Welcome to the Classé family
Congratulations on your purchase of a Classé product. It is the result of many
years of continuous refinement, and we are sure that you will enjoy it for many
years to come.
We value our relationship with our customers. Please allow us to stay in touch
with you by returning your warranty card now, before you pack up the shipping
carton of your new product and forget all about it. Doing so will enable us to
let you know about any possible future upgrades or updates that might become
available for your Classé component.
Sending in your warranty card also registers your product with us so that
warranty service can be obtained easily and quickly, even if you have mislaid
your original sales slip.
Please, take a few minutes to fill out the warranty
registration card, and drop it in the mail.
You will find the warranty registration card at the end of the separate warranty
policy booklet, enclosed.
a word about installation Every effort has been made to make the Classé CAP-2100 simple and
straightforward to install and use.
Still, we have no way to evaluate many other variables such as the size and shape
of your room, its acoustics, and the associated equipment you have chosen to use
with your amplifier. All of these factors influence the ultimate performance of
your system.
For this reason, we strongly encourage you to have your
system installed and calibrated by your dealer, whose
experience, training, and specialized equipment can
make a profound difference in the final performance of
the system.

7
Unpacking and Placement
unpacking your
integrated amplifier Carefully unpack your integrated amplifier according to the supplied
instructions, and remove all accessories from the carton.
Important! Keep all packing materials for future transport of your
Classé product. Shipping your new component in anything
other than its purpose-designed packing material may
result in damage that is not covered by the warranty.
placement As with any integrated amplifier, it is best to place the CAP-2100 centrally
within your system, since it is the hub to which all other components are
connected. It should also be located at a convenient height for both visibility and
use, since you generally interact with your integrated amplifier more than any
other component (changing inputs, adjusting volume, etc.).
Note that adequate clearance for the AC cord and connecting cables
must be left behind the CAP-2100. We suggest leaving eight inches
(20 cm) of free space behind your integrated amplifier to allow all cables
sufficient room to bend without crimping or undue strain.
Classé recommends that the unit not be placed directly on the top surface of a
power amplifier (or any other heat source).
ventilation Your Classé integrated amplifier generates a certain amount of heat in the course
of normal operation. Be sure to allow six inches of clearance above it and three
inches to each side to allow heat dissipation through air circulation. Avoid
placement on soft surfaces that would restrict airflow (such as plush carpeting).
custom installations Drawings are included in this manual to facilitate special installations and
custom cabinetry (see the section Dimensions). An optional, purpose-designed
rack mount kit is available for this product. Contact your Classé dealer for more
information.
serial number e serial number for your integrated amplifier is found on the rear of the
unit. Please note and record this number on the page entitled Important Safety
Instructions for your future reference.

8
register your purchase! Having found the serial number, now would be a good time to fill out the
registration card. Please register your purchase so we can advise you of updates
and other items of interest.
It will take only a minute or so. Please complete the card now, before you forget.
operating voltage e CAP-2100 integrated amplifier is set at the factory for 100V, 120V, 220V,
230V, or 240V AC mains operation, as appropriate for the country in which
it is to be sold (230V only in European Union countries, in compliance with CE
regulations.) e voltage setting may not be changed by the user.
Make sure that the label on the rear panel of your power amplifier indicates
the correct AC operating voltage for your location. Attempting to operate your
power amplifier at an incorrect voltage may damage the unit.
Warning: The voltage setting of your power amplifier may not
be changed by the user. There are no user-serviceable
parts within the unit. Please refer any problems to an
authorized Classé service center.
If the AC mains voltage indicated on your integrated amplifier is incorrect,
please contact your local, authorized Classé dealer or distributor.
e CAP-2100 can easily be powered by a normal 15-ampere AC mains line.
If other devices are also powered from the same AC line, their additional power
consumption should be taken into account.
e CAP-2100 includes protection circuitry that will prevent the integrated
amplifier from operating at dangerously high or low voltages.
• At startup: the AC mains voltage must be within a range of
approximately -15% to +10% of its nominal value at startup, or
the amplifier will not turn on. For example, a 120V unit requires
the AC mains to be between approximately 95V–135V in order to
turn on.
• Over-voltage during operation: if the AC mains voltage surges
by roughly 10% or more during operation, the amplifier will enter
protection mode and shut down. e Standby LED will flash to
indicate the protection mode has been engaged.
• Under-voltage during operation: if the AC mains voltage sags by
15% or more, the amplifier will continue to play (since this does
not present a particular danger to the amplifier), but note that
it may not be able to achieve its usual standard of performance
under these compromised conditions. e Standby LED will flash
to indicate the condition.

