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.

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 p arameters are filed

inside DRC flash memory. This approach will allow us to of fer other GUI devices

besides window based personal computers.

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
