General instructions

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 guaran-teed against manufacturing defects.

Before starting your installation, disconnect the battery’s negative terminal to prevent damage to the unit, fire and / or risk of injury. For a proper performance and to ensure full warranty coverage, we strongly recommend to get this product installed by an authorized HELIX dealer.

Install your HELIX P SIX DSP ULTIMATE in a dry location with sufficient air circulation for proper cooling of the equipment. The amplifier should be secured to a solid mounting surface using proper mounting hardware. Before mounting, carefully examine the area around and behind the pro-posed installation location to insure that there are no electrical cables or components, hydraulic brake lines or any part of the fuel tank located be-hind the mounting surface. Failure to do so may result in unpredictable damage to these components and possible costly repairs to the vehicle.

General instruction for connecting the HELIX P SIX DSP ULTIMATE amplifier
The HELIX P SIX DSP ULTIMATE amplifier may only be installed in vehicles which have a 12 / 24 Volts negative terminal connected to the chassis ground. Any other system could cause damage to the amplifier and the electrical system of the vehicle.
The 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 value of the fuse is calculated from the maximum total current input of the car audio system.

Use only suitable cables with sufficient cable cross-section for the connection of HELIX P SIX DSP ULTIMATE. The fuses may only be replaced by identically rated fuses (3 x 20 A) to avoid damage of the amplifier.

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.

Hardware configuration

Configure the HELIX P SIX DSP ULTIMATE as follows
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 questions and follow all instructions in this manual (see page 17). It is recommended that this unit will be installed by an authorized HELIX dealer.

1. Setting the input voltage range (“VoltageRange”) of the analog signal inputs ATTENTION: When using the analog in-puts (lowlevel & highlevel) as signal in-put, it is mandatory to adjust the “Voltage Range” to the output voltage of the signal source before the first start up in order to avoid damage to the amplifier.
   At first, the “Voltage Range” of the analog in-puts has to be set inside the device. Remove the bottom plate by loosening the 10 Allen screws. Now you have access to the jumpers (see fig. 1). Each jumper sets the value range for the corresponding input channels (J1 –channel A – D and J2 – channel E – F).
   If you want to connect a conventional OEM or aftermarket radio as signal source, the jumper must be set to “Low Voltage Range” (Line 1 -4 V / Highlevel 4 – 16 V). This range is preset by default, see fig. 2.
   If you want to connect a factory-installed amplifier as signal source, we recommend to determine its maximum output voltage previously with a suitable measuring device or to contact your authorized HELIX dealer. If you are not sure, we recommend to set the jumper to “High Voltage Range” (Line 2 – 8 V / High level 8 -32 V) to avoid possible damage to the device. Therefore, both jumpers have to be repositioned to the factory unused multi-pin connector, see fig. 3. Overview jumper plug-in positions:
   Jumper 1 (J 1): Channel A – D
   Jumper 2 (J 2): Channel E – F
   For repositioning a jumper simply pull it up-wards and plug it into the desired plug position.
   Make sure that the jumper is reinserted properly and all pins are fully inserted. Low Voltage Range configuration (by default):
   Value range: Highlevel 4 – 16 Volts
   RCA / Cinch 1 – 4 Volts High Voltage Range configuration:
   Value range: Highlevel 8 – 32 Volts
   RCA / Cinch 2 – 8 Volts
   After setting the jumpers to the desired plug-in positions, you can reassemble the amplifier.

2. Connecting the pre-amplifier inputs
   These six lowlevel line inputs can be connect-ed to signal sources such as head units / radios using appropriate cables. Each input can be assigned to any output using the DSP PC-Tool software. Input sensitivity is factory-set to 4 Volts for all channels. But it is possible to optimally adapt the input sensitivity to the signal source (see page 22, point 8).
   The automatic turn-on circuit does not work when using the pre-amplifier inputs. In this case the remote input has to be connected to activate the HELIX P SIX DSP ULTIMATE. Important: It is strictly forbidden to use the Highlevel and lowlevel Line Input of an individual channel at the same time as this may cause severe damage to the lowlevel line out-puts of your head unit / car radio. Neverthe less it is possible to use the Highlevel Input of one channel and the lowlevel Line Input of another channel simultaneously.

