The LSR4300 Series combines stunning sound and legendary JBL design with innovative new
technologies. The end result is a product that is nothing short of revolutionary – a monitoring
system suitable for use in the most demanding music, broadcast, and postproduction
applications.
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.
