Information:
The HELIX P SIX DSP can only
handle uncompressed digital stereo signals in
PCM format with a sample rate between 12 kHz
and 96 kHz. Neither Dolby-coded signals 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!
Connect the +12V power cable to the positive
terminal of the battery. The positive wire from
the battery to the amplifier power terminals
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
-
dio system. If your power wires are short (less
than 1 m / 40”) then a wire gauge of 16 mm² /
AWG 6 will be sufficient. In all other cases we
strongly recommend gauges of 25 - 35 mm² /
AWG 4 – 2! The ground cable (same gauge
as the +12V 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.
6. Connecting the remote input
The remote input has to be connected to the
radio remote output if the amplifiers pre-ampli
-
fier inputs are used as signal inputs. We do not
recommend controlling the remote input via the
ignition switch to avoid pop noise during turn on/
off.
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.
7. Connecting the remote output
This output is used to supply remote signals to
the external amplifier/s. Always use this remote
output signal to turn on the amplifiers in order to
avoid on/off switching noises.
