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 ﬁ ll 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 CP-700 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 preampli–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 ﬁ nal performance of

the system.

ENGLISH

Unpacking and Placement

unpacking

your preampliﬁ er

Carefully unpack your preampli–er 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 preampli–er, it is best to place the CP-700 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 preampli–er 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 CP-700. We suggest leaving eight inches (20

cm) of free space behind your preampli–er to allow all cables suf–cient

room to bend without crimping or undue strain.

Classé recommends that the unit not be placed directly on the top surface of a

power ampli–er (or any other heat source).

ventilation

Your Classé preampli–er generates a certain amount of heat in the course of

normal operation. Be sure to allow three 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 air—ow (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

Dimensions). An optional, purpose-designed Dimensions

rack mount kit is available for this product. Contact your Classé dealer for more

information.

serial number

The serial number for your preampli–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.

7

ENGLISH

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 CP-700 preampli–er is set at the factory 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.

Make sure that the label on the rear panel of your preampli–er indicates the

correct AC operating voltage for your location. Attempting to operate your

preampli–er at an incorrect voltage may damage the unit.

Warning: The voltage setting of your preampliﬁ er 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 preampli–er is incorrect, please

contact your local, authorized Classé dealer or distributor.

The CP-700 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.

The CP-700 includes protection circuitry that will prevent the preampli–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 preampli–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 preampli–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 preampli–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.

ENGLISH

warm up/break-in period

Your new Classé preampli–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 preampli–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 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 preampli–er»s sound

quality is at its best. Unless your preampli–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 preampli–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 .

ENGLISH

Special Design Features

ﬂ exible graphic

user interface

The LCD touchscreen on the front panel of your new component supports an

extremely —exible and versatile graphic user interface (GUI) while maintaining

a clean, uncluttered appearance. The CP-700 provides a range of controls

that might otherwise require dozens of buttons and knobs on the front panel.

Despite this power and —exibility, it remains simple to operate in day-to-day use.

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 CP-700, 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

The volume control on your new Classé preampli–er is controlled by

sophisticated software that allows you to –ne-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 –ne control once you are close to the

≈perfect∆ volume. Of course, these characteristics are in con—ict 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.

The volume control system on your CP-700 solves this problem by responding

differently based on the speci–c 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 –nd intuitive

and a real pleasure to use. However, if you feel you would like to –ne-tune its

performance further in order to suit your particular preference, you may easily

do so.

highly reﬁ ned

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 these products receive from owners and reviewers

alike.

10

ENGLISH

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% tolerance –lm 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 –nalized 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 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 long-

term 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 preampli–er will give you many years of

trouble-free reliability and musical enjoyment, just as previous Classé products

have given their owners.

robust, isolated

power supplies

The CP-700 employs an outboard power supply to provide the ultimate in

performance. This unit includes a massive 135 VA toroidal transformer with

–ve secondary windings to provide maximum isolation for both the positive

and negative voltages required by each channel, as well as the voltage used by the

control circuitry within the preampli–er itself.

This design approach ensures that the preampli–er itself sees only the pure,

highly-regulated DC power it needs for handling the music signals, while the

high-voltage AC mains is kept safely away from your music. In short, it creates

an ideal environment in which the re–ned circuitry of the CP-700 can operate

to its full potential in service of your musical enjoyment.

If you are planning not to use the preampli–er 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 preampli–er is turned off 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 electronic equipment, no matter how

well designed and protected. The best protection in the case of severe

electrical storms is simply to remove the electronics from any connection

with the power grid.

on the right side of the front panel of the CP-700 is used

to control the volume of the system.

The 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.

5 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.

Classé has gone to extraordinary effort to ensure that the single-ended

(RCA) outputs of your preampli–er 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 outputs whenever possible.

If you are not using balanced analog interconnection, then connect these

single-ended outputs to your preampli–er using high-quality shielded

RCA-terminated cables. Your Classé dealer can advise you on the selection

of cables suitable for your system.

6 Balanced (XLR) main outputs

The CP-700 supports two pairs of high quality XLR outputs to provide

balanced stereo analog signal to your power ampli–er(s). In most cases,

you will connect one pair only to corresponding balanced inputs on your

power ampli–er, using shielded high-quality balanced interconnects. If

you choose to biamplify your speakers, you may need to use both outputs.

Your Classé dealer can provide assistance in selecting appropriate balanced

cables for your system, as well as advice on the potential bene–ts of

biampli–cation in your particular situation.

ENGLISH

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.

For this reason, we strongly recommend using balanced analog

interconnects between your Classé components wherever possible,

especially if you plan to use long interconnect cables between your

preampli–er and the power ampli–er(s) in order to minimize the length of

the speaker wires.

The pin assignments of these XLR output 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 preampli–er with a Classé power ampli–er,

you»re all set – just take standard balanced interconnect cables and plug

them in.

If you are using another brand of power ampli–er, please refer to the

operating manual of your ampli–er to verify that the pin assignments of

its input connectors correspond to those of the CP-700. If not, have your

dealer wire the cables so that the appropriate output pin connects to the

equivalent input pin.

7 RS-232 Control Port

This

DB-9

connector has two purposes:

• downloading new operating software into your preampli–er

(should new features ever be added, for example)

• external control of your preampli–er by control systems such as

the signals anywhere they might need to go and the reliability of a solid

electrical connection.

Two 1/8th-inch mini mono-jacks provide individually controllable DC

trigger outputs which can be used for any of a number of purposes, as

described in

The Menu System

. For example, your dealer can program

Trigger Out1

to toggle your Classé power ampli–er between operate and

standby with your CP-700.

The 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 source

up to 100mA of current.

11 Ground terminal

The ground terminal on your preampli–er 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.