9
warm up/break-in period Your new Classé integrated amplifier will deliver outstanding performance
immediately. However, you should expect to hear it improve somewhat as
it reaches its normal operating temperatures and its various components
“break-in.” It has been our experience that the greatest changes occur within the
first 300 hours, as the integrated amplifier reaches thermal equilibrium and the
capacitors fully form. After this initial break-in period, the performance of your
new product should remain quite consistent for years to come.
e only exception to this rule is if the unit is unplugged for an extended period
of time, allowing it to cool down. Depending on the degree of cooling involved,
you should expect a brief warm-up period before the sound quality is at its best.
Unless your amplifier was allowed to become quite chilled, subsequent thermal
re-stabilization should not take long. Fortunately, you should never have to
repeat the initial 300 hour break-in period.
please read this manual… Please take a few minutes to review this manual, and to familiarize yourself
with your new integrated amplifier. We understand that you are anxious to plug
everything in and get started. However, reading this manual and following the
advice it gives will ensure that you get all the benefits you deserve from having
purchased such a fine piece of equipment.

10
Special Design Features
flexible graphical
user interface e LCD touchscreen on the front panel of your new component supports an
extremely flexible and versatile graphical user interface (GUI) while maintaining
a clean, uncluttered appearance. e CAP-2100 provides a range of controls
that might otherwise require dozens of buttons and knobs on the front panel.
Despite this power and flexibility, it remains simple to operate in day-to-day use.
In fact, in some ways it is even simpler to operate than a more conventional
design might be. For example, if you are not using one or more of the inputs on
your CAP-2100, you can delete the unnecessary buttons from the operational
menu. Doing so prevents anyone from trying to select a non-existent source
component, with the resulting confusion stemming from the lack of any sound.
(Of course, you can easily restore the button if you subsequently add another source
component and need that input.)
customizable
volume control e volume control on your new Classé integrated amplifier is controlled by
sophisticated software that allows you to fine-tune its response to suit your
preferences.
Ideally, a volume control would allow you to reach the volume you desire
quickly, and would also provide extremely fine control once you are close to the
“perfect” volume. Of course, these characteristics are in conflict with each other:
one requires the volume to change by quite a lot for a given amount of turning
of the knob, while the other requires small, incremental changes for the same
turn of the knob.
e volume control system on your CAP-2100 solves this problem by
responding differently based on the specific circumstances (e.g., how quickly you
are turning the knob and where in the volume range you are). After extensive
testing, we feel we have created factory default settings that most people will find
intuitive and a real pleasure to use. However, if you feel you would like to fine-
tune its performance further in order to suit your particular preference, you may
easily do so.
highly refined
circuit design All Classé analog amplification stages are based on circuits that have been
extensively optimized over many years of continuous development.
By starting with excellent circuit designs and working with them over the years,
we are able to discover the many small refinements that add up to superlative
performance, in a variety of applications. Altering a voltage here, or using a
slightly different part there, may make all the difference between solid and
absolutely outstanding performance.
is level of refinement only comes with a great deal of experience, and is not
available to those who flit from one trendy notion to the next. It accounts
in no small measure for both the consistency of sonic performance among
Classé products (as they are all based on similar analog gain stages), and for the
consistently excellent reviews these products receive from owners and reviewers
alike.

