the dealer.
2.Are the shorting links on the dbx input/
output terminals on the rear panel in
place? (Note: if you have the optional
dbx* noise reduction unit and wish to use
it right at the beginning, this step does
not apply.)
3.Make sure the POWER switch @ is OFF.
4.Plug the power cord into an AC line
socket.
5 Using the pin cord supplied, connect the
Right) and Lleft) OUTPUT terminals

System Connections
Rear Connection Panel
Power Cord
This power cord is equipped witha plug to
connect to an AC power outlet.
External dbx terminals
These eight pin-sockets are used when the
optional RX-8 dbx noise reduction unit is
used. The RX-8 Owner’s Manual has full
instruction for connection to these termi-
nals. If an add-on dbx unit is not being used,
the shorting links supplied must be left in
place.
OUTPUT
Use these OUTPUT pin-sockets to connect
the output from your C-3 to your amplifier,
receiver or other equipment.
IN/OUT (DIN)
lf the equipment you are using with your
C-3 is only equipped with DIN sockets, you
may interconnect it using this socket. If
there is a choice, however, it is preferable
to use the pin-sockets. Do not use both the
pin-sockets and the DIN socket at the same
time.
LINE IN
These are the terminals where signals enter
the C-3 from other equipment such as your
amplifier or mixer. Signals from microphones
and directly from record players are too low
in level and cannot be fed into these termi-
nals. (Note: Signals directly from record
players cannot be used even into the more
sensitive MIC input as they are not “flat”
signals and require special equalizing
circuits.)
CONTROL SIGNAL
This is a special socket used for feeding a
control signal to an auxiliary dbx noise
reduction unit.
REMOTE CONTROL RC-90
The optional TEAC RC-90 REMOTE CON-
TROL UNIT can be connected to this con-
nector to provide remote control of the
C-3 from up to about 15’ away.

Stereo Playback
The procedures for stereo playback have
been detailed on page 1. Note that during
playback through an amplifier the OUTPUT
contro! should be set at about position “8”
and the volume control on the amplifier
used to adjust the level. When listening over
headphones, the OUTPUT contro! can be
used to adjust the level.
Stereo Recording
1 Press the POWER switch to switch on
the deck.
2 Open the cassette holder using the
EJECT button and insert the cassette
you want to record on.
3 Set the BIAS and EQ switches according
to the tape being used and the DOLBY
NR switch to ON if you want to make a
Dolby noise reduction recording.
Make sure that the BIAS/REC CALIB-
RATION button is in the PRE-SET
(11 ) position unless you have already
made the necessary adjustments required
to use this facility.
Press the RECORD and PAUSE buttons.
This will enable you to adjust the record-
ing level without actually recording on
the tape.
5 Use a signal from a tuner or amplifier
(plugged into the LINE IN inputs) or
from microphones plugged into the MIC
jacks and adjust the recording !evel using
the RECORD controls.
§ From a fully counterclockwise position,
gradually turn up the RECORD level
controls until the loudest sound to be
recorded just makes the meter indica-
tion reach the 0 dB point.
7 When everything is set up and ready to
go, set the tape in motion by pressing
the play ( > ) button.
8 When you want to stop recording, press
the STOP button. If you want to con-
tinue recording but want to pause, use
the PAUSE button instead. In this case
the record function will not be deacti-
vated and recording will resume when
the play ( » ) button is pressed again.
>
Erasing
A previously recorded tape can be erased on
the deck by recording the entire tape with
the MIC and LINE controls set to 0.
Setting the Recording Level
Setting the recording level correctly is
essential if you want to make top quality
recordings. If the level is too low the re-
cording will be unnecessarily noisy. If the
level is set too high, the recording will be
unnecessarily distorted. Generally speaking
the recording level should be set so that the
loudest signals to be recorded make the
meters indicate OdB BUT NOT MORE.
if the meters peak over the 0 dB point, the
RECORD level controls should be turned
down a little. With a little time and practice
you will be able to select that critical re-
cording level that gives you the best hi-fi
recordings. The type and condition of the
tape, as well as the type of music source
you are recording also affects the optimum
settings of the record level.

dB
PEAK LEVEL
LEFT RECORD RIGHT OUTPUT
Recording with Microphones
One microphone can be connected to the
L/MONO jack for monaural recording.
The signal will be automatically fed to both
channels (L and R). If both RECORD level
controls are set the same, the sound will be
“centered’’ between the channels. By raising
either level control, the sound “‘image’’ can
be made to move toward the higher level
channel. This is true also when using two
microphones for stereo recording.
Live recordings may have much wider
dynamic range than records or FM stations,
so be sure to watch the peak level meters to
make sure the input signal doesn’t exceed
0 dB and saturate your tape. To achieve
good mic recordings requires practice and
experience and is usually much more
difficult to do than normal copying of
records or FM stations.
BIAS/REC Calibration
Fm
wear
Before attempting any adjustment, be sure
to clean the heads, tape guides, rollers etc.
and demagnetize the heads and all metal
parts in the tape path.
e Adjustments should be done in the follow-
ing order: A) BIAS coarse adjustment,
B) REC LEVEL coarse adjustment, C)
BIAS fine adjustment, D) REC LEVEL
fine adjustment.
e You will need a test oscillator such as the
TEAC T0-8.
e Before beginning the adjustments, the con-
trols and switches should be set as indi-
cated.

