1.2 Some safety notes and precautions
•
Always use the PS-P2 power adaptor
supplied with the Porta02. If you use
any other adaptor, there is a risk of
damage, or even fire. Make sure that
the input voltage marked on the PS-P2
adaptor matches the power supply you
are using. If you are in any doubt, con-
sult your TASCAM dealer.
Turn off your Porta02 and remove the
cassette when you are not using the
Porta02. If you will not be using it for
an extended period of time, unplug the
PS-P2 adaptor.
•
When connecting or disconnecting the
Porta02 to or from any other equip-
ment, make sure the power to the
Porta02 and all other equipment is
turned off. This will avoid possible
damage to equipment.
Do not keep your Porta02 in a very
hot place. Remember that in sunny
weather, the inside of a parked car
heats up very quickly. Avoid leaving
your Porta02 in such a place.
•
•
•
Do not spill liquid onto your Porta02.
Avoid eating, drinking and smoking
near it (smoke particles are bad for

audio equipment). If any liquid or any
objects such as paperclips, guitar
picks, etc. fall inside the Porta02, do
not try to operate it. Return it to a
TASCAM service center for repair.
If the case of the Porta02 becaomes
dirty, clean it only with a damp (not
wet) cloth, moistened with a little
detergent. Do not use solvents or thin-
ners, etc. to clean the Porta02, as these
will damage the surface.
There are no parts inside the Porta02
that you can repair by yourself. Do not
open the Porta02 case or try to make
any repairs. Return it to a TASCAM
service center for repair.

30 minutes, a C40 for 20 minutes, etc.).
Only use Type II (chrome or CrO ) cas-

settes with the Porta02. Find a reliable
brand and stick with it. The time you
spend creating your multitrack master is
worth much more than the small differ-
ence in price between cheap and high-
quality cassettes. High quality cassettes
will cause you fewer problems in the long
run.
NOTE
Never use C120 cassettes with the Porta02. The
tape in these cassettes is thin, and may stretch
and break.
Always store cassettes in a safe place
(away from the magnetic fields produced
by speakers, television sets, computer
monitors, etc.).

and restore the sound quality.
WARNING
Only use head and rubber cleaning fluid and
cleaning swabs designed for use with tape
recorders. The use of any other cleaning materi-
als may cause damage to the Porta02.
In addition to affecting performance by

gaps, dirt and oxide in the tape path will
also act in the same way as very fine
sandpaper, which will wear down internal
parts of the Porta02, and affect the
recording in this way as well.
Clean the heads and metal parts of the
tape path before every session with the
Porta02 and also after every session.

All of these problems can be avoided if
you buy a head cleaning kit such as the
TEAC TZ-261 and keep it with your
Porta02 for regular use. The kit consists
of head cleaner, cleaner for the rubber

1.3 What you need to make recordings
Apart from the Porta02 itself, you will
need:
•
Some monitoring equipment (some
kind of amplifier and speaker system).
•
Headphones, if you intend doing any
work with microphones. These will
avoid acoustic feedback (“howl-
round”) when recording. Additionally,
headphones are sometimes useful
when panning tracks on mixdown, as
you can hear the precise position of
each track.
•
Some kind of stereo mastering
recorder to produce the stereo record-
ings. This can be a cassette recorder
such as the TASCAM 102Mk II or an
MD recorder such as the TASCAM
MD301. A recorder which does not
have recording level controls is not
suitable for use as a master recorder.
•
You will also need RCA (pin or
phono) cables to connect the Porta02
to other equipment.
•
Of course, you will also need some
kind of sound source to record (instru-
ment or microphone, etc.).
1.4 Connecting the Porta02
1) Make sure all the equipment is
turned off.
You can listen to the Porta02 by selecting
the amplifier’s input source to be from the
terminals to which you connected the
Porta02 (AUX or VIDEO, etc.).
2) Connect the LINE OUT terminals of
the Porta02 to the amplifier, using
a pair of terminals on the amplifier
such as AUX or VIDEO.
When you have mixed down and you
want to listen to the mixed tape, you
should select the mastering recorder as
the amplifier’s input source.
NOTE
Do not use any terminals marked PHONO or
intended for record decks. These are connected
to a special circuit inside the amplifier which
makes them unsuitable for anything except
record decks.

