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.

ENGLISH

a word about installation Every effort has been made to make the Classé CA-5100 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.

unpacking your ampliﬁer Carefully unpack your power ampliﬁer according to the supplied instructions,

ENGLISH

Unpacking and Placement

and remove all accessories from the carton. Please take care when lifting the ampliﬁer, as it is quite heavy.

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 There are two options when placing your power ampliﬁer: you may place it close

to the speakers, requiring longer interconnecting cables from the preampliﬁer; or place it close to the preampliﬁer, requiring longer speaker cables.

Although either approach will yield excellent performance, you might consider the ﬁrst option for two reasons. First, signal quality degrades more easily when transmitted as a combination of both high voltage and high current, suggesting that speaker cables should be kept as short as practical. Second, high quality ampliﬁers use massive power supplies which inevitably radiate some degree of magnetic ﬁelds. Ideally, one would separate these ﬁelds from sensitive source components by a reasonable distance.

If it is more convenient for you to place the ampliﬁer in an equipment rack, along with your other components, we suggest placing it at the bottom of the rack, well away from your source components and preampliﬁer. This location will also be more stable than placing such a heavy component near the top of a rack, which might make it top-heavy.

Note that adequate clearance for the AC cord and connecting cables must be left behind the CA-5100. We suggest leaving eight inches (20 cm) of free space behind your power ampliﬁer to allow all cables sufﬁcient room to bend without crimping or undue strain.

ventilation Your Classé power 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. The vents on both the bottom and the top of the CA-5100 must be kept free from any obstruction which would reduce the ﬂow of air through the unit. 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 rack mount kit is available for this product. Contact your Classé dealer for more information.

ENGLISH

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 power ampliﬁer is incorrect, please contact your local, authorized Classé dealer or distributor.

The CA-5100 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.

ENGLISH

warm up/break-in period Your new Classé power ampliﬁer will deliver outstanding performance

The CA-5100 includes protection circuitry that will prevent the 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. The 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. The Standby LED ﬂash to indicate the condition.

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 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.

will

The only exception to this rule is if the unit is placed in standby 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 power ampliﬁer’s 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 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.

Special Design Features

ENGLISH

highly reﬁned

circuit design

extensive listening tests Excellent measured performance is to be expected in world-class products, and

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.

This 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 those products receive by owners and reviewers alike.

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% ﬁlm resistors 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.

ENGLISH

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 longterm 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 product will give you many years of trouble-free reliability and musical enjoyment, just as previous Classé products have given their owners.

robust protection Finally, your new Classé ampliﬁer incorporates a variety of protection circuits, all

designed to protect both the ampliﬁer and your loudspeakers against dangerous fault conditions. Signiﬁcantly, these protection circuits do not intrude upon or limit the normal performance of the ampliﬁer; rather, they simply put the ampliﬁer into protection mode when confronted with abnormal conditions. These conditions include:

• output overload

• DC offset

• AC mains voltage (outside of normal tolerances)

• excessive operating temperatures

If any of the ﬁrst three conditions occurs on either channel might harm either your ampliﬁer or possibly your loudspeakers), the ampliﬁer will immediately go into protection mode. In such a case, a will blink red, indicating the channel with the fault, and the sound will be muted until the fault can be righted.

If the fault is not channel-related, e.g. AC mains voltage out of range, the Standby LED will blink. In all cases, the unit will need to be re-started once the cause of the fault condition has been rectiﬁed.

ENGLISH

The current state of the ampliﬁer is indicated by the

LED indicator in the center of the Standby button. The state of this LED indicates the following:

• on = standby

• ﬂashing (on power-up) =

initialization

• off + Channel LED on = operate

• ﬂashing (after power-up) = AC mains voltage out of range

When in standby, the ampliﬁer’s gain stages are powered down. Only a small power supply and control circuit remain on, consuming relatively little power. Fortunately, since the output stages by their nature conduct a great deal of current, they warm up and sound their best very quickly.

If you are not going to use the ampliﬁer for an extended period of time, perhaps while traveling for a vacation, we suggest you disconnect it from the AC mains. Please be certain that the 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 easily damage any piece of electronics, no matter how well designed and protected. The best protection in the case of severe electrical storms is to simply remove the electronics from any connection with the power grid.

