The art of
recording now takes another step forward.
Cassette
tape decks have really come into a world of their own, thanks to the many
technical breakthroughs accomplished by some very ingenious engineers. The
Dolby noise reduction, vastly improved tape heads, peak level check meters,
chromium dioxide tape cassettes and stabilized tape transport are just some of
the many reasons for the cassette deck's rise into the ranks of top quality
high fidelity systems. This should be enough to satisfy even the most
professional type of audio fan, but Technics engineers weren't happy. Their
constant striving for even better and better systems has produced a real
classic in cassette tape decks - the RS-630 where all controls and tape loading
are operated from the Front. With the RS-630, you not only have all that's best
in the latest cassette deck technology, you have it all there on the front
panel, bringing it right into line with your other Hi-Fi components.
Separate
bias and equalization selectors for optimum recording with any type of tape.
The RS-630
can make full use of the quality potential of any kind of cassette tape - be it
normal, LH, chrome or the new ferric-plus-chrome types. With its separate bias
current and equalization selector switches, optimum conditions can be
estabilished for any tape, to give you recordings of even,balanced frequency
response, excellent dynamic range and finest signal-to-noise ratio. It's you
who chooses the tape - not the machine.
Outstanding
peak check meters.
All music
contains short sharp signal peaks which are several times more intense than the
average signal level. These peaks may well overreach the tape's ability to
accommodate them, resulting in distorsion. To avoid this,the deck's recording
level may be set to a lower position, but if set too low, tape noise may become
noticeable during quieter passages. Accurate adjustment of recording level is
then very important, and this is where the unique peak check meters play a
major role. These two large, easy to read meters can give both
"conventional" level readings (which are more or less averaged
readings), and peak check readings where they respond to even the shapest
signal peaks. This will go a long way in
making genuinely high quality tape recordings.
The Dolby
noise reduction
The Dolby
noise reduction system has greatly improved the quality of cassette tapes by
removing much of the background noise. Technics was very quick to adopt the
Dolby system as a standard feature for
the discriminating audio fan. The Dolby system removes the hiss-like tape
noise, particularly noticeable during the quieter lulls, by boosting high notes
duriug recording. In playback, the Dolby circuit reduces the boosted notes back
to their previous levels, but at the same time reduces the tape hiss to a much
lower, almost inaudible level. It's no wonder that the Dolby system has become
a standard feature for the keen audio enthusiasts.
HPF head
with extremely long service life.
One of the
major drawbacks in any tape recording has been the constant wear and tear on
tape heads. But now Technics engineers have also overcome this problem with
their extremely long life HPF heads which withstand even the longest wear and
tear. They are guaranteed to last at least for 10 years, far beyond the best
performance of normal heads.
Output level
control
This control
is essential if you want to adjust the cassette deck's output to the same level
as your tuner and turntable, etc. You will need no further adjustment of your
amplifier volume control, and will be free to switch from component to
component all at athe same volume.
Front
loading makes cassette decks a full member of the component family
Now you can
stack your cassette tape deck righ along, or right on top, pf your other
components. Neat and tidy, and space-saving, yet still with the same high
quality precision performance as before. Note the flood-lit compartment with
its sliding door and easily accessible tape heads for easy cleaning and
demagnetization.
Plus a host
of other value features.
Auto-stop at
end of tape prevents undue strain.
Lockable
pause button for quick interruptions of recording or play.
Big, handy
play and stop buttons.
Tape
transport clearly visible, thanks to illuminated cassette compartment with two
mirrors.
Connectors
include; mic inputs, line inputs, line outputs, DIN-type Rec/Pb connector,
stereo headphones jack.
