The SKP 300 G3 plug-on
transmitter
The SKP 300 G3 plug-on transmitter is part of the evolution wireless series ew 300 G3. This series offers highquality 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 SKP 300 G3 plug-on transmitter:
• Optimized PLL synthesizer and microprocessor
technology
• HDX noise reduction system
• Pilot tone squelch control
• Switching bandwidth of up to 42 MHz
• Increased immunity to intermodulation and interferences in multi-channel operation
• 48 V phantom powering
Areas of application
The plug-on transmitter can be combined with the
EM 300 G3 rack-mount receiver. The EM 300 G3 rackmount 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.
Combinable
Transmitter
with ...
SKP 300 G3 dynamic and
condenser
microphones.
We recommend using
Sennheiser
microphones.
Receiver
EM 300 G3
Transmitter and receiver must have at least
software version 1.7 (see page 23).

The frequency bank system
The plug-on transmitter is available in 7 UHF frequency
ranges with up to 1,680 transmission frequencies per
frequency range:
Range GB:
566 – 608
606 – 648
626 – 668

Range A: Range G: Range B: Range C: Range D: Range E:
516 – 558
500 600 700 800
Each frequency range (A-E, G, GB) offers 26 frequency
banks with up to 24 channels each:
Each of the channels in the frequency banks “1” to “20”
has been factory-preset to a fixed transmission
frequency (frequency preset). 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 SKP 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.

Inserting the batteries/accupack
For powering the plug-on transmitter, you can either
use two 1.5 V AA size batteries or the rechargeable
Sennheiser BA 2015 accupack (optional accessory).
왘 Slide the battery compartment cover A in the direc-
tion of the embossed arrow and open the cover A.
왘 Insert the two batteries or the accupack as shown
below. Please observe correct polarity when inserting
the batteries/accupack.

왘 Close the battery compartment.
The battery compartment cover A locks into place
with an audible click.
Charging the accupack
왘 Remove the BA 2015 accupack.
왘 Insert the BA 2015 accupack into the L 2015 charger
(optional accessory).
The L 2015 charger can only charge the BA 2015
accupack. Standard batteries (primary cells) or
individual rechargeable battery cells cannot be
charged.

Plugging the plug-on transmitter onto a microphone
왘 Plug the microphone’s XLR-3M socket onto the XLR-
3F socket 1 of the transmitter. Make sure that the
latch B locks into place.
왘 Tighten the locking ring 2 in the direction of the
arrow.
The transmitter uses the microphone body as an
antenna – therefore microphones with a metal
casing should be used for best signal transmission.

Adjusting settings via the operating menu
The plug-on transmitter adds an inaudible pilot tone to
the audio signal. The receiver detects and evaluates the
pilot tone, and is thus able to identify the signal of the
matching transmitter and mute all others. The pilot
tone supports the receiver’s squelch function.
Adjusting the contrast of the display panel –
“LCD Contrast”
You can adjust the contrast of the display panel in
16 steps.

default settings, refer to the enclosed frequency information sheet.

Synchronizing the plug-on transmitter with a receiver
Synchronizing the plug-on
transmitter with a receiver
When synchronizing the plug-on transmitter with a
receiver, please observe the following:
왘 Only use a plug-on transmitter and a receiver
from the same frequency range (see the type
plates on the transmitter and the receiver).
왘 Make sure that the desired frequencies are
listed in the enclosed frequency information
sheet.
왘 Make sure that the desired frequencies are
approved and legal in your country and, if
necessary, apply for an operating license.
왘 Make sure that transmitter and receiver have at
least software version 1.7 (see page 22).
The most current software version is available
from your Sennheiser partner or can be downloaded from the SKP 300 G3 product page at
www.sennheiser.com.
Synchronizing the plug-on transmitter with the receiver – individual operation
Upon delivery, the plug-on transmitter and the receiver
are synchronized with each other. If, however, you
cannot establish a transmission link between plug-on
transmitter and receiver, you have to synchronize the
channels of the devices.
For information on automatic synchronization of the
plug-on transmitter with the receiver (individual operation), refer to the instruction manual of the receiver.
This information is marked with the icon.
Alternatively, you can set the channel on the plug-on
transmitter manually:
왘 Make sure that you set the plug-on transmitter to
the same frequency bank and the same channel as
the receiver (see page 18).
If you still cannot establish a transmission link, refer to
the chapter “If a problem occurs ...” on page 27.

Synchronizing plug-on transmitters with receivers – multi-channel operation
Combined with ew 300 G3 receivers, ew 300 G3 plug-on
transmitters can form transmission links that can be
used in multi-channel systems.
For information on automatic synchronization of plugon transmitters with receivers (multi-channel operation), refer to the instruction manual of your receiver.
For more information on multi-channel operation, visit
the SKP 300 G3 product page at www.sennheiser.com.

Cleaning and maintaining the
plug-on transmitter
CAUTION
Liquids can damage the electronics of the plug-on
transmitter!
Liquids entering the housing of the device can cause a
short-circuit and damage the electronics.
왘 Keep all liquids away from the plug-on transmitter.
왘 Do not use any solvents or cleansing agents.
왘 Use a cloth to clean the plug-on transmitter from
time to time.

Recommendations and tips
Recommendations and tips
... for the plug-on transmitter
• For best results, make sure that the transmitter
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 plug-on transmitter and receiving
antennas.
• To avoid overloading the receiver, observe a
minimum distance of 5 m between plug-on transmitter and receiving antennas.
• The plug-on transmitter uses the microphone body
as an antenna – therefore microphones with a
metal casing should be used for best signal transmission.
... for multi-channel operation
• When operating a multi-channel system, 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 transmitters simultaneously,
interference can be avoided by maintaining
a minimum distance of 20 cm between two
transmitters.
