SOUND MIXING
Model GX-280D-SS is equipped with independent Line and
Microphone Jacks and input level controls for mixing
signals from two separate sources simultaneously. Record
your own voice accompanied by your favorite combo,
orchestra, etc.
1. Connect power cord and turn on Power Switch.
2. Set Stereo Selector to 2-CH or 4-CH position as
desired.
3. Select tape speed with Tape Speed Selector Switch.
4. With Reset Button, set Index Counter to “0000”. This
Index Counter furnishes a quick reference for locating
positions on the tape.
5. Plug in microphone(s) to Microphone Jack(s) and
connect line output of external source to Line Input of
the GX-280D-SS.
6. Set Monitor Switch to SOURCE position.
7. Adjust and balance microphone input level with
Microphone Recording Level Control and line input
level with Line Input Level Control while observing
corresponding VU Meters. Normal recording level
should not exceed “0” VU.
8. When an optimum level has been determined, while
holding Record Safety Button at depressed position,
depress Forward Button to begin recording.
9. To stop tape travel during recording, depress Stop
Button. See AUTOMATIC STOP & SHUT-OFF.
10. If recording is made in 2-channel, invert reels for
recording on reverse side.
* Mixing can also be accomplished by using the Din Jack and Line
Input connections simultaneously.
* For playback, operate the Stereo Selector according to channels
used in making recording.
TAPE ERASING
Any signals previously recorded on the tape will auto-
matically be erased as a new recording takes place. For
erasing only, load a tape and set recorder to recording
mode. Model GX-280D-SS is equipped with separate
2-channel and 4-channel erase heads. For full track erase,
set Stereo Selector to 4-CH position and for 2-channel
erase, set to 2-CH position. No plugs should be connected
to the input jacks and input volume should be kept at
minimum.
TAPE SPLICING & EDITING
Cut tape diagonally with an overlap so that the ends are
lined up. Cover aligned ends with splicing tape. Press firmly
exerting pressure to secure ends evenly. Trim off excees
splicing tape cutting into recording tape very slightly to
eliminate the posibility of a sticky splice. Tape splicing
using scissors requires skillful work. Akai Tape Splicer
Model AS-3 is recommended for smooth and easy tape
splicing.
TENANCE
HEADS SHOULD ALWAYS BE
KEPT CLEAN
For quality performance, it is imperative that the head
block be kept clean at all times. Dust and magnetic particles
tend to deposit on the heads after prolonged use of the
unit, deteriorating sound quality and sensitivity. The GX
Heads do not normally require cleaning. However, if old
tapes or tapes which have been spliced are used, head
cleaning is recommended. Clean by rubbing the entire head
surface (do not scratch) with a cotton swab stick soaked in
Akai cleaning fluid (from HC-500 Head Cleaning Kit) or
alcohol.
PINCH WHEEL & CAPSTAN
CLEANING
If magnetic particles from the magnetic tape, oil, or other
foreign matter is allowed to accumulate on the Pinch Wheel
and Capstan, irregularity in tape transport may occur
deteriorating sound quality. It is, therefore, recommended
that these parts be wiped clean occasionally. For cleaning,
use Akai Cleaning Kit HC-500, or if Akai cleaning fluid is
not available, use alcohol.
* Do not use chemicals such as chlorothane, etc., as the rubber
wheel will deteriorate.
HEAD DEMAGNETIZING
Normally, the steel pole pieces which form part of the
recording and playback heads become slightly magnetized.
The effect of magnetization is that it causes considerable
drop-out or 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 it close to the heads and
making several circular motions over all head surface
areas as well as the head housing.
* Be sure to cut off the power of the unit prior to demagnetizing
the heads.
* Do not use magnetized tools in the vicinity of the heads.
* Do not bring the prongs of the demagnetizer close to the VU
Meters.
