Introduction
As an American electronics innovator for
over fifteen years, Carver Corporation has
contributed some of the industry's most
impressive and remarkable audio
technologies. In fact, many features that are
now considered standard (surround sound
and advanced signal processing) had their
first successful consumer applications in
Carver products. Today, many of our
components are regarded as Classics , still
used by their original owners.
Our continuing goal is to provide
affordable products of exceptional quality,
aimed at reproducing sound with absolute
accuracy. We are best known for our separate
audio components (particularly high-
performance power amplifiers), therefore,
any integrated amplifier bearing the Carver
name has extremely high standards to meet.
Combining the latest in signal path
technology with the muscle of Carver
amplification, the CM-2002 stands high
above its class. The amplifier section has the
performance and the clarity of some of the
best separate designs. The preamplifier
section includes essential purist features to
impress both the CD and the Record
collector. It has a separate digital input with
integral D/A converter and the phono
section accepts either Moving Magnet or
Moving Coil cartridges.
The CM-2002 also features Carver's
exclusive Sonic Hologram processing for
lifelike sound field imaging. There are
connections which allow the addition of an
external processor or equalizer and another
connection for adding an external amplifier.
These features allow great flexibility when
upgrading your system to higher power or
surround sound.
Thank you for placing your confidence in
us. We know that your integrated amplifier
will provide you with many years of listening
enjoyment.

Location
Observe the following precautions when
choosing a location for the CM-ZOOZ:
• Do not expose the unit to rain or
moisture.
• Protect from prolonged exposure to
direct sunlight.
• Avoid exposure to extreme cold or dust.
• Protect from heat and allow adequate
ventilation. Place away from any direct
sources of heat such as heating vents and
radiators. Make sure that air is allowed to
circulate freely behind, beside and above
the unit. Excessive heat is a common
cause of component failure.
• Do not place heavy objects on top of the
CM-ZOOZ.
• Do not place any audio or VCR tapes or
computer disks near the CM-ZOOZ.They
may be erased by the magnetic fields of
the transformer.
• Avoid exposure to electrostatic discharge.
..
• If you ever accidently spill anything on
the CM-ZOOZ,unplug the power cord and
contact your dealer for service
information.
l
are
You can gently dust off the front panel
and chassis with a soft dry cloth. Try to rub
horizontally, following the grained finish of
the front panel. Take extra care when
cleaning the window, not to leave any
scratch marks.
If you have something stubborn to
remove, use a mild dish soap or detergent
sparingly applied to a soft cloth. Do not use
alcohol, ammonia, or other strong solvents.
onnections
• No special tools are required to set up
your system, just RCA patch cords and
the speaker wires.
• Make sure that all of your components
are OFF before making or undoing any
connections.
• Connections labeled out on the source
component connect to those on the
CM-ZOOZthat are labeled in . For
example, the output from a CD player
connects to the CM-ZOOZCD input.
• The CM-ZOOZTape 1 and Tape Z outputs
connect to the record inputs of your tape
decks.
• Make sure that you connect left to left and
right to right. For example, the left output
from your CD player should connect to .
the left input of the CM-ZOOZ.
• It will help if you tag and identify each
connection cord and speaker wire.
• Whenever possible, keep the power cords
away from the patch cords and speaker
wires. This will reduce the chance of
picking up any electrical interference.
• The CM-ZOOZhas some AC outlets on the
rear panel. These should only be used for
low power components such as CD
players and tape decks .
• You might consider buying a good
quality surge suppressor to protect your
system from power spikes and surges.
• Always turn on the CM-ZOOZafter all the
other components are on.
• When turning off your system, always
turn off the CM-ZOOZfirst. This
precaution will reduce any turn-on or
turn-off noises in the speakers.

Chapter 2 RearPanel connections
The following pages contain drawings of typical connections that you might make in your
installation. These drawings demonstrate how each of the inputs and outputs on the rear panel
of the CM-2002 are interconnected with other audio components and speakers.
Your particular installation may not use all of the connections shown, although, if you are
using the CM-2002 as the center of a fully-fledged audio system you will use many or most of
them.
The inputs and outputs on the CM-2002 are labeled to correspond to the most common audio
and video components in use today. It is perfectly acceptable to connect other components to
unused inputs or outputs, so long as they have line level signals. The phono input must only be
used for a turntable.
Input/ output levels
Input and output levels for audio equipment are usually divided into three categories:
1 Phono Level
This is a very low level signal
that comes from the cartridge
of your turntable. Because of
its extremely low voltage, the
CM-2002 has a special phono
input designed on y for
turntables. The phono circuit
provides extra gain to
increase the signal, as well as
RIAAre-equalization to
restore the flat frequency
response. This is altered by
the equalization used in
making phonograph
recordings. A Moving-Coil
cartridge has a much lower
output than a Moving-
Magnet type. The CM-2002
rear panel switch will
increase the gain when using
the Moving-Coil type.
o
2 LineLevel
This is the signal level that
comes out of almost all audio
components produced today,
except for power amplifiers,
turntables and microphones.
It ranges from several
hundred millivolts to several
volts (AC). Any line level
signal can be connected to
any of the line level inputs on
the CM-2002. For example, if
you have a DATtape deck,
but you don't have a second
cassette deck, you can
connect it to the TAPE2
input. A VCR can also be
connected to a Tape input for
playback and recording. A
LaserDisc player can be
connected to the Auxillary
input.
3 Speakerlevel
This is the signal level that
comes out of the speaker
output terminals on the
CM-2002. It can range from a
low level up to 30 volts (AC).
Some high-powered
amplifiers can reach voltage
levels approaching that
present on a household AC
outlet These connections
should only be made to a
speaker.

