The biggest design departure in the RCS 2.2 XP from the 2.2 X is that all system processing is done internally and not in an attached PC. The upgrade entails a new motherboard and DSP engine. In previous room correction amplifiers, all calculations were done in a PC that then fed the data to the RCS unit. In the upgraded design, the PC serves simply as a graphical interface. The new motherboard and DSP engine allow for Dynamic Room Correction and on-the-fly adjustment capabilities.

On-The-Fly Adjustments. Having all the processing happen internally means that adjustments can be made instantaneously - you no longer have to wait for the computer to feed data to your RCS unit. If you are a current Tact user you are aware that after the room measurement is completed and a target curve selected, you must go through a few steps to program your RCS device with appropriate correction filters before being able to fully employ the new correction. This new automation allows you to make small adjustments while you are listening to your favorite tracks and to instantly hear the changes you make. In this way you can tune your system’s sound down to the smallest level of detail effortlessly.

Dynamic Room Correction. Tact DRC systems are the only ones in the world to address the issue that sound perception is both frequency and level dependent (Fletcher-Munson Curves). To achieve this, the RCS 2.2 XP uses the traditional Tact reference target curve in conjunction with 8 "dynamic target curves". These additional curves tell the system how you perceive sound at different levels. By incorporating your relative loudness perception, or equal loudness curves, the new RCS 2.2 XP recalibrates your entire system every time you make a change of 0.1 dB. The RCS 2.2 XP thus preserves natural tonal balances by dynamically adjusting your entire system in accordance to human hearing characteristics, your hearing characteristics. More

Automatic Room Correction. The automatic room correction feature is designed to perform the full 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. More