4. Set the TIMER switch on the C-3 to
REC.
When the selected time arrives, power will
be applied to the C-3 and recording will
begin. When the tape reaches the end the
pinch roller will be released, the heads will
be lowered and the capstan motor will
stop. Power will still be connected to the
deck, however, and the control panel will
be inoperative. None of the buttons will
have any effect until the TIMER switch is
turned to OUT. Check that the cassette you
wish to récord on has its record protection
tabs in place otherwise the C-3 will go into
the play mode.
Timer Controlled Play Operation
1. Check that the C-3 is correctly con-
nected to the amplifier for normal
playback operation.
2. Connect the C-3 and amplifier to a clock
timer as for timer controlled recording
(above).
3. Make all preparations as for normal
playback, but do not set the tape in
motion.
4. Set the TIMER switch on the C-3 to
PLAY.
When the selected time arrives, power will
be applied and the C-3 will begin to play.
When the tape reaches the end the pinch
roller will be released, the heads lowered
and the capstan motor stopped. The control
panel will be inoperative and no button will
have any effect until the TIMER switch has
been set to OUT.
Over Dubbing (Punch in Recording)
During playback, you can go directly from
playback
mode
to
record
mode
by
holding
in the RECORD button and pressing the
play (> ) button at the same time. The
deck will begin recording from that location
while the tape continues to run. This opera-
tion is called “punch in” recording or
“running splice’. It allows you to record
over or correct a recorded section of the
tape without stopping the tape first and
then selecting record mode.

Record Muting
The capability of creating clear unrecorded
(erased) portions on a tape during recording
is a real advantage in many recording
situations. For instance, you may want to
eliminate undesired portions of an FM
broadcast that you are recording, such as
commercials, station breaks, or announce-
ments. You may want to record a complete
program with controlled spacing between
songs that can be filled in later with your
own choice of material. You may just want
a short period of silence between each song.
These erased portions on a tape could, of
course, be created using a deck which
doesn't have the record muting capability of
the TEAC C-3, but the operation would
be cumbersome and require several extra
steps which increases the chances for errors.
The TEAC C-3 makes the same operation
smooth and simple.

Three Head System
Three head system means that you can re-
cord on the tape and monitor from it at the
same time (see illustration). Conventional
combination record/replay heads permit
only recording or replay. With the three
head system you can check the quality of
your recordings as you make them.
Rack Mounting
Handles can be mounted or removed as
illustrated in the diagram. The black plastic
covers on the handles can be removed to
give access through holes for easier mount-
ing in EIA standard 19 inch racks.

REC MUTE
No signal interval
Signal on the tape'/\/\/\/ AVA A \\A AVA
During recording when you want the erased
space to begin just depress the REC MUTE
pushbutton. The tape movement continues
and the tape is erased until the PAUSE push-
button is depressed, which stops the tape
and puts the deck in the REC/PAUSE mode.
When you want to begin recording the next
selection just press the » (play) pushbutton
and normal recording will resume. You can
also go directly from record muting opera-
tion to record mode by pushing the > (play)
pushbutton instead of PAUSE. The RE-
CORD, REC MUTE, and PAUSE indicator
lamps will light to indicate the mode of
operation.
Note: You cannot go directly from record
pause mode to record muting mode. You
must first go to record mode, then to record
muting mode.

Maintenance
Access to the Heads
The cassette holder door cover can be re-
moved by lifting up on the cover (as shown
in the figure) to facilitate cleaning and
maintenance of the heads and tape move-
ment path. When the cover is removed, the
cassette holder door can be closed by push-
ing in on it.
Cleaning of the Heads and Tape Path
The oxide coating from a magnetic tape
sheds off the tape as it passes over the
heads, pinch roller, capstan shaft and tape
guides. After a period of time, the build-up
of the oxide and other dirt forms a coating
on these parts which will result in a loss of
frequency response and output from the
heads as well as drop-outs in the signal from
the tape. The oxide on the pinch rollers and
capstan shaft may even cause minute
changes in tape speed and loss of smooth-
ness of tape movement. This will result in
increased wow and flutter and a decrease in
sound quality. To prevent these problems,
regular cleaning at intervals of about 8 hours
of deck usage is recommended.

Cleaning Procedure
1. Remove the cassette holder door cover.
2. Press the » (play) button to engage the
pinch rollers and raise the heads.
3. Use a cotton swab or cleaning stick
moistened in rubber cleaner (Fluid B in
the TEAC TZ-261 Kit or equivalent) to
clean the pinch rollers and capstan
shaft. Use care not to get swab caught
between pinch roller and capstan shaft.
4. Depress STOP button to separate pinch
roller and capstan shaft and lower the
heads.
5. Use a cotton swab moistened in the
Head Cleaner (Fluid A in the TEAC
TZ-261 Kit or equivalent) to clean the
heads and metal parts in the tape path.
Demagnetization Procedure
1. Remove the cassette holder door cover.
2. Turn off power to the deck.
3. Turn on the head demagnetizer (eraser)
and bring the tip of it close to the heads.
Move the tip up and down across all the
heads and other metal parts in the tape
path.
4. Slowly withdraw the demagnetizer to
about 12 inches away from the head
area,
5. Turn off the demagnetizer.
Be sure to keep all recorded tapes away
from the demagnetizer during demagnetiz-
ing.