This 1/4” jack allows you to connect a
pair of stereo headphones to the Porta02.
Use this jack to connect the PS-P2 AC
adaptor which comes with your Porta02.
When connecting the power, make sure
the power switch is off (slide it to the
right, as you look from the back).
WARNING
Do not use headphones equipped with a mono
jack. This will cause damage to the Porta02’s
headphone amplifiers.
WARNING
DO NOT use any adaptor with the Porta02
except the PS-P2 adaptor which comes with the
Porta02.

PHONES LEVEL
This control adjusts the volume in head-
phones connected to the PHONES jack.
Turn clockwise to increase the volume.
There will be no output from the
PHONES jack when the control is fully
counter-clockwise. It has no effect on the
level from the LINE OUT connectors.
[2]
MIC/LINE 2
Use this 1/4” phone jack to connect the
second channel audio source (instrument
or microphone) to the Porta02.
WARNING
[7]
MONO switch
The Porta02 is designed to record signals from
microphones, CD players, tape decks and musi-
cal instruments. It is not designed to record sig-
nals which come from the speaker outputs of
any amplifier or equipment. If you try to plug
such signals into the Porta02, you will almost
certainly damage both the Porta02 and the other
equipment.
When this switch is pressed down (in), it
changes the stereo signal from the
PHONES jack into a mono signal (the
same signal will be output from both the
left and right channels). Press it again to
return it to the “out” stereo position. It
does not affect the signal from the LINE
OUT connectors.

(1 and 2)
These switches control where the signals
coming into the MIC/LINE jacks will be
recorded. For both switches 1 and 2, the
center position is marked as SAFE. When
a switch is in this position, no signal will
be recorded on tape. However, you can
still listen to the signals coming into the
MIC/LINE jacks and view the levels on the
meters.
[9]
POWER indicator
This yellow light is lit when the Porta02
is connected to the power supply and
switched on.
When set to a number (1 or 3 for channel
1, or 2 or 4 for channel 2), the signals
input to the channel will be recorded on
the track whose number has been set on
the switch. This is called “assigning” or
“routing” channels to tracks.
[10] Tape counter and reset
button
The tape counter allows you to note dif-
ferent parts of the tape and locate to
them. Press the reset button to reset the
counter to “000” at any time (we suggest
that you only do this at the beginning of a
recording).
[14] Channel meters (1 and 2)
Each channel has a set of four LED indi-
cators which show the level of the signals
sent to the LINE OUT L and R jacks.
Exactly what is metered depends on the
REC FUNCTION switch settings, but gen-
erally, they display the signals at the MIC/
LINE IN jacks, and when the input chan-
nels are set to SAFE, the meters show the
off-tape signals, whose levels and pan
positions are set using the OUTPUT
LEVEL and PAN controls.
[11] OUTPUT LEVEL controls
These controls change the levels of the
four tape tracks in the LINE OUT and
PHONES outputs. When one of these con-
trols is turned fully counter-clockwise,
the tape track corresponding to that con-
trol will not be heard in the LINE OUT and
PHONES outputs.

up.
These controls change the position of the
four tape tracks in the stereo LINE OUT
and PHONES outputs. When one of these
controls is turned fully counter-clock-
wise, the sound of the corresponding tape
track will appear to come from the left,

