TECHNOLOGY
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.
Acoustical Design
only requirement for exceptional engineers understand that the room in
which the loudspeaker is placed can greatly affect its performance.To ensure that Intermezzo Series loudspeakers will sound exceptional in even the most unexceptional listening environment, Infinity has developed two ways to solve most roomgenerated problems.The first is its proprietary Room Adaptive Bass Optimization System™. With a single band of parametric equalization, the Intermezzo 2.6 can be adjusted to tame any problematic room bass resonances below 80Hz.
There is a completely different set of room-related problems that has to do with loudspeaker directivity and that can affect the reproduction of mid and high frequencies. One characteristic of forward-facing loudspeakers is that the sound output lessens as one moves away from the principal axis.This happens both horizontally and vertically and it means that radiated sounds that are reflected from the floor, ceiling and side walls will be lower in amplitude than direct, forward sound.This is usually a good thing. But, if the dispersion characteristics of the loudspeaker are different at various frequencies, the sound quality of the reflected sounds will be very different both from each other and from the first (i.e., direct) sound.The ears don’t ignore these differences; they perceive them as coloration, or as sound quality that’s been degraded. Intermezzo loudspeakers have been carefully designed to maintain a directional pattern that is similar at every important angle, on and off axis.The positive result is that both direct and reflected sounds arriving at the listeners’ ears have similar timbral signatures.
Completing the Experience
The technology and performance that make Infinity Intermezzo loudspeakers ideal for music listening also make them the perfect digital multichannel loudspeaker system.To complete a home-theater system, Infinity has designed, to the same precise standards as for Intermezzo 2.6, a matching 3-way center-channel loudspeaker and a 12," 850-watt powered subwoofer.
We hope you enjoyed this brief introduction to the technology of Intermezzo loudspeakers. If you would like to further explore their technology and design, please ask your Infinity dealer for the C.M.M.D. and R.A.B.O.S. White Papers.The White Papers can also be downloaded from Infinity’s Web site at www.infinitysystems.com.

When set to“On,”this control limits the low frequencies that the Intermezzo 2.6 will reproduce and allows you to use your processor’s/receiver’s bass-management settings for an ideal blend with a subwoofer.
When set to“Off,”the Intermezzo 2.6 will reproduce the entire frequency range. Use this setting only if your system does not include a subwoofer.

This control optimizes the performance of the Intermezzo 2.6 based on whether it is placed on a speaker stand or on a shelf.
If you place the Intermezzo 2.6 on a shelf or inside a wall unit/entertainment center, set this control to“Shelf.”
If you place the Intermezzo 2.6 on a floor stand, set the control to“Stand.”

ROOM ADAPTIVE BASS OPTIMIZATION SYSTEM™
Infinity R.A.B.O.S. is a simple-to-use, yet sophisticated, lowfrequency calibration system. It is designed to work in conjunction with Infinity Intermezzo self-amplified woofers. Each woofer contains a parametric equalizer that you will adjust as indicated by the R.A.B.O.S. test results. Following these instructions, you will optimize the loudspeakers’ response characteristics to complement their environment.This will dramatically improve the sound of your system.The optimization process takes less than 30 minutes.
The R.A.B.O.S. Kit Includes
the Following Components:
•Specialized Sound-Level Meter
•Test CD
•Instructions
•Measurement Templates
•Width Selector
•Adjustment“Key”
What R.A.B.O.S. Does
The Test CD provides specially designed signals you will use while performing measurements.The sound-level meter provided is used to“acquire”the information needed for adjustments.You will create a response plot on the Measurement Template. Using the Width Selector, you will then determine the appropriate equalizer settings.The“Key”is used to adjust the parametric equalizer built into each Intermezzo woofer. After adjustment, the test sequence is repeated to confirm your settings.
The R.A.B.O.S. Goal
It is a fact of audio that what we hear at low frequencies is determined as much or more by the listening room than by the loudspeaker itself. Placement of the loudspeakers and listeners and the acoustical characteristics of the room surfaces are all important determinants of bass quantity and quality. In most practical situations, there is little that can be done about this, except for patient trial-and-error repositioning of the loudspeakers and listeners. Usually, the practical constraints of a living space and the impracticality of massive acoustical treatment mean that equalization is the only practical solution.
Professional sound engineers routinely employ sophisticated measurement systems and equalizers to optimize speakers to the installation.This has never before been practical for the home audiophile.That’s why R.A.B.O.S. was created. R.A.B.O.S. enables you to identify the dominant low-frequency response characteristic of your room. Once you know the problem, R.A.B.O.S. provides the tools needed to optimize the low-frequency characteristics of the speakers to the room they are in, exactly as the professional sound engineers do it.
Performing R.A.B.O.S.Tests
These instructions assume you have already installed your speakers according to the information provided in the Owner’s Guide. It is also assumed that all equipment in your entertainment system is interconnected properly and is in good operating condition.
Preparations
Before beginning R.A.B.O.S. tests, please check the following:
•Make sure all three R.A.B.O.S. controls on the Intermezzo 2.6 are turned fully clockwise.
•Make sure the loudness contour (if any) on your receiver/ processor/preamp is turned off.
•Set the tone controls (Bass and Treble) to their center or flat positions.
•Bypass all surround and effects features of your receiver/ processor/preamp or set to Stereo Bypass.
•If you are using a multichannel surround processor or receiver, make sure all bass-management features are properly set.The Audio channels should all be set to“Small”or“High-Pass”and the woofer set to“On.”
You must have a CD player in the system. A CD player remote control is quite convenient but not essential.
For best results, it is recommended that all major furnishings are in place and that all doors and windows in the listening area are in their normal positions.That is, if you normally listen to music with all doors closed, then this is how they should be during this procedure.
Try to minimize ambient noise while running tests.Turn off all major appliances and any air conditioning or furnace fans.These can create significant subsonic noise that may be barely perceptible but which can wreak havoc on low-frequency measurements.
