DSP PC-Tool Version 5.00

 First Official Beta-Release!

(32 / 64 Bit)

Release date: 25.05.2022









One of the major new things in DSP PC-Tool 5 is our new proprietary TuneEQ function. This integrated automatic tuning mode provides a new way to automatically adjust your virtual or output equalizers. It utilizes a single spatial averaged measurement with at least 1/6 octave resolution to simulate and evaluate the best possible parameter set for your equalizer to achieve a specific frequency response target. The target itself can be freely designed as a Reference Curve.
TuneEQ is an extremely flexible but simple to use function which will use any given number of equalizer bands to perform a frequency response correction by utilizing the full possibilities of parametric equalizer bands. It will use the full function set of the parametric equalizer including the center frequency, Q-factor and gain adjustment.
One of the major design aspects of this function was to make its usability as simple as possible while the complex processes are done automatically in the background.
To use this function a single spatial averaged measurement is necessary per channel or channel group. This measurement can be done with any linear measurement microphone as the TuneEQ function does not have any special hardware requirements.

Wireless DSP tuning via Bluetooth

DSP PC-Tool 5 offers a new connection method which allows the wireless tuning of the DSP through a Bluetooth connection. To use this new connection method, it is necessary to install a BT HD module in the HEC slot of the DSP. To set up the connection the computers Bluetooth interface needs to be paired with the BT HD module. After this you can select the newconnection mode in the specific menu of the application launcher.


Multi-Device Connect

This software update also offers the option to set up several sessions of the DSP PC-Tool software simultaneously. The option allows to tune several connected devices at the same time by launching the software multiple times. As soon as more than one connected device is identified a new menu will appear which allows to select the specific devices independently if USB, Bluetooth or Wifi is used.

In the following you find a full list of all changes which have been made in DSP PC-Tool 5:

  • The DSP PC-Tool 5 is only compatible to ACO devices

  • The DIRECTOR will require a firmware update to version 3.0. After this update the USB port of the DIRECTOR is not supported any more for DSP tuning

  • The WIFI CONTROL will require a firmware update to version 1.09

  • Multi-Device Connect has been implemented. This feature allows to connect to several DSPs simultaneously via USB, Bluetooth or Wifi.



  • New design with improved usability

  • New connection method - Bluetooth (requires a “BT HD” extension card)

  • Demo Extension Card function - This function allows to start the “Demo Mode” with any of our extension cards loaded into the demo session

  • The software version handling has been further optimized

  • Outputs (formerly Main)

  • The size scaling of all elements has been optimized

  • Linked subwoofer channels will not automatically synchronize their time alignment values any more when the polarity or phase slider is used

  • The memory setup menu is now indicated by an additional gear wheel symbol beside the file name section


DCM (Device Configuration)

  • Remote Control – CONDUCTOR
    The CONDUCTOR automatically gets a new firmware update which introduces the “Tone Control” function on the CONDUCTOR. The Tone Control can now be activated in the CONDUCTOR configuration and will then be a new option in the menu structure. When activated the frequency for the low shelf and high shelf filter can be set up in the configuration window. The CONDUCTOR itself will only control the gain of this control (+/- 6 dB). The low shelf filter will be colored in purple, and the high shelf filter will be colored in yellow. While in the Tone Control menu on the CONDUCTOR a long press on the button toggles between both filter options.

  • PC-Tool Configuration
    A new option called “RTA window mode” has been added which allows to change the implementation of the RTA window. The option “windowed” will open the RTA as a separate window. When “embedded” is selected it becomes an integrated function in the “Outputs” screen. The embedded mode can be quite handy on small screens. In this mode the channel selection and the equalizer configuration can be directly accessed.

  • Source Volume Control
    This option has been removed and is now always activated. The adjustment boxes in the IO menu have been relocated to the top right menu in the IO screen.



  • The “Front Processing” tab including its configuration options has been removed. This was necessary to free up some processing power for new features we are working on!
    Due to this “StageXpander”, “ClarityXpander” for the front channels as well as the “StageEQ” will no longer be available in any unit (only when using DSP PC-Tool V4.80 or lower)



  • The source volume control has been repositioned to better visualize that the source volume control is applied to the whole routing matrix (Main, HEC/AUX or Digital) and not to the specific input groups where it was aligned in the software (beside the words “Analog”, “HEC/AUX” and “Digital”). It is now located in the upper right area in the same box which indicates the activation method and adjustment for the selected routing matrix.



  • ATM has been slightly optimized and some minor bugs have been fixed



  • TuneEQ has been implemented as a new automatic tuning mode

  • TuneEQ is a new tuning mode beside “SetEQ” and “AutoSet” and uses a different approach than before. While the first two options were iterative measurement options which you had to perform several times in a row to achieve a great result, TuneEQ is a one-shot approach which achieves a great result just after a single measurement.

  • TuneEQ is using a completely new approach by utilizing a spatial averaged single measurement in a higher resolution of 1/6 octave and performing all the necessary iterations in a highly complex simulation in the background. So instead of doing iterative measurements the TuneEQ algorithm is performing millions of real filter simulations in the background which will be applied to the real measurement data until it finds the best parameter set. This parameter set includes an adjustable number of fully parametric EQ bands, with each band automatically adjusted in frequency, Q-factor and gain. Depending on the preferences TuneEQ can utilize only a few EQ bands or up to 30 bands per channel to maximize the possible result.

  • The TuneEQ function still works with any measurement microphone and does not require any new hardware. It is also designed extremely versatile so that it is available from the beginning in all available and upcoming ACO devices.

  • TuneEQ only involves a very few adjustment options:

    • The maximum targeted deviation (default 0.1 dB) can be configured

    • The maximum overall boost (default + 6 dB) can be configured

    • You can configure how many EQ bands of a specific channel should be used by the TuneEQ mode (default is band no. 3 to band no. 29 as the low- and high shelf filters are allocated to the first and last band of each equalizer and the Tone Control functions of the remote controls allocate band no. 2 when activated)

    • You can adjust the frequency range where the TuneEQ should be utilized

  • Another two new options in the RTA settings are the following:

    • RTA graph settings - “Adjust Frequency limits to selected channel Filters”.
      This option will automatically set the frequency range selection for the automatic tuning modes based on the adjusted high- and low pass filter of the selected channel i.e. If you have a band-passed midrange driver with a highpass filter of 300 Hz and a lowpass filter of 5 kHz, the frequency range will automatically be set to be within this range. No manual adjustments are necessary.
      Reference Curve Settings - "Adapt refence Curve to selected channel filters".
      This option will automatically calculate the adjusted high- and low pass filter of a selected channel into the reference curve. This option allows to utilize equalizer bands in combination with the TuneEQ function to shape the acoustical slopes of the adjusted high- and low pass filters.

    • The frequency range adjustments for the automatic tuning modes allow now to directly enter your own frequency values on a 1 Hz precision (instead of the 1/3 octave selection from the drop-down menu)
