BIAS and EQualization switches have been incorporated so you
can match the Deck to the tape you use. We use both to give you
extra versatility — so you can use any of the new tapes now availa-
ble (and to make sure your Deck will be compatible with any future
tape developements). Typically you'll want to use Cr02 positions
for Chromium Dioxide tapes.
And use NORMal for all other
tapes. However, you may firid you'll get better results with some of
the special tapes if you use Cr02 Bias and NORMal Equalization
settings for recordings.
We suggest that if you are using one of the special formulation tapes,
try different combinations till you obtain the one which results in
the best overall level, frequency response and lowest noise.
NOTE: BIAS functions only during Record mode (has no effect
during play). EQ functions in both Record and Play.
The Dolby System incorporated in your Tape Deck will enable you
to make tape recordings with substantially improved signal-to-noise
ratio, which gives the effect of extending dynamic range. It will
provide approximately 10 dB improvement in signal-to-noise in the
frequency range of tape hiss-noise.
You can duplicate tapes by recording from another tape deck/
player or put 8-track tape programs on cassettes. Or, you can put
your favorite records onto cassettes. Make appropriate connections
from another tape player or phonograph to the LINE IN jacks as
noted previously.
Storage of tape is no major problem, provided you do not expose it
to extreme temperatures or high humidity. Also, do not expose
your tapes to magnetic fields (magnets, large transformers, etc.).
Avoid dust and dirt. You may find storage containers to be extreme-
ly useful accessories; see your local Radio Shack store.
Demagnetize the tape heads and clean the tape handling parts pe-
riodically
this will insure maximum frequency response and
lowest noise. After a few hours of recording or playing, dust, lint
and tape oxide will begin to build up on the tape heads and guides;
this affects record and play quality. To achieve the professional
quality this system is capable of, such dust, line and oxide must be
cleaned off. Also, the heads tend to retain residual magnetism after
some hours of use
this introduces noise on both record and
playback. To clean, we recommend using Radio Shack Catalog
Number 44-1160 Cassette Head Cleaner or use cleaning sticks (44-
1093) and Recorder Cleaner ( 44-217).
To remove residual
magnetism, use a Tape Head Demagnetizer such as 44-211 or 44-
215. Or, the easiest way to do this is to use a 44-631 Cartridge
Cleaner/Demagnetizer.
REALISTIC GUIDE TO TAPE RECORDERS is a very helpful pub-
lication available at your Radio Shack store. It has a number of
interesting chapters covering practical aspects of tapes, recorders
and accessories, plus a number of hints to enhance enjoyment of
your Realistic Cassette Tape Deck.