3. Connecting the highlevel speaker inputs
   The six highlevel loudspeaker inputs can be connected directly to the loudspeaker out-puts of an OEM, aftermarket radio or factory installed amplifier using appropriate cables (loudspeaker cables with 1 mm² / AWG 18 max.).
   We recommend the following channel assignment if a common car radio will be connected to the amplifier:
   Channel A = Front left
   Channel B = Front right
   Channel C = Rear left
   Channel D = Rear right
   Actually it is not mandatory to use all high level speaker inputs. If only two channels will be connected we recommend to use the chan-nels A and B. Make sure that the polarity is correct. If one or more connections have re-versed polarity it may affect the performance of the amplifier. If this input is used the remote input does not need to be connected as the amplifier will automatically turn on once a loudspeaker signal is received.
   Input sensitivity is factory-set to 16 Volts for all channels. It is possible to optimally adapt the input sensitivity to the signal source (see page 22, point 8).
   Attention: Solely use the pluggable screw-terminals for the highlevel connector which are included in delivery!
   Important: It is strictly forbidden to use the High level and lowlevel Line Input of an individual channel at the same time as this may cause severe damage to the lowlevel line out-puts of your car radio.
   Nevertheless it is possible to use the Highlevel Input of one channel and the lowlevel Line In-put of another channel simultaneously.

4. Connecting a digital signal source in SPDIF format
   If you have a signal source with a coaxial or optical digital output you can connect it to the amplifier using the appropriate input. The sampling rate must be between 12 and 96 kHz for the Optical Input and 12 – 192 kHz for the Coax Input. The input signal is automatically adapted to the internal sample rate.
   In standard configuration the Optical Input is activated as well as the manual activation via an optional remote control is configured. Alternatively you can activate the automatic turn-on feature in the DCM menu of the DSP PC-Tool software.
   The automatic turn-on circuit does not work when a digital input is used. Therefore it is mandatory to connect the remote input. 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 P SIX DSP ULTIMATE and your connected amplifiers. This may cause severe damage to your speakers. We strongly recommend to use an optional remote control for adjusting the volume level of the digital signal input!
   Note: The HELIX P SIX DSP ULTIMATE can only handle uncompressed digital stereo signals in PCM format with a sample rate be-tween 12 kHz and 96 kHz / 192 kHz and no MP3- or Dolby-coded digital audio stream!

5. Configuration of the remote input
   The P SIX DSP ULTIMATE will be turned on automatically if the Highlevel Input is used or if a signal is applied to the remote input terminal. The Auto Remote switch (page 18, point 14) allows to deactivate the automatic turn-on feature of the highlevel inputs. The feature should be deactivated if there are e.g. noises while switching on / off the amplifier. On: Activation via highlevel speaker input is enabled (by default).
   Off: Activation via highlevel speaker input is disabled.
   Note: If the automatic turn-on function is de-activated it is mandatory to use the remote input terminal to power up the amplifier! The highlevel signal will be ignored in this case.

6. Connection to power supply & remote
   Make sure to disconnect the battery before installing the HELIX P SIX DSP ULTIMATE! Make sure of correct polarity. + 12V: Connector for the positive cable. Con-nect the +12 V / 24 V 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 battery. The value of the fuse is calculated from the maximum total current input of the whole car audio system (P SIX DSP ULTIMATE = max. 60 A RMS at 12 V RMS, max. 30 A RMS at 24 V power supply). 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! GND: Connector for the ground cable.
   The ground wire should be connected to a common ground reference point (this is located 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 chassis, i.e. an area which has been cleaned of all paint residues. The cable should have the same gauge as the +12 V / +24 V wire. Inadequate grounding causes audible interference and malfunctions.
   REM: The remote input is used to switch on the P SIX DSP ULTIMATE if the pre- amplifier or digital inputs are used. Additionally, this input must be assigned, if the signal source which is connected to the Highlevel Input is not activating the “automatic turn-on” function or if the amplifier shall only be activated / de-activated via a remote signal. The remote wire should be connected to the remote output / automatic antenna (aerial positive) output of the head unit / car radio. This is only activated if the head unit is switched on. Thus the amplifier is switched on and off together with the head unit.
   We do not recommend controlling the remote input via the ignition switch to avoid pop noise during turn on / off.
   Note: This input does not need to be assigned if the Highlevel Input is used. To deactivate the “automatic turn-on” function read the description in point 5 “Configuration of the remote input”.