Turntable and Tape decks
..i
,
Any standard turntable with either a Moving-Magnet or Moving-Coil cartridge can be
connected to the phono inputs of the CM-2002. The turntable must have a phono-level output,
not line level. Make sure the CM-2002 is off before setting the cartridge selector switch.
Connect the ground wire of the turntable to the ground connector on the CM-2002 to reduce
any hum heard in the speakers.

SpeakerConnections
The CM-2002 output terminals are designed to accept
bare speaker wires.
1) Strip 1/2" of insulation off each wire and make sure to
carefully twist all the fine strands together. Even if
one strand is loose and touches the opposite terminal,
a short circuit will result.
2) Unscrew the CM-2002 terminals and insert the wire.
Tighten the connection down onto the wire

This will keep all the
speakers "in phase". For
example, if there is a
loud drum beat, all the
speaker cones will be
moving outwards at the
same time. If one speaker
is "out of phase" then its
speaker cone will move
inwards at this time.
This causes a sound
cancellation, resulting in
a bass reduction.

Speaker lacement
Eg Ja diStance
Since there are many different speaker designs available, you should closely follow the
recommendations of your speaker manufacturer, with the addition of the following points.
t
1. Adjust the toe-in so that they both
point in towards the listening chair.
2. To get the best results from the Sonic
Hologram circuit, the left speaker should be
set exactly the same distance away from your
listening position as the right speaker. While
this relationship is important in any stereo
system, it is more important when using the
Sonic Hologram. It might help to place a
coin as a marker, on the center of the chair.
Measure from this point to the center of each
speaker and adjust until they are the same
distance away.
3. Ideally, the speakers should be no closer
than two feet from the rear and side walls, in
order to reduce any reflections that might
upset the Sonic Hologram imaging. If your
speakers are closer than this, you can
experiment by adding sound deadening
material, such as curtains, on the walls to
reduce any unwanted reflections. For more
details of the Sonic Hologram, see page 19.

This is the main power switch to turn the CM-2002 on or off. When this is
pressed the standby light above it will turn on and your system will be ready to
play after a few seconds. You may hear the relays click on during this start-up
time.
This accepts a standard 1/4 inch stereo headphone plug. It does not shut of the
main speakers when the headphones are plugged in. Usethe Speaker-Mute
control if you want headphone-only listening.
Use this to temporarily turn off the sound to your speakers. It does not affect the
headphones or your recordings.
This control will boost or reduce the output level in the Bass frequency range.
Turning it fully clockwise will provide a boost of 8 dB @ 100 Hz.
Turning it fully counterclockwise will produce a reduction of 8 dB @ 100 Hz.
This control will boost or reduce the output level in the Treble frequency range.
Turning it fully clockwise will provide a boost of 8 dB @ 10 kHz.
Turning it fully counterclockwise will produce a reduction of 8 dB @ 10 kHz.
This is used to balance the output of your speakers. It is useful if you are sitting
closer to one speaker than the other.
Turn it clockwise to make the left speaker play quieter.
Turn it counterclockwise to make the right speaker quieter.
If you are listening with the Sonic Hologram engaged you should set the
balance to the center position.
This will improve the performance when listening at lower volume levels by
boosting both the Bass output and the Treble at the same time.
It provides a 6 dB boost at 100 Hz and a 2.5 dB boost at 10 kHz.
This allows you to select which sound source you would like to record onto
your Tape decks. Rotate this control until the desired source is selected and then
set your Tape decks to record. You can listen to something else at the same
time. See page 18 for some recording examples.
This will bypass the Tone controls and the Balance.
The signal path is shorter and this will improve the sound quality.

ON is by pushing the button in
again.

If the eM-2002 is ON and you use the
remote control power button to turn it OFF,
it will go into the standby mode. There will
be no power to the speakers and all the lights
will go out except for the standby light. The
eM-2002 will respond to the remote control
power button to turn it back on again.

This is because the meters are indicating the
ver ge power output. Momentary musical
peaks can drive the amplifier to its
maximum output for brief periods, faster
than the meter needles can respond.
The best way to tell whether the amplifier
is overloading is to listen. If the sound
becomes distorted on musical peaks at the
same time the meter needles are pegging ,
you have probably exhausted the eM-2002's
power reserves. If this occurs, you should
reduce the volume level.
A typical listening session would be as
follows:
1. Turn on vour Cl), Tape decks, etc.
2. Turn down the volume control and push
the front panel power button in.
3. Play your Cl), Tape, etc and adjust the
volume as desired.
4. When finished, you can use the remote
control to turn off the eM-2002, by
putting it into standby.
5. The Standby light will stay on, indicating
that it is ready to be turned on at any
time.
6. If you have finished listening for the day,
you should press the front panel power
switch to turn it off. This is a precaution
in case of power surges during the night.

