INTRODUCTION
WELCOME!
Luxman welcomes you to the growing num-
ber of discerning audiophiles who own and
operate Luxman Audio and Audio-Video
Products. We take great pride in the long
tradition of excellencein sonic quality that the
Luxman name represents. This manual has
been prepared to help you to maximize your
enjoyment of the outstanding performance
and features of your new Luxman C-03.
TheLuxman C-03stereo preamplifier, as the
control center of your sound reproduction
system, employs some of the most refined
and advanced technology available to
achieve iuxmen's constant quest for sonic
quality.
WHEN YOU OPEN THE BOX
Before any Luxman product leaves the factory it is
carefully inspected for physical imperfections as a
routine part of Luxman's systematic quality control.
This, along with full electrical testing, should insure
quality craftsmanship and performance. After you
have unpacked the unit, inspect it for any physical
damage. Save the shipping carton and all packing
materials, as they are essential to reduce to a mini-
mum the possibility of transportation damage, should
the product ever need to be shipped again. In the
unlikely event that damage has occurred, notify your
dealer immediately and request the name of the car-
rier so that a written claim to cover shipping damages
can be initiated.
THE RIGHT TO ANY CLAIM AGAINST A PUBLIC CAR-
RIER CAN BE FORFEITED IF THE CARRIER IS NOT
NOTIFIED PROMPTLY AND IFTHE SHIPPING CARTON
AND PACKING MATERIAL ARE NOT AVAILABLE FOR
INSPECTION. SAVE ALL PACKING MATERIALS UNTIL
THE CLAIM HAS BEEN SETTLED.
To realize the exceptional performance for
which thispreamplifier is capable,it is neces-
sary that all signal sources, power amplifiers
and speaker systems used with it are of the
highest sonic quality. We recommend
complementary Luxman components wher-
everpossible.
Please study this manual carefully and
become acquainted with all features, opera-
tion and capabilities of your new Luxman
C-03. Should you have any questions, or
desire information on other Luxman
products, please contact your local Luxman
dealer.
INSTALLATION AND PLACEMENT
Because some heat is generated by the C-03, adequ-
ate air circulation must be provided to maintain cool
operation. Leave adequate space around the
preamplifier (at least 3 inches on the top and 1 inch on
the sides and rear) for proper air circulation. Also, the
Luxman C-03 should not be completely enclosed with
other heat producing components. If the Luxman
C-03 is going to be mounted in an enclosed cabinet, it
is recommended that the back of the cabinet have
vents to allow air to circulate around the preamplifier.
With these considerations implemented, the Luxman
C-03 should provide exceptional performance in any
reasonable environment.
Of course, such normal considerations as protection
from excessive dust and moisture should always be
observed. The Luxman C-03 preamplifier has been
carefully designed with high quality components so
that long term undiminished performance may be
expected when it is operated in accordance with the
instructions provided .

BEFORE MAKING CONNECTIONS
It is always wise to ensure that all AC power cords of
the various components that you are interconnecting
are unplugged from the wall outlets during the hook-
up process. This will prevent any inadvertent damage
to your speakers or amplifiers from incorrect control
settings or connections.
BASIC OUTLINE
The C-03 is a pre-amplifier, and as such is the control
center of your sound reproduction system. However,
for a complete function stereo system, a power ampli-
fier to drive your speakers must be connected to the
C-03, and a record player, tape/OAT recorder, VCR,
tuner, etc. must be connected to the inputs of the
C-03. Thus, the connections of these components will
form the basis for your sound reproduction system.
CONNECTING A POWER AMPLIFIER
The C-03 is equipped with two sets of output jacks.
Using a set of pin plug cords, connect the output jacks
of the C-03 to the input jacks (INPUT) of your power
amplifier, taking care not to confuse the left and right
channels. (Use PRE-OUT A for normal stereo play-
back.) Using different pin plug cords for the left and
right channels facilitates easy checking of the unit
connections.
INTERCONNECTING LEADS (Patch Cords)
Be sure that left and right channel identification is cor-
rect when making interconnections. Most patch cords
are color coded with REOends for the right channel
and BLACK or WHITE ends for the left channel, to
make this job easier.
In addition, all jacks on the rear of the C-03 have red
centers for right channel, white for left channel and
yellow for each video jack.
CONNECTION OF AUDIO AND VIDEO TAPE DECKS
One of the common problems in connecting tape/
video decks is confusing the LINE IN and LINE OUT
connections to the pre-amplifier, resulting in no output
even in the SOURCEmodes. To prevent this, always
connect the LINE OUT jacks of the deck to the MONI
(monitor) input jacks of the pre-amplifier and connect
the LINE IN jacks of the deck to the RECOUT (record
out) jacks on the pre-amplifier.
CONNECTION OF VIDEO EQUIPMENT
Follow the connection diagram carefully when con-
necting video equipment to the C-03. In addition, be
sure to read the owner's manuals of such equipment
fully, to ensure proper operation.
It is recommended that only the highest quality TV
monitor, Hi-Fi VCR, LO, etc. be used to complement
the high performance standards of the Luxman C-03.
CONNECTING THE RECORD PLAYER (TURNTABLE)
In addition to the audio lead connections, be sure to
always connect the ground wire from the player to the
GNO terminal (item #20) on the C-03.
When making connections, follow the connection dia-
gram referring also to the descriptions for items #20
through #30 on page 6, 7.

