Dynamic Room Correction (DRC) ® is new technology developed by Tact Audio Inc. over past two years. This groundbreaking brings the science and art of Room Correction, and specifically Tact room correction products, to yet another level.

How does it work?

Dynamic Room Correction (DRC) offers a very sophisticated way of handling a multi target curve approach to solving equal loudness curve problem. The system is based on one reference target curve and eight additional target curves called dynamic target curves. The reference target curve is used to perform basic reference room correction. Dynamic target curves are labeled 0, -6, -12, -18, -24, -30, -36 and –42 dB and are combined with the reference target curve to obtain the final target curve used to calculate correction filters. For example, if the master level reads –10.3 dB (89.6 on the relative readout) the system will use the –6 dB and the –12 dB dynamic target curves and by interpolation will calculate a target curve corresponding to –10.3 dB. After that the system will combine the 10.3 dB target curve with the reference curve to obtain the final target curve that is then used to calculate the correction filters. New correction filters are loaded into the signal path as the music is playing and the new correction takes effect in a split of a second. The same process repeats again for any new master level setting. What is the purpose of the computer interface? With a DRC system, a computer is used only as a graphical user interface (GUI) and serves no other purpose. All calculations are performed inside the DRC processor. Target curves, measurements and other correction parameters are filed inside DRC flash memory. This approach will allow us to offer other GUI devices besides window based personal computers. After target curve modification is made how long does it take for the new correction to be engaged? Another main advantage of DRC technology is the elimination of the correction filters calculation and programming step. If you are current Tact user you are aware that, after the room measurement was completed and target curve was selected, you had to go through relatively long process of programming your RCS device with correction filters before being able to listen to the new correction. With the DRC technology when you make a change to the target curve, or select a new one, you click on the GUI ‘Calculate’ button to instantly calculate and engage new correction filters. This new feature allows you to make small adjustment while you are listening to your favorite track and instantly here the changes you made. In this way without any interruption to the music you can make your system sound perfect down to the smallest details.

Tact Audio is constantly pushing the limits of technology to bring you the most life like at-home music experiences. As a result of this effort Tact Audio has pioneered a number of ground braking room correction and digital amplifier innovations.

Tact Audio, Alex

All Tact room correction products support user defined target curves. Target curves can be modified in real time without any interruption to audio signal. Tact-2.2 XP, Tact-2.2 MINI and Tact-2150 XDM support standard room correction with one target curve as well as Dynamic Room Correction (DRC) with eight additional target curves. Dynamic target curves perform equal loudness compensation that is linked to master level control.
