The SKM 300 G3 radio microphone family
The SKM 300 G3 radio
microphone family
The SKM 300 G3 radio microphone is part of the
evolution wireless series generation 3 (ew G3).
This series offers high-quality state-of-the-art RF
transmission systems with a high level of operational
reliability and ease of use. Transmitters and receivers
permit wireless transmission with studio-quality sound.
Features of the evolution wireless 300 G3 series:
•
Optimized PLL synthesizer and microprocessor
technology
•
HDX noise reduction system
•
Pilot tone squelch control
•
True diversity technology
•
Switching bandwidth of 42 MHz
•
Increased immunity to intermodulation
interferences in multi-channel operation
•
Interchangeable microphone heads, allowing the use
of different pick-up patterns and sensitivities
•
Extended muting function due to MIC button on the
radio microphone
and
The frequency bank system
The radio microphone is available in 6 UHF frequency
ranges with 1,680 transmission frequencies per
frequency range:
Range A:
516 – 558
Range G:
566 – 608
Range B:
626 – 668
Range C:
734 – 776
Range D:
780 – 822
Range E:
823 – 865
Each frequency range (A–E, G) offers 26 frequency
banks with up to 24 channels each:
Channel 1 – frequency preset
Channel 2 – frequency preset
Frequency bank 1 ... 20
Channel 24 – frequency preset
Channel 1 – freely selectable frequency
Channel 2 – freely selectable frequency
Frequency bank U1 ... U6
Channel 24 – freely selectable frequency
Each of the channels in the frequency banks “1” to “20”
has been factory-preset to a fixed transmission
frequency (frequency preset).
SKM 300 G3 | 3
The SKM 300 G3 radio microphone family
The factory-preset frequencies within one frequency
bank are intermodulation-free. These frequencies
cannot be changed.
For an overview of the frequency presets, please refer to
the supplied frequency information sheet. Updated
versions of the frequency information sheet can
be downloaded from the SKM 300 G3 product page on
our website at www.sennheiser.com.
The frequency banks “U1” to “U6” allow you to freely
select and store transmission frequencies. It might be
that these transmission frequencies are not
intermodulation-free.
Areas of application
The radio microphone family can be combined with the
EM 300 G3 rack-mount receiver.
The EM 300 G3 rack-mount receiver is available in the
same UHF frequency ranges and is equipped with the
same frequency bank system with factory-preset
frequencies. This has the advantage 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.

A special feature of the Sennheiser evolution wireless
ew 300 G3 series is the consistent, intuitive menu
structure of transmitters and receivers. As a result,
adjustments to the settings can be made quickly – even
in stressful situations, for example on stage or during a
live show or presentation.
Make use of the possibility to adjust settings
via the operating menu of the receiver and
to transfer these settings to the radio
microphone.
For more information on how to transfer

Setting transmission frequencies and frequency banks
– “Tune”
When you have selected one of the system banks
and then select the “Tune” menu item, the radio
microphone automatically switches to channel 1
of the frequency bank “U1”. In this case, “U1.1”
briefly appears on the display panel.
Upon delivery, the channels of the frequency
banks “U1” to “U6” are not assigned a
transmission frequency.
When you are in the “Tune” menu item, the RF
signal is deactivated.
Via the “Tune” menu item, you can set a transmission
frequency to be stored in the current channel or you can
select a different channel in one of the frequency banks
“U1” to “U6” and assign this channel a transmission
frequency.
It is vital to observe the notes on frequency
selection on page 29.

