TAPE SPLICING AND EDITING
Cut the tape diagonally with an overlap so that the ends are
lined up. Cutting tape on the diagonal eliminates detection
of the splice in recording. Cover aligned ends with splicing
tape, exerting pressure to secure ends evenly. Trim off
excess splicing tape. Cutting into the tape very slightly will
eliminate the possibility of a sticky splice. Splicing using
scissors requires skillful work. For smooth and easy
splicing, Akai Tape Splicer AS-3 is highly recommended.
HEAD BLOCK CLEANING
The GX (glass and crystal) Heads do not require a great deal
of cleaning. However, if old tapes or tapes which have been
spliced are used, GX head cleaning is also recommended,
Clean recording, playback, and erase heads with a cotton
swab stick which has been dipped in Akai Cleaning fluid
from Head Cleaning Kit HC-SOO.
Pinch wheel and capstan
If foreign matter is allowed to accumulate on the pinch
wheel and capstan, these particles will come off on the tape
causing deterioration of sound quality. Oil adhering to the
capstan also causes irregularity in tape transport. Therefore,
it is also recommended that these parts be wiped clean
periodically. Use Akai cleaning ﬂuid or alcohol.
Do not use chemicals such as chlorothane, etc, for head block
cleaning as the rubber parts will deteriorate.
Prolonged use of the machine will gradually build up
residual magnetism on the heads. The effect of magnetiza-
tion is that it causes a considerable drop in high frequency
response and introduces noise into your recordings. It is
therefore, recommended that head demagnetizing be per-
formed periodically. This can be accomplished with a bulk
head demagnetizer by bringing the prongs of the demagne»
tizer close to the heads and making several small circular
motions over all head surface areas as well as the head
" Turn off the power of the unit prior to demagnetizing the heads.
Do not use magnetized tools in the vicinity of the heads and VU
Do not bring the magnetizer close to the VU Meters.
