1100-LFC CARDIOID ARRAYS
The 1100-LFC low-frequency control element is defined by its sonic linearity in reproducing low-frequency transients at high,
continuous output levels with very low distortion. This ultra low distortion, coupled with exceptional headroom and optimized
rigging options, makes the 1100-LFC ideal for low-frequency directional applications for large-scale tours and installations.
The 1100-LFC can be configured in cardioid arrays to reduce output heard behind the loudspeakers. The loudspeaker’s lin-
earity ensures that cardioid patterns behave accurately even at very high levels. Cardioid arrays are achieved by placing three
units coplanar to each other (in either a groundstacked or flown array) with one unit facing the opposite direction. The output
of the reversed loudspeaker cancels the output of the other loudspeakers normally present behind the units, while also
increasing SPL directed forward.
NOTE: 1100-LFCs need not be equipped with the MRF-1100 rigging kit for groundstacked cardioid configura-
tions.
NOTE: 1100-LFC cardioid arrays can also be flown with the MTG-1100 top grid. For more information, see
Chapter 4, “MTG-1100 Top Grid.”
NOTE: To achieve an accurate cardioid pattern, MAPP Online Pro and the Galileo® loudspeaker management
system are required. Use MAPP Online Pro® to calculate the appropriate ratio of forward to rear facing loud-
speakers, as well as the required Galileo parameter settings for polarity, delay, and gain. An infinite number of cardioid
and directional configurations are possible and can be calculated and predicted with MAPP Online Pro. For more infor-
mation, contact Meyer Sound Technical Support.