ENGLISH

2 Select button

The Select button is used (along with the Mode button) when conﬁguring the ampliﬁer for either balanced or single-ended operation. It is also used when conﬁguring the turn-on delay or ampliﬁer number for an ampliﬁer connected to a Classé preampliﬁer by the DC Trigger or CAN Bus control systems.

3 Channel status LED indicators

Each ampliﬁer channel has two indicate the use of either balanced (XLR) or single-ended (RCA) inputs for that channel.

These indicators are also used to indicate fault conditions in your ampliﬁer, should any ever arise. If a channel’s LED indicators blink red, there is a problem in that particular channel. If all the red, there may be a systemic problem that is not speciﬁc to a particular channel.

Caution! If you see any Channel LED Indicator blinking red, please

disconnect the ampliﬁer from the AC mains immediately and check that all external connections are cleanly made and secure. If the AC mains are not easily accessible, you can press and hold the Standby button for three seconds to reset the ampliﬁer. If no fault is immediately obvious, please call your authorized Classé dealer for assistance.

Rear Panel

The following descriptions are intended as a quick reference, should you have any questions about your new product. Please see the next section (entitled Initial Setup) for speciﬁc advice on incorporating your new ampliﬁer into your system.

ENGLISH

1 Balanced (XLR) Input

Balanced audio interconnections were originally developed in the professional audio world, for preserving the delicate nuances of extremely small microphone-level signals. For many years now, they have also been used by performance-oriented consumer companies like Classé to preserve every nuance of the ﬁnest audio performances in your collection.

Technically, balanced audio interconnections provide two distinct beneﬁts: they double the signal’s strength as it travels from one component to the next, increasing the potential signal to noise ratio by 6 dB; they also do an excellent job of rejecting noise and interference that might otherwise be picked up between the components, due to either EMI (electromagnetic interference) or RFI (radio frequency interference). In the world of wireless telecommunications, there is more potential interference around than ever before—it makes sense to keep it out of music and movie soundtracks.

For this reason, we strongly recommend using the balanced analog interconnections between your Classé components wherever possible.

ENGLISH

The pin assignments of these XLR input connectors are:

Pin 1: Signal ground Pin 2: Signal + (non-inverting) Pin 3: Signal – (inverting) Connector ground lug: chassis ground

These pin assignments are consistent with the standard adopted by the Audio Engineering Society (AES14-1992).

If you are using your Classé power ampliﬁer with a Classé preampliﬁer, you’re all set – just take standard balanced interconnect cables and plug them in.Then engage that input on the power ampliﬁer by conﬁguring it as described in Initial Setup.

If you are using another brand of preampliﬁer, please refer to the operating manual of your balanced-output preampliﬁer to verify that the pin assignments of its output connectors correspond to your ampliﬁer. If not, have your dealer wire the cables so that the appropriate output pin connects to the equivalent input pin.

2 Single-Ended (RCA) Input

Single-ended cables using RCA connectors are the most common form of analog connection used in consumer electronics. When implemented carefully and with use of high quality interconnecting cables, this standard can provide excellent performance. Classé has gone to extraordinary effort to ensure that the single-ended (RCA) inputs of your power ampliﬁer are as good as possible. However, this connection standard cannot offer the immunity from interference that balanced interconnection does—hence our recommendation to use the balanced inputs when possible.

If you elect to use the single-ended inputs of your Classé power ampliﬁer, you need to engage them by conﬁguring the ampliﬁer as described in

Initial Setup

3 Speaker Outputs

A pair of high quality ﬁve-way binding posts is provided for each channel of the ampliﬁer.

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.

4 Classé CAN Bus Control Ports

These RJ-45 connectors are reserved for future control and communication applications using Classé Audio’s implementation of the Controller Area Network (CAN) Bus speciﬁcation.

ENGLISH

5 IR Input and Output

1/8th

Your Classé ampliﬁer includes two

-inch mini mono-jacks in order to support the IR remote controls that are ubiquitous today. IR commands exist for toggling the ampliﬁer between operate discrete command codes for either operate

and standby, as well as

or standby. These codes may be used in “macros” for sophisticated remote control systems, facilitating the control of the ampliﬁer in the larger context of a complete system.

