User manual SENNHEISER SI 29-5

[. . . ] 04004 AF inputs Five XLR input sockets for connection of five mono audio signal sources are located at the back of the SI 29-5 infra-red modulator. In addition, all inputs are available at the 25-pin D-connector . For the connection details of this connector please see the service manual. 9 Connecting IR radiators Connect the infra-red radiators to sockets . [. . . ] With the "+" button you choose a higher input number. Holding this button down initiates fast search, continually cycling from the beginning. With the "-" button you choose a lower input number. Holding this button down initiates fast search, continually cycling from the beginning. When both buttons are released the selected input is stored. Now you have to choose the infra-red transmission channel for the selected input. Choosing the IR transmission channel Switching a channel off By simultaneously pressing the buttons "CHANNEL" and "+" or "-" you start the search for the infra-red transmission channel which is to be assigned to the input. To switch a channel off, search through the transmission channels as described above. The OFF position is the next channel above "£ ¡" or below "ºº" (depending which way you go). The display will indicate "ºF. " instead of a channel number and the corresponding LED will go off. NB: It is important that any unused channels are switched off. Any channel left on, but unused, will reduce the radiator coverage area accordingly. (See the section on calculating the radiator coverage area in the user manual supplied with the radiator). 12 Adjusting the AF level By simultaneously pressing the buttons "AF LEVEL" and "+" or "-" you can adjust the AF level for the transmission channel you have just selected. With the "+" button you increase the AF level. With the "-" button you decrease the AF level. The level is adjusted correctly when the modulation indicator nally reaches the red part of the display (full modulation). When both buttons are released, the selected AF level is stored. This completes all settings for the first audio input channel.
