Sennheiser Microphone Care and maintenance, Adjusting the squelch threshold, Selecting a channel

Adjusting the squelch threshold

Interference due to other transmission links can be eliminated as follows:

￿Switch off the transmitter. The receiver should no longer receive a signal.

￿ If the receiver still receives a signal, use the SQUELCH control to increase the squelch threshold so that the signal will no longer be received. If the signal cannot be eliminated in this way, set the transmitter and the receiver to a different channel.

￿Switch on the transmitter again and check if the receiver receives the transmitter signal.

Note:

If the squelch threshold is adjusted too high, the transmission range will be reduced. Therefore, always adjust the squelch treshold to the lowest possible setting.

Selecting a channel

Transmitters and receivers have four channels respectively with intermodulation-free frequencies.

Note:

These frequencies are different to those in evolution systems and freePORT systems should not be used together with evolution sys- tems without great care.

￿Always set the transmitter and the receiver to the same channel.

Adjusting the transmitter sensitivity

￿ Use the GAIN control on the SK 2 bodypack transmitter to adjust the sensitivity so that even during the loudest passages the AF PEAK LED on the EM 1 receiver does not light up.

Care and maintenance

Use a slightly damp cloth to clean the units from time to time.

Note:

Do not use any cleansing agents or solvents.

To clean the SKM 3’s sound inlet basket:

￿ Unscrew the sound inlet basket (turn counterclockwise) and remove it.

￿Remove the foam insert and use a slightly damp cloth to clean the sound inlet basket.

￿Reinsert the dry foam insert, replace the sound inlet basket on the SKM 3 and screw it tight.
