How DRC works?
Dynamic Room Correction (DRC) utilizes very sophisticated algorithms and processing circuitry to solve this problem. The DRC 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 “dynamic” target curve used to calculate corrected room filters in real time.
For example, if the master level reads –10.3 dB 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 immediately. The same process repeats again for any new master level setting.
