This professional and yet very user-friendly software is used to easily configure Audiotec-Fischer DSP products. The numerous adjustment options leave nothing to be desired and thus guarantees extremely precise sound adaptation, even while under difficult conditions. Thanks to the integrated demo mode, the software can be extensively tested or used create a sound setup profile without a DSP connected.
The user interface
The user interface has numerous display areas, such as the menu bar, the channel selection, crossovers, time correction and the equalizer at the same time, thus providing an overview of the most important settings.
The channel assignment
The Channel Routing menu is used to arrange all input and output channels. Here you can name the channels individually, mix input signals together and assign the input signals to the outputs.
The runtime correction
The IO menu (input - output) is used to arrange all inputs and outputs. Summarising input signals also happens here. Thanks to the intelligent "Distance" mode, the runtime correction becomes a breeze. All you have to do is measure the distance between the speakers and the listening position and enter the values (in cm) in the appropriate input fields. The required delay for the individual channels is then automatically calculated by the program.
The Real-Time Analyzer
A real tool for the real sound designer! The Real-Time Analyzer in combination with a measuring microphone (e.g. our MTK1) makes it possible for the comfortable adjustment of the DSP. For highest measurement precision the functionality has been extended by the implementation of several important features. The resolution can now be increased to the finest 1/24 octave steps in order to capture and measure even the smallest resonance in the vehicle. In addition, the display between bars, lines or point display can be varied as well as the duration of the measurement and the curve smoothing. This will ensure that nothing stands in the way of the perfect setup of our DSP products.

FX menu - A rare issue with the "Augmented Bass Processing" feature has been fixed.
BRAX DSP has been implemented The BRAX DSP has numerous new features and functions which have been added to the menus. Amongst others these are some of the new features:
Input Signal Analyzer - This analyser allows to measure the frequency response of each analog signal input. In addition it is possible to sum two ore more signals in front of the analyser and to change their summing ratio. This allows an much easier summing of active speaker level inputs as well as the detection of equalization and allpass filters on the highlevel inputs. All adjustments of the Input EQ are applied in advance of the signal analyser which allows to verify the adjustments directly with the frequency response chart.
Input EQ - The Input EQ has been changed to a channel separated Input EQ and it is now possible to configure each EQ band as a shelf-, allpass or parametric filter.
BRAX DSP hardware configuration menu - This hardware overview page in the DCM menu shows all installed input and output modules of the BRAX DSP. In addition each module is listed with its device specific measurement values (THD and S/N ratio), serial number and allows to configure the hardware of each module individually.
ACO features - This DCM menu allows to adjust several global hardware-specific configurations.
FX menu - The BRAX DSP offers all new prorietary Audiotec Fischer DSP Algoritmen like the RealCenter, StageXpander, Augmented Bass Processing, ClarityXpander & co. In addition the BRAX DSP features a unique, Brax DSP-only new algorythm called StageEQ which allows to equalize the monaural and stereophonic information of a stereo signal individually. We will publish more about this feature soon.
The maximum time delay per channel has been extended to 30 ms.
HELIX DSP MINI - big update for ACO firmware and DSP operating software The DSP MINI got a big update which enables the compatibility to the DIRECTOR (with firmware 2.00) and new functions have been added like the new Input Signal Analyzer and the channel separated Input EQ (see explanation above). Attention: This update will erase all configurations saved in the DSP. The configuration needs to be reloaded after the update.
General optimizations and bug fixes:
Allpass filters could now be used down to 100 Hz without any limitations of the Q-factor (0.5 - 15)
Time - The mouse wheel can now correctly be used to change the slider for the time delay adjustment
Two buttons beside the graph in the main window have been added (one only for high-res products) which can be used to extend the scale for gain and frequency.
ACO products can now be automatically updated by the DSP PC-Tool. These devices allow an update of the DSP operating software and CoProcessor architekture.
several small optimizations & bug fixes
MATCH UP 7DSP has been implemented
Several small optimizations and bug fixes
HELIX DSP MINI has been implemented
The new ACO CoProcessor platform has been implemented. This platform offers several new functions as well as a much faster connection. Thereby the connection between the computer and the DSP, the saving, loading and changing of sound setups as well as the complete update process of the device is getting much easier and faster than before. In addition each DSP which incorporates the new ACO platform is equipped with a new flash memory for storing up to 10 sound setups internally. Those sound setups can now be switched within milliseconds and editied without closing the software. In addition there are several new functions which can be found in the new "ACO Features" tab in the DCM menu.
The FX-Menu, which will be available for all devices which incorporate the new ACO plattform, has been optimized for the universal use of our unique DSP algorythms to configure them more in detail.