Actually, this IR Input and Output

description is a bit of a misnomer: the input supplied to these plugs is electrical in nature, not IR. It is obtained by using standard IR receivers, distribution ampliﬁers, and emitters (available from your dealer) to translate the remote’s ﬂashes of infrared light into corresponding pulses of electricity. The 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 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). This allows you to “daisy chain” your control wires from one product to the next.

The ampliﬁer is designed to respond to IR commands of 5 Volts DC, with the tip of the mini mono-plugs deﬁned to be “positive” relative to the shank of the plug.

ENGLISH

6 DC Trigger Input and Output

Many audio/video preampliﬁers can supply a DC control voltage to associated equipment in order to induce desired behavior. Your Classé ampliﬁer can take advantage of these capabilities in order to be switched between operate

and standby automatically, perhaps in concert with the

A/V preamp itself.

Two (that is, toggling between operate

-inch mini mono-jacks provide this remote-controlled turn-on and standby) of the ampliﬁer. These jacks

provide a simple pass-through of the control voltage from one to the other, allowing you to “daisy-chain” a series of ampliﬁers quite easily.

The remote trigger will be operated by the presence of 5–12 Volts DC, with tip polarity as shown below:

7 RS-232 Control Port

This DB-9 connector has two purposes:

• downloading new operating software into your ampliﬁer (should new features ever be added, for example)

• for external control of your ampliﬁer by systems such as i-Command™, AMX® and Crestron

™

For more information, please contact your dealer and ask about home automation systems.

8 AC Mains Input

An IEC standard power cord is used with the CA-5100. Plug the cord into the IEC receptacle on the rear panel, and the other end into a suitable wall outlet.

9 AC Mains Fuse

Your Classé power ampliﬁer has an AC mains fuse, accessible on the rear panel. If you suspect that your AC fuse has blown, disconnect your ampliﬁer from the AC mains, as well as from its input connections and speaker connections, and refer to the appropriate item of the section entitled Troubleshooting.

Do not open your ampliﬁer. There are no user-serviceable parts within this product.

Danger! Potentially dangerous voltages and current capabilities exist

within your power ampliﬁer, even when disconnected from AC mains. Do not attempt to open any portion of the ampliﬁer’s cabinet. There are no user-serviceable parts inside your power ampliﬁer. All service of this product must be referred to a qualiﬁed Classé dealer or distributor.

ENGLISH

Initial Setup

Your new Classé ampliﬁer is quite simple to set up and enjoy. Please follow the steps outlined below in order to safely set up and use your new ampliﬁer.

Important: The AC mains connection should be the last connection you

make on your new power ampliﬁer. In addition, it is always a good idea to power up your power ampliﬁer(s) last, after everything else has been powered up and has stabilized.

Conversely, it is good practice to power the ampliﬁer(s) down ﬁrst when shutting down the system, as this prevents any transients from other components from getting through to your loudspeakers.

1. Unpack everything according to the included instructions.

Be careful when doing so, as this ampliﬁer is quite heavy.

2. Place your ampliﬁer (be sure to read “Unpacking and Placement”) and connect it to the AC mains.

This includes deciding on the location, making sure you have adequate ventilation, and adequate clearance for all the wires behind the ampliﬁer. Once accomplished, connect the ampliﬁer directly to the AC mains. Do not use extension cords, as most are not suitable for the current sometimes required by your ampliﬁer.

conﬁguring balanced/

single-ended operation

3. Conﬁgure your ampliﬁer.

The Select and Mode buttons are used when conﬁguring your ampliﬁer for how you would like it to operate.

While in standby, pressing the Select button will cause the Channel LEDs to light up, indicating how the ampliﬁer is currently conﬁgured (either balanced or single-ended) for each channel.

One of the may select either balanced or single-ended operation for that channel. Press the Mode button to toggle between either the balanced mode or the singleended mode of operation, as indicated by which of the two channel LEDs for that channel is blinking.

Press the Select button again to select the next channel, and repeat the pro cess until the ampliﬁer is conﬁgured as you desire. To ﬁnish, continue to press and release the Select

Make sure you conﬁgure the ampliﬁer to use the type of input connection you will be using for each channel. You may safely use any combination of single-ended and balanced input connections your system requires.

