NTRODUCTION
The Infinity Modulus Home-Theater System is a compact,
efficient, universal satellite, center-channel and subwoofer
system that is ideal for reproducing home-theater sound. With
their versatile design, the satellite speakers can be placed
virtually anywhere on shelves or stands, or mounted on a wall or
ceiling using the supplied base.The center channel can easily be
placed on top of, or on a shelf below, the television.The powered
subwoofer delivers tremendous bass performance from a
compact, easy-to-place design.
About This Manual
To start enjoying your new Modulus Home-Theater System, read
and then follow all instructions listed in this guide, as well as
those found in the owner's manuals of associated components in
your audio system. Save all instructions for future reference.

ECHNOLOGY
Modulus loudspeakers incorporate several innovative technologies
that, when implemented by our exceptionally talented engineers after
hours upon hours of subjective listening evaluations, result in a
loudspeaker that realistically and accurately reproduces the signal
source with minimal distortion and coloration.
Ceramic Metal Matrix Diaphragms
For decades, loudspeaker engineers have known that the ideal
transducer should be stiff, yet light, and have high internal
damping (damping is a material's ability to absorb energy).
Infinity's C.M.M.D. transducer is a significant advance in
transducer technology. Ceramic, a class of material new to
loudspeakers, offers better performance than other materials.
Ceramic is stiffer than metals and lighter than plastics and
typical composite materials; it also offers improved damping.
These ceramic-based transducers take us a giant step closer
to the ever-elusive "ideal transducer."
In tweeters, C.M.M.D. technology offers stiffness and damping
superior to that of traditional metals and soft-dome materials.
In woofer and midrange applications, it offers accurate pistonic
operation over the entire frequency range of the driver,
completely eliminating coloration due to cone breakup and
dramatically reducing distortion. And when ceramic-metal-matrix
transducers are exposed to moisture, sunlight or extreme
temperatures, their performance does not deteriorate.
In addition to ceramic diaphragms, all the transducers incorporate
magnetic shielding and rigid cast-frames that, through our FEA
computer modeling and scanning-laser-vibrometer measurements,
have been optimized to reduce resonances.This ensures minimal
distortion and incomparable performance.

Amplifier

BASH ® is an amplifier-power-supply technology that increases
efficiency by reducing power dissipation in the output section.
The BASH topology uses a high-efficiency, fast-response, switch-
mode power supply that provides the main voltage rails for a
linear Class-AB amplifier. By varying the output of the power
supply with the audio signal being amplified, a constant voltage
drop across the output transistors of the linear amplifier can be
maintained.This means that the power dissipation in the output
transistors is greatly reduced.
The result is an extremely efficient audio amplifier that does not
compromise audio performance.

Room-Friendly Acoustical Design

Driver quality is not the only requirement for exceptional
performance. Infinity's engineers understand that the room in
which the loudspeaker is placed can greatly affect its
performance.To ensure that Modulus loudspeakers will sound
exceptional in even the most unexceptional listening environment,
Infinity has developed the proprietary Room Adaptive Bass
Optimization System™ (R.A.B.O.S.). With a single band of
parametric equalization, the Modulus subwoofer can be adjusted
to tame any problematic room-bass resonances below 80Hz.
We hope you enjoyed this brief introduction to the technology
featured in the Modulus Home-Theater System. If you would like
to further explore Modulus' technology and design, please ask
your Infinity dealer for the C.M.M.D. and R.A.B.O.S. White Papers.