3 Making your first recording
3 – Making your first recording
This section describes how to make a 4-track recording using the
Porta02. For this, we will assume that you are making a recording
recording a part of a stereo CD or cassette on the other two tracks (3
and 4). Make sure you know what you are going to say.
Start by making sure that you have all the equipment listed in 1.3,
“What you need to make recordings”.
3.1 Setting up
1) Make sure all equipment is turned off.
2) Connect the LINE OUT jacks of the Porta02 to the AUX IN
3) Connect the mastering recorder REC IN and PLAY OUT jacks
to the appropriate jacks of the amplifier. See 1.4,
“Connecting the Porta02” if you are not sure what you
should be doing here.
4) With the INPUT 1 fader at the 0 position, plug the
microphone into the MIC/LINE 1 jack. Do not plug anything
into the MIC/LINE 2 jack.
If the microphone has a switch, make sure this switch is off.
5) Plug the stereo headphones into the PHONES jack of the
Porta02.
6) Turn on the Porta02, the mastering recorder, and the
amplifier (in that order).
3.2 Getting ready
1) Clean the heads and pinch roller (see 1.2.4, “Cleaning the
heads” and 1.2.5, “Cleaning the pinch roller”).
2) Insert a Type II (chrome) cassette.
The tape should be towards the front of the Porta02, and the full spool
should be on the left side. Put the non-tape part of the cassette in first,
and then push the tape (front) down into place
13
3 Making your first recording
3) Play the tape for about 10 seconds and then stop the tape.
4) Press the counter reset button.
3.3 Setting the level
The aim of this section is to teach you to set the input level so that
the average signals coming from the microphone will light the 0
meter indicator, and the loudest will light the +6 indicator.
1) Make sure all OUTPUT LEVEL controls are set to 0. Put on
the headphones and set the PHONES LEVEL to the 0 position.
If you do not do turn down the speaker volume, you will probably get
feedback (“howlround”) when you start using the microphone.
2) Set both TRIM controls to the LINE position.
Although you will probably end up with this control at the MIC posi-
tion, or close to it, for now, set it to LINE.
3) Take the INPUT 2 fader to the 0 mark. Bring the INPUT 1
fader up to between the 7 and 8 marks.
This is called the “nominal” position, and is the position where the
electronics controlled by the fader will not have to amplify the signal
too much (causing noise) or have too much signal going into them
(causing distortion).
4) Switch the microphone on if necessary. Speak into the
microphone at the volume you will be recording.
It is important than when you perform these level checks that you
speak, sing or play at the level at which you will actually be recording.
Most people, when they first start recording, tend to be a little louder
than when they are simply checking the levels.
5) While talking into the microphone, turn the INPUT 1TRIM
control clockwise until the left 0 indicator is lit most of the
time, and the +6 indicator is lit on the loudest parts.
If the 0 indicator hardly lights at all, you may be too far from the
microphone, or you are speaking too softly. If the microphone uses
batteries, you may need to replace them.
You can also bring the fader up from the 7-8 position to increase the
level, but you should do this only after the TRIM control has been
turned fully clockwise.
6) Adjust the PHONES LEVEL until you are comfortable with
what you hear in the headphones.

3 Making your first recording
3.4 Recording the first track
1) Set the REC FUNCTION switch of INPUT 1 to 1.
You are now ready to record on track 1. Make sure the REC FUNC-
TION switch of INPUT 2 is set to SAFE, so you don’t record on it by
accident.
2) Press the RECORD key (which will also press the PLAY key)
and start recording the first spoken track.
If the level as shown by the meters now seems a little high, you can
“back off” on the fader a little.
3) When you have finished (try to keep speaking for at least a
minute), press the STOP key.
4) Rewind the tape to the 000 mark.
5) Start playing the tape, and adjust the LEVEL and PAN
controls of track 1 so that you can hear clearly what you
have just recorded.
Note that meter 2 now shows the level of the tape replay on the right
LINE OUT, rather than what is being input to the tape.
NOTE
You may notice a difference between the sound you hear when you replay the
tape and the sound you hear when you are recording. This is perfectly nor-
mal, and is due to the way that the Porta02 lets you hear previously-recorded
material.
6) Rewind and replay the tape again, listening carefully to
your recording.
7) Rewind and re-record the track as many times as you think
necessary.
Of course, this is only a test, so it doesn’t matter too much, but when
you’re making a real recording, it’s important to make the recording
as good as possible.
8) When you’re happy with the recording, set the REC
FUNCTION switch of INPUT 1 to SAFE.
If you replay now, both meters will now show off-tape monitoring
15
3 Making your first recording
3.5 Recording the next track
Since you plugged the microphone into MIC/LINE 1 / MONO, and
didn’t plug anything into MIC/LINE 2, the microphone signal is split
as if it was plugged into both channels.
1) Take fader 1 to the 0 mark.
2) Set the level for input channel 2 in the same way as you set it
for input channel 1 (see 3.3, “Setting the level”).
3) Set REC FUNCTION switch for INPUT 2 to 2.
You are now ready to record on track 2.
4) Rehearse your second spoken part by playing back the first
track (adjusting the level and pan if necessary) while
speaking the words for the second track.
5) Rewind and record when you are ready.
When you are recording, the meter of INPUT 2 will show the input
levels of input 2. Since the signal is now going to track 2, the meter
for input 1 will not show anything.
6) Rewind and playback when you have recorded. Adjust the
level and pan position of the two tracks with the LEVEL and
PAN controls for tracks 1 and 2.
Remember that the fader adjusts the level of what goes onto tape, not
the replay levels.
When you are playing back, the meter of INPUT 1 will show the level
of the signal from the left outputs, and the meter of INPUT 2 will
show the input signal level as long as the REC FUNCTION switch is
not SAFE.
7) Rewind and repeat the recording of track 2 until you are
satisfied with it.
SAFE input channel 2, and take both faders down to 0. Set
the TRIM controls of both inputs to LINE.

