The
HIGH LEVEL INPUT
is suitable to connect the speaker outputs of the head unit, if no pre-amplifier RCA outputs are available.
Please use the include wire harness for the connection. Please observe and ensure the correct polarity of all connections.
NEVER
use the High Level Input and the RCA inputs at the same time. This may damage the sound system seriously.
The
LOW LEVEL INPUT RCA jacks
must be connected with the RCA output jacks of the headunit. This input is only suited for low
level signals.
Always ensure the correct polarity of all connections. The interchange of plus and minus cause total loss
of bass playback and could damage the speakers.
