* Do not let water or other liquids, flammable
materials, or metal objects such as pins get
inside the X-12.
These things may cause electrical shock or
short circuit the X-12, and damage it.
If the X-12 should become wet, unplug the
AC adaptor from the AC outlet, and contact
your authorized service station.
* When turning the power on, turn the X-12
on first before turning on any equipment
connected to it. Doing so will avoid possible
damage to the other equipment.
Also, when connecting or disconnecting
cables to or from the X-12’s input or output
jacks, make sure that the [LINE OUT/PHONES]
volume is set to “0.”
* When the AC adaptor is connected to an AC
outlet, it will continue to draw small amounts
of power even if the switch is set to off
(STANDBY). If you will not be using the X-12
for an extended period of time, be sure to
unplug the AC adaptor from the outlet.
Accessories (option).......................................................19
Precautions
(please read before use)
Power supply
* When unplugging the AC adaptor from the
outlet, be sure to grasp the adaptor.
Attempting to unplug it by pulling on the
AC cable may damage the wiring.
* It is dangerous to use any power cable that
is cut or frayed. If the power cable is
damaged, immediately stop using it, and
have it repaired.
* Do not plug in or unplug the AC adaptor
with wet hands. Doing so may result in
dangerous electric shock.
* Do not open the unit or touch any parts
inside. Doing so may result in a dangerous
electric shock, and could damage the X-12.
Location
* Avoid using the X-12 in the following
locations:
* Locations of extreme low or high
temperatures, or extreme changes in
temperature.
* Locations with excessive moisture or dust.
* Locations where direct sunlight falls for
an extended time, or near a stove or other
source of heat.
* Locations where electrical voltage varies.
* Unstable locations or where there is
heavy vibration.
* Near strong magnetic fields (on top of a
television or speaker).

Before Using the X-12
<Differences between multitracker and
cassette deck recording>
Boom boxes and stereo cassette decks
record on both the A and B sides of cassette
tape. As shown in Fig. 1, the cassette tape
is divided in 4 tracks of which 2 are used
for the A side and the remaining 2 for the
B side (4 track 2 channel).
<Fig. 1> Boom box / Cassette deck
L ch
B side
R ch
R ch
A side
L ch
A multi-tracker as shown in Fig. 2, all four
tracks can be recorded without turning
over the cassette (four track 4 channel).
For the X-12, the 4 tracks are recorded
one at a time (some multitrackers can
record multiple number of tracks in each
pass). Also, in multitrackers, since all
tracks are recorded in the same direction,
if such a cassette tape is played back in a
radio cassette or cassette deck, tracks 1
and 2 will be heard correctly but if the
tape is turned over, tracks 3 and 4 will be
heard in reverse.
Hint!
You can perform multitrack recording
using a tape that was recorded on a boom
box or a cassette deck. Refer to page 16
for more details.
<Handling cassette tapes>
Cassette tape suitable for recording:
The X-12 is designed to perform best with
high-position cassette tape (TYPE II, HIGH).
We recommended these or their
equivalent.
The tape in C-120 versions (60 minutes
each side) is too thin and not suitable for
repeated recording or playback. Use C-90
or shorter tapes for stable performance.
Using write-protection tabs:
On the spine of a cassette tape are writeprotection tabs that are used to prevent
any recorded data from being erased
accidentally.
You may want to break the tab for side A
and side B of a cassette tape that you have
already recorded, since the X-12 uses all
four tracks at the same time.
If you later wish to record data on a tape
with broken tabs, apply a piece of scotch
tape to cover the tab hole.

** Advice **
Fresh or recorded tapes should not be
kept in locations of strong magnetic
fields (near speakers and TV sets) and
stored in dust free and non-humid
locations.