3.6 Recording the stereo backing
Now that tracks 1 and 2 are filled with spoken words, we’ll put
some backing music behind them. We’ll assume that you’re using a
CD player here (of course, it may be an MD player or a cassette
player).
NOTE
This is a test recording and will not be used except as a test. However, if you
are making recordings for public performance or distribution which include
pre-recorded copyright material, you should be aware of the regulations con-
cerning copyright in the area where you live. Unauthorized recording of copy-
right material may be illegal.
1) Make sure the volume on the amplifier is turned all the way
down (it should already be turned down).
2) Take off the headphones and unplug the microphone.
3) Connect the left and right LINE OUT of the CD player to MIC/
LINE inputs 1 and 2 of the Porta03.
4) Set the REC FUNCTION switches of INPUTs 1 and 2 to 3 and 4.
You are now ready to start recording on tracks 3 and 4.
5) Start playing the CD track you will be recording. Adjust the
faders so that the +6 meter indicators light on the loudest
parts of the CD.
6) Slowly turn up the amplifier volume so that you are
listening at a comfortable level.
7) Make the CD ready to play, and make sure that the Porta02
is rewound to the start of the recording.
8) Start recording, and start replaying the CD.
9) When you come to the end of the CD material, stop the CD
and Porta02, and rewind the Porta02 tape to the beginning
of the recording.
17
3 Making your first recording
3.7 Mixdown
Make sure that your mastering recorder is connected to the monitor-
ing system.
1) Set both REC FUNCTION switches to SAFE, and move both
faders down to 0.
This will stop any extra unwanted noise from the inputs appearing in
the final mix.
2) Make sure the mastering recorder is ready to record, and
put it into record pause mode. Do not start recording yet.
If you are using a tape for mastering, make sure that you are not
recording over anything you want to keep. If you are using a new tape,
make sure that you have taken the tape past the leader portion. Make
the noise reduction, etc. settings on the mastering recorder, which will
give you the best sound quality.
3) Play back the recording on the Porta02 and adjust the
OUTPUT LEVEL and PAN controls on the Porta02.
The nominal position (the best position) for the LEVEL controls is
about the 2 to 3 o’clock position. This is the position you should
regard as normal.
It is usual to put the PAN controls for a stereo source such as a CD
fully right and fully left.You can place the two voices anywhere in the
stereo picture.
Practice adjusting the levels of tracks 3 and 4 together to fade the
backing music in and out.
4) While adjusting the levels on the Porta02, watch the
recording levels on the mastering recorder. If they are too
high, take down the recording level on the mastering
recorder.
Remember that if you are recording on a digital recorder, such as an
MD recorder, if the signal levels are too high, the result will be
extremely unpleasant distortion. Analog recorders, such as cassette
decks, will also distort if the levels are too high, but the distortion is
much more pleasant (even so, you should try to avoid distortion in the
mixdown).
5) When you are happy with the mix rehearsal, rewind to the
start of the recording on the Porta02.
6) Start recording on the mastering machine, and start
playback on the Porta02.
18
3 Making your first recording
7) Mix the tracks, fading the backing music on tracks 3 and 4
to taste.
8) At the end, stop both machines. Rewind the mastering
recorder.
9) Set the amplifier input source to the mastering recorder,
and replay your mix.
10) If you are not happy with the mix, you can do it again,
either recording over the old mix, or adding the new mix
after the old one.
Congratulations! You have now completed your first recording
project with the Porta02. Rewind the Porta02 tape to the start,
remove it, and clean the Porta02’s heads.