Channel LED indicators will be blinking, indicating that you

conﬁguring ampliﬁer

turn-on delay/amp no.

In a system that contains multiple Classé ampliﬁers, you may set the number of seconds of turn-on delay for each ampliﬁer, allowing each to turn on in the order you have speciﬁed, rather than all at once. (Having

several powerful ampliﬁers all turning on at the same time can sometimes stress the AC mains in your home, potentially leading to nuisance tripping of circuit breakers). This number also acts as an ID when using the CAN Bus.

For example, to set the delay for two seconds (and to designate a particular ampliﬁer as #2):

ENGLISH

• Place the ampliﬁer in standby

• Press and hold the Mode When released, the LEDs will blink to indicate the turn-on delay and current number of the ampliﬁer (e.g. once to indicate a one second delay and ampliﬁer #1).

• If you want to change the current ampliﬁer number setting, press and hold the Mode button again until the Channel LEDs are on.

• While continuing to hold the Mode button, press the Select button two times (the same number as the desired delay in seconds and the ampliﬁer number);

• Release the Mode button. The ampliﬁer will conﬁrm your choice by blinking the Channel LEDs twice.

4. Make your preamp connections.

With the ampliﬁer in standby (or disconnected from the AC mains), and using high quality interconnecting cables, make the appropriate connections with the balanced or single-ended connectors (as conﬁgured in

button until the Channel LEDs are lit.

5. Make your speaker connections.

Make the connection between the output terminals of the ampliﬁer and your loudspeakers, using high quality speaker wires.

Connect the black (–) terminals on the ampliﬁer to the black (–) terminals on your speaker, and the red (+) terminals on the ampliﬁer to the red (+) terminals on your speaker.

If bi-wiring, run a total of four conductors between each ampliﬁer channel and its corresponding loudspeaker: two separate +/– leads, one for the bass and the other for the mids and treble. Make sure that no wires cross between the red (+) and black (–) terminals, at either end.

Make sure all the connections are snug and cannot be easily wiggled free, but do not overtighten them. If you can give the speaker wires a reasonable tug without movement, they are snug. Further tightening will not make a better connection, and (taken to the extreme) may damage the connectors.

6. Double-check all your connections.

We understand that this step sounds redundant, but it is worth the extra minute or two it might take just to ensure that all connections are correct and secure before plugging the power cables to the AC outlets..

ENGLISH

7. Turn on all the other components in your system, and then turn on your ampliﬁer.

It is always good practice to turn any power ampliﬁer on last, and to turn it off ﬁrst. Doing so prevents any turn-on/turn-off transients that might originate in other components from damaging your loudspeakers.

Care and Maintenance

To remove dust from the cabinet of your ampliﬁer, use a feather duster or a lintfree soft cloth. To remove dirt and ﬁngerprints, we recommend isopropyl alcohol and a soft cloth. Dampen the cloth with alcohol ﬁrst and then lightly clean the surface of the ampliﬁer with the cloth. Do not use excessive amounts of alcohol that might drip off the cloth and into the ampliﬁer.

Caution! At no time should liquid cleaners be applied directly to

the ampliﬁer, as direct application of liquids may result in damage to electronic components within the unit.

Troubleshooting

In general, you should refer any service problems to your Classé dealer. Before contacting your dealer, however, please check to see if the problem is listed here.

1. No sound, and no Channel LED is lit.

• The ampliﬁer is not plugged into the AC mains, or the AC mains are down (circuit breaker, fuse).

• A brown-out or short-term loss of power might require the internal microprocessor to be reset. Unplug the unit for at least 30 seconds and then plug it in again and try powering it up.

• The AC mains fuse is blown. See Troubleshooting #4, below (or contact your Classé dealer).

• The AC mains is out of range. Check the voltage speciﬁed on the rear panel.

2. No sound, and one or more Channel LEDs is blinking red.

• Your protection circuitry may have been engaged. To reset the ampliﬁer, press and hold the Standby button for 3 seconds to power down the ampliﬁer. Then disconnect all inputs and outputs.

• Then try powering up the ampliﬁer by pressing the Standby button. If the in the ampliﬁer itself. It should be powered down, disconnected from the AC mains and taken to your Classe dealer for service.

