Welcome to the Classé family

Congratulations on your purchase of a Classé product. It is the result of many
years of continuous re–nement, 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 –nd 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 CA-2200 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 ampli–er. All of these factors in—uence 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.

ENGLISH

Unpacking and Placement

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

and remove all accessories from the carton. Please take care when lifting the
ampli–er, 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 ampli–er: you may place it close

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

Although either approach will yield excellent performance, you might consider
the –rst 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
ampli–ers use massive power supplies which inevitably radiate some degree of
magnetic –elds. Ideally, one would separate these –elds from sensitive source
components by a reasonable distance.

If it is more convenient for you to place the ampli–er 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 preampli–er. 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-2200. We suggest leaving eight inches
(20 cm) of free space behind your power ampli–er to allow all cables
suf–cient room to bend without crimping or undue strain.

ventilation Your Classé power ampli–er 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-2200 must be kept free from
any obstruction which would reduce the —ow of air through the unit. Avoid
placement on soft surfaces that would restrict air—ow (such as plush carpeting).

ENGLISH

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 The serial number for your power ampli–er 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.

register your purchase! Having found the serial number, now would be a good time to –ll 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 The CA-2200 power ampli–er is set at the factory (internally) for 100V, 120V,

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). The voltage setting may not be changed by the user or dealer.

Make sure that the label on the rear panel of your power ampli–er indicates
the correct AC operating voltage for your location. Attempting to operate your
power ampli–er 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 ampli–er is incorrect, please
contact your local, authorized Classé dealer or distributor.

The CA-2200 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.

8

ENGLISH

The CA-2200 includes protection circuitry that will prevent the ampli–er 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 ampli–er 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 ampli–er will enter
protection mode and shut down. The Standby LED will —ash to
indicate the protection mode has been engaged.

• Under-voltage during operation: if the AC mains voltage sags by
15% or more, the ampli–er will continue to play (since this does
not present a particular danger to the ampli–er), but note that
it may not be able to achieve its usual standard of performance
under these compromised conditions. The Standby LED will
—ash to indicate the condition.

warm up/break-in period Your new Classé power ampli–er 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
–rst 300 hours, as the ampli–er 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.

The only exception to this rule is if the unit is placed in standby or 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
power ampli–er»s sound quality is at its best. Unless your ampli–er 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 ampli–er. 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 bene–ts you deserve from having purchased such
a –ne piece of equipment.

Special Design Features

highly refined

circuit design

All Classé analog ampli–cation 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 re–nements 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 re–nement only comes with a great deal of experience, and is
not available to those who —it 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.

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 insuf–cient to guarantee subjectively musical results.

For this reason, all Classé products are laboriously –ne-tuned during the
development process by carefully controlled listening tests. Our ears are still
some of the –nest 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% –lm 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 –nalized for production,
and you have a remarkable improvement, indeedƒall based on careful listening
tests, which we view as a necessary complement to the solid engineering you
might rightly expect from Classé.

10

ENGLISH

extraordinary longevity Another bene–t of having worked with highly re–ned 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
con–dent will stand the test of time.

We are con–dent 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 ampli–er incorporates a variety of protection circuits, all

designed to protect both the ampli–er and your loudspeakers against dangerous
fault conditions. Signi–cantly, these protection circuits do not intrude upon
or limit the normal performance of the ampli–er; rather, they simply put the
ampli–er 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 –rst three conditions occurs on either channel (any of which
might harm either your ampli–er or possibly your loudspeakers), the ampli–er will
immediately go into protection mode. In such a case, a Channel LED indicator
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 recti–ed.

11

ENGLISH

Front Panel

1 Standby button & LED indicator

The front panel Standby button will toggle the ampli–er between operate,
its fully operational state, and a standby mode that leaves the ampli–er 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).

The current state of the ampli–er is indicated by the LED indicator in
the center of the Standby button. The state of this LED indicates the
following:

• on = standby

• —ashing (on power-up) = initialization

• off + Channel LED on = operate

• —ashing (after power-up) = AC mains voltage out of

range

When in standby, the ampli–er»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 ampli–er 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 ampli–er is in standby prior to
disconnecting it from the AC mains.

12

ENGLISH

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.

2 Select button

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

3 Channel status LED indicators

Each ampli–er channel has two Channel LED indicators. They are used to
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 ampli–er,
should any ever arise. If a channel»s LED indicators blink red, there is a
problem in that particular channel. If all the Channel LEDs are blinking
red, there may be a systemic problem that is not speci–c 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.

4 Mode button

The Mode button is used (along with the Select button) when con–guring
the ampli–er for either balanced or single-ended operation. It is also
used when con–guring the turn-on delay and ampli–er number of the
ampli–er when it is connected to a Classé preampli–er by the CAN Bus
communications or Trigger systems.

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 speci–c advice on incorporating your new ampli–er into your
system.

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 –nest audio performances in your collection.

Technically, balanced audio interconnections provide two distinct bene–ts:
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.

14

ENGLISH

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

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 ampli–er with a Classé preampli–er,
you»re all set √ just take standard balanced interconnect cables and plug
them in.Then engage that input on the power ampli–er by con–guring it
as described in Initial Setup.

