les, among others:

• 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 amplier’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-specic setups” in the PP50 DSP user manual.

Information on the P-DSP:

The P-DSP is supplied as standard with operating software for conguring 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.

CONTROL INPUT

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 specic

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 amplier

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 amplier

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 congu-

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 specied 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 amplier/processor must be connected to the computer and all the specic 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 conrmation, 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 amplier. Please use the “Store

DSP” button for this.

It is not possible to install the .afp les directly in the amplier/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 amplier’s/processor’s internal memory. The amplier then accesses this setup in its memory

each time it is switched on. The .afp le is also always saved in the amplier/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.