11
extensive listening tests Excellent measured performance is to be expected in world-class products, and
Classé products deliver that performance. However, experience has shown that
technical excellence alone is insufficient to guarantee subjectively musical results.
For this reason, all Classé products are laboriously fine-tuned during the
development process by carefully controlled listening tests. Our ears are still
some of the finest laboratory test instruments available, and nicely complement
more traditional engineering test equipment. In the course of optimizing the
circuitry for a product, hundreds of decisions are made based on the subjective
impression given by substituting one high quality part for another.
As an example, we may listen to half a dozen 0.1% tolerance film resistor
components of the same value, from several different companies. Standard tests
may show them all to provide identical results in terms of noise, distortion, and
so forth. Yet, almost invariably, one selection yields some small improvement in
the subjective reaction to the performance of the product under development.
Less often, even a single such change can result in a surprisingly large
improvement.
Multiply those various improvements by the dozens or even hundreds of such
decisions that must be made before the product can be finalized for production,
and you have a remarkable improvement, indeed – all based on careful listening
tests, which we view as a necessary complement to the solid engineering you
might rightly expect from Classé.
extraordinary longevity Another benefit of having worked with highly refined circuit designs so
extensively over many years is that we have vast experience in what works well
over the long term.
By using only the highest quality parts to begin with, and then using them in an
informed way as a result of both accelerated aging experiments and actual long-
term experience, we are able to design and manufacture products which we are
confident will stand the test of time.
We are confident that your new Classé integrated amplifier will give you many
years of trouble-free reliability and musical enjoyment, just as previous Classé
products have given their owners.

Front Panel
1 Standby button & LED indicator
e front panel Standby button will toggle the integrated amplifier
between operate, its fully operational state, and a standby mode that leaves
the integrated amplifier off, yet ready to respond to system commands via
any of the supported control options (e.g. IR input, DC trigger, CAN-Bus,
or RS-232).
e current state of the integrated amplifier is indicated by the LED on
the standby button on the front panel. When the unit is powered and
switched on, the state of this LED indicates the following:
• on = standby
• flashing (on power-up) = initialization
• off = operate
• on (dim) = display timeout
• flashing (after power-up) = AC mains voltage out of range
If you are planning not to use the integrated amplifier for an extended
period of time, e.g. vacation or other travel, we suggest you disconnect it
from the AC mains. Please be certain that the integrated amplifier is in
standby prior to disconnecting it from the AC mains.
Also, it is a good practice to physically disconnect any and all valuable
electronics from the AC mains during electrical storms, as a lightning strike
anywhere near your home can put a tremendous surge on the AC mains
that can damage any piece of electronics, no matter how well designed
and protected. e best protection in the case of severe electrical storms is
simply to remove the electronics from any connection with the power grid.

13
2 Menu button
Pressing the front panel Menu button will call up the main menu system,
replacing the normal operational menu and status display in the LCD
touchscreen.
3 LCD touchscreen
Much of your interaction with the CAP-2100 will be with the LCD
touchscreen (and the CAP-2100’s supplied remote control). It will usually
display the various input selection buttons you would use in day-to-day
operation, along with access to the tape button.
By pressing the Menu button, you can also call up the main menu system
of the CAP-2100, which gives you control over many of the operational
details of the integrated amplifier, including system setup options, various
display options (including the language in which the menu system itself
displays), and several custom-installation capabilities that allow superior
integration of the CAP-2100 into complex systems.
For more information, see the section e Menu System later in this
manual.
4 Mute button
e front panel Mute button reduces the volume of the integrated
amplifier to zero at the touch of a button. Pressing the button a second
time restores the volume to its previous setting.
However, if you increase the volume manually (using either the volume
knob or the remote control) while the Mute button is engaged, the mute
control will disengage and the volume will be set to zero. is approach
is a safety measure, to avoid situations in which the volume might be
adjusted up while muted, only to then have the system un-muted to an
unexpectedly high volume.
5 IR window
e infrared (IR) receiver and transmitter are located behind this
window. Ordinarily, your Classé CAP-2100 must be able to “see” the
remote control from this window in order to respond to remote control
commands.
If your integrated amplifier will be located behind closed doors, or for any
other reason will not be able to “see” the remote control during normal
operation, you may use the rear panel IR input and output mini-jacks and
an IR repeater system to solve the problem. For more information about
using an infrared repeater system to route signals to and from the
CAP-2100, refer to the section Rear Panel later in this manual, or contact
your local Classé dealer.