If you are using another brand of preampli–er, please refer to the operating
manual of your balanced-output preampli–er to verify that the pin
assignments of its output connectors correspond to your ampli–er. 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 ampli–er are
as good as possible. However, this connection standard cannot offer the
immunity from interference that balanced interconnection doesƒhence
our recommendation to use the balanced inputs when possible.

If you elect to use the single-ended inputs of your Classé power ampli–er,
you need to engage them by con–guring the ampli–er as described in
Initial Setup.

3 Speaker Outputs

Two pairs of high quality –ve-way binding posts are provided on the
ampli–er, in order to facilitate ≈bi-wiring.∆

In practice, bi-wiring involves connecting two (preferably identical) sets
of speaker cables between each ampli–er channel and its corresponding
loudspeaker. In many cases, the bene–t 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.

15

ENGLISH

(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 ampli–er 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 speci–cation.

5 IR Input and Output

Your Classé ampli–er includes two 1/8th-inch mini mono-jacks in order to
support the IR remote controls that are ubiquitous today. IR commands
exist for toggling the ampli–er between operate and standby, as well as
discrete command codes for either operate or standby. These codes may be
used in ≈macros∆ for sophisticated remote control systems, facilitating the
control of the ampli–er 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 ampli–ers, and emitters (available
from your dealer) to translate the remote»s —ashes 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 ampli–er 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 ampli–er is designed to respond to IR commands of 5 Volts DC,
with the tip of the mini mono-plugs de–ned to be ≈positive∆ relative to the
shank of the plug.

16

ENGLISH

6 DC Trigger Input and Output

Many audio/video preampli–ers can supply a DC control voltage to
associated equipment in order to induce desired behavior. Your Classé
ampli–er 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 1/8th-inch mini mono-jacks provide this remote-controlled turn-on
(that is, toggling between operate and standby) of the ampli–er. These jacks
provide a simple pass-through of the control voltage from one to the other,
allowing you to ≈daisy-chain∆ a series of ampli–ers 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 ampli–er (should

new features ever be added, for example)

• for external control of your ampli–er 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-2200. 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 ampli–er has an AC mains fuse, accessible on the
rear panel. If you suspect that your AC fuse has blown, disconnect your
ampli–er from the AC mains, as well as from its input connections and
speaker connections, and refer to the appropriate item of the section
enitled Troubleshooting.

Do not open your ampli–er. There are no user-serviceable parts within
this product.

17

ENGLISH

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.

18

ENGLISH

Initial Setup

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

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 ampli–er 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 ampli–er.
Once accomplished, connect the ampli–er directly to the AC mains. Do
not use extension cords, as most are not suitable for the current sometimes
required by your ampli–er.

3. Configure your amplifier.

The Select and Mode buttons are used when con–guring your ampli–er
for how you would like it to operate.

configuring balanced/

single-ended operation

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

One of the Channel LED indicators will be blinking, indicating that you
may select either balanced or single-ended operation for that channel. Press
the Mode button to toggle between either the balanced mode or the
single-ended 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 other channel, and press the
Mode button to select the con–guration for that channel.

To –nish, press and release the Select button until both Channel LEDs are
off.

Make sure you con–gure the ampli–er to use the type of input connection
you will be using.

19

ENGLISH

configuring amplifier

turn-on delay/amp no.

In a system that contains multiple Classé ampli–ers, you may set the
number of seconds of turn-on delay for each ampli–er, allowing each
to turn on in the order you have speci–ed, rather than all at once. This

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

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

• Place the ampli–er in standby (Standby LED on)

• Press and hold the Mode button until both Channel LEDs are
lit. When released, both LEDs will blink to indicate the turn-on
delay and current number of the ampli–er (e.g. once to indicate a
one second delay and ampli–er #1).

• If you want to change the current ampli–er number setting, press
and hold the Mode button again until both 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 ampli–er number);

• Release the Mode button. The ampli–er will con–rm your choice
by blinking the Channel LEDs twice.

4. Make your preamp connections.

With the ampli–er 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 con–gured in
Step 3).

Make sure all the connections are snug, even if it means gently squeezing
the outer shell of the RCA with pliers and reinserting it to tighten the
connection.

5. Make your speaker connections.

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

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

If bi-wiring, run a total of four conductors between each ampli–er 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.

20

ENGLISH

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..

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 ampli–er on last, and to turn
it off –rst. 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 ampli–er, use a feather duster or a lint­free soft cloth. To remove dirt and –ngerprints, we recommend isopropyl alcohol
and a soft cloth. Dampen the cloth with alcohol –rst and then lightly clean the
surface of the ampli–er with the cloth. Do not use excessive amounts of alcohol
that might drip off the cloth and into the ampli–er.

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.

ENGLISH

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 ampli–er 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 speci–ed 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
ampli–er, press and hold the Standby button for 3 seconds
to power down the ampli–er. Then disconnect all inputs and
outputs.

• Then try powering up the ampli–er by pressing the Standby
button. If the LED continues to blink, there is a fault condition
in the ampli–er 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 dif–culty, power it back down and
reconnect only the inputs. Then restart the ampli–er. If it goes
into its blinking protection mode, something is wrong with a
component ≈upstream∆ of the ampli–erƒprobably a DC offset
or similar problem. Your ampli–er 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 preampli–er).
Contact your dealer for help with the appropriate component.

