RMC™ Room Mode Correction

The biggest challenge for anyone producing audio is creating a mix that sounds great on all playback systems. If you think of a monitoring system as a kind of “lens” through which you hear sound, the object is to have the lens be crystal-clear and transparent so that it imparts no coloration whatsoever to the signal being played back. However, every loudspeaker system, no matter how well designed, interacts with the room in which it is installed. Lack of correct acoustic treatment (or, worse yet, lack of any treatment at all) can result in anomalies such as resonant frequencies and low-frequency “standing waves” – the aural equivalent to the lens being “smeared.” Trying to create a mix in such an environment can be as frustrating and difficult as trying to paint a masterpiece while blindfolded.

JBL’s exclusive second generation RMC™ Room Mode Correction technology is designed to solve the problem. A powerful onboard computer in each LSR4300 Series monitor automatically analyzes the frequency response of your room and compensates for low frequency inaccuracies in the listening space by precisely inserting filters so that low frequency signals arrive at the mix position with the intended frequency response. In effect, the LSR4300 Series goes “beyond accurate,” allowing you to eliminate the guess-work and create reliable mixes that translate to any environment. Additionally, the RMC system trims the level of each speaker to compensate for differences in placement relative to the mix position, ensuring balanced mixes.