16. Input jack [INPUT]
Sound sources such as an external mic and
keyboard are connected here.
Input gain should be trimmed accordingly with
the [LINE-MIC] knob located nearby.
17.Gain control knob [LINE-MIC]
Adjust the gain for best S/N ratio.
The output signal level from the sound sources
(mic, keyboard, guitar, etc.) should be set in
such a way that the output of the source should
be neither too high or low. The difference can
be corrected with the gain control.
< Gain control rule of thumb >
The gain is adjusted by rotating the [LINE-MIC]
knob while watching the lighting condition of
the level meter LED as the signal is input.
Gain of "MIC" is obtained at full CW rotation of
the [LINE-MIC] knob and "LINE" at full CCW
rotation.
Ideal gain is obtained by setting the level meter
reading such that the "+6" LED does not light
up. Should the "+6" LED lights up frequently,
it is an indication that gain is too high and will
result in distortion if recording is continued in
this manner.
Basically, the knob should be adjusted toward
"MIC" when a low level sound source such as a
mic is connected, and toward "LINE" when
connecting the output of an effects unit to which
a keyboard or electric base is connected.

slowly advanced, the input monitor sound
will be heard in the headphone.
While monitoring the sound in the
headphone, watch the level meter and adjust
the recording to a suitable level.
Because the recording level cannot be
adjusted with a fader, optimum recording
levels must be determined by the sound
volume applied to the mic or by adjusting
the distance to the mic.
<CAUTION>
If you must monitor for a long time, be
careful not to raise the
knob too high. If you monitor for long
hours at high volumes, it could impair
your hearing.

Model X-12 Owner's Manual
Advanced Operation
At this point, we assumed that you understand recording and playback of each track after
studying the [Basic Operation] section and are ready to move on.
Next up, we'll work on more advanced functions such as multitrack recording - called
"overdubbing" - which is fundamental in multiple recording, then the mixdown process when
sounds recorded to the four tracks will be mixed to stereo, and finally, copying (dubbing) of the
mix to a master recorder (stereo cassette deck, etc.).
1. Overdubbing
Overdubbing is a recording technique used to add a recorded performance to previously recorded
tracks while listening (monitoring) to them.
For example, you might record a rhythm section (such as a drum machine) on Track 1 by
following the basic recording procedure, then record an electric bass on Track 2 while listening
to the recorded rhythm. In this way, you can record performances on all four tracks, one by
one. This section uses an example in which Track 1 has the drum machine already recorded.
Follow the recording steps described in the Basic Operation chapter and use the drum machine
instead of the microphone. We are going to overdub the electric bass on Track 2, the keyboard
on Track 3, and vocal on Track 4.

2. Mixdown
Mixdown is a technique that enables you to adjust the volume balance of the
overdubbed tracks 1-4, combine them to two channels, and dub (copy) to a master
recorder (cassette deck or MD recorder etc.). Refer to the diagram below:
Track 4 (Vocal)
Track 3 (Keyboard)

<CAUTION>
Be careful not to mistakenly press the
[REC]
button.
Remember that the recording track is
always in the selected state.
Insert a tape with tracks 1-4 already recorded
1
into the cassette tray, and rewind the tape
up to the playback start point (reset the
counter to "000").
Connect the input jack of a master recorder,
2
such as cassette deck, and the [LINE OUT
L, R] jacks.
Insert a recording tape (or MD) in the master
recorder and locate the point on the tape at
which you wish to start copying.

"Mini-components" which can be used for
mixdown are limited to types able to
record external inputs.

Set the master recorder to the record standby
mode. (That is, press the [PAUSE] button so
that the level meter will respond, then set the
recorder in record pause mode.)
The method for setting the recorder in record
standby mode will vary depending on the
recorder you are using.
Refer to the instruction manual of the master
recorder for more information.
Adjust the output level and balance (pan
position) of tracks, then adjust input level
on the master recorder.