3. The amplifier keeps shutting off.

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

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

22

ENGLISH

4. The AC mains fuse is blown.

There is a speci–c troubleshooting procedure for a blown AC mains fuse,
since this rare occurrence sometimes indicates a signi–cant problem. Please
follow the following steps, in order:

a. Disconnect your ampli–er 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 (speci–ed below). Using any other type

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

fuse yourself, contact your Classé dealer for assistance.

Mains voltage: 100/120VAC
Fuse type: MDA slow-blow
Rating: 10A

Mains voltage: 230/240VAC
Fuse type: MDL slow-blow
Rating: 8A

c. After replacing the fuse and fuse cover, reconnect the ampli–er 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 –ne, place the ampli–er back into standby

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

e. Finally, if everything is still –ne, place the ampli–er in standby

and carefully reconnect the speaker wires. Check both ends of
the speaker wires for possible short circuits. Then power up the
ampli–er again. If the ampli–er remains functional (the fuse
does not blow), then the original fuse probably blew in order to
protect the ampli–er 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 ampli–er to
power. If this does not solve the problem, contact your Classé
dealer for assistance.

关于安装的提示 我们已经竭尽全力使 Classé CA-2200 型功率放大器的安装和使用更加简

单、易懂。

但是，我们仍然无法估计其它许许多多的变量因素，比如你房间的大小
和形状，房间的声学条件，以及你所选择的放在房间里与功放一同使用
的其它相关设备。所有这些因素都会影响功放系统的最终播放效果。

出于这个原因，我们强烈建议你请设备的经销商为你安装本

系统并进行校准，他们经过训练，具备专业安装工具再加上

拆包和安放

拆开放大器

的包装

根据提供的拆包说明，小心拆开功放的包装，并把所有的零部件从包装
纸盒中拿出来。当你在拿放大器的时候，请小心一点，因为放大器重量
很重。

重要： 请保留好包装材料，以便将来搬运你的 Classé 产品。除了专

门用来包装本产品的包装材料，使用任何其它包装材料来搬
运你的设备都可能会导致损坏，这不包含在保修范围之内。

安放 安放功率放大器有两种选择：你可以把它安放在扬声器的旁边，这就需

要更长点的互连接线，连接到前置放大器上；还有一种选择就是，把它
安放在前置放大器的旁边，就需要更长点的扬声器接线，用来连接到扬
声器。

虽然这两种安放方法都会有出色的效果，但你可以先考虑第一种选择，
因为：第一，当设备以高电压和高电压的组合进行传输信号时，信号的
质量会更加容易受到干扰，我们建议扬声器的接线根据实际情况，越短
越好；第二，高质量的功放要使用大量的电源，这就必然会产生一定程
度的磁场。理论上来说，可以通过保持适当的距离，可以把这些磁场分
离敏感的源设备。

如果方便的话，你可以把功放连同其它设备一起安放在一个设备架子
上，建议你把它置于设备架的最底部，与源设备以及前置放大器保持适
当的距离。比起把这样重的一个设备置于设备架的顶部，这种安放方法
同时也会更加稳固，因为置于顶部可能会导致重心过高，上重下轻。

请注意：在

CA-2200

功放的后面，交流电源线和设备接线
之间必须要保持足够的空隙。我们建议在你的功放后面保
持

8

英寸（

20

厘米）的空隙，这样，所有的接线都会有足
够的空间来伸展弯曲，而不会卷起来或者不适当的扭在
一块。

通风 你的 Classé 功率放大器在正常的工作过程中，会产生一定的热量。确保

在它的上部保留 6 英寸的空隙，两边各保留 3 英寸，以便热量通过空气
流通向外散发。CA-2200 功放的顶部和底部的通风口必须要保持畅通，
防止任何可能会减少通过设备气流的阻塞。切勿把此设备安放于柔软的
表面，这可能会限制气流（比如绒地毯）。

定制安装 本手册中附有安装图纸，以便符合特殊的安装要求和客户定制的设备家

具摆放要求（见设备尺寸部分）。一个可供选择的，专用设备架的安装
工具可以用于本产品。如想获得更加的信息，请联系 Classé 经销商。

序列号 你所购买的功率放大器上的序列号在设备的后面板上可以找到。请注意

本手册第三中提供的该序列号并记下，以备将来参考之用。

购买登记 找到序列号之后，现在就要填写登记卡了。请仔细填写你的购买事宜，

以便我们可以及时通知你一些更新信息以及其它一些你比较感兴趣的
东西。

阅读用户手册 请您花几分钟的时间浏览一下本手册，以便熟悉本产品。我们知道你

非常渴望插上每样东西，马上开始使用。不过，阅读本手册并按照上面
的建议去做，可以确保你会得到应该从本产品中获得的所有好。非常
感谢！

工作电压 CA-2200 型功率放大器的工厂设定电压（工厂内部）为 100V，120V，

230V，以及 240V 交流电压，这都是根据销售对象国家的电压规定而设

定电压值。（依据 CE 规定，230V 只适用于欧联国家）用户不可以改变
设定的电压。

功放后面板的标签上说明了你所在地区使用的正确交流电压值。如果功
放在错误电压值的情况下工作，可能会损坏该设备。

警告！ 用户不可以改变功放的电压设定值。设备内部没有需要用户

自行修理的零部件。如果遇到任何问题，请与专业的 Classé
服务维修中心取得联系。

如果功放上注明的交流电源电压不对，请联系你所在地区的当地授权经
销商或者销售商。

CA-2200 型功率放大器可以通过一根正常的 15 安培交流电源线轻松供
应电源。如果同时还有其它设备也是通过同一条交流电源线供电，那么
就要考虑一下它们之间额外的功率损耗了。