7. Connecting the PC & first start-up
   The USB input enables the connection of the P SIX DSP ULTIMATE to a personal computer and its free configuration with our DSP PC-Tool software using the provided USB cable.
   Please note: It is not possible to connect any USB storage devices.
   Prior to connecting the amplifier to your PC visit our website and download the latest version of the DSP PC-Tool software.
   We strongly recommend to carefully read the DSP PC-Tool knowledge base before using the software for the first time in order to avoid any complications and failures.
   Important: Make sure that the amplifier is not connected to your computer before the soft-ware and USB driver are installed!
   In the following the most important steps how to connect and the first start- up are described:

8. Download the latest version of the DSP PC-Tool software (available on our website www.audiotec-fischer.com) and install it on your computer.

9. Connect the amplifier to your computer using the USB cable that is included in delivery. If you have to bridge longer distances please use an active USB extension cable with integrated repeater.

10. First turn on the amplifier and then start the software. The operating software will be updated automatically to the latest version if it is not up-to-date.

11. Adjustment of the input sensitivity of the analog signal inputs
    ATTENTION: It is mandatory to properly adapt the input sensitivity of the P SIX DSP ULTIMATE to the signal source in order to achieve the best possible signal quality and to avoid damage to the amplifier. It is also mandatory to adjust the “Volt-age Range” to the output voltage of your signal source (see page 19, point 1).
    The input sensitivity of each channel pair can be optimally adapted to the signal source using the three gain controls. The setting of the controls affects both the lowlevel and the highlevel inputs!
    Input sensitivity is factory set to 16 Volts (high-level) and 4 Volts (RCA / Cinch). This is definitely the best setting in most applications.
    The gain control ranges are:
    Low Voltage Range configuration: Highlevel: 4 – 16 Volts
    RCA / Cinch: 1 – 4 Volts
    High Voltage Range configuration: Highlevel: 8 – 32 Volts
    RCA / Cinch: 2 – 8 Volts
    If the signal source provides a lower output voltage, the input sensitivity can be smoothly increased via the controls.
    If your signal source delivers a higher output voltage – for example, if a factory-installed amplifier serves as signal source – the input sensitivity must be lowered via the controls and the correct configuration of the “Voltage
    Range” jumpers must be checked.
    If you are not sure regarding the signal sources output voltage, please contact your HELIX specialist dealer.
    The Clipping LED (see page 18, point 8) serves as monitoring tool.
    Note: Don‘t connect any amplifiers or loudspeakers to the outputs of the HELIX P SIX DSP ULTIMATE during this setup.
    For fine adjustment please proceed as fol-lows:

12. Turn on the amplifier.

13. Adjust the volume of your radio to approx. 90 % of the max. volume and playback an appropriate test tone, e.g. pink noise (0 dB).

14. If the Clipping LED already lights up, you have to reduce the input sensitivity via the appropriate gain control (see image left side) until the LED turns off.

15. Increase the input sensitivity by turning the gain control clockwise until the Clipping LED lights up. Now turn the control counter clockwise until the Clipping LED turns off again.

16. Repeat this process for each channel pair you are using.
    Various adjustment examples of the input sensitivity can be found on page 24. For further applications please contact your HELIX specialist dealer.

17. Configuration of the internal DSP The general DSP settings should be con-ducted with the DSP PC-Tool software be-fore using the amplifier for the first time.
    Now you are able to configure your P SIX DSP ULTIMATE with our intuitive DSP PC-Tool software. Useful hints for the correct setting can be found in our knowledge base at www.audiotec-fischer.com.
    Caution: We highly recommend to set the volume of your car radio to minimum position during first start-up. Additionally no devices should be connected to the amplifier. Especially if the P SIX DSP ULTIMATE will be used in fully active applications, a wrong setup can destroy your speakers right away.

18. 10. Analyzing the input signal
    Check the input signal for factory-set equal-izing and all-pass filters using the Input Signal Analyzer (ISA) of the DSP PC-Tool software. Information about the ISA can be found in the extensive Knowledge Base on our website www .audiotec-fischer.com. Caution: We highly recommend to set the volume of your car radio to minimum position during first start-up. Additionally no de-vices should be connected to the amplifier until general settings in the DSP PC-Tool software have been made. Especially if the P SIX DSP ULTIMATE will be used in fully active applications, a wrong setup can destroy your speakers right away.

19. Connecting the loudspeaker outputs The loudspeaker outputs can be connect-ed directly to the wires of the loudspeakers. Never connect any of the loudspeaker cables with the chassis ground as this will damage your amplifier and your speakers. Ensure that the loudspeakers are correctly connected (in phase), i.e. plus to plus and minus to minus. Exchanging plus and minus causes a total loss of bass reproduction. The plus pole is indicated on most speakers. The impedance 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. The speaker outputs are not bridgeable. For sub-woofer applications please use drivers with dual voice coil.