The Sound Setup Menu (click on the setup name) has been extended when connecting to an ACO device:
Rename - renames the actuall selected sound setup
Load - loads the selected sound setup
New - creates a new sound setup in the selected sound setup memory with basic flat adjustments
Copy - creates a copy of the actual loaded sound setup in the selected memory
Delete - deletes the selected sound setup
Main - a new function called "Notes" has been implemented which allows to store short comments about the actual sound setup. Those notes will be saved in the sound setup file (afpx) and as well as in the internal memory of the DSP. Therefore the number of characters of this function has been limited to 500 for now. You will find this function by clicking on the note symbol beside the sound setup name.
MATCH UP 7BMW - an issue with the optical input has been fixed. Therefore an update of the DSP operating system will be necessary. Please save your DSP adjustments in advance on your laptop.
Several small optimizations and bug fixes
Fixed a bug in the new backend of software which caused issues with the 56-Bit DSP plattform (MATCH M 5DSP, MATCH PP 62DSP, HELIX DSP) on some computers. We are sorry for the issues and the short update cycle.
MATCH UP 7BMW has been implemented
New main menu button called FX has been implemented to configure the new DSP features of the UP 7BMW amplifier
Augmented Bass Processing Contains the "Dynamic Bass Enhancement" algorythm and the "SubXpander". The Dynamic Bass Enhancement extends and boosts the deep bass response depending on the listening volume and the music signal. The lower the listening volume and/or the low frequency proportion in the music signal is the more our algorythm is working to optimize the bass reproduction. The SubXpander is a separate function which adds subharmonic tones to the fundamental bass for an ultra-deep bass experience.
Center Processing Contains our proprietary "RealCenter" algorythm, which emphasizes the monaural information of the left and right stereo signal and dynamically processes and reproduce a center signal. As a result a unique staging for the driver and passender seat can be achieved at the same time. The ClarityXpander is a separate function which statically or dynamically improves the high ferquency response to create crisp and clear brightness on the center channel.
Front Processing Contains our proprietary "StageXpander" algorythm which enlarges the sound stage provided by the left and right side speakers to achieve a wider stereo panorama. The ClarityXpander is also available on these channels as a static function to create a crisp and clear brightness as well on the side speakers.
IO - A bug in the Input EQ has been fixed which could cause issues when convertig an input EQ band into a shelving filter
Several small optimizations concerning the freely skalable GUI have been done and a new backend has been integrated to support upcoming new DSP plattforms
RTA - Minimum window height has been optimized to have the possibility to place the RTA window above the EQ sction also on small screens
IO - A bug in the Optical Output Routing of the P SIX DSP has been fixed which allows now to route the DSP channels G & H to the optical output of a HEC module
The AutoSet function of the RTA is now muting all non-active, non-linked channels automatically as intended
A bug has been fixed which could cause issues when saving Sound Setups to the DIRECTORS memory
The rename function for the DIRECTOR Sound Setups is now working properly again
Several small optimizations and bug fixes
This updates is only a software update. No DSP plattform will need an forced firmware update.
Extended multi-language support - Finnish has been added to the language selection
DCM - a new menu has been added for the DSP.2, the DSP PRO and the DSP PRO MK2 which allows to deaktivate the output limiter in the DSP signal path. The output limiter is used to protect the output stage against digital clipping (0 dB limiter). If the digital clipping protection is deactivated it is mandatory to make sure that the output level bar will never show up completely red at any listening volumes. If the output level bar lights up red digital clipping is detected which can cause damage to the connected speakers.
The volume control behaviour of the URC remote control has been optimized - this update will only be applied if a factory reset / DSP update is done
A bug has been fixed which could cause a software crash when products with a 15-Band EQ on specific channels were connected
A bug has been fixed which caused an irregular behaviour of the polarity button if specific channel types were selected. The polarity buttons are now working correctly for all channel types.
This updates is only a software update. No DSP plattform will need an forced firmware update.
New configuration menu added to the launcher screen – accessible via the gearwheel symbol
Extended multi-language support – German has been added to the selection, more languages will follow soon
During the update process it is now possible to save the internal configuration files (afpx-files) before the update process is started. This function does also work if the configuration was done with an older software version of the DSP PC-Tool (V3 und V4). Each memory can be saved individually by pressing the “Save afpx 1” and “Save afpx 2” buttons at the Update dialog.
Main – The high- and lowpass filter slope are now showing “off” instead of “0 dB/Oct.” to point out that the filter is deactivated.
Main – The “Self-Define” filter characteristic now shows the correct filter slope of “-12 dB/Oct.”
Main – The frequency graph is now placed again exactly above the 30-band equalizer to have a better visual assignment of the graph frequencies to the EQ-band frequencies. Unfortunately this change limits the frequency graphs maximum frequency to 20 kHz instead of 40 kHz for our high-res audio products. Nevertheless this is only a visual limitation and no technical limitation so the frequency response of the device is not affected and it is still possible to place parametric EQ-bands up to 40 kHz.
