8. 2. Reproduction over an external loudspeaker
In the following cases, an external loudspeaker (4 Ω , min. 5W) must be
employed:
• If loudspeakers of the car radio should not be employed
• If the output power of the loudspeaker channel exceeds 35 W (sine) and no
telephone connection to the car radio is provided
• If the car radio is operated with active boxes and no telephone connection to
the car radio is provided.
Feedback loops disturb the intelligibility. Place the external loudspeaker at a
distance of at least 80 cm from the microphone. For fixing the external loudspea-
ker, note the references of the respective manufacturer. The loudspeaker con-
trols can be connected to the white (Pin 2) and black/white (Pin 14) lines of the
connecting cable. Before this, the line is to be separated from the ISO plug con-
nector.
