Teac W-550R - Troubleshooting; Dolby Hx Pro

2. Press the SYNC REV button (the
corresponding indicator will light).
3. Press either of DUB START buttons
(HIGH or NORMAL).
4. The tapes in TAPE | and Il travel as
illustrated in the chart “Synchro Re-
verse Dubbing Operation’ on page 8.
Notes:
elf tapes with different lengths are used,
the blank section will be increased. To
prevent this, use tapes with the same
length as far as possible.
e During high-speed dubbing with the
SYNC REV button engaged, when either
deck stops at the end of tape, the other
deck performs normal-speed running
(playback or recording) till the end of
tape, at which point both decks are
reversed and high-speed dubbing restarts.
Manuel editing with REC MUTE
and PAUSE
During normal-speed dubbing, you can edit
the dubbed tape as required using the REC
MUTE and PAUSE buttons. For example,
you can record only the required tunes on
TAPE | to TAPE II bypassing the unwanted
tunes.
e During normal-speed dubbing, when the
PAUSE button is pressed, TAPE I! enters
the record-pause mode while TAPE | con-
tinues playback. While listening the TAPE
| sound, when the portion you want to
dub is reached, press the PAUSE button
again to restart recording on TAPE II:
e During normal-speed dubbing, when the
REC MUTE button is pressed, TAPE 1!
enters the record muting operation as in
normal ‘recording. To restart recording on
TAPE II, press the PAUSE button.
CAUTION:
Recording pre-recorded tapes, records,
or other published or broadcast material
may infringe copyright laws. Check be-
fore recording.
Timer-Controlled Operation
(Fig. 6)
By using the W-550R with an audio timer,
tapes can be recorded or played back at
any preset time. If tapes are loaded in both
decks, you can also start continuous play-
back in this way.
Timer Recording (TAPE 11 only)
Recording a broadcasting program:
1, Connect the deck and stereo system to a
commercially available audio timer as
shown in the diagram.
2. Set the power switches of all compo-
nents to ON.
. Load the recordable cassette in TAPE II.
Set the REVERSE MODE switch to the
required position. (Refer to ‘Tape
Travel Depending on Setting of RE-
VERSE MODE Switch” on page 6.)
5. Set the TIMER switch to the REC po-
sition.
6. Tune to the broadcasting station to be
recorded.
7. Press PAUSE then RECORD to set the
deck to the record-pause mode.
8. Adjust the recording level with the RE-
CORD control as in normal recording.
9. Set the DOLBY NR switch as desired.
10. Set the tape running direction to start
recording using the< or button of
TAPE Il.
11. Set the audio timer to the required start
(power on) and stop (power off) times.
When this setting is completed, the
power to all components will be switch-
ed off.
When the preset start time is reached, power
will be supplied and recording will start
automatically.
Pwo
Timer Playback
1. Connect the deck and stereo system to
a commercially available audio timer as
shown in the diagram.
2. Set the power switches of all com-
ponents to ON.
3. Load pre-recorded cassette(s) in TAPE
1 or Il (or both).
4, Set the REVERSE MODE switch to the
required position. (Refer to “Tape
Travel Depending on Setting of RE-
VERSE MODE Switch’ on page 6.)
5. Set the TIMER switch to the PLAY
Position.
Set the DOLBY NR switch as desired.
Set the tape running direction to
start playback using the <or > button.
8. Set the audio timer to the required
start (power on) and stop (power off)
times. When this setting is completed,
the power to all components will be
switched off.
When the preset start time is reached,
power will be supplied and playback will
start automatically.
Notes:
e The tape running direction just before the
power is turned off will be maintained
when the power -is turned on again.
Remember this when setting for timer
controlled operation.
eWhen cassettes are loaded in both decks,
TAPE | will start playback because it has
priority.
eWhen cassettes are loaded in both decks
with the REVERSE MODE switch set
to CONT PLAY position, the tape in
SP
a aoe
TAPE Il will always start playback in the
forward direction in continuous play.
eBe sure to set the TIMER switch to the
OUT position after timer operation is
completed.
Maintenance (Fig. 5)
The heads and tape path should be cleaned
and demagnetized periodically.
Cleaning Tape Path
eApply head cleaning fluid* to special
cotton swabs or a soft cloth, and lightly
tub the heads, capstans and all metal
parts in the tape path.
e Also clean the pinch rollers using rubber
cleaning fluid*.
*Both are available in TEAC HC-1 and
RC-1 in the U.S.A. or TEAC TZ-261
Tape Recorder Cleaning Kit in other
areas.
Demagnetizing Heads
Be sure that the power is off, then demag-
netize the heads using a TEAC E-3 demag-
netizer or equivalent. For details of its
use, read its instructions.
Troubleshooting
Basic troubleshooting of a cassette tape
deck is similar to troubleshooting any other
electrical or electronic equipment. Always
check the most obvious possible causes first.
To give you a few ideas of what to look for,
check the following:
e No power: Is the power cord connected?
e Tape begins running when power is turned
on: Is the TIMER function on?
eNo audio output: Are all connections
properly made?
e Degraded sound quality: Are the heads
dirty or magnetized? Are you using
good quality tape? Is the proper NR
System selected?
e Unable to select record mode: Are the
record protection tabs on the tape in
place?
DOLBY HX PRO
Dolby HX Pro is an “active bias” technique
that can improve the quality of audio tape
recordings. High-level high frequencies can
be recorded more accurately, without
sacrificing signal-to-noise ratio, while such
side effects of tape saturation as distortion
are reduced.
What Is Bias?
Bias is a very high-frequency signal generat-
ed within a tape deck and recorded on the
tape simultaneously with the program