The Record-out selector on the front panel
of the CM-2002 will allow you to select the
source you would like to record on either
tape deck. You can record something
different from that playing in your speakers.

to another Tape dubbing).
When you have selected a record source,
there will be an output from the CM-2002
TAPE lout and TAPE 2 out on the rear panel.
This is a straight copy of whichever source is
selected and it is unaffected by the Tone
control settings, the Sonic Hologram, Mute
or the Volume controls.
The Record-out selector will allow you to
record from Tape 1 to Tape 2 or from Tape 2
to Tape 1.
For example, if you want to record from
Tape 1 to Tape 2 :
1. Rotate the Record-out selector to the
position marked Tape lc-Z.

Appendix A Sonic Holography
Sonic Holography is a unique process
which enhances the three-dimensional
effects and realism of stereo sound.
To understand the benefits of this circuit,
we must first understand a problem in
obtaining accurate sound reproduction.
In a stereo system, both ears hear the output
from both speakers. The left ear hears sound
from the left speaker and from the right
speaker. To see the problem with this,
compare what happens when listening to a
live musical performance:
During a concert, each ear will receive
one direct sound arrival. For example, a
cymbal crashes, both ears will hear it and our
brain tells us accurately the position of the
musician.
In a stereo recording of the concert, this
cymbal crash will be heard from both
speakers. Our left ear will hear the left
speaker, which is fine, but it will also hear
the crash from the right speaker. The extra
arrival tends to confuse our accurate sense of
positioning, giving a general feeling that the
musician might be over there somewhere .
An example of this effect is if you use a
good pair of headphones. The stereo effect is
more pronounced because the left ear only
hears the left headphone, and the right ear
hears only the right headphone with no
extra arrivals.
:} .
\
To summarize:
1. A real musical event will create only two
direct sound arrivals one at the left ear and
one at the right.
rJ -
2. Stereo playback will give four arrivals as
both speakers are heard by each ear.
These second sound arrivals reduce our
naturally accurate sense of positioning, used
for listening pleasure and self preservation.
The Sonic Hologram circuit was designed
to cancel out the unwanted second arrivals.
The left ear will mainly hear the left speaker
and the right ear mainly hears the right
speaker.
This is accomplished by sending a
complex crosstalk signal from the left and
right speakers, in addition to the normal
program. These extra signals are virtually
identical to the unwanted second sound
arrivals but they are out-of-phase with them
and they cancel each other out.
The result is a more three-dimensional
and wider soundstage, where the positioning
clues are restored. In a way, the musicians
have been freed from the confines of the flat
plane between the speakers. You will perceive
them as playing forward or playing behind
the speakers or to one side or the other, not
just somewhere in between.
We recommend that you experiment
with its effect, remember that you are
listening for a more accurate sense of the
location of the different musicians.
As the Hologram works by phase
cancellation of the unwanted second sound
arrivals, accurate speaker positioning is
required to make sure that the left speaker is
the same distance away from you as the right
speaker. You must follow the speaker
placement on Page 13 to get the best results.
This is the same as any standard stereo
system only with more care taken to position
the speakers accurately.

Appendix B Connections
Interconnects Speakercables
• Choose reliable hook-up cables, also
called patch cords or RCA cables. There
are many different grades of cable
available and you might want to ask
your Carver dealer for advice. The main
thing is that they should be fully
shielded and as short as possible for the
job. Try to layout the system so that
most patch cords are less than six feet,
perhaps most will be three or four feet
long.
• The longer the distance from the amplifier
to the speakers, the thicker the speaker
wire should be.
• The thickness of speaker wire is specified
as a "gauge". The thicker the wire, the
smaller the gauge. For example, 16 gauge
is thicker than 18 gauge. Most systems
use 16, 14 or 12 gauge wire.
• The following table shows the minimum
recommend gauge for different lengths.
• Some patch cords can be a very tight fit
and there is usually a preferred method
of getting them off, some have to be
removed with a twisting action. Be
gentle or you may damage the jacks of
the preamp or your other components.
• Some special patch cords can only be
hooked up in one direction, these are
usually marked with arrows.
Length Gauge
up to 2S feet 16
up to 40 feet 14
up to 60 feet 12
• For video connections, use cords made
especially for video signals, otherwise
the picture quality may be degraded.
Video cables are specially designed to
match the video circuits electrical
characteristics.
• Use speaker cables which are marked in
some way to help you connect them up
correctly. Some have a black stripe or a
ridge on one of the cables, other types
have a silver strand or thread running
through.
• It is usual for the right patch cord plugs
to be red and the left connections to be
white, grey or black. Video connections
are usually yellow.
• You might start with standard speaker
wires and connection cords and then
upgrade them later when you want to
fine tune your system. Your dealer can
advise you on the different cables and
cords available.