DCM – All adjustments done under the „DSP PC-Tool configuration“ tab are now stored globally and have not to be configured for each sound setup individually
DCM – The view and the names of the signal management tab have been optimized and direct links to the corresponding signal routing matrices have been added
IO – A new box has been added which shows the actual signal management configurations for each signal routing matrix at the top right corner. In addition a gearwheel symbol has been added to jump directly to the signal management page
Several Labels have been reworked and renamed
The keyboard shortcut “r” has been added to the Main screen to import a “Room EQ Wizard” specific EQ coefficients file for the selected channel.
If the DSP PC-Tool Version 4.20a is used with upcoming DIRECTOR Update V1.70 the second, device internal memory slot will be deactivated as long as the DIRECTOR is connected to the DSP. This is necessary to fully avoid incompatibilities during the saving and switching process to the second memory slot. As soon as the DIRECTOR is disconnected and the DSPs USB port is used the second memory slot is activated again. This change reduces the total usable memory slot in combination with the DIRECTOR to 21 instead of the primary 22 slots. The second memory slot will be skipped automatically in the upcoming DIRECTOR Update V1.70.
Several small bugs have been eliminated, i.a. issues at the AKM DAC configuration for the DSP PRO MK2, time alignment adjustment errors for the HELIX DSP, signal management issues for the PP 62DSP, crashes while load a sound setup, window scaling issues at low screen resolutions, reduced processor loads, etc.
The minimum window height has been fixed to allow a full screen view of the software on screens with a maximum vertical resolution of 768 pixels.
HELIX DSP has been implemented
MATCH PP 62DSP, PP 82DSP und M 5DSP have been implemented
The last used window size will now be saved when closing the software and recalled after opening it again
Main - A new Copy Menu has been implemented. The menu can be opened by right clicking on a non-selected channel in the top channel navigation of the main window. The menu allows to transfer specific data from the selected active channel to the right-clicked channel. The data which should be transferred can be selected in the new menu, data which is not compatible between the channels cannot be selected e.g. phase data between a full range and an active speaker channel due to the different phase adjustment possibilities.
Main - A new "polarity switch" button has been implemented to make the difference between phase adjustment and polarity inversion more clear. The button is available on all channel types and has the same funtion as the former phase adjustment mode where only 0° or 180° was selectable. A polarity inversion affects the whole frequency range and is the same as inverting plus and minus wire at the speaker. The phase adjustment still influences the phase alignment at a specific frequency and is only available in active speaker setups. The option to invert the polarity in the IOs signal summing matrix keeps unaffected.
Main - The middle frequency of the Shelf-EQ kann now also be marked by using the mouse and edited by using keyboard inputs. The same is possible to enter 1 Hz accurate frequencies in the high- and lowpass filter section.
IO - The input signal objects (left box) now shows also the device specific input name which is written beside the physical inputs at the device.
The EQ-bands are now inaccessible during the activation of the Equalizer-Bypass function, to avoid undesired adjustments.
DCM - The "PC-Tool Configuration" tab now shows a new option called "EQ View Mode" which allows to extend the frequency graph by displaying EQ points. By choosing the option "point" the frequency graph just shows all EQ points in the frequency graph. By choosing the "drag & touch" option a mouse or a touchpad can be used to adjust the EQ points directly in the frequency graph. Each EQ point is connected to an EQ-band, the color of the EQ point displays the EQ characteristic (red = para-graphic EQ, blue = parametric EQ, yellow = allpass filter, green = shelf EQ). By selecting an EQ point the corresponding EQ-band is automatically selected and converted into a full parametric band to avoid any limitation in adjustments. The mouse wheel can further be used to change the Q factor. We are also working on proper multi-touch function to change the Q-factor as well by fingers.
Main - New keyboard shortcuts have been implemented. The button "D" can now be used to make the window borderless to maximize the full screen support of the software.
Devices which have a native sampling rate of 96 kHz have now an extended adjustment range of the parametric EQ-band center frequency up to 40.000 Hz to optimize the frequency response also in the higher frequency ranges e.g. to handle resonance frequency peaks of hard dome tweeters
The DIRECTOR will now be automatically selected as the active remote control in the DCM menu if the connection to the DSP is established via the DIRECTORs USB port.
HELIX P SIX DSP MK1 has been implemented

HELIX V EIGHT DSP - fixed an issue in the Analog Input Delay
HELIX DSP PRO - fixed an issue in the Analog Input Delay
HELIX DSP PRO MK2 has been implemented
Added support for the following devices: HELIX DSP PRO, P SIX DSP MK2, V EIGHT DSP
Bypass Button (beside EQ) deactivates only the EQ and has no effect on time alignment any more
DCM – Turn On and Off Delay have been added for HELIX DSP.2 and DSP PRO MK2
Graph window has been optimized due to the scalability
HELIX DSP PRO MK2 – Asahi Kasei Microdevices Sound Filter Options of the DA converter are now adjustable
Several minor improvements of the usability and scalability
Please note: The support of further products will be added gradually. Each device has to be implemented and tested separately. As soon as all 64 Bit DSP devices have been implemented we will start to integrate the 56 Bit DSP platform as well.