20. Connecting the remote output
    The remote output is used for turning on / off amplifiers that are connected to the Line Outputs or Optical Output of the HELIX P SIX DSP ULTIMATE. Therefore connect the remote output to the remote inputs of your amplifiers to switch them on and off via the P SIX DSP ULTIMATE without interfering signals. The remote output is activated auto-matically as soon as the booting process of the internal DSP is completed. Additionally this output will be turned off during the “Power Save Mode” or a software update process. Important: Never use a different signal than the remote output of the amplifier to activate connected amplifiers!

21. Connecting the Line Outputs
    The four pre-amplifier outputs (Line Output) can now be connected to the pre- amplifier /lowl evel / RCA inputs of the external amplifiers using appropriate cables (RCA / Cinch cables).

22. Connecting the optical digital output The Optical Output is an optical, digital stereo signal output in SPDIF format for connecting an additional amplifier with optical digital input. The output has a sampling rate of 96 kHz / 24 Bit and provides a volume-con-trolled signal.
    Note: The output provides a stereo signal only. Fader information and multi- channel sur-round sound formats like Dolby or DTS are not supported!

23. Sound tuning
    Now you can create your sound setup. Information about sound tuning can be found in our extensive knowledge base at audiotec-fischer.com or contact your local HELIX dealer.

Additional functions

1. Clipping LED
   Normally the Clipping LED is off and only lights up if one of the Line or Highlevel Inputs is overdriven.
   On (red): One of the analog signal inputs is overdriven. Reduce the input sensitivity using the three gain controls until the LED goes out. How to reduce the input sensitivity is de-scribed on page 21 point 8.
   Note: The LED has no function when using one of the digital inputs.

2. Status LED
   The Status LED indicates the operating mode of the amplifier and of its memory.
   Green: Amplifier is ready for operation. Orange: Power Save Mode is active.
   Red: Protection Mode is active. This may have different root causes. The HELIX P SIX DSP ULTIMATE is equipped with protection circuits against over- and under voltage as well as overheating. Please check for connecting failures such as short-circuits or other wrong connections. If the amplifier is overheated the internal temperature protection switches off the remote and signal output until it reaches a safe temperature level again. Red / green slow flashing: No operating soft-ware installed. Connect the amplifier to the DSP PC-Tool software and confirm the automatic update of the operating system. You will find the latest version of the DSP PC-Tool software at www.audiotec- fischer.com.
   Red / green fast flashing: The currently selected sound setup memory is empty. A new setup has to be loaded via the DSP PC-Tool software or switch to a memory position with existing sound setup.

3. Control pushbutton
   The P SIX DSP ULTIMATE provides 10 internal memory locations for sound setups. The Control pushbutton allows the user to switch between two memory positions. These can be defined in the DSP PC-Tool. In addition a de-vice reset can be made by pressing the button for a longer period.

4. Setup switch: Press Control pushbutton for 1 second. The memory locations one and two are defined by default. Switching is indicated by a single red flash of the Status LED. Alternatively, the optional URC.3 remote control can be used for switching. To switch between all internal memory locations, optional accessories like the DIRECTOR display remote control or CONDUCTOR are required.

5. Device reset: Press pushbutton for five seconds. This completely erases the internal memory and is indicated by a continuous red glowing and constant green flashing of the Status LED.
   Attention: After erasing the setups from memory the P SIX DSP ULTIMATE will not reproduce any audio output until the device is updated via the DSP PC-Tool software.

6. SCP (Smart Control Port)
   This multi-functional input is designed for HELIX P SIX DSP ULTIMATE accessory products like a remote control which allows to adjust several features of the amplifier. Depending on the type of remote control, at first its functionality has to be defined in the “ Device Configuration Menu” of the DSP PC-Tool software.
   Attention: If the accessory product does not have a NanoFit connector solely use the NanoFit adaptor which is included in delivery for connection.

Virtual Channel Processing (VCP)

In addition to standard routing, the HELIX P SIX DSP ULTIMATE offers Virtual Channel Processing (VCP), a multi-stage signal processing concept that enables the perfect configuration of complex sound systems, opening up completely new possibilities for sound tuning.

The VCP extends the previous scope of the device by an additional layer of processed channels, which is located between the inputs and outputs. A total of eight additional processed virtual channels and 12 processed output channels are available.

This virtual channel layer offers several advantages, especially in complex system configurations.