Play back the tape on the X-12.
While monitoring the sound via the headphones,
use the playback fader and the playback [PAN]
knob of each track to adjust the output level
and balance of the tracks.
Gradually raise the headphone volume using
the [LINE OUT/PHONES] knob. This knob also
adjusts the output level at the X-12's [LINE OUT
L, R] jacks. Set the level so that the level meter
of the master recorder will respond moderately.
After finishing the level adjustments, rewind
5
the tape to the "000" point.
Now you can begin mixdown.
6
First start recording on the master recorder,
then press the [PLAY] button on the X-12 to
start playback.
After mixdown is complete, stop the X-12 and
7
the master recorder.
<Note>
You can position the sound on tracks 1-4 anywhere in stereo image on
mixdown.
This is where your creatively is important. Try for a sound that is pleasing
to you!
Using a tape recorded on a boom box or cassette deck
You can record your favorite music on a boom box or cassette deck and overdub your
performance or vocal, accompanying your musician's performance to make your own
original tape. Follow the procedure below to make this type of tape.
1. Record your favorite music source on the boom box or cassette deck.
<NOTE>
Be sure to record on only one side of the tape (side A or B).
That is, use Track 1 and 2 to record on the jam box or the cassette deck, and keep
Tracks 3 and 4 empty. (See the diagram below.)
Track 4
Track 3
Track 2 (R channel)
Track 1 (L channel)
Do not record now. Later, you will record your
performance or vocal here on the X-12.
Record your favorite song to Tracks 1 and 2 on the
boom box or cassette deck.
2. Insert the recorded tape in the X-12, and follow the "Overdubbing"
procedure described previously to record your performance or vocal
to Tracks 3 and 4.
<NOTE>
Note that the law prohibits recording copyrighted or broadcast music, except for
recordings intended only for personal use.

Troubleshooting
Model X-12 Owner's Manual
Symptom
The power is not turned on
when you press the power
switch on.
Sound flutters or skips.
The sound distorted or
clipping.
The [REC] button is not
pushed in.
The sound cannot be heard
through the headphones.
You cannot record to a
desired track.
Is the AC adaptor plugged in securely?
Is the head dirty?
Are you using a type of tape other than high
position?
Is the level appropriate for the input signal?
Is the write-protection tab on the cassette
tape broken?
Is the [LINE OUT/PHONES] knob turned
up?
Is the [REC TRACK] selector set correctly?

Maintenance
* Cleaning the exterior
For normal cleaning, use a dry cloth.
For stubborn dirt, moisten a cloth in diluted
detergent, wring it out firmly, and wipe the dirt
off. Then polish with a dry cloth.
Never use solvents such as alcohol, thinner or
benzene, since these will damage the printing
and finish of the exterior.
Check the connection at the AC outlet and
the [DC IN] jack of the X-12.
Clean the head.
Use a high-position tape.
Use the [LINE-MIC] knob to set the optimum
level.
Place a strip of scotch tape over the broken
tab.
Turn the [LINE OUT/PHONES] knob.
Set the [REC TRACK] selector repeatedly
until the desired track is selected.
or even damage the tape by pulling it out of
the cassette. Since cassette tape is very thin, it
is especially dangerous to use a cassette deck
with dirty pinch rollers. As with the head, it is
important to always keep these parts clean.
Clean them using a cotton swab or gauze soaked
in cleaning solution or isopropyl alcohol. Never
use organic solvents such as lacquer thinner,
since this will severely damage the pinch rollers.
* Cleaning the head
As the X-12 is used, the record/playback head
will become coated with oxide residue from the
tapes. If this residue is allowed to build up,
recordings will contain more noise, and
dropouts may occur during playback.
To prevent this, regular cleaning is important.
Use a commercially available cleaning kit etc.
to clean the head. If cleaning the head does
not restore the sound quality, it is possible that
the head is worn. Contact an authorized Fostex
service station for repair.
* Cleaning the pinch roller and capstan
The capstan and pinch roller are important
parts that hold the tape and move it along at
the correct speed. As with the head, these parts
can also become dirty with oxide residue and
dust, which will cause increased wow or flutter,
* Demagnetizing the head
After long periods of use, the head begins to
develop a magnetic field in addition to the oxide
residue described above. This can also occur if
a magnet or a magnetized object (scissors, etc.)
is allowed to come near the head or touch it. If
the head or capstans become magnetized,
frequency response will be degraded and noise
will increase.
In extreme cases, noise can be created on
previously recorded tapes that you playback,
rendering them useless. Once a month or so,
you should use a demagnetizer (head eraser)
to demagnetize the head. Carefully read and
follow the instructions included with your
demagnetizer, and do not allow it to come near
recorded tapes.
