Information: The HELIX P SIX DSP MK2 can
only handle uncompressed digital stereo sig-
nals in PCM format with a sample rate between
12 kHz and 96 kHz. Neither Dolby-coded sig-
nals nor compressed MP3-/WMA- or AAC-audio
formats will be accepted.
5. Connection to power supply
Make sure to disconnect the battery before
installing the HELIX P SIX DSP MK2!
Connect the +12 V / 24 V power cable to the
positive terminal of the battery. The positive wire

needs to have an inline fuse at a distance of
no more than 12 inches (30 cm) from the bat-
tery. The value of the fuse is calculated from the
maximum total current input of the whole car au-

at 12 V RMS, max. 30 A RMS at 24 V power
supply). If your power wires are short (less than

ly recommend gauges of 25 - 35 mm² / AWG
4 – 2! The ground cable (same gauge as the
+12 V / +24 V wire) should be connected to a
common ground reference point (this is locat-
ed where the negative terminal of the battery is
grounded to the metal body of the vehicle), or to
a prepared metal location on the vehicle chas-
sis, i.e. an area which has been cleaned of all
paint residues.

If the Highlevel Inputs are used this input does
not need to be connected as long as the car ra-
dio has BTL output stages.
