General installation instructions for HELIX 
components

To prevent damage to the unit and possible injury, 
read this manual carefully and follow all installation 
instructions. This product has been checked for 
proper function prior to shipping and is guaranteed 
against manufacturing defects.

Before starting your installation, disconnect 
the battery’s negative terminal to prevent

 For 

a proper performance and to ensure full warranty 
coverage, we strongly recommend to get this prod-
uct installed by an authorized HELIX dealer.

Install your HELIX P SIX DSP MK2 in a dry loca-

RIWKHHTXLSPHQW7KHDPSOL¿HUVKRXOGEHVHFXUHG

to a solid mounting surface using proper mount-
ing hardware. Before mounting, carefully examine 
the area around and behind the proposed instal-
lation location to insure that there are no electrical  
cables or components, hydraulic brake lines or any 
part of the fuel tank located behind the mounting 
surface. Failure to do so may result in unpredictable 
damage to these components and possible costly 
repairs to the vehicle.

positive cable from the battery for the complete 
system should be provided with a main fuse at a 
distance of max. 30 cm from the battery. The val-

Prior to installation, plan the wire routing to 

 

avoid any possible damage to the wire harness. 
All cabling should be protected against possible 

 

crushing or pinching hazards. Also avoid routing 
cables close to potential noise sources such as 
electric motors, high power accessories and other 
vehicle harnesses.

Congratulations!

this input, we recommend to use an optional remote 

control.

ance of the speakers of the channels A and B must 

not be lower than 4 Ohms. All other channels can 

be loaded with a minimum of 2 Ohms.

Caution: 

Carrying out the following steps will re-

quire special tools and technical knowledge. In or-
der to avoid connection mistakes and / or damage, 
ask your dealer for assistance if you have any ques-
tions and follow all instructions in this manual (see 
page 13). It is recommended that this unit will be 
installed by an authorized HELIX dealer.

2.   Connecting the highlevel speaker inputs

 

The highlevel loudspeaker inputs can be con-
nected directly to the loudspeaker outputs of an 
OEM or aftermarket radio using appropriate ca-
bles (loudspeaker cables with 1 mm² / AWG 18 

max.). It is not mandatory to use all speaker 
inputs. Make sure that the polarity is correct. If 
one or more connections have reversed polarity

Important: 

To change the position of a jumper 

it has to be removed by pulling it straight up-
wards. Make sure that the jumper is reinsert-
ed properly and all pins are fully inserted. The 
position of each jumper can be changed inde-
pendently.

speakers to the outputs of the HELIX 
P SIX DSP MK2 during this setup.

2.  Adjust the volume of your radio to approx. 

90 % of the max. volume and playback a 
1 kHz full scale test tone (0 dB) via CD 
drive.

3.  The adjustment will be easier when you 

connect and adjust one input channel after 
each other.

4. If 

the 

Clipping LED

 already lights up, you 

have to reduce the input sensitivity via 
the respective potentiometer until the LED 
turns off.

 

If the potentiometer is already set to maxi-
mum CCW position then it will be necessary 
to change the sensitivity range by reposi-
tioning the internal jumper. 

5.  Increase the input sensitivity by turning the 

respective potentiometer clockwise until the 
LED lights up. Now turn the potentiometer 
counterclockwise until the 

Clipping LED

 

turns off again.

6.  Repeat this process for each channel pair 

you are using.

4.   Connecting a digital signal source

 

If you have a signal source with an optical digital

P SIX DSP MK2 automatically activates the 
used digital input if a digital audio signal is de-
tected. This function can be deactivated via the 
DSP PC-Tool software. Alternatively you can 
manually activate the digital input if you are us-
ing the optional remote control. The automatic 
turn-on circuit does not work when the digital in-
put is used. Therefore it is mandatory to connect 
the remote input (

Please note that it is possible to connect a 
source to the digital input and the highlevel or

Important: 

The signal of a digital audio source 

normally does not contain any information 
about the volume level. Keep in mind that this 
will lead to full level on the outputs of the HELIX 

36,;'630.DQG\RXUFRQQHFWHGDPSOL¿HUV

This may cause severe damage to your speak-
ers. We strongly recommend to use an optional 
remote control for adjusting the volume level of 
the digital signal input!

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 

IURPWKHEDWWHU\WRWKHDPSOL¿HUSRZHUWHUPLQDOV

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-

GLRV\VWHP36,;'630. PD[$506

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.

6.   Connecting the remote input

Installation with “Easy Plug Cable”

To simplify installation to an OEM or aftermar-
ket radio the HELIX P SIX DSP MK2 can also be 
connected using the optional Easy Plug Cable 
(EPC 5.2 - art.-no. HZ45000) which will supply the 

DPSOL¿HUZLWKWKHORXGVSHDNHUVLJQDOVRIWKHUDGLR

No factory wires or plugs need to be cut by using 
this connection method.
The Easy Plug Cable uses the highlevel inputs 
A - D. 

Note: Never use the power supply cables of the 
Easy Plug Cable. Always directly connect the 

PDVVLYH VFUHZ WHUPLQDOV RI WKLV DPSOL¿HU WR

your car’s battery using appropriate wires.

Connection to an OEM radio is detailed below:

1.   Once the radio has been removed by using the 

right tools disconnect the OEM harness from 
the radio. Connect the vehicle cable jack con-

nectors of the Easy Plug Cable. You may need 
a special ISO-adaptor depending on vehicle 
type. In order to varify please check the adaptor 
database on the Audiotec Fischer homepage

HELIX Extension Card slot (HEC slot)

It is possible to extend the functionality of the  HELIX 
P SIX DSP MK2 by inserting an optional HELIX 
 Extension Card (HEC) - for example a Bluetooth

®

 

Audio Streaming module, an additional optical digi-
tal input or an optical digital output. 
To install a HELIX Extension Card it is necessary to 

remove the bottom plate and one side panel of the 
P SIX DSP MK2 and replace it by the new side pan-
el that comes with the HEC. Any further mounting 
information will be found in the instruction manual 
of the respective HELIX Extension Card.

Start-/Stop capability

The switched power supply of the HELIX 
P SIX DSP MK2 assures a constant internal supply 
voltage even if the battery’s voltage drops to 6 Volts 
during engine crank.

Automatic Digital Signal Detection

Switching from analog input to the digital input is 
done automatically as soon as a signal is detect-
ed on the 

Optical Input

. This feature can be deac-

tivated in the DSP PC-Tool software. Alternatively 
you can use an optional remote control for manual 
switching between analog and digital inputs.