30

中文

CA-2200 型功率放大器中装有受保护电路，可以防止功放在极高或者极
低的危险电压情况下工作。

• 启动：启动时，交流电源电压必须是在正常值的大约 -15%

到 +10% 的范围之内，否则，功放就无法启动。例如，
一个电压为 120V 的设备要求的交流电源大小需在大约

95V√135V 之间，这样该设备才能启动。

• 工作中电压过高：如果在设备工作的过程中，交流电源电

压突然猛增大约 10% 或者更多，那么功放就会进入保护模
式，然后关机。备用的 LED 就会不断闪动，提示保护模式
已经启动。

• 工作中电压过低：如果在设备工作过程中，交流电源电压

突然下降 15% 或者更多，在这种情况下，功放仍会继续播
放（因为这不会对设备产生太大的损坏），但是值得注意的
是，在这种情况下，功放的播放效果会大打折扣，无法达
到正常水平。备用的 LED 会不断闪动，提示用户电压
过低。

预热／初始阶段 你购买的新 Classé 功率放大器将会马上发挥其出色的音色效果。不过，

你应该要对它进行预热，因为当它达到正常的工作温度以及其各零部件
的“初始”过程，就可以提高某些零部件的性能。我们得出的经验是，
在它工作的前 300 个小时内会发生最大的变化，因为当功放达到热平衡
时，电容器就会完全形成。在这个初始的预热阶段之后，你的设备将会
在以后的多年里保持一致出色的效果。

只有除了在这种情况下以外，如果设备安放好之后，很长一段时间都处
于闲置状态或者很久没有接上电源，这样就会又使它“冷”下来。根据
冷却的程度，用户应该要先进行一个简短的预热过程，然后功率放大器
才能达到最佳的音质效果。除非你的功放可以变得特别冰冷，之后的再
度热稳定不应进行太长。幸运地是，你绝对无需再次重复进行 300 个
小时的预热初始期。

阅读用户手册

请您花几分钟的时间浏览一下本手册，以便熟悉本产品。我们知道你非常渴望
插上每样东西，马上开始使用。不过，阅读本手册并按照上面的建议去做，
可以确保你会得到应该从本产品中获得的所有好。非常感谢！

设计特点

高度精确的电路设计 所有的 Classé 模拟放大进程都要以电路为基础，通过多年的持续发展，

该电路已经全面达到最佳化。

以出色的电路设计开始，经过多年至今，在一系列的各种应用过程中，
我们发现了许多细微的缺陷并加以改进，最后实现最好的效果。在这个
地方改变一下工作电压，或者在那个地方使用稍微不同的零件，这都可
以在立体的和完全出色的效果之间产生所有的差异。

这种水平的改进源自大量的经验，而不是那些随着潮流观念一掠而过的
人所能取得的。在 Classé 产品中无需对其声波效果的一致性进行测试（
因为它们都是基于类似的模拟进程），还有设备用户和分析师收到的关
于这些产品的同样优秀的评论。

广泛听觉测试 对于世界级的产品，应期望得到出色的测量效果，而 Classé 产品就做到

了。不过，经验告诉我们，仅仅是技术上的优秀并不足以在主观上保证
音乐效果。

出于这个原因，所有的 Classé 产品在开发过程中通过严格控制的听觉试
验都经过了反复的调试。我们的耳朵就是最好的实验工具，很好地弥补
了传统工程测试器材的不足之处。在产品电路的优化过程中，通过一个
又一个高质量的零件，根据主观感觉，我们得出了数以百计的改进
决定。

举一个例子，我们可以听一下几家不同公司生产的 6 个 0.1% 的同值薄
膜电阻器。标准的测试会显示它们在噪音、失真等等方面发出同样的结
果。但是几乎不变的是，在产品开发过程中，一种选择会在对产品性能
的主观反应中产生一些小小的改进。更少的时候，甚至单独这样一个变
化也能够导致令人惊讶的巨大改进。

加上那些各种各样的改进，数十种甚至数百种这类改进决定，这些改进
决定必须在产品投入生产之前做出，你会有显著的改进；事实上，所有
基于严格听觉测试的东西，我们都把它们视作立体工程的必要补充，这
可能是你正要从 Classé 产品中所希望得到的。

32

中文

超常使用寿命 采用高度精确的电力设计的另一个优点就是，经过多年后，我们在长期

使用中什么器件能发挥最好效果这方面累积了丰富的经验。

开始的时候，只使用最高质量的零部件，然后以一种无形的方式加以使
用，结果就是，促进了产品的老化实验以及实际的长期经验，我们能够
设计并生产出这类产品，这些产品能够经受住时间的考验，对此，我们
非常有信心。

我们有信心，你的新 Classé 产品将会为你带来多年的音乐享受，并且
不会出现任何问题的可靠性，就像我们以前向我们的客户推出的 Classé
产品。

耐用保护 最后，你的新 Classé 功放由各种各样的保护电路组成，它们都是用来保

护功放和扬声器，防止危险的故障发生。值得注意的是，这些保护电路
不会干扰或者限制功放的正常播放效果；而且，当遇到危险的情况时，
它们就会马上关闭功放。这些危险情况包括：

