Tact-2.2 XP can now perform room correction automatically from the 2.2 XP front panel user interface, without the need for an PC software.

The automatic room correction feature is designed to perform the entire room correction process without using a PC interface. The Tact-2.2 XP has sufficient DSP processing power to perform room measurement, crossover filter design, target curve generation and correction filter calculation. The entire process is controlled from the 2.2 XP front panel DRC-RCS menu. Target curve and crossover filter adjustments can be made on the fly while the music is playing. Users can, for example, specify a boost at low frequencies or a roll-off at high frequencies. Values of the ‘low’ and ‘high’ frequencies can also be adjusted.

PC based room correction requires that the 2.2 XP is connected to the RS232 port of a PC. PC software is used just as a GUI (graphical user interface) to provide the user with a graphical presentation of the correction process. After the room response measurement is completed, the room frequency response for all measured channels can be displayed on the screen. Crossover filters and actual correction filters can be viewed. The displayed graphs provide valuable information that helps users design their own optimum target curve.

The Tact-2.2 XP memorizes two sets of target curves: computer generated and automatically generated target curves. When the automatic feature is turned OFF, the 2.2 XP will use a computer generated set of target curves. When the automatic feature is turned ON, the 2.2 XP uses target curves generated by the 2.2 XP front panel automatic correction feature.

When the 2.2 XP is connected to a PC and the automatic feature is enabled, automatically generated target curves will be uploaded into the RCS/DRC screen. The curves can than be saved or modified. Modified curves can than be loaded back into the 2.2 XP. However, the uploaded curves will not take effect until the automatic feature is disabled. Any target curve uploaded to 2.2 XP is saved as a PC generated target curve and takes effect only when the automatic feature is disabled. In another words, if a target curve is to be modified by the PC software, the automatic correction feature has to be disabled.
