CHAPTER 1: INTRODUCTION
HOW TO USE THIS MANUAL
Make sure to read these operating instructions in their
entirety before configuring a loudspeaker system with
1100-LFC loudspeakers. In particular, pay close attention to
material related to safety issues.
As you read these operating instructions, you will encounter
the following icons for notes, tips, and cautions:
NOTE: A note identifies an important or useful
piece of information relating to the topic under

1100-LFC LOW-FREQUENCY CONTROL
ELEMENT
The 1100-LFC low-frequency control element is a self-pow-
ered loudspeaker defined by its sonic linearity in reproduc-
ing low-frequency transients at high, continuous output
levels with very low distortion. This ultralow distortion, cou-
pled with exceptional headroom and optimized rigging
options, makes the 1100-LFC a flexible tool for low-end
directional applications for large-scale tours and installa-
tions.
To guarantee optimum performance, 1100-LFC systems
must be designed with Meyer Sound’s MAPP Online Pro
®
acoustical prediction software. The intuitive, cross-platform
application accurately predicts directional patterns, fre-
quency and impulse responses, and maximum peak SPL for
1100-LFC systems, ensuring that systems deliver the
required coverage and SPL.
NOTE: For information on using 1100-LFC with
MAPP Online Pro, contact Meyer Sound Tech-
nical Support at [e-mail]

An optimally tuned, vented cabinet houses the 1100-LFC’s
two linear, high-excursion 18-inch cone drivers. The loud-
speaker’s 28 Hz to 100 Hz operating frequency range com-
plements LEO-M™, MILO
®
, MICA
®
, JM-1P, and other Meyer
Sound loudspeakers, allowing it to integrate seamlessly with
line arrays and curvilinear arrays.
The unit’s power amplifier operates at voltages from 208 to
235 V AC, at 50/60 Hz. TruPower
®
limiting ensures maxi-
mum driver protection, minimizing power compression while
yielding high constant output under high continuous and
peak power conditions. The amplifier, control electronics,
and power supply are contained in a single field-replaceable
module located on the rear of the cabinet.
Meyer Sound’s RMS™ remote monitoring system comes
standard with all 1100-LFCs and provides comprehensive
monitoring of system parameters on a Windows
®
-based
computer. Convenient XLR 5-pin connectors allow the use
of composite cables carrying both RMS and balanced audio
(XLR 3-pin audio connectors are optionally available).
Protective, plastic skids are included on the bottom of the
1100-LFC cabinet that securely align with the cabinet’s top
slots. Units can be stacked normally or reversed for cardioid
configurations.