• If it powers up without any difﬁculty, power it back down and reconnect only the inputs. Then restart the ampliﬁer. If it goes into its blinking protection mode, something is wrong with a component “upstream” of the ampliﬁer—probably a DC offset or similar problem. Your ampliﬁer is trying to protect your loudspeakers (even small amounts of DC can damage woofers in relatively little time). Try different source components to discover whether the problem is limited to a single source, or exists all the time (which would indicate a problem with the preampliﬁer). Contact your dealer for help with the appropriate component.

LED continues to blink, there is a fault condition

ENGLISH

3. The ampliﬁer keeps shutting off.

• Make sure you are providing adequate ventilation to the ampliﬁer, and that the ambient room temperature is below 105°F (40°C).

• Run through the troubleshooting sequence outlined above (assuming the ampliﬁer is going into its protection mode).

4. The AC mains fuse is blown.

There is a speciﬁc troubleshooting procedure for a blown AC mains fuse, since this rare occurrence sometimes indicates a signiﬁcant problem. Please follow the following steps, in order:

ENGLISH

a. Disconnect your ampliﬁer from the AC mains, as well as from its

input connections and speaker connections, and remove the fuse cover on the rear of the unit.

b. If the fuse appears to be blown, replace it only with a fuse of

the same type and rating (speciﬁed below). Using any other type

of fuse, particularly a larger-value fuse, can result in permanent damage to your ampliﬁer. If you are uncomfortable replacing the

fuse yourself, contact your Classé dealer for assistance.

Mains voltage: 100/120VAC Fuse type: MDA slo-blow Rating: 12A

Mains voltage: 230/240VAC Fuse type: MDA slo-blow Rating: 10A

c. After replacing the fuse and fuse cover, reconnect the ampliﬁer to

the AC mains only and turn it on without reconnecting either the inputs or the speaker wires. If the fuse blows again, disconnect it from the AC mains and contact your Classé dealer for assistance.

d. If everything seems ﬁne, place the ampliﬁer back into standby

and carefully reconnect the input cable and power the ampliﬁer up. If the fuse then blows (or the ampliﬁer goes into protection), you may have a serious fault with your preampliﬁer/processor. Contact your Classé dealer.

e. Finally, if everything is still ﬁne, place the ampliﬁer in standby

and carefully reconnect the speaker wires. Check the speaker wires for possible short circuits. Then power up the ampliﬁer again. If the ampliﬁer remains functional (the fuse does not blow), then the original fuse probably blew in order to protect the ampliﬁer from a large AC mains surge. If it blows again, contact your Classé dealer for assistance.

5. The Standby LED is ﬂashing quickly, and a Channel LED is ﬂashing red.

• Try resetting the unit by disconnecting it from the AC mains power, waiting a few seconds, and reconnecting the ampliﬁer to power. If this does not solve the problem, contact your Classé dealer for assistance.

: soir près des enceintes acoustiques, ce qui sous-entend de longs câbles de connexion avec le préampliﬁcateur ; soit près du préampliﬁcateur, ce qui sousentend de longs câbles vers les enceintes acoustiques.

Bien que ces deux solutions puissent donner d’excellents résultats, nous vous suggérons plus volontiers de choisir la première, et ce pour deux raisons. Premièrement, la qualité du signal se dégrade plus rapidement lorsque celui-ci doit véhiculer simultanément une tension et un courant élevés, ce qui sousentend que les câbles des enceintes acoustiques doivent être les plus courts possibles. Deuxièmement, les ampliﬁcateurs de très haute qualité utilisent des alimentations surdimensionnées qui génèrent inévitablement une certaine dose de rayonnement magnétique. Or, ceux-ci doivent théoriquement rester raisonnablement éloignés des maillons-sources les plus sensibles.

L’installation la plus simple se trouve dans un meuble-rack spécial, à côté des autres maillons ; nous vous conseillons de le placer au pied du rack, au-dessous du préampliﬁcateur et des diverses sources, dont il sera ainsi le plus éloigné. Cet emplacement garantit aussi une meilleure stabilité au meuble, puisque c’est certainement l’élément le plus lourd qui y est posé.

