Akai GX-280 User Manual

SOUND MIXING
For mixing microphone and line input signals, proceed as
follows :
1. Insert microphone plug(s) into microphone jack(s) and
connect line outputs of the external source to line input
of model GX-280(D).
2. Adjust microphone volume level with Microphone
Recording Level Controls and line input level with Line
Recording Level Controls.
Mixing can also be effected by using the DIN Jack and Line
Input connections simultaneously. For playback, operate
Track Selector Buttons according to tracks used in making
recordings,
TAPE SPLICING & EDITING
Fig. 18
Cut tape diagonally with an overlap so that the ends are
lined up (culling Lupe on diagonal eliminates detection of
splice in recording). Cover aligned ends with splicing tape.
Press firmly exerting pressure to secure ends evenly. Trim
off excess splicing tape cutting into splicing tape very
lightly as illustrated by the dotted lines in figure. This
eliminates the possibility of a sticky splice. Splicing of tape
using scissors requires skillful work. For easy and smooth
tape splicing, we recommend Akai Tape Splicer model
AS-3.
TAPE ERASING
Any signal information previously recorded on a tape will
be erased automatically as a new recording is made on the
same tape. For erasing only, thread the tape and set
machine to recording mode. No plugs should be connected
to the recordcr’s input jacks and volume controls should be
kept at minimum. Akai’s Tape Eraser model ATE-7 is
recommended for quick and complete erasure.
HEAD DEMAGNETIZING
Fig. 19
Normally the steel pole pieces which form part of the
recording and playback heads become slightly magnetized.
The effect of magnetization is that it partially erases the
tape, especially at high frequencies. Severe magnetization
which may be caused by using magnetized tools in the
vicinity of the heads, will result in noise or considerable
distortion in addition to the loss of high frequency
response. Although this model already has a built-in head
demagnetizing circuit, it is recommended that demagneti-
zation be performed periodically. This can be accomplished
by touching the heads very lightly with the prongs of the
demugnetizer and making several small circular movements
over all head surface areas as well as the head housing. Akai
Head Demagnatizer model AH-8 is highly recommended for
perfect demagnetization. ;
