HiDyn plus noise reduction system ensure interference-free transmission. The transmitter can be supplied in nine frequency ranges within the UHF band. (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.)
• HiDyn plus noise reduction system • Signal-to-noise ratio > 114 dB(A) • Battery status indication with “LowBat” warning on the transmitter and transmission of “LowBat” warning to suitable receivers • Switchable 48 V phantom powering for powering condenser microphones •...
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.

Slide the cover of the battery compartment in the direction of the arrow until it clicks audibly and open the cover. Insert the 9 V PP3 battery (IEC 6 LR 61). Please observe correct polarity when inserting the battery. Close the battery compartment.
Plug the transmitter’s XLR-3 connector onto the micro- phone’s XLR-3 socket. Tighten the locking ring by hand. Note: The transmitter uses the microphone body as an antenna – there- fore only microphones with a metal casing should be used for best signal transmission.
Via the menu, switch off the phantom powering (P48) (u page 51). With the phantom powering switched on, the operating time of the battery will be reduced to approx. 5 hours. To switch the transmitter off, press the button until ON/OFF “OFF”...
Note: When switching on the transmitter with a partially used battery, it is possible that all eight segments may show for a short period of time – if this happens, re-check battery status after a few moments. LED lit up: The transmitter is switched on and the battery capacity is sufficient.

15 Selecting a frequency memory – selecting a frequency and channel number With the / buttons you can directly switch between the factory-preset fixed frequency memories (presets). The display starts flashing. Your selection becomes effective immediately. Press the button to acknowledge your selection. The display stops flashing.
With the / buttons you can now select a different setting. The sensitivity can be adjusted in 10-dB steps from 0 to –30 dB. The new setting starts flashing on the display and becomes effective immediately.
Select the “Att” menu by pressing the button until “Att” appears on the display; after a short pause the current setting – i.e. “Att OFF” or “Att On” – is displayed. With the / buttons you can now switch between two different sensitivity ranges.

Select the frequency memory for which you wish to set a frequency (u “15 Selecting a frequency memory –...
Assigning a channel number (Ch no) You can now assign each frequency memory a channel number (from 0 to 255). With larger systems, we recommend using the same channel numbers for both transmitters and receivers in order to provide for simpler monitoring of the system.
“LOC On” starts flashing on the display. Press the button to return to the top menu level. Note: If you press the / buttons or the button, “LOC On” ON/OFF appears on the display and the buttons are now locked.
