Exceptional Design Features
e Sigma 2200i Stereo Integrated Amplier is designed for music lovers and
AV enthusiasts who want high performance control and amplication from a
diverse range audio sources. Its connectivity and processing power accommodate
the ever increasing array of music and AV sources, allowing them to be accessed
and enjoyed without compromise.
versatile connectivity e Sigma 2200i features a comprehensive set of digital and analog inputs
(including optional phono), to support the wide array of connections required
for contemporary audio and AV sources. A line level subwoofer output adds
additional versatility for optimizing system performance.
superior performance Advanced circuit topologies, component parts, and circuit layout techniques
combine for superior audio performance. e analog and digital signal paths
have been optimized to ensure superior performance from every source.
clean, dedicated power A Classé-designed switch mode power supply employing PFC (Power
Factor Correction) provides the clean, high-current power required for best
performance. With PFC, the Sigma 2200i operates at maximum eciency
without disturbing other audio components sharing the same AC mains.
room equalization
and speaker control All home audio systems are aected by room characteristics. Sound reections
and sound absorption can create dramatic variations in the performance of your
system, particularly in the lower frequencies. e Sigma 2200i features a system
of lters which, in the hands of an experienced acoustician, can help optimize
the performance of your system.
flexible GUI efrontpanel’sLCDtouchscreensupportsanextremelyexibleand
versatile graphical user interface (GUI) while maintaining a clean, uncluttered
appearance. e Sigma 2200i provides a range of controls that might otherwise
require dozens of buttons and knobs on the front panel. Despite this power and
exibility, it remains simple to operate in day-to-day use.

extraordinary longevity Because Classé has developed highly rened circuits over many years, we have
vast experience in what works well over the long term. Using this knowledge
base, along with quantitative results derived from highly accelerated life testing
(H.A.L.T.),allowsustoselectonlythemostreliableparts.isattentionto
detail and design allows us to manufacture products which stand the ultimate
test: time.
Just as past Classé products have done for their owners, we are certain that your
new integrated amplier will give you many years of continuous enjoyment.

Unpacking and Placement
We have taken all precautions, and made every eort to make the Sigma 2200i
simple and straightforward to install and use. Still, we recommend that you
take a few minutes to review this manual. Even if you are having the integrated
amplier professionally installed, you will want to know how to eciently
operate it to its potential.
e Sigma 2200i menu system includes features that provide you with a great
deal of ne-tuning. Still, we have no way to evaluate outside variables such as the
acoustical characteristics of your listening space and the associated equipment of
your audio system. erefore, it is up to you to make the nal audio adjustments
for the optimum performance of your system.
For this reason, we strongly encourage you to have your integrated
amplier installed and calibrated by your dealer. e experience,
training, and specialized equipment they have can make a profound
dierence in the nal performance of your system.
unpacking your
Sigma 2200i
Carefully unpack the Sigma 2200i according to the supplied instruction sheet.
Do not forget to remove all accessories from the carton.
Important! Keep all packing materials. Transporting the Sigma 2200i
without using the packaging specifically designed for it may
result in damage that is not covered under the warranty.
Sigma 2200i placement
considerations Before installing your Sigma 2200i, be sure to read the following placement
suggestions.
• DonotplacetheSigma2200idirectlyonthetopsurfaceofa
conventional power amplier or any other heat source. Also keep the
unit out of direct sunlight.
• PlacetheSigma2200isothattheIRwindowonthefrontpanelis
clearly visible and not blocked.
• Position the Sigma 2200i in a central and convenient location for
both visibility and use. e integrated amplier is the hub for all other
component connections and generally your primary interaction point.
In addition, by placing the unit close to the other system components,
you minimize the cable lengths and hence reduce the amount of noise
that is introduced into the system through the cabling.
• Leave adequate clearance behind the Sigma 2200i for the AC cord and
connecting cables. We suggest six inches (15 cm) of free space to allow
cables sucient room to bend without crimping or undue strain .
• Donotobstructtheareaaroundtheunitsothatexcessheatcan
dissipate through normal air circulation.

Important! Obey all placement considerations. Not obeying the
placement considerations may result in damage that is not
covered under the warranty.
warm-up/break-in period Your new Classé integrated amp delivers outstanding performance immediately.
However, you can expect to hear subtle improvements as it reaches normal
operating temperatures and breaks-in.
In our experience, you can expect the greatest changes within the rst 72 hours.
Afterinitialbreak-in,you’llenjoyconsistentperformancelevelsforyearsto
come.
operating voltage e operating voltage of your Sigma 2200i is 100-240 V, 50/60 Hz.
Important! Attempting to operate your Sigma 2200i from an incorrect AC
voltage rating may cause irreparable damage which may not
be covered by your warranty.
If you are not planning to use the integrated amplier for an extended period of
time, for example due to vacation or other travel, we suggest that you disconnect
it from AC power.
Make certain that the Sigma 2200i is in Standby prior to disconnecting it.
Physically disconnect any and all valuable electronics from AC power during
electrical storms. A lightning strike anywhere near your home can generate a
tremendous surge on the AC mains that can jump across a power switch. A surge
from a lightning strike, which may be many thousands of volts, can cause serious
damage to any piece of electronics, no matter how well designed and protected.

Rack-Mounting the
Sigma 2200i
e Sigma 2200i is designed to accommodate rack-mount installation.
Professional installation by an authorized Classe dealer is recommended.
Torackmountthe2200i,removethetwoside-panelscrews,rotateandipthe
side panel to position the rack “ear” along the front of the 2200i and re-install
the side-panel screws. Repeat for the side panel on the opposite side. Remove the
feet from the bottom of the 2200i.
Carefully install the Integrated Amplier into the equipment rack using the
appropriate screws for the type of rack. It is easiest if two people perform the
installation to avoid the possibility of dropping the unit or otherwise causing
damage. Please allow for adequate ventilation, usually two rack spaces above the
unit will suce.
Magnetically secured rack ear covers, provided in the accessory pack, may be
used to cover the screws and nish o the appearance.
