sound pressure corresponding to the
maximum permissible volume which is by law (in some countries)
allowed to affect your hearing for the duration of a working day. It is
used as a basis according to the specifications of industrial medicine.
Higher volumes or longer durations can damage your hearing. At higher
volumes, the duration must be shortened in order to prevent hearing
damage. The following are sure signs that you have been subjected to
excessive noise for too long a time:
– You can hear ringing or whistling sounds in your ears.
– You have the impression (even for a short time only) that you can no
longer hear high notes.

The EK 300 IEM G3 diversity receiver
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
channels
• Adjustable and switchable limiter
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.
This 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 7 UHF frequency ranges with
1,680 receiving frequencies per frequency range:
