The Room Mode Correctionâ„¢System
What Is RMC?
Developed by JBL Professional, RMCâ„¢ is a system designed to calibrate and correct low frequency (LF)
response in typical listening rooms and production facilities. The LSR6328P full range monitor and
LSR6312SP Subwoofer contain a single section parametric equalizer that can be adjusted to compensate
for the major low frequency response peak caused by standing waves in a particular listening space. The
LSR6332, LSR25P and other systems can experience the benefits of RMC when an LSR6312SP is used in
the system.
The RMC process allows you to optimize the low frequency response of your system in your work
environment. Using the tools provided in the RMC Kit, simply follow the instructions step-by-step and
allow approximately 30 minutes to perform the adjustment process for a stereo system. You will
experience a noticeable improvement in the sound quality of your system.
What are Room Modes? Room modes are low frequency resonances caused by standing waves involving
the geometry of the room and its boundary surfaces. The most prominent modes are the ones that occur
between opposite surfaces. If response peaks due to these modes are not corrected, your mixes may be
bass-shy, because you will tend to overcompensate for what may sound like too much bass in the
program. Response peaks due to room modes can be accurately removed by introducing a carefully
tailored inverse response, which RMC provides. You may also encounter response dips, which are due to
local reflections and interferences between the loudspeaker and listening position. The most common
reflections are from the floor. You should be aware that no system of equalization can correct for a
response dip. Dips can only be compensated for by repositioning loudspeakers and/or listeners in the
playback environment. Figure 1 illustrates the typical situation as it exists in most production rooms. The
measured response a the listener is shown in the right portion of the figure. In most rooms, the responset
rise due to the dominant mode will usually be in the range from about 40 Hz to 60 Hz, and the response
dips due to floor reflections will be seen in the range from 50 Hz to about 90 Hz.
RMC provides a method for equalizing the peak shown in Figure 1, but the dip, if it is severe, must be cor-
rected through rearrangement of loudspeaker and listening positions. In most cases however, "floor
bounces" are not problematic.
