Subwoofer Output
This output provides the connection of a
passive Plug & Play subwoofer. When using a
subwoofer we recommend to connect the power
supply of the PP20 DSP according to
fi
gure 4b.
Remote
The Remote connector can be used as an input
or an output.
If the PP20 DSP cannot be switched on via the
radio, you can use the 6.3mm blade terminal as
input. Using it as an output, you can control further
external devices with this blade terminal, such as
an active subwoofer.
HELIX Plug & Play Connector
The connector has to be used for connecting the
provided cable harness. Please use the provided
HELIX cable for this connection exclusively!
Cau-
tion: The use of other or similar cables can re-
sult in the damage of the ampli
fi
er, of the head
unit / radio or the connected loudspeakers!