14
In addition to receiving IR commands, the CAP-2100 can also transmit IR
commands so they may be learned by third-party learning remote controls.
e CAP-2100 includes a comprehensive list of discrete IR commands
to facilitate the creation of reliable macros. Specifically, there are discrete
codes for all commands that normally operate as “toggle” functions
(e.g. separate operate and standby commands in addition to the normal
command that toggles between the two states).
6 Volume Knob
e large knob on the right side of the front panel of the CAP-2100 is
used to control the volume of the system.
e volume is raised or lowered in precise 0.5dB increments throughout
the range of the control most likely to be used while listening to music.
At extremely low volumes, the step size is increased somewhat to make it
easier to move quickly between extremely low and normal listening levels.

Rear Panel
1 Speaker Outputs
Two pairs of high quality five-way binding posts are provided on each
channel of the integrated amplifier, in order to facilitate bi-wiring.
In practice, bi-wiring involves connecting two (preferably identical) sets
of speaker cables between each amplifier channel and its corresponding
loudspeaker. In many cases, the benefit is a subjectively improved level of
clarity and detail from the speaker, as a result of being able to feed the two
separate sections of its crossover and driver complement with identical, yet
separate signals.
(Many high quality loudspeakers also offer two sets of connections on their
speakers. Generally, one set of the connections on the loudspeaker feeds
the portion of the speaker’s crossover network that supplies the woofer
with its signal; the other set of connections connects to the portion of the
crossover that supplies the rest of the speaker with the midrange and high
frequencies.)
Although the binding posts on your Classé amplifier will accept bare wire
connections, we strongly recommend the use of high quality spade or hook
lugs, crimped and soldered onto the ends of your speaker wires. Using
high quality connectors will ensure that your speaker connections do not
gradually deteriorate from fraying and oxidizing bare wires. It also helps
prevent accidental short-circuits from poorly-terminated connections.
2 Single-ended (RCA) main outputs
Single-ended cables using RCA connectors are the most common form
of analog connection used in consumer electronics. When implemented
carefully and used with high quality interconnect cables, this standard can
provide excellent performance.

16
Classé has gone to extraordinary effort to ensure that the single-ended
(RCA) outputs of your integrated amplifier are as good as possible.
If you need to use these preamplifier-level outputs, connect these single-
ended outputs to an amplifier using high-quality shielded RCA-terminated
cables. Your Classé dealer can advise you on the selection of cables suitable
for your system.
3 Tape output
Connect these outputs to the right-channel and left-channel recording
inputs of your recorder.
ese single-ended RCA outputs are unaffected by the volume control
on the front panel, or by whether you choose to monitor the source or
the recorder (by having the “tape” button on the front panel’s touchscreen
deselected or selected, respectively). e record outputs will be disconnected
when the integrated amplifier is placed into standby, however.
4 Tape Input
Connect the analog outputs of any recording device (analog tape recorder,
digital tape recorder, CD recorder, etc.) you may have to these single-ended
RCA inputs. You may select to hear the output of your recording device by
touching the tape monitor button on the main operational screen of the
CAP-2100.
5 Single-ended (RCA) inputs
ese RCA jacks accept right-channel and left-channel (single-ended)
inputs from line-level source equipment such as tuners, CD players,
and tape decks. Any of these inputs may be selected by touching the
corresponding button on the main operational screen of the front panel
touchscreen.
To achieve the best possible results, we suggest that you use only high-
quality shielded interconnect cables. Please consult with your local Classé
dealer for advice on the best cables for use in your system.
optional phono preamp If you have a turntable you would like to use with the system, an optional
phono preamplifier module is available from your Classé dealer. Once
installed in your integrated amplifier, the Line 1 input connectors become
your phono inputs, and the phono gain control in the menu system
becomes active, allowing you to select either low gain for all moving-
magnet (MM) and high-output moving-coil (MC) cartridges, or high gain
for standard output MC cartridges. (See the section e Menu System for
more information.)
6 Balanced (XLR) input
ese XLR jacks accept right-channel and left-channel balanced signals
from a source component with balanced outputs. is input may be
selected by touching the corresponding button on the main operational
screen of the front panel touchscreen.

