Short instructions SKM 1072-U Inserting the battery adjusting the transmission frequency selecting the sensitivity switching on the transmitter

LOCKED Cleaning the sound inlet basket

Muting the microphone (N.B.: This operation does not switch off the transmitter.)

Inserting the battery Insert the battery as shown in the above figure.

Pay attention to the polarity ! Use only alkaline-manganese batteries or the approved accupack! Otherwise operating time (see technical data) will be drastically reduced. For frequent operation it is advisable to use the BA 1032 rechargeable accupack instead of batteries. BA 1032 accupack, charge in the L 1032 charging Unit The BA 1032 accupack is charged in the L 1032 charging unit. The charger requires the NT 1032 plug-in mains unit. One accupack can be charged in the microphone, a second spare accupack can be charged at the same time in the appropriate battery compartment of the charger. L 1032 and NT 1032 are available as accessories. The SKM 1072-U is connected to the L 1032 charger via charging contacts (see figure on next page).

Please take care that these contacts are clean. LED Adjusting the transmission frequency Adjust the desired transmission frequency with switch . Each number on the switch corresponds to a transmission frequency. The transmission frequencies are listed on the type plate in the battery compartment.

Make sure that transmitter and receiver operate on the same frequency.

Use a small screwdriver (width approx. 2 mm) for switching. Switching the transmitter on / selecting the sensitivity The ON/OFF switch and the sensitivity switch are recessed.

As the ON/OFF switch is used more often it is set slightly higher than the sensitivity switch. After switching on the transmitter you have to wait approx. 2 seconds as the transmitter requires this time for adjusting to the chosen frequency (PLL locked). After a short time, the red LED below the ON/OFF switch will light up. It serves as a pilot lamp and indicates: when it is lit: The battery is O.K. when it blinks: The battery is almost flat, it will only work for about another half an hour. A self-test has shown a defect. Please return the microphone to your local Sennheiser service department for repair.

When the sensitivity switch is set to “LOW”, the audio signal is attenuated, thus avoiding overmodulation when close-miking. Muting the microphone With switch 쐊 you can mute the microphone of the hand-held transmitter without switching off the transmitter itself. This avoids hissing noise in the receiver. The “ON” and “OFF” positions are clearly marked on the switch. Switch 쐊 can be locked in the ON position to avoid accidental switching (note the position of the screw head):

LOCKED Cleaning the sound inlet basket For cleaning, unscrew the sound inlet basket. Rinse the foam protection and the inlet basket with warm water, then dry with a hairdryer.

Only re-assemble the microphone when the inlet basket and the foam protection are completely dry! HiDynplus® noise reduction system The SKM 1072-U is fitted with the Sennheiser HiDynplus® noise reduction system. It can only work properly when the corresponding receiver also operates with HiDynplus®; otherwise the dynamic range will be greatly reduced and transmission will sound shrill.

If the SKM 1072-U is used as a hand-held transmitter the sensitivity should be switched to “ LOW”. For outdoor recordings and close-miking use the MZW 1032 windshield to reduce pop and wind noise.

If you want to wear the SKM 1072-U around your neck, use the supplied SZU 1032 lavalier clip as shown above. Set the sensitivity to “HIGH”. Fault Finding Fault Possible cause No function 왘 flat or weak battery battery inserted the wrong way round Acoustic feedback 왘 microphone is too close to the loudspeaker(s) 왘 receiver may not be equipped with HiDynplus® (The transmitter and receiver must both have the same noise reduction system. Receivers with a different noise reduction system will not only sound incorrect but also increase susceptibility to feedback. Make sure that the receiver is fitted with HiDynplus®.) No transmission though transmitter is switched on 왘 receiver and transmitter are switched to different frequencies Distortion 왘 sensitivity too high, sensitivity switch should be set to “LOW” when the SKM 1072-U is used as a hand-held microphone
