• Now double-click on the “USB driver.exe” le to install the USB communication driver. This
driver must be installed before you start the “HELIX DSP PC-Tool Rev X.xx.exe” program!The
following window will appear on your PC when you install the USB driver:
Important information:
If this window does not open, please execute the “USB driver.exe” le again.
Installing the driver itself can take up to 1 minute, depending on the PC.
• Once the driver has been installed, your PC is ready to use the software.
• You may now connect the processor and/or USB interface to a free USB port on your PC.
Information on the PP50 DSP:
The PP50 DSP is supplied as standard with operating software (.af1-le) for adjusting the DSP via
the PC-Tool. This le is located in the amplier’s rst memory bank (af1). If communication prob-
lems occur between the PP50 DSP and the interface/PC-Tool, please install the most recent ver-
sion of this le. The le can be found under “Download” under the PC-Tool tab on our homepage.
Download the latest version of this le and install the le via a micro SD card. Detailed instructions
can be found under “Installing vehicle-specic setups” in the PP50 DSP user manual.
Information on the P-DSP:
The P-DSP is supplied as standard with operating software for conguring the DSP via the PC-
Tool. If communication problems occur between the DSP and the computer, please install the most
recent version of this le. The most recent le can be found under Download under the PC-Tool
tab on our homepage. Detailed instructions on updating the operating software can be found in the
P-DSP user manual under “Updating the operating software”.

Connecting the PP50 DSP to the PC
• Connect the red connector of the HELIX Optical & USB Interface to the red “CONTROL IN-
PUT” on the PP50 DSP:
• Connect the HELIX Optical & USB Interface USB connector to a free USB port on your PC.
• Switch on the PP50 DSP via your car radio.
Please note: The interface connector may only be inserted one way
up. Do not attempt to force the connector into the “CONTROL IN-
PUT” the wrong way up.

Connecting the C-DSP/P-DSP to the PC
• Connect the P-DSP directly to the computer using the supplied USB cable.Use the USB port
on the P-DSP.
• Then insert the USB cable into a free port on the computer.
• Now switch on the P-DSP via the radio or the remote input, or via the high level input.
Please note: It is not possible to use the HELIX USB Interface with this
processor. Only use the P-DSP USB port to connect to the computer.

Starting the software
Requirements:
• The software and the USB driver have been installed correctly
• The PP50 DSP or the C-DSP/P-DSP have been connected correctly to the computer
• The most recent version of the operating software has been installed on the PP50 DSP and/or
the C-DSP/P-DSP: instructions can be found in the user manual of the respective device
In order to start the software, please execute the HELIX DSP PC-Tool Rev 1-XX.exe le.
The following window will then appear on your screen:
Now press the “Connect” button. If the PP50 DSP or the C-DSP/P-DSP has been connected cor-
rectly, the program user interface will appear within 5-15 seconds:

The following window will appear if the PP50 DSP or P-DSP is not connected correctly or the USB
drive is not installed correctly.
You can still start the software in demo mode. However, it is not possible to make any adjustments
in demo mode as the device is not connected.
If you start in demo mode, you then have the option of selecting the user interface for the specic
device. The user interface will open automatically on selection.
Important information about the PP50 DSP:
• If you start the software in demo mode, it will not recognize any optical and USB interface sub-
sequently connected. It is then necessary to close the program completely and restart it.
• Once the PP50 DSP has been connected to the PC via the HELIX USB Interface, the amplier
will be in PC mode, which deactivates various functions such as the under voltage detector or
the automatic switching on/off using High Level or Remote, for example. This status remains
active until you close the software again correctly using the “Close” button. It is not enough to
simply break the connection between the PC and the PP50 DSP. If you do this, the amplier
remains in DSP mode for up to an hour and does not switch off, even if you switch off your car
radio!
Important information on the P-DSP
• Once the P-DSP has been connected to the computer and the PC-Tool started, the P-DSP will
be in PC mode. However, it does not remain switched on if the remote input signal or high level
signal is switched off. Please ensure that these signals remain switched on during the congu-
ration process.

Reset button:
The Reset button is used to reset all the adjustments made in the software. Pressing this button
also resynchronizes the connection between the device and the software.
Important information:
If you accidentally press the Reset button while adjusting the DSP without having saved your se-
tup, you will loose all your data.
Save button:
Use the Save button to save an adjusted setup to a specied location on your PC. Clicking on
the Save button opens a window which allows you to select the location and give the setup a le
name. All setups are automatically given the le extension .afp. The .afp les contain all the PC-
Tool software settings and may only be opened using this software.
The Save button is also used to save the DSP settings as a micro SD card le. To use this func-
tion, the amplier/processor must be connected to the computer and all the specic settings al-
ready adjusted (the settings must be saved using the “Store DSP” button). Then right-click on the
Save button. A window will now open which allows you to select the location. On conrmation, the
program generates a micro SD card le with the le extension .ac1. This process can take up to a
minute!
This le can then be simply installed via the micro SD card slot on any of the devices of the same
type without the need for the device to be connected to the computer.
Please note: It is then no longer possible to open, and therefore amend, the .ac1 le. We therefore
strongly recommend saving the settings as .afp les.
Important information:
Saving the settings as an .afp le does not save them in the actual amplier. Please use the “Store
DSP” button for this.
It is not possible to install the .afp les directly in the amplier/processor via the micro SD card
slot, the PC-Tool must be used instead.
Store DSP button:
The Store DSP button is used to permanently transfer the settings you made in the PC software to
the amplier’s/processor’s internal memory. The amplier then accesses this setup in its memory
each time it is switched on. The .afp le is also always saved in the amplier/processor and loaded
from the device when the software opens. Nevertheless, we still recommend that you also always
manually save the .afp le on your computer.