17
e pin assignments of the XLR input connectors are:
Pin 1: Signal ground
Pin 2: Signal + (non-inverting)
Pin 3: Signal – (inverting)
Connector ground lug: chassis ground
ese pin assignments are consistent with the standard adopted by the
Audio Engineering Society (AES14-1992).
Refer to the operating manuals of your balanced-output line-level source to
verify that the pin assignments of its output connectors correspond to the
CAP-2100. If this is not the case, wire the cables so that the appropriate
output pin connects to the equivalent input pin.
To achieve the best possible results, we suggest that you use only high-
quality interconnect cables. Please consult with your local Classé dealer for
advice on the best cables for use in your system.
7 IR Input and Output
Your Classé integrated amplifier includes two 1/8th-inch mono mini-jacks
in order to support the infrared (IR) remote controls that are ubiquitous
today. Infrared commands exist (for example) for toggling the integrated
amplifier between operate and standby, in addition to discrete command
codes for either operate or standby. ese codes may be used in “macros”
for sophisticated remote control systems, facilitating the control of the
integrated amplifier in the larger context of a complete system.
e list of commands available is quite extensive, enabling even complex
macros (chains of commands strung together) to operate flawlessly. If this
capability is of interest to you, we strongly recommend discussing it with
your authorized Classé dealer.
Note that IR Input and Output is a bit of a misnomer: the input and
output of these plugs is electrical in nature, not infrared. ey are used
with standard IR receivers, distribution amplifiers, and emitters (available
from your dealer) to translate the remote’s IR signal to an electrical signal
and vice versa. e big advantages here include being able to easily route
the signals anywhere they might need to go and the reliability of a solid
electrical connection.
Since an IR distribution system such as your dealer may design for you
usually must control many products, your integrated amplifier includes
both an IR input (for the control of this product) and an IR output (so
as to pass along the same signal to the next product). is allows you to
“daisy chain” your control wires from one product to the next.
e integrated amplifier is designed to respond to IR commands of
5 VDC, with the tip of the mini-plug defined to be positive relative to the
shank of the plug.

18
8 Classé CAN-Bus Control Ports
ese RJ-45 connectors are reserved for future control and communication
applications using Classé Audio’s implementation of the Controller Area
Network (CAN) Bus specification.
9 RS-232 Control Port
is DB-9 connector has two purposes:
• downloading new operating software into your integrated
amplifier (should new features ever be added, for example)
• external control of your integrated amplifier by control systems
such as i-Command™, AMX®and Crestron™
For more information, please contact your dealer and ask about home
automation systems.
10 DC Trigger Input and Output
Many audio/video components can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
integrated amplifier can take advantage of these capabilities in order to be
switched between operate and standby automatically.
e 1/8th-inch mini-jack Trigger In provides for remote-controlled
turn-on (that is, toggling between operate and standby) of the integrated
amplifier.
Two 1/8th-inch mono mini-jacks provide individually controllable DC
trigger outputs which can be used for any of a number of purposes, as
described in e Menu System. For example, your dealer can program
Trigger Out1 to toggle an outboard Classé power amplifier between
operate and standby with your CAP-2100 (to facilitate the operation of
bi-amped systems).
e remote trigger input will respond to the presence of 5–12VDC, with
tip polarity as shown below:
Similarly, the trigger outputs will create a 12VDC signal that can support
up to 100mA of current.
11 Ground terminal
e ground terminal on your integrated amplifier is most often used for
the ground wire of a turntable, assuming you have the optional phono
module installed (see your authorized Classé dealer for more information
on this option if you are interested).
Connecting the ground wire from your turntable’s tonearm to this screw
terminal usually minimizes any hum or buzzing to which the turntable
might otherwise be susceptible. Your authorized Classé dealer can assist
you in handling this problem if it should arise.