POWER AND SOURCE SWITCHING
To prevent the possibility of excessive, sudden sound
levels, it is recommended that the volume control be
placed at a low level position each time the power
switch is turned on or when switching between
sources.
TAPE RECORDING OPERATIONS
To make a tape recording of any source, proceed as
follows:
(1) Depress the INPUT SELECTOR button for the
source you wish to record.
(2) Place the RECOUT Selector in source position.
(3) The source signal will now be fed to each of the
two tape recorders (tape/DAT-1 and tape/DAT-2)
(to all RECOUT Jacks), if connected.
Follow the recording instructions for the tape deck
in use.
(4) If you have a 3-head deck, you can monitor the
actual recording by depressing the tape/OAT but-
ton PLUS the TAPE MONITOR button (item #6).
The MONITOR position must also be selected on
your tape deck.
TAPE PLAYBACK
Playback from each of the two tape decks can be
heard by depressing the corresponding tape/OAT but-
ton, PLUS the TAPE MONITOR button (item #6).
NOTE: The Straight In button (item #8) must be in
the OFF (out) position for each of the above
operations.
TAPE DUBBING (Audio)
Tape copies (or dubs) can be made between the 2
decks as follows:
(1) If you wish to copy from deck 2 to deck 1 , place
the RECOUT selector (item # 12) in the TAPE 2 ~
1 position.
(2) In like manner, if you wish to copy from deck 1 to
deck 2, set the REC OUT Selector accordingly
(1 ~ 2 position).
(3) If the copy deck is a 3-head machines, the actual
recording can be monitored by depressing the
TAPE MONITOR button (item #6) PLUS the tape/
OAT button (item #7) to desired TAPE-1 or -2
position.
(4) You may make dubs while simultaneously listen-
ing to any source selected by the INPUT
SELECTOR (item #14). Simply place the TAPE
MONITOR button (item #6) in the ON position
during the dubbing operation.
OAT (Digital Audio Tape) DECKS
When using the analog (audio) inputs and outputs of
such machines, you would connect them and use
them with the C-03 in the same manner as you would
for any audio tape deck.
NOTE: The C-03 has not digital input jack.
VIDEO PLAYBACK
Both audio and video playback from the connected
AN systems can be selected by depressing the
VIDEO-1 or VIDEO 2 button on the INPUT SELECTOR.
VIDEO TAPE RECORDING AND DUBBING
Both the audio sound tracks and video signals from
any AN source can be recorded by a video cassette
recorder (VCR)through the C-03.
To record a laser disc (LD), a TV stereo tuner or a VCR
connected to the VIDEO-2 inputs, proceed as follows:
(1) Place the RECOUT Selector in source position.
(2) Depress the VIDEO-2 INPUT SELECTOR button to
the "ON" position.
(3) The AN signals will now be fed to the VCR con-
nected to the VIDEO-1 jacks. Follow the recording
instructions for the VCR in use, being sure to set
its input selector to "EXTERNAL" position.
(4) For Dubbing, place the RECOUT selector in video
2 ~ 1 position.

TV OPERATIONS
You can watch and/or record off-the-air (or cable) TV
programs with high quality sound, using a HI-FI VCR.
With a video monitor or TV receiver connected
according to the CONNECTION DIAGRAM, page 8 pro-
ceed as follows:
(1) Set the INPUT SELECTOR of the HI-FI VCR, con-
nected to the VIDEO-1 inputs, to the TV or TUNER
position.
(2) Depress the VIDEO-1 INPUT Selector button on
the C-03.
(3) You can now view any channel selected by the HI-
FI VCR's tuner.
(4) A recording of the selected TV program can also
be made, while watching and listening to high
quality sound, by placing the VCR in the RECORD
mode.
If you have a TV monitor with stereo audio outputs,
these may be connected to the VIDEO-2 jacks for inde-
pendent TV operation with high quality stereo sound.
Proceed as follows:
(1) Turn the power OFF to the VCR connected to the
VIDEO-1 jacks on the C-03.
(2) Place the INPUT SELECTOR of the C-03 in the
VIDEO-2 position.
(3) Set the INPUT SELECTOR of the TV to the TV posi-
tion and tune desired channels.
NOTE: Be sure to consult the owner's manuals of the
VCR, TV monitor and other AN units for spe-
cific operational details.

CARE AND MAINTENANCE
CLEANING
The durable finish of the knobs and heavy aluminum
front panel will last indefinitely with proper care and
cleaning. Never use scouring pads, steel wool, scour-
ing powders, or harsh chemical agents, such as lye
solution. These will mar the finish. Clean with a soft,
lint-free cloth or cotton swab slightly dampened with a
mild solution of detergent and water.
REPACKING FOR SHIPMENT
Should it become necessary to ship your C-03 for any
reason, use the original packing materials. If these are
no longer available, be sure that adequate materials,
at least equivalent to the original, are used.
