Playback And Recording - Teac C-3 Owner's Manual

Playback and Recording
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.

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
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.
