DSP PC-Tool Version 3

Here you can find the latest version of the DSP PC-Tool V3

The DSP PC-Tool Software Version 3 is a completely revised version of the previous Version 2 with several new and enhanced features and is used for easy configuration of Audiotec Fischer DSP products. Despite its increased functionality, this software is just as intuitive and easy to use as its predecessor. During development, we made a point of not changing the well-known and much praised Look & Feel that was first created. Anyone familiar with the previous software will be able to find their way around and take advantage of the benefits brought in Version 3. Thanks to the integrated demo Mode, users are allowed to extensively test the software without a connected DSP or amplifier with integrated DSP.

Quick Tips and ATF Sound Tuning Magazine

Quick Tip - Main Menu

In the main menu, various sections such as the channel selection, crossovers, time correction and the equalizer are displayed at the same time and thus provide an overview of the current settings. 
The following graphic gives you some helpful tips for working in the main menu. Detailed information about the different areas can be found in our Sound Tuning Magazine.

Quick Tip - Channel Routing Menu

The Channel Routing menu is used to organize 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 graphic on the left shows you how easy it is to organize the inputs and outputs with the DSP PC-Tool. More detailed information on channel routing can be found in our Sound Tuning Magazine.