12 AC Mains Fuse
An AC mains fuse holder is located next to the AC mains input. It is
unlikely that you should ever have to replace this fuse, but if you do, it is
critical that you do so only with a fuse of exactly the same rating and value
(specified in Troubleshooting #8).
Important! Never replace a blown fuse on this or any other piece of
electronics with anything other than a fuse of exactly the
same rating and value. Doing so can cause damage to your
electronics that may not be covered by the warranty. .
Always disconnect the integrated amplifier from the AC
mains and from the speakers before attempting to replace
a fuse. If the fuse blows again upon powering back up,
contact your authorized Classé dealer for assistance. .
There are no user-serviceable parts inside the CAP-2100.
13 AC Mains Input
An IEC standard power cord (supplied) is used with the CAP-2100.
Plug the cord into the IEC receptacle provided, and the other end into a
suitable wall outlet.
14 AC Mains Power Switch
e main power switch for the CAP-2100 is located near the middle of
the rear panel, beside the receptacle for the power cord.
e integrated amplifier should be in standby before being switched off.
Switching the unit on puts it in standby mode.
Danger! Potentially dangerous voltages and current capabilities
exist within your integrated amplifier, even when
disconnected from AC mains. Do not attempt to open any
portion of the integrated amplifier’s cabinet. There are no
user-serviceable parts inside your integrated amplifier.
All service of this product must be referred to a qualified
authorized Classé dealer or distributor.

The Remote Control
Your new integrated amplifier comes with a versatile remote control which can
control both the CAP-2100 itself and several aspects of the rest of a Classé-based
system. e buttons are arranged in logical groups according to their functions.
1 Basic Functions
is section along the top of the remote control groups four functions that
control your basic interactions with the CAP-2100.
• Light switches the backlighting of the remote control on, for
better visibility under low-light conditions. After a few moments
of inactivity, the backlight switches off automatically.
• Info takes you directly to the status screen in the LCD menu
system, displaying several items of information about the
CAP-2100 and its current operational status.
• Disp (for Display) cycles through the three brightness settings of
the screen display.
• Standby toggles the CAP-2100 between standby and operate.
2 Navigation Keys
e central section of the remote control contains the navigation keys. is
array of buttons is similar to what you may have seen on remote controls
for DVD players, and is used for navigation of the menu system of the
CAP-2100.
• Home returns you to the normal input selection controls
normally shown on the LCD screen on the front panel of the
CAP-2100. is provides a quick way to get back to normal
operation, regardless of how deep you might be in the menu
system.
• Menu serves two functions: it calls up the menu system when
you need it in order to adjust something to your preference;
once within the menu system, pressing Menu returns you to the
previous level of the menu system. If you press Menu when at
the top level of the menu system, it will take you back out of the
menu system to the normal display.
• Up/Down/Left/Right keys allow you to move within a
particular menu screen, changing the highlighted item up/down/
left/right as you like, from the comfort of your listening position.
• e Enter key allows you to select the highlighted item, having
the same effect as if you had pressed the button on the LCD
touchscreen.
• e Tape key is not a navigation key, per se, but allows you to
easily toggle between listening to the selected source and listening
to the output of your recording device. If you have a recording
device (such as a three-head tape deck) which can play back a
recording while it is being made, you will be able to compare the
original signal to the recording while you are making it.