Notez qu’une longueur sufﬁsante doit être prévue pour tous les câbles de liaison et le câble d’alimentation secteur, derrière le CA-5100. Nous vous suggérons de laisser un espace d’au moins 20 centimètres derrière l’ampliﬁcateur de puissance pour permettre leur passage sans risque de torsion ou d’arrachage.

aération Votre ampliﬁcateur de puissance Classé génère une certaine quantité de chaleur,

en fonctionnement normal. Laissez un espace d’une quinzaine de centimètres tout autour de l’appareil et au-dessus de lui, aﬁn de permettre la dissipation de cette chaleur par simple circulation d’air. Évitez de le poser sur une surface nonplane (tapis, par exemple).

Assurez-vous que l’étiquette présente en face arrière indique bien la tension d’alimentation présente à votre domicile. Une mauvaise tension d’alimentation peut endommager votre appareil irrémédiablement.

Attention: Le réglage de la tension d’alimentation secteur de votre

appareil ne peut être modiﬁé par vos soins. Il n’y a pas

de pièces susceptibles d’être modiﬁées par l’utilisateur

à l’intérieur de l’appareil. Veuillez vous adresser à un

technicien agréé par Classé (revendeur).

Si la tension d’alimentation indiquée n’est pas correcte, contactez immédiatement votre revendeur agréé Classé.

Le CA-5100 peut être alimenté sans problème sur une ligne électrique domestique de courant alternatif 15 ampères. Si d’autres appareils sont branchés sur cette même ligne, leur consommation respective doit toutefois être prise en compte.

FRANÇAIS

Le CA-5100 possède un circuit de protection contre les variations importantes de tension, à la hausse comme à la baisse.

• Au démarrage : la tension d’alimentation doit se trouver dans une fourchette comprise entre approximativement – 15 % et + 10 % de sa valeur nominale, sinon l’appareil ne s’allumera pas. Par exemple, un appareil conçu pour fonctionner sur 120 V requiert une tension d’alimentation effective comprise entre 95 et 135 V pour s’allumer.

• Surtension pendant le fonctionnement : si la tension d’alimentation augmente de 10 % ou plus pendant le fonctionnement, l’appareil se met en mode de protection et s’éteint automatiquement. La diode de mise en veille Standby clignote pour indiquer la mise en service de la protection.

• Sous-tension pendant le fonctionnement : si la tension d’alimentation baisse de 15 % ou plus, l’appareil continue de fonctionner (à moins que cela ne présente un danger particulier pour lui), mais il ne sera plus capable de fournir les performances optimales pour lesquelles il a été conçu. La diode Standby LED se met à clignoter pour indiquer le problème.

période de rodage Votre nouvel ampliﬁcateur de puissance Classé ne délivrera pas la quintessence

de ses performances immédiatement. Vous constaterez une première amélioration quand l’appareil aura atteint sa température normale de fonctionnement, tous ses composants internes étant alors « stabilisés ». Selon notre expérience, les changements les plus importants surviennent après environ 300 heures de fonctionnement, après que l’appareil ait atteint son équilibre thermique parfait et que ses condensateurs soient parfaitement efﬁcaces. Une fois cette période de rodage passée, votre nouveau maillon conservera ses performances optimales pendant des années.

LED

La seule exception à cette règle concerne la situation pendant laquelle l’appareil est laissé en veille ou débranché de l’alimentation secteur pendant une longue période, ce qui se traduit par son refroidissement. Alors, suivant la durée nécessaire pour qu’il revienne à sa température de fonctionnement normale, vous devrez attendre une brève période de rodage pour qu’il retrouve ses meilleures performances sonores. Mais cette remise en température n’est alors jamais très longue. Vous n’aurez fort heureusement jamais à répéter les 300 heures de période de rodage initial.

veuillez lire ce manuel... Prenez les quelques minutes nécessaires à la lecture de ce manuel, aﬁn de vous

familiariser avec votre nouvel ampliﬁcateur de puissance. Nous comprenons que vous soyez impatient de brancher et d’allumer votre nouvel appareil. Mais, en lisant ce manuel et en suivant tous les conseils qui y sont prodigués, vous serez certains d’en tirer le meilleur proﬁt et comprendrez comment tirer tout le parti de ce véritable investissement de très haute qualité.