• 输出超载

• 削波

• 直流电平偏移

• 交流电源电压（超出正常电压范围）

• 工作温度过高

如果以上任何情况发生

（任何一种情况都可能会损坏你的功放和扬声

器）

，功放就会立即自行关闭。在这种情况下，LED 的指示器就会不断

闪动，直到故障被纠正，功放重新启动。如果故障只是出现在某一个声
道中，那么只有声道的 LED 指示器会变红并闪动；但是如果故障是与
声道无关（例如：交流电源电压），那么备用 LED 就会闪动。

33

中文

前面板

1 待机按钮和 LED 指示器

前面板上的备用按钮在它完全工作状态和“待机”模式之间会启动
功放，其中待机模式使功放处于“关闭”状态，经过任何支持的控
制选项（如：IR 输入，直流电触发器，CAN母线或者 RS-232）随
时准备响应系统发出的命令。

功放的当前状态，可以通过前面板上待机按钮的 LED 来查看。

LED 发出的颜色及对应的状态说明如下：

• 长亮 = 准备

• 问亮（开机初肘） = 初始化

• 不亮 + 声道 LED 长亮 = 操作中

• 闪亮（开机后） = 交流电源不足或超标

当机器处于

待机

状态时，功放机的增益级就会关闭。只有很小的电
源供应和控制电路仍然处于打开状态，相对来说，几乎没有什么功
率了。幸好，由于设备本身的输出级需要大量的电流，因此你的功
放机也很快就会达到预热效果，发挥最佳音色。

如果你长时不需要使用功放机，比如出去旅行休假的时候，我们建
议你断开功放机与交流电源的连接。在断开与电源连接之前，请先
确定功放机是处于待机状态。

同时，在暴风雨（电暴）的天气里，建议你最好断开所有与交流电
源连接的接线，还有所有值钱的电子产品，也应断电，因为附近任

34

中文

何地方的雷击都有可能会对交流电源产生巨大的冲击，而交流电源
就会很轻易地跳过简单的电源开关。电源冲击（电源可能会达到上
万伏）就可能会毁坏所有的电子产品，无论它的设计和保护性能有
多好，都会被毁。在剧烈的电暴情况下，最好的保护方法很简单，
就是断开电子产品与电源的连接。

2 选择按钮

在进行功放机单端输入或平衡输入的设定时，要使用到选择按钮（
它要和模式按钮一同使用）。另外，Classé 功放机是通过 CAN 母线
通讯或者触发器系统连接到一个 Classé 的前置功放机，在设定它的
各级数的打开顺序时，也要使用到选择按钮。

3 声道状态的 LED 指示器

你所购买的功放机的每个声道都有与其相对应的 LED 指示器。各
个互不相同的 LED 说明功放机所使用的声道，平衡 (XLR) 或者单
端 (RCA) 输入。

同时，当功放机出现问题的时候，这些指示器也可用来说明功放机
的故障情况。如果显示声道的指示器变成红色并不断闪动，就说明
与之对应的那一声道出了问题。如果所有的指示器都变成了红色并
闪动，这说明是系统出了故障，而不是单个声道的问题。

注意！ 如果你看到声道 LED 的指示器变红并不断闪动，那么请马上断

开功放与交流电源电压的连接，并检查所有的外部连接是否连接
妥当、安全可靠。如果故障不是立即显现出来，请与你所在地区

后面板

以下讲述的内容是当你购买的新设备在出了问题的时候，用来供你做参
考的。请参见下一章节（下一章节名称是

出厂设置

），关于把你所购买

的新功放机与音响系统组合的特别建议。

1 平衡 (XLR) 输入

平衡音频系统互连最初开发于专业的音频世界，用来保留极小扩音
器信号之间的极其微小的差别。多年以后，也就是现在，它们被一
些以性能为导向的消费公司所采用，比如 Classé 公司，用来保留你
的音乐中最优质音频性能之间的每一个细微差别。

从技术上来讲，平衡音频互连具有两大截然不同的优点：当信号从
一个设备传向另一个设备时，信号强度会增加两倍，加大了潜在的
信号，噪音比达到 6dB；同时它们在抑制噪音和干扰方面也做得相
当不错，没有它们，由于 (EMI) 电磁干扰或者 RFI（无线电频率干
扰），噪音和干扰可能就会在各设备之间出现。在我们如今无线通
讯发达的现代世界，在我们周围潜在的干扰性因素比以前更多，这
对我们的音乐和电影声道产生严重影响。

36

中文

出于这个原因，我们强烈建议你在我们的 Classé 组合音响设备之间
尽可能地使用平衡模拟互连系统。

这些平衡类型的母形输入连接器的引脚配置是：

引脚 1 ：信号地线
引脚 2：信号 +（同相输入）
引脚 3：信号 √（倒相输入）
连接器接地接线片：底盘接地

这些引脚配置都符合美国声频工程学会所采用的标准。

如果你正在使用一个带有 Classé 前置扩音器的 Classé 功放机，一切
都固定好了，只需要买一根标准的平衡互连接线，然后插入进去。
接着根据

出厂设置

一节中所述的方法设定并插在功放机上。

如果你使用的是另一个品牌的前置扩音器，那么就请参考平衡输出
前置扩音器的操作手册来检验输出连接器的引脚配置是与功放机相
配。如果不相配，那么使用经销商提供的接线，这样相关的输出引
脚就可以连接到对应的输入引脚上。