The radio microphone adds an inaudible signal, known
as the pilot tone, to the transmitted signal. The receiver
detects and evaluates the pilot tone.
The pilot tone supports the receiver’s squelch function,
thus protecting against interference due to RF signals
from other devices.
Devices of the ew 300 G1 series (generation 1) do not
support the pilot tone function. Therefore, please
observe the following when combining a radio
microphone or receiver of the ew 300 G3 series
(generation 3) with devices from an earlier evolution

Synchronizing the radio microphone with a receiver
Synchronizing the radio
microphone with a receiver
When synchronizing the radio microphone with a
receiver, please observe the following:
Only use a radio microphone and a receiver from
the same frequency range (see the type plate
on the radio microphone and the receiver).
Make sure that the desired frequencies are
listed in the enclosed frequency information
sheet.
Make sure that the desired frequencies are
approved and legal in your country and, if
necessary, apply for an operating license.
Synchronizing the radio microphone with
the receiver – individual operation
Upon delivery, the radio microphone and the receiver
are synchronized with each other.
However, if you cannot establish a transmission link
between radio microphone and receiver, you have to
synchronize the channels of the devices.
For information on automatic synchronization of
the radio microphone with the receiver (individual
operation), refer to the instruction manual of the
receiver. The relevant information is marked with the
icon.
Alternatively, you can set the channel on the radio
microphone manually:
Make sure that you set the radio microphone to the
same frequency bank and the same channel as the
receiver (see page 23).
If you still cannot establish a transmission link, refer to
the chapter “If a problem occurs ...” on page 32.
Synchronizing radio microphones with
receivers – multi-channel operation
Combined with ew 300 G3 receivers, ew 300 G3 radio
microphones can form transmission links that can be
used in multi-channel systems.
For information on automatic synchronization of radio
microphones with receivers (multi-channel operation),
refer to the instruction manual of your receiver.
For more information on multi-channel operation, visit
the SKM 300 G3 product page at www.sennheiser.com.

Cleaning and maintaining the radio microphone
Cleaning and maintaining the
radio microphone
CAUTION
Liquids can damage the electronics of the radio
microphone!
Liquids entering the housing of the product can cause a
short-circuit and damage the electronics.
Keep all liquids away from the radio microphone.
Use a cloth to clean the radio microphone from time
to time.
Do not use any solvents or cleansing agents.
To clean the sound inlet basket of the microphone head
(MMD 835-1, MMD 845-1, MME 865-1):
Unscrew the upper sound inlet basket from the
microphone head by turning it counterclockwise (see
diagram).
CAUTION
Liquids will damage the microphone head!
Liquids will damage the microphone head.
Only clean the upper sound inlet basket.
Remove the foam insert.
To clean the sound inlet basket:
– Use a cloth to clean the upper sound inlet basket
from the inside and outside
– or scrub with a brush and rinse with clear water.
If necessary, clean the foam insert with a mild
detergent or replace the foam insert.
Dry the upper sound inlet basket.
Dry the foam insert.
Reinsert the foam insert.
Replace the sound inlet basket on the microphone
head and screw it tight.
You should also clean the contact rings of the
microphone head from time to time:
Wipe the contact rings of the microphone head with
a cloth.
30 | SKM 300 G3
Recommendations and tips
Recommendations and tips
... for optimum sound
•
Hold the radio microphone in the middle of the
microphone body. Holding it close to the sound
inlet basket will influence the radio microphone’s
pick-up pattern.
•
You can vary the bass reproduction by increasing/
decreasing the talking distance.
•
For best results, make sure that the sensitivity is
correctly adjusted.
... for optimum reception
•
Transmission range depends to a large extent on
location and can vary from about 10 m to about
150 m. There should be a “free line of sight”
between transmitting and receiving antennas.
•
To avoid overloading the receiver, observe a
minimum distance of 5 m between transmitting
and receiving antennas.
•
Only hold the radio microphone by its body. If you
touch the antenna of the radio microphone, the
transmission power will be considerably reduced.
... for multi-channel operation
•
For multi-channel operation, you should only use
the channels within one frequency bank. Each of
the frequency banks “1” to “20” accommodates
factory-preset frequencies which are intermodulation-free.
•
When using several radio microphones/
transmitters simultaneously, interference can be
avoided by maintaining a minimum distance
of 20cm between two radio microphones/
transmitters.
