point in the recording whereyou want to enter a blank

TO insert a blank section of tape more than five seconds

return to the REC/PAUSE standby mode immediately
after the button is released. To continue recording, press
the forward or reverse play button @ to release

blank sections of sufficient
sensingsystems(such asthe AMCS)that operateby
detecting the blank sectionsbetween songs.
The Dolby Noise Reduction Systems
There are three types of Dolby noise reduction systems:
Dolby A, Dolby B and Dolby C NR. Dolby A NR is used
only in professionalapplications. Dolby B NR isthe system
that most. cassette tape decks use to reduce the back-
ground tape noisethat is inherent in all cassette tapes.
Recently, Dolby Laboratories developed an even more
effective noise reduction system, Dolby C NR, in
response to the demandfor increasinglybetter sound
quality from cassette tapes.
All three Dolby noisereduction systems operateby boost-
ing highrange signals duringrecording that fall belowa
certain input level. That's because tapehissis most
prominent during quiet, highend portions Ofa recording.
Thesesamesignalsarethen reducedbackto their original
strengthduringplayback therebyreducing thebackground
noiseby the sameamount. In order to operateonly when
necessary, t he Dolby systemhasa varyingeffect depending
on the input leveland frequencyof the materialbeing
recorded. Dolby C NR can reduce background noiseby as
much as 20 dB (above 5 kHz). Since the midrange tends
to sound unnaturally strong when noise is suppressed only
in the high range,Dolby C NR extendsits noisereduction
effect down to a lower frequency rangethan Dolby B NR.
In addition to its noise reduction function, Dolby C NR
has an antisaturation neuork that lowers high input levels
before recording them and returns the signalsto their
original strengthduringplayback.Thisraises thehigh

The maximum output level of cassette tapes is increased
by more than 4 dB at 10 kHz by this system.
Using the Filter Button
When recording an FM broadcast using Dolby N R, the
19 kHz pilot signal and the 38 kHz subcarrier signal
included in FM stereo broadcast
Dolby circuitry to malfunction.
occurring, the TA-R77 is equipped with a filter button
so that the Dolby circuitry can be operated through a
filter. Therefore the fiiter button @ should be ON when
recording an FM broadcast using Dolby NR and OFF at
all other times.
Using the AMCS Function
The AMCS (Automatic Music Control System) automatically
locates the beginning of each song on a tape and plays the
first 10 seconds (approximately)
ularly useful to rapidly check the contents of a cassette.
When the AMCS button is pressed during forward
playback, the tape is rapidly wound to the beginning Of
the next song and, as the play indicator flashes on and off,
the first 10 seconds of that song is played. Then the tape is
rapid ly wound to the beginning of the next song and,
again, the first 10 secondsis played. This processis
repeated until the forward
button @ is pressedor the end Of the tape is reached.
When the AMCS button is pressed during
playback, the sameprocessis performed in the reverse
direction. If you want to hear the entire song, press the
forward or reverseplay button @ to cancel the
AMCS function and return to normal playback.
The AMCS circuit operates by detecting the blank sections
between songs. If the spacebetween songsis too short,
the AMCS circuit may go on to the next blank space
of sufficient length. In order to assure that the blank
sections between songs on your cassettes are long enough,
you should usethe auto spacebutton to insert these
spaces when making recordings.
Note:
When AMCS is activated during reverse playback, AMCS
may not operateproperly if a sectionwithin the 10
seconds playedback hasa quiet portion that could be
sensed as a between-songs gap. If this happens, press the
AMCS button again.
Timer Recording and Playback
When connected to an audio timer (optional), the TA•R77
can be set for preset timer recording and playback.
Connect the tape deck and the rest of the audio system to
the timer as shown in the following diagram and test the
arrangement to be sure that timer recording and playback
proceed properly. The direction of tape travel will bethe
direction set immediately before power was last turned off.