2 单端 (RCA) 输入

使用 RCA 连接器的单端接线时在消费电子产品中最常用的一种
模拟连接方式。每当小心实施、与高质量的互连接线一同使用的
时候，这种规格就能发挥极其优越的性能。Classé 已经作了最大努
力，确保你的功放的单端输入 (RCA) 尽可能完美。不过，这种连
接标准不会具有抗干扰的作用，而平衡互连接线具有这种功能，
因此我们的建议是尽可能多用平衡输入。

如果你为你的 Classé 功放机选择使用单端输入，那么你需要根据

出厂设置

一节中所述的方法对它们进行设定，然后再使用。

3 扬声器输出

在功放机的每个声道上面都有两套高质量的带有 5 条线路的接线
柱，以便“双边接线”。

实际上，双边接线就是在每个功放声道和与之相对应的扬声器之间
连接两套（两套一样的更好）扬声器接线。在很多情况下，在主观
上来讲，优点就是提高了扬声器的清晰程度，结果是能够同时为交
叉和驱动补充装置这两个分离的部分提供同样的、甚至是分离的
信号。

中文

37

(许多高质量的扬声器也会在喇叭上提供两套接线。一般，扬声器
上的其中一套接线用于部分喇叭的交叉网络，而这些交叉网络能够
为音响提供信号；另外一套接线用来连接部分渡线，而渡线又能够
为其它剩下的喇叭提供中音和高音频率。）

虽然 Classé 功放机上的接线柱只能使用裸线，但我们还是强烈建议
你使用优质的平接线片或者钩形接线片，卷在或者焊接在喇叭接线
端上。使用优质的连接器可以确保喇叭接线不会因裸线的磨损和氧
化而渐渐恶化。同时它也有助于防止较差接线的突然短路。

4 Classé CAN 母线控制接口

保存这些 RJ-45 型的连接器，是为了用于以后的控制和通讯。

5 红外线的输入和输出

你的 Classé 功放机上有两个八分之一英寸的微型孔，是用来支持红
外线遥控设置的，这在如今的世界里普遍存在。通过红外线可以在
操作和待机两个状态中转换功放机，不连续的指令是用于操作或者
待机的编码。这些编码可以用于遥控系统中的“宏命令”，以便在
一个规模更大的全套功放系统中更方便地控制功放机。

事实上，这种对“红外线输入和输出”的说明有点不恰当：实际上
用于这些插头上的输入是电，而不是红外线。这通过使用标准的红
外线接收器、信号分配放大器以及发射器（可以从经销商处得到）
可以获得信号的输入和输出，从而把红外线远距离的闪现信号变成
相应的电脉冲。这样做，比较大的好处就是能够轻易地从任何需要
的地方发出信号，还有就是固定电力连接的可靠性。

因为一个红外线信号分配系统，比如经销商为你而设计的分配系
统，通常都必须要控制多个产品，你的功放机包含红外线输入（用
于控制本产品）和红外线输出（为了越过其它产品的同类信号）两
种。这使你能够以“菊花链”的方式控制各个产品之间的接线。

功放机是用来响应 3-12 伏直流电之间的红外线命令，小型插头的
顶部，相对于插头轴杆来说，我们把它叫做“正极”。

5Vdc <100mA

中文

6 直流电触发器输入和输出

许多音频和视频前置扩音器都能为相关设备提供一个直流电控制电
压，用来激发期望的性能。你的 Classé 功放可以利用这些能力在操
作和待机状态之间自动转换，可能是和 A/V 前置放大器本身相呼
应的。

两个八分之一英寸的小型孔为功放机提供遥控开启功能（也就是，
在操作和待机两种状态之间转换）。这些小孔为从一个设备上传向
其它设备上的控制电压提供简单的通过功能，使你能够非常轻松地
以“菊花链”的方式控制一系列的功放系统。

遥控触发器将会通过大小为 3-12 伏的直流电压来操作，两端极性
如下图所示：

7 RS 232 控制接口

这个 DB-9 界面接口有两个用途：

• 给你的功放机下载新的操作软件（例如如果增加了新的

功能）

• 通过系统，外部控制功放机，比如：i-Command™，

AMX® 和 Crestron™

如果想要获取更多的信息，请与经销商取得联系，咨询家庭自动
操作系统方面的信息。

8 交流电源输入

在 CA-M400 型功放中使用了 IEC（国际电工委员会）标准的电源
线。把接线插入提供的高电流 IEC 插座，然后再插入合适的墙上
插座。

9 交流电源保险丝

你所购买的这款 Classé 功率放大器中装有一个交流电源保险丝，就
装在后面板位置。如果你怀疑里面的交流电源保险丝爆裂了，那么
先断开功放与交流电源的连接,然后参阅故障消部份。

切勿自行拆开功放机。此产品内部没有需要用户自己修理的
零部件。

5Vdc <100mA

39

中文

最后，如果一切仍然正常，请把功放机放回原处，小心重新连接扬
声器接线。检查扬声器接线的两端，看是否有短路。然后再次打开
功放机。如果功放机功能正常（也就是说保险丝没有烧坏），那么
为了保护功放机不受过大交流电源的冲击，原始保险丝可能就烧坏
了。如果保险丝再次烧坏，那么请与经销商取得联系，寻求帮助。