4 Hints and advanced tips
4 – Hints and advanced tips
This section gives a few hints and tips
which may be useful to you when you
make recordings using the Porta02.
4.1 Recording techniques
Learning how to record is an art, not a you, and there are several good books on
science. One of the best teachers is expe- the subject which can explain the theory
rience. However, there are a few things of recording and some of the techniques.
mentioned here which may be useful to
4.1.1 Recording electric guitars
Much of the sound of an electric guitar
(and also bass) is due to the effects,
amplifier and speakers, as well as the gui-
tar and style of playing. If you plug the
guitar straight into the Porta02, you will,
of course, be able to record it, but the
sound will probably not be what you are
used to.
4.1.2 Recording with effects
Professional recordings often use effects
like digital reverberation on vocals, etc.
You can add some of these effects by
plugging the microphone into an effects
unit, and plugging the unit into the
Porta02. Note that the effects unit must
be able to accept microphone-level sig-
nals, and will output to the Porta02 at
LINE levels.
Plugging effects units between the guitar
and the Porta02 will certainly help to pro-
duce a fuller sound. The sound which
will come closest to a live sound, though,
will be provided by the amplifier itself.
In addition, you will need to use the inter-
nal balance control in the unit to decide
how much of the “dry” (un-effected)
sound will be passed through to the
Porta02 for recording.
You can adopt one of two approaches:
either to put a microphone in front of the
guitar speaker and record this (at MIC
level), or to connect the output of the pre-
.amplifier to the Porta02 and record at
LINE level.
If you do not have access to a reverbera-
tion unit, you can try recording vocals in
a very “live” room (without much furni-
ture).
WARNING
Do not connect the speaker output (or head-
phone output, if provided) of the amplifier to
the Porta02. This will almost certainly dam-
age the Porta02, and may damage the ampli-
fier. Only use outputs which are marked
LINE OUT, PRE OUT, DIRECT OUT
and so on. Avoid using any outputs marked
SPEAKER OUT, SP OUT, 4Ω, 8Ω, 16Ω
or the like.

left LINE OUT (channel and meter 1) or
the right LINE OUT (channel and meter
2). If a signal is also received at the MIC/
LINE input jacks, this will be added to the
playback for metering.
The meters display the input levels to the
channels at all times except when playing
back with the input channels in SAFE
mode.

SAFE.
3) Connect the source for the extra
inputs to the MIC/LINE jacks and
adjust the TRIM controls to match
the level.
These extra inputs will be panned either
fully left or right (or one track will be in
the center) and the mix proceeds as the
extra inputs are recorded. This method is
therefore useful for adding a pre-recorded
stereo backing to go behind the four
recorded tracks.
4) Play back the tape, and use the
OUTPUT LEVEL and PAN controls to
adjust the playback of the tape
tracks.
5) Use the faders to adjust the levels
of the input signals against the tape
tracks.

Porta02.

machine, as the Porta02 does not use
noise reduction. Of course, on the
final stereo mix, you can use noise

•
Once you have mixed the four tracks
to two, you cannot adjust their levels
or pan positions again on the new
tape. Think ahead to what tracks you
will record on the new tape, and mix
accordingly.
There are a few points to remember:

Although you can repeat this process
of mixing 4 tracks to 2 and then add-

point where the quality becomes unac-

When using this technique, always use
the same type of tape in the Porta02
and mastering machine. Differences in
tape type may affect the sound.

The mastering recorder must have its
noise reduction turned off when mix-

When monitoring while recording, the sound will often be a little
different to when it is played back. A large amount of distortion
may be caused by recording at too high a level (shown by the meter
+6 indicator being lit all or most of the time). Adjust theTRIM
level and/or back off on the faders.
Recorded sound is distorted
when recording
If the meter +6 indicator is not constantly lit, you may want to
reduce the headphone level; you may be driving the headphones
too hard.
Either the sound was recorded at too high a level, or the summed
level of all four tracks is too high. Try reducing the level of all
tracks so that the meter +6 indicator is not constantly lit on play-

You’re probably listening to tracks 1 and 2 forwards at the same
time as 3 and 4 backwards. Turn down the OUTPUT LEVEL con-
trols of tracks 3 and 4.
A stereo tape recorded on
