Compression (settings 1 and 3)

Deterioration of the ability to hear quiet sounds as well as loud ones is a typical symptom of old age. Compression compensates for these volume differences by boosting the volume of quiet sounds and reducing the volume of loud sounds if necessary.

Compression seems to put the speech in the foreground, making it easier to understand.

Compression is self-regulating; once it has been activated, it is not necessary to make any other settings.

Treble boost (settings 2 and 3)

Another typical age-related phenomenon is the deterioration of the hearing with regard to high frequencies. However, high frequencies are important for the intelligibility of speech.

The treble boost makes the speech clearer and easier to understand.

With the treble boost (settings 2 and 3), additional fine adjustment is possible using the treble boost control G on the rear of the trans- mitter.

￿Use a screwdriver to turn the treble boost

control G to the left or right until the sound can be heard very well.

The position “0” corresponds to a minimum boost, the position “MAX” corresponds to a maximum boost, and the control is factory-

Gpreset to the medium position.

Function of the treble boost control

By means of the transmitter’s steplessly adjustable treble boost control G, the audio signal is boosted as shown in the diagram. The treble boost control G allows you to select one of the curves shown in the diagram below.
