FEATURES
High Quality Long Life “S & S’’ Sendust Head
Onkyo’s recently developed “S & S’’ Sendust head (made
from a highly robust silicon/iron/aluminum alloy of out-
standing magnetic properties) plays a very big role in
achieving the high quality of sound reproduction in the
TA-630D. Extended frequency response (20 Hz ~ 18,000
Hz with chrome tapes) and an exceptionally wide dynamic
range make your recordings sound professional-like.
Built-in Accu-Bias Control
Optimum bias level is essential for really top grade record-
ings. But since the magnetic characteristerics of different
types of tape vary from brand to brand, the conventional
bias settings are only approximates. The Onkyo TA-630D
Accu-Bias control eliminates the “‘approx”, and ensures
you of superb results with every tape used, especially in
the high frequency region.
Dolby NR System with Switchable MPX Filter
Now a regular feature in all high grade cassette tape decks,
the Dolby NR system eliminates. much of the annoying
tape hiss from your recordings. And by also incorporating
the Dolby circuit in a highly reliable single-chip 2-channel
monolithic IC, outstanding channel balance is achieved.
Furthermore, a built-in MPX filter removes the pilot signal
from FM broadcasts for brilliant high quality recordings.
Built-in Dolby FM Decorder
With the TA-630D you will be right up to date for record-
ing of the increasingly popular Dolby FM broadcasts. No
need for an extra adaptor, or a new tuner/receiver
especially designed for Dolby FM. The improved S/N ratio
makes noise practically non-existent.

Timer Switch for Automatic Recording or Morning Alarm
By simply connecting up to an audio timer, the TA-630D
will record those “not-to-be-missed” programs even in
your absence. Or then you may wish to substitute your
morning alarm with some of your favorite symphonies and
recording artists.
One-Touch Rec Muting for Clean Editing
This simple switch will make a big difference to your tape
recording and editing. Since tape transport will continue
in a “no-signal” recording mode, the interval between tunes
will be completely silent. Editing out of commercials will
also be swift and clean-cut.
Memory Rewind for Rapid Replay
After presetting the tape counter and memory rewind at a
particular section of the tape, a simple push of the rewind
rewind button will return the tape back to that point quick-
ly and accurately, saving considerable time and bother.
Separate 3-Way Bias and Equalization Selectors
The TA-630D is designed to handle all major types of
cassette tapes available on the market today. And in com-
bination with the Accu-Bias control, optimum bias levels
are assured for every tape used.
Full Auto-Stop Mechanism .
Full automatic stop at the end of the tape safeguards both
tapes and tape transport from undue strain.
The TA-630D is also equipped with an electronically con-
trolled full auto-stop mechanism to ensure that no strain
whatsoever is applied to either tape or tape transport
system.
