With the loud speaker switch box AC 5120 the audio output of the vehicle speaker is transmitted. With this, the installation of an additional speaker is avoided. When the car radio has no speaker mute function, then the switch box performs this. For telephone conversations in hands-free mode the radio is therefore automatically muted.
The switch box uses one or two of the car radio speakers, even when this is not switched on. These functions become automatically active during the installation and do not need to be additionally operated or selected.
