User manual SENNHEISER SK 2013 PLL

[. . . ] If the instructor is not speaking, the hearing aid or the microphone built into the EK 2013 PLL is completely effective; now fellow students can be heard. Yet the dialogue between the instructor and the student is always given priority. The System 2013 PLL also remains a dependable aid under difficult conditions. The transmitting output reaches over great distances. [. . . ] Mono headphones must be equipped with stereo cinch plugs. Integrated antenna In both jacks the inserted cable is simultaneously used as an antenna. Operation on hearing aid with audio input The small jack (2. 5 mm dia. ) supplies the output signal for a hearing aid with an audio input. Hearing aid dealers carry suitable connection cables. (also see , , CABLES") Operation on hearing aid without audio input The , , Tele-Loop" ETZ 1011 or the Induction Disc EZI 120 for hearing aids without an audio input is connected to the large jack (3. 5 mm dia. ). Operation with headphones Stereo headphones (impedance > 32 ) are connected to the large jack. 2. 8 M S Lockable cover on receiver In order to reach the operating elements, a slide (S) is located on the right side of the unit. This protects the operating elements against unauthorized or accidental use. It is secured with a set screw (M), which is screwed in completely in order to open the slide. After removing the slide two potentiometers are accessible: · · The lower potentiometer (P1) adjusts the receiver volume, i. e. regulates the volume of the signal from the speaker. The upper potentiometer (P2) adjusts the basic volume of the built-in microphone. Automatic fade-in and microphone adjustment The receiver is equipped with an automatic fade-in feature. The connected hearing aid microphone or the microphone built into the receiver are turned down for the duration of speech transmission. This enables the signal of the speaker to be given preference at the wearer of the receiver. In addition, the automatic fade-in is complimented by a speech filter. As a result, disturbing noises (doors banging etc. ) do not trigger the automatic fade-in feature. The automatic fade-in and the basic volume of the faded-in microphone can be set separately. 2. 9 s1 1 23 4 1 23 4 s2 ON s Off e P2 P1 Off ON Setting automatic fade-in This adjustment is made exclusively by the hearing aid dealer!An adjuster (E) for the reduction depth of the automatic fade-in is located at the top behind a hole in the housing. Turning clockwise increases the reduction depth of the connected hearing aid microphones. Switching automatic fade-in and built-in microphone on/off This adjustment is made exclusively by the hearing aid dealer!Two toggle switches (S1/2) are accessible in the unit between the potentiometers for switching on the automatic fade-in and microphone. They can be actuated with a small screwdriver (2. 6 mm). · · If the switch (S2) is tipped toward the back of the unit, the automatic fade-in feature is switched on.
