Multi-band DRC blocks
The MERUS™ audio amplifier configurator features two- and three-band dynamic range compressors (DRCs).
These can help music sound louder and more controlled, especially for smaller speaker systems and/or loud
environments. The multi-band DRCs can be used in conjunction with the output limiters to shape the sound of
the speaker system. The output limiters are most useful to keep IC temperature and speaker power in check.
Once these safety mechanisms are in place, the DRCs can then be tuned in any way without the worry of
exceeding these limits.
