The ew 300 IEM G2 system
With the Sennheiser evolution wireless in-ear monitoring system ew 300 IEM G2
(suitable for both stage and broadcast use), musicians, video and sound
amateurs, reporters/broadcasters, etc. can directly monitor the received sound
signals without troublesome cables or monitor speakers being required. In
addition, the system can also be used for any application where talkback signals
are to be transmitted.
The evolution wireless in-ear monitoring system ew 300 IEM G2 is a highquality state-of-the-art RF transmission systems with a high level of
operational reliability and ease of use. Transmitter and receiver permit
wireless transmission with studio-quality sound. The excellent transmission
reliability of the ew 300 IEM G2 system is based on the use of
y further optimized PLL synthesizer and microprocessor technology,
y the HDX noise reduction system,
y the pilot tone squelch control (during stereo operation),
y and the scan function for scanning the channel banks for free channels.
The channel bank system
The ew 300 IEM G2 system is available in five UHF frequency ranges with
1440 transmission/receiving frequencies per frequency range. Please note:
Frequency usage is different for each country. Your Sennheiser agent will
have all the necessary details on the available legal frequencies for your area.
Range A: 518 to 554 MHz
Range B: 626 to 662 MHz
Range C: 740 to 776 MHz
Range D: 786 to 822 MHz
Range E: 830 to 866 MHz
Transmitter and receiver have nine channel banks with up to 12 switchable
channels each.

The channel banks “1” to “8” have switchable channels that are factorypreset to a transmission/receiving frequency (see enclosed frequency table).
These transmission/receiving frequencies cannot be changed but have been
preset so that e.g. country-specific regulations on frequency usage are taken
into account. The channel bank “U” (user bank) has up to 12 switchable
channels to store your selection out of 1440 transmission/receiving
frequencies that are freely selectable within the preset frequency range.
An advantage of the factory-preset frequencies is that
y the system is ready for immediate use after switch-on,
y several in-ear monitoring systems can be operated simultaneously on the
preset channels without causing intermodulation interference.
Safety instructions
Never open electronic units! If units are opened by customers in breach of this
instruction, the warranty becomes null and void.
Keep the units away from central heating radiators and electric heaters.
Never expose them to direct sunlight.
Use the units in dry rooms only.
Use a damp cloth for cleaning the units. Do not use any cleansing agents or
solvents.
Attention! High Volume!
This is a professional transmission system. Commercial use is subject to the
rules and regulations of the trade association responsible. Sennheiser, as the
manufacturer, is therefore obliged to expressly point out possible health risks
arising from use.
This system 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 damage. The following are sure signs that you have been
subjected to excessive noise for too long a time:
y You can hear ringing or whistling sounds in your ears.
y You have the impression (even for a short time only) that you can no longer
hear high notes.
System components
The system consists of:
y 1 EK 300 IEM G2 stereo receiver
y 1 SR 300 IEM G2 stereo transmitter
y 2 batteries
y 1 telescopic antenna for SR 300 IEM G2

Indications and displays on the transmitter
Modulation display
The level display for audio signal “AF” shows the modulation of the
transmitter.
When the transmitter’s audio input level is excessively high, the level display
for audio signal “AF” shows full deflection.
When the transmitter is overmodulated frequently or for an extended period
of time, the text “PEAK” (backlit in red) flashes in alternation with the
standard display.
Button backlighting
During standby operation, the ON button is backlit in red. When the
transmitter is switched on, the SET button and the / button are
additionally backlit in green.

Attention! High volume!
Even short exposure to high volume levels will damage your hearing!
Set the volume for the connected headphones to the minimum before
putting the headphones on.
First, set the volume control ! to the lowest volume by turning it to the
left as far as possible. Then gradually turn up the volume.
Volume up? – NO!
When people use headphones, they tend to choose a higher volume than
with loudspeakers. Listening at high volume levels for long periods can
lead to permanent hearing defects. Please protect your hearing,
Sennheiser headphones have an excellent sound quality even at low
volumes.