切勿自行拆开功放机。此产品内部没有需要用户自己修理的
零部件。

危险！ 具有潜在危险的电压和电流可能就存在于你的功率放大器设

备中，甚至可能当功放机与交流电源断开连接时也会存在这
样的危险。切勿拆开功放机盒子的任何一个部分。此播放机
中没有需要用户自己修理的零部件。本产品如果遇到任何问
题，需要维修，请联系专业的 Classé 经销商或者销售商。

中文

出厂设置

你所购买的 Classé 牌功放机安装、使用起来非常简便。为了安全装配这个
新设备，并让你更加方便地使用我们的产品，请遵照以下所述的步骤进行
操作。

重要： 功放机与交流电源的连接应是安装新功放机时的最后一步操作。

另外，在所有其它设备都已经打开并稳定好之后，最后再打开功
放机是一直以来通用的好办法。

相反，在关闭功放系统的时候，首先要关闭功放机，因为这样就
可以防止其它设备中的任何瞬变现象通过扬声器。

1 根据随机所附说明书，拆开设备的包装

在进行这一步的时候，请务必小心，因为本功放机重量很重。

2 安放功放机（请先阅读“拆包和安放”一节），然后连接交流电源。

安放的工作包括位置选定，要保证有足够的通风，还要留足空隙便于
功放机后面所有接线的摆放。完成这些步骤之后，把功放机直接连接
到交流电源上。切勿使用延长线，因为大多数的延长线都不适用于你
的功放机所需要的电流要求。

3 功放机设定

为了方便自己对功放机的操作，在设定功放机的时候，要用到选择按
钮和模式按钮。

声道设定

在

待机

状态，点击选择按钮，代表声道的 LED 灯亮，表示每个声道

当前的设定情况（平衡输入或者单端输入）。

其中一个代表声道的 LED 指示器会不断闪动，这表示你可以选择平
衡输入或者单端输入来播放节目。点击模式按钮来启动平衡输入模式
或者单端输入模式，这通过两个代表声道的 LED 其中一个亮灯指示所
确定的声道模式。

再次点击选择按钮选择下一声道，然后重复上面的过程，直到功放机
如你希望设定好声道。继续点击选择按钮，直到所有的 LED 灯灭，
设定完成。

确保你在设定你的功放机的时候，使用你将会在每一声道中使用的
输入连接类型。你可以安全地使用任何组合形式，你的系统所要求
的单端输入或者平衡输入连接。

41

中文

设定功放机的开启顺序

在一个包含多个 Classé 功放机的系统中，你可以把各个功放机命名

为 #1、#2、#3 等等。

当功放机通过

CAN

母线通讯或者触发系统连

接到

Classé

前置功放机，然后它们就会按照你所规定的顺序依次打
开，而不是一次性全部同时打开。（如果在你的家中，几个功率比
较大的功放机在同一时间全部打开有时可能就会对交流电源产生很
重的压力，这样可能就会造成电路短路，从而导致损坏）。

把一个特殊的功放机命名为 #x，例如：

• 把功放机设定为

待机状态

（显示待机状态的 LED

打开）；

• 按住模式按钮，直到所有显示声道的 LED 都点亮。当你

进入的时候，所有的 LED 就都会不断闪动，表示当前功
放机的“编号”（例如：两次表示 #2 功放机）；

• 如果你想改变当前功放机的编号设定，那么请再次按住

模式按钮，直到表示声道的 LED 都点亮了。

• 同时继续按住模式按钮，点击选择按钮“x”次（次数跟

希望打开的功放机编号的数字相同）；

• 放开模式按钮。功放机上表示声道的 LED 就会闪

动“x”次，表示你的选择已经确定。

4 前置功放机的连接

当功放机处于

待机状态

或者与交流电源断开连接状态时，

如第三步

所选的连接，使用适当的平衡输入或者单端输入连接，连接中要使
用优质的互连接线。

确保所有的接线都已连接完好，即使是钳子只有稍微的挤压 RCA
的外壳，也要重新插入，以使接线连接牢固。

5 扬声器的连接

连接功放机的外部接线端到扬声器，使用优质的扬声器接线。

功放机上的黑色 (√) 一端要连接在扬声器的黑色 (√) 一端，而功放
机上的红色 (+) 要连接在扬声器的红色 (+) 一端。接好后，在每个
功放机声道和其对应的扬声器之间一共连上四根导线：两根互相分
离的带有 +/√ 的导线，一根用于低音，另一根则用于中音和高音。
确保在导线的末端，红 (+) 和黑 (√) 接线端之间的接线不会缠绕在
一块。

确保所有的接线都已连接完好，不会轻易随便松动，但也不能连的
太紧。如果当扬声器的接线只有适当的松动，而不会随意移动，那
么接线就已连接好了。如果把它们连接的更紧的话，就不是很好
了，（连的太紧）甚至可能就会损坏接线的连接。

