The SKP 3000 plug-on transmitter
The SKP 3000 transmitter permits wireless transmission with
studio-quality sound. The use of further optimised PLL and
microprocessor technology and the HiDyn
plus noise reduction
system ensure interference-free transmission.
The transmitter can be supplied in nine frequency ranges within
the UHF band and with a frequency grid of 5 kHz. 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.
The plug-on transmitter has two channel banks with up to 20
switchable channels each.
The channels of the channel bank “FIX” (Fixed Bank) are factory-
preset to customer specific transmission frequencies. These
transmission 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 “VAR” (Variable Bank) allows you to store
your selection of transmission frequencies that are freely
selectable within the preset frequency range. Please note,
Range Frequency range Range Frequency range
A 518 to 554 MHz F 556 to 592 MHz
B 626 to 662 MHz G 576 to 612 MHz
C 740 to 776 MHz H 670 to 706 MHz
D 786 to 822 MHz I 696 to 732 MHz
E 830 to 866 MHz

38
however, that the channel bank “VAR” is factory-preset to the
same frequencies as the channel bank “FIX”.
The transmitter can be combined with the rack-mount and
bodypack receivers of the 3000 and 5000 series (e.g. EM 3252,
EM 3032, EM 3031, EK 3041, EM 1046).
The balanced XLR input allows the connection of
!dynamic microphones,
!condenser microphones with internal power supply and
!condenser microphones that require 48 V phantom powering.
HiDyn plus noise reduction
This transmitter is equipped with HiDyn plus the Sennheiser
noise reduction system that reduces RF interference. It increases
the signal-to-noise radio in wireless audio transmission to more
than 114 dB.

39
HiDyn plus is a wideband compander system which compresses
the audio signal in the transmitter in a ratio of 2:1 (related to
dB). In the receiver the signal is expanded in an identical and
opposite way in a 1:2 ratio to restore the original signal.
HiDyn plus has been specially developed for high quality
radiomicrophone systems.
Note:
Only transmitters and receivers that are equipped with
HiDyn plus can work correctly with each other. If non
HiDyn plus equipment was mixed with HiDyn plus , the
dynamic range would be drastically reduced and the
transmission would sound blunt and flat. HiDyn
plus is
permanently active and cannot be switched off.

Putting the SKP 3000 into operation
Inserting and replacing the batteries
For powering the plug-on transmitter, you can either use two
1.5 V AA size batteries or the rechargeable Sennheiser BA 2015
accupack.
Note:
For accupack operation of the transmitter, only use the
BA 2015 accupack in order to ensure optimum operational
reliability. Batteries and rechargeable battery cells have
different discharging curves. The transmitter is able to
identify the BA 2015 accupack and to use its capacity to the
Slide the battery compartment
cover in the direction of the
embossed arrow until it clicks audibly
and open the cover.
Insert the two batteries or the BA 2015
accupack as shown below. Please
observe correct polarity when inserting
the batteries/accupack.
Close the battery compartment. The
battery compartment cover locks
into place with an audible click.

full. The transmitter adapts the battery status display
according to the type of power supply used (batteries or
accupack) and ensures correct transmission of battery status
information to the receivers. Individual rechargeable battery
cells will not be identified as accupacks.
Plugging the plug-on transmitter onto a microphone
Note:
The transmitter uses the microphone body as an antenna –
therefore only microphones with a metal casing should be
used for best signal transmission.
Unscrew the locking ring  by turning
it fully counter-clockwise (XLR-3 socket
is unlocked).
Plug the transmitter’s XLR-3F socket 
onto the microphone’s XLR-3M socket.
Tighten the locking ring by turning it
clockwise (in the direction of the
arrow).

Switching the plug-on transmitter on/off
Note:
Within the operating menu, the ON/OFF button serves as the
ESC (cancel) key (see “Exiting the operating menu” on
page 49).
Remove the batteries or the accupack when the transmitter
will not be used for extended periods of time.
Muting the plug-on transmitter
Activating/deactivating the lock mode
The lock mode prevents that the transmitter is accidentally
programmed or switched off during operation (see
“Activating/deactivating the lock mode – LOCK” on page 55).
Press the ON/OFF button to switch
the transmitter on. The red LED 
lights up.
To switch the transmitter off, press the
ON/OFF button until “OFF” appears
on the display. The red LED goes off.
The transmitter has a MUTE switch that
noiselessly mutes the audio signal without
switching the transmitter off. The “MUTE”
display appears on the display panel.

Adjustment tips for the operating menu
Switching between channel banks – BANK
Via the “BANK” menu, you can switch between the two channel
banks. The channels of the channel bank “FIX” (Fixed Bank) are
factory-preset to customer specific transmission frequencies.
These frequencies cannot be changed.
The channel bank “VAR” (Variable Bank) allows you to store
your selection of transmission frequencies that are freely
selectable within the preset frequency range. Please note that
the channel bank “VAR” is factory-preset to the same
frequencies as the channel bank “FIX”.
When switching from one channel bank to the other, the channel
with the lowest channel number is automatically displayed.
Switching between the channels in a channel bank – CHAN
Via the “CHAN” menu, you can switch between the up to 20
channels in a channel bank.
Selecting the frequencies to be stored in the channel bank
“VAR” – TUNE
Via the “TUNE” menu, you can select the frequencies to be
stored in the channel bank “VAR” (Variable Bank).
When you select the “TUNE” menu, the channel set briefly
appears on the display and then the last frequency stored is
displayed. When you have selected the channel bank “FIX” and
then select the “TUNE” menu, the transmitter automatically
switches to channel 01 of the channel bank “VAR” and “VAR”
briefly appears on the display.