The main advantages of this concept are:

• Cross-channel group equalizers that affect several output channels simultaneously
• Multi-way speaker configuration of DSP sound effects (SFX)
• Additional features such as Rear Attenuation

For further information about the VCP and its configuration, please refer to our Knowledge Base at www.audiotec-fischer.com.

Configuration of a subwoofer remote control

In order to configure a subwoofer remote control, specific settings have to be made in the DSP PC-Tool. First, the appropriate remote control must be activated in the “Extended Features” tab in the DCM menu of the DSP PC-Tool software and configured, depending on the model. If the VCP is not activated, the subwoofer remote control of the P SIX DSP ULTIMATE is permanently assigned to the output channels E and F. In this case it does not matter which output is named “Sub-woofer” in the IO routing matrix.
In the “Outputs” menu you can also see to which outputs the SubRC (subwoofer remote control) is tied: When VCP is activated, the subwoofer remote control is tied to the output channels that are supplied with one of the two virtual subwoofer signals (“Subwoofer 1” or “Subwoofer 2”) in the “Virtual to Output Routing” matrix. This can be any combination of output channels.

In the following example these are the amplifier outputs G and H: Note: Please note that an input signal must be assigned to the two virtual subwoofer signals “ Subwoofer 1” and / or “Subwoofer 2” in the other routing matrices.
Afterwards, the subwoofer control is also displayed in the “Outputs” menu next to the name of the chan-nel [SubRC]:

ACO platform features

Beside the unique DSP sound effects the P SIX DSP ULTIMATE provides a bunch of new system and DSP features.
In the DCM menu of the DSP PC-Tool software individual settings can be made for several of these system features.

Turn On & Off Delay
This function allows to determine the delay time with which the integrated DSP is switched on and off. The factory setting is 0.2 seconds. The delay time should only be modified if there are e.g. noises while switching on / off the amplifier.

URC Setup Switch Configuration
The ACO provides ten internal memory locations for sound setups instead of the common two.
By using an optional URC remote control or the Control pushbutton (see page 18, point 1) it is possible to toggle between two of the ten mem-ory locations. These two memory locations can be determined in the “URC Setup Switch Config-uration”. The memory locations one and two are preassigned by default. To switch between all in-ternal memory locations, the optionally available remote controls DIRECTOR and CONDUCTOR are recommended.

Remote Output Configuration
This function controls if the remote output (which switches on and off the connected amplifiers) will be temporarily deactivated during a sound setup switch. This function is activated (ON) by default.

ADEP.3 Configuration
If the P SIX DSP ULTIMATE is connected to an OEM radio via the highlevel inputs it may happen that the ADEP.3 circuit has to be adapted to the di- agnostic mode of the radio if the latter is equipped with a so-called “class SB” output stage”.
In the “ADEP.3 SB compatibility mode & Advanced Noise Suppression” section, an adjustment should be made if there are e.g. distortions occur in the upper volume range.
The compatibility mode is disabled by default.

HELIX Extension Card slot (HEC slot)

It is possible to extend the functionality of the HELIX P SIX DSP ULTIMATE by inserting an optional HELIX Extension Card (HEC) – for example a High Definition Bluetooth® Audio Streaming module, a High Resolution Audio USB soundcard etc.
To install a HELIX Extension Card it is necessary to remove the side panel of the P SIX DSP ULTIMATE and replace it by the new side panel that comes with the HEC module.

Attention: Install the HEC module only in the designated device and its specific slot. Using the HEC module in other devices or slots can result in damage of the HEC module, the amplifier, the head unit / car radio or other connected devices!

Read in the following the steps how to install a HEC module:

1. First disconnect all cables from the device.
2. Remove the bottom plate by loosening the 10 Allen screws.
3. Then dismantle the side panel where the Line Inputs are located by removing the two Allen screws and the three Phillips screws.
4. Prepare the module for installing it into the de-vice. Any further mounting information will be found in the instruction manual of the respective HEC module.
5. Insert the HEC module into the specific slot of the device which is marked in the following picture.
6. Make sure that the HEC module is installed properly and all pins are fully inserted into the socket.
7. Fix the new side panel which is delivered with the Extension Card using the Allen screws and the Phillips screws. Then mount the base plate again.
8. Bolt the HEC module to the side panel. Precise mounting information will be found in the instruction manual of the respective HEC module.
9. Reconnect all cables to the device.
10. Turn on the amplifier. The HEC module is automatically detected by the device and the Status LED of the HEC module lights up green.
11. Now you are able to configure the HEC module in the DSP PC-Tool software.
