The SKP 3000 plug-on transmitter
The SKP 3000 transmitter permits wireless transmission with
studio-quality sound. The use of further optimised PLL and
HiDyn
plus
microprocessor technology and the
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.
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
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 factorypreset 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,

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
noise reduction system that reduces RF interference. It increases
the signal-to-noise radio in wireless audio transmission to more
than 114 dB.
38
plus
the Sennheiser
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
HiDyn

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.

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