42

中文

6 再次检查各个接线间的连接

我们知道这一步听起来有点多余，但是很值得再花一到两分钟的时
间来再次检查一下，可能就可以所有的接线都已经安全、正确地连
接完好了。

7 打开系统中的其它设备，然后再打开你的功放机

建议你再打开音响系统的时候，最后再打开功放机，关闭的时候，
最先关闭功放机。这样做是为了在打开/关闭的时候防止其它设备
产生的瞬变现象损坏你的扬声器。

保养与维修

在清除功放机机盒上的灰尘的时候，请使用羽毛掸子或者无纤维屑的软
质抹布。在清除脏物和手指印的时候，我们建议使用软质抹布沾上异丙
醇（酒精）。首先用抹布沾上酒精，然后用抹布轻轻地揩拭功放机的表
面。切勿使用过量的酒精，否则酒精就可能会从抹布上掉下来，进入功
放机。

注意！ 在任何时候，都不可以直接在功放机上使用液体清洁剂，

直接使用液体可能会致使功放机内部电子零件的损坏。

43

中文

故障消除

一般来说，当你遇到任何需要维修的问题时，请你与我们的 Classé 经销
商取得联系，寻求他们的帮助；不过，在联系经销商之前，请你先检查
一下，看出的问题是否在下面提到过。如果是下面的问题，那么请先试
用一下我们给你提供的解决办法。如果下面所列的问题与你的功放机所
出的问题没有任何关系，那么请你联系我们的 Classé 经销商。

1 没有声音，显示声道的 LED 不亮。

• 功放机没有接上交流电源，或者交流电源出了问题（比如
电路断路器，保险丝等等）。

• 可能遇到熔断电流或短期停电，这可能需要重新设定内部
的微处理器。拔掉设备的电源连接 30 秒，然后再接上，
重新打开功放机。

• 交流电源的保险丝烧坏。见下面的

疑难解答

#4（或者联

系 Classé 经销商）。

• 提供的交流电源不在规定的电源范围之内。请核对设备后
面板上注明的电压规定。

2 没有声音，一个或者多个显示声道的 LED 变红并不断闪动。

• 你的保护电路可能已经启动了。断开功放机与交流电源的
连接，然后再断开所有的其它输入和输出。

• 接着试着重新打开功放机，只和交流电源连接。如果 LED
还是不断闪动，那么可能就是功放机本身有问题，你应该
要断开电源的连接，然后送到 Classé 经销商处进行维修。

• 如果打开没有任何问题，那么就关了它，重新只连接各个
输入。然后重新启动功放机。如果设备进入闪动保护模
式，那么可能就是功放机设备的上行数据流中的某个地方
出了问题，可能是直流电平偏移等。你的功放机在保护你
的扬声器（因为即使是很小的直流电也可能会在相对来说
很短的时间内损坏掉音响）。试用不同厂商生产的设备，
看问题是不是只出现在一个设备上，或者一直都有这个问
题（这可以说明前置功放机的一个问题）。带上相关的设
备，和经销商取得联系，向他们寻求帮助。

3 功放机总是关机

• 确保功放机有充足的通风空间，室内温度应该在 105 华氏
度（40 摄氏度）一下。

• 按照上面提到的疑难解答办法一一排查（可能是功放机进
入了保护模式）。

中文

4 交流电源保险丝烧坏。

对于交流电源保险丝烧坏，有一套特定的解决程序，因为这种情况
极少发生，一旦发生，就说明出了比较大的问题。请你按照顺序遵
守以下步骤来解决这个问题：

a. 断开功放机与交流电源的连接，还有输入接线和扬声器接

线的连接，然后移开设备后面板上的保险丝盖子。

b. 如果保险丝的确烧坏，那么请换上新的保险丝，一定要是

同一型号、同一额定功率的保险丝。

如果使用任何其它型
号的保险丝，尤其是额定值很大的保险丝，那么有可能会
导致功放的永久性损坏。

如果你自己不怎么会更换保险

丝，那么请与你的经销商取得联系，寻求帮助。

交流电压： 100/120 VAC
保险丝类型： MDA 延迟式
额定值： 10 A

交流电压： 230/240 VAC
保险丝类型： MDL 延迟式
额定值： 8 A

c. 更换保险丝、盖上保险丝盖子之后，重新连接功放和交流

电源，

并在没有重新连接输入或者扬声器接线的情况下，

打开机器。如果保险丝再次爆裂，断开功放机与交流电源
的连接，然后联系经销商，寻求帮助。

d. 如果看起来一切正常，那么请把功放放回

原处

，然后
小心重新连接输入接线并打开功放机。如果这时保险丝
烧坏（或者功放进入保护状态），那么你的前置功放机/
处理机可能遇到严重故障。请与你所在地区的经销商取得
联系。

e. 最后，如果一切仍然正常，请把功放机放回

原处

，小心重

新连接扬声器接线。检查扬声器接线的

两端

，看是否有短
路。然后再次打开功放机。如果功放机功能正常（也就是
说保险丝没有烧坏），那么为了保护功放机不受过大交流
电源的冲击，原始保险丝可能就烧坏了。如果保险丝再次
烧坏，那么请与经销商取得联系，寻求帮助。

5 显示待机状态的蓝色 LED 快速闪动，同时一个或者多个显示声道

LED 变红并不断闪动。

• 断开设备与交流电源的连接，重新设定功放机，等待几秒
钟，然后重新连接功放机到电源。如果这样还不能解决问
题，请和 Classé 经销商取得联系，寻求帮助。
