Introduction
This manual covers the
122
MKIIl,
I l 2R
MKII,
and I
12
MKII.
Your new TASCAM deck
is
a professional rack-mount 4-
track, 2-channel recorder/reproducer designed to offer
outstanding audio perfom1ance and convenient features.
Speed in operation is enhanced
by
CPS (Computomatic
Program Search)
(I
I 2R MKII only), 2-point Autolocator,
and Return-to-zero. Dolby* HX Pro
is
provided
to
improve
high frequency response. The bias
is
automatically set
to
its
optimum value for each tape in use ( except for the 122
MKIII).
With the 122
MKIII,
a built-in oscillator (400 Hz
and
IO
kHz) along with individual Bias and Level trimmers
can be used to maximize performance with any tapes. The
3-head design
of
122 MKIII and l l 2R
MKII
produces real-
time, off-tape monitoring.
We suggest that you read this manual thoroughly
before using the machine. Even though a quick glance
will get you going, careful study will ensure that
misunderstanding won't slow
you
down.

1. POWER : Switches power on to the unit.
Each time you turn
on
the deck, the last on/off status
of the ADJUST switch (122
MKIII only) and Auto
Reverse (
c--.:>
/
:::::::::,
) switch (112R MKII only) and
the last play/record direction as set with the
DIRECTION switch (112R MKII only) are retrieved from
a backup memory.
2.
EJECT : Opens the cassette compartment.
3. PITCH CONT : Provides about a plus
or
minus
12
%
variation to the tape speed
in
both Play and Record modes.
Unless you use the function intentionally, make sure that
the knob is at its OFF position for the tape to roll at
nom1al speed (1-7/8 i.p.s. or 4.8 cm/sec.).
4.
REW : Winds the tape at high speed
in
reverse.
If
pressed during Play Pause, enables reverse cueing.
5. F.FWD : Winds the tape at high speed
in
the forward
direction.
If
pressed during Play Pause, enables the forward
cueing.
6. STOP : Stops all tape motion.
7. PLAY : Starts playback.
If
pressed together with
RECORD, starts recording.
If
pressed during Record Pause,
resumes recording.
8. PAUSE : Temporarily stops play
or
recording ; to
resume the function interrupted, press PLAY.
If
pressed
together with RECORD, activates Record Ready mode,
allowing you to start recording
by
pressing PLAY only.
9.
RECORD : Starts recording when pressed together with
PLAY.
10. Tape Counter : Displays the distance from a zero
reference point, selected by pressing RESET (-99
M 59 S
to 99
M 59 S with the 122 MKIII and I I 2R
MK.II
;
or
00
00 to 99 99 with the 112
MKII).
A type of tape
in
use (NORMAL, CrO2
or
MET AL) is
indicated on the right hand side
of
the tape counter, and the
monitor source
too-"INPUT"
lights unless tape signal
is
feeding the front PHONES and rear OUTPUT.
6
NOTE
122 MKIII and 112R MKII : The tape counter is not a
clock. Its reading depends
on
the tape length, relative
tape packs on both reels and other mechanical
factors. Use a watch to measure the correct length of
particular program.

counter and a clock (from beginning
to
end, one-way
run) :

11. INPUTS, L and R : Allow individual control
of
both
channel levels.
122
MKIII
: Both controls are geared together to allow
simultaneous adjustment
of
the record level
of
both
channels. Each channel can be adjusted independently
by
holding one knob and turning the other.
12.
VU
meters : Indicate input
or
tape signal levels
depending on the transport mode and the MONITOR switch
setting.
13. MONITOR : Setting to INPUT routes the input
signal to the PHONES and OUTPUT jacks, whatever the
transport mode.
If
set to AUTO, the input signal can be
monitored in Record Pause (Ready) mode, and the tape
signal while recording (off-tape monitoring)
or
playing.
The VU meters also switch the same way.
The 112
MK.II
does not provide off-tape monitoring ; you'll
hear the input signal instead while recording is taking place.
14. OUTPUT : Adjusts the signal level sent to the
OUTPUT jacks on the rear panel.
www.SteamPoweredRadio.Com
15. MPX FILTER : Por making Dolby recording
of
FM
broadcasts. Without this filter, the pilot tone (
19
Hz) and
subcarrier note (38 kHz) contained in FM programs may
"thwart" the DOLBY NR system.
16. DOLBY NR : Selects the Dolby B
or
C Noise
Reduction system or defeats them.
17. INPUTS, L and R : These 1/4"
jacks
accept
unbalanced line-level signals.
NOTE
Connecting signals to the front input jacks defeats the
rear input jacks. You cannot use both jacks at one
time.
18. PHONES: The knob adjusts the listening level
in
the
headphones plugged into the adjacent jack.
19. REPEAT : Initiates repeat play between Memo l and
Memo 2 (p.12)
20. MEMO
IN
:
If
pressed together with LOC l
or
2,
stores the current tape point into memory.
a MEMO
IN
cannot operate during repeat play
or
when
the tape is fast-winding as a result
of
pressing either
LOC.
21.
RTZ
: Fast-winds the tape at either direction, stopping
when the tape counter reads
00
00. Inertia may carry the
tape slightly past the
00
00 point.
22. LOC, 1 and 2 : Locate the tape to Memo I and
Memo 2 points, respectively.
23. DIRECTION (112R MKII only) : Switches over
the tape side to play
or
record.
a DIRECTION cannot operate during :
o Repeat play
o Search with LOC
or
CPS
o Fast cueing

end
or
beginning or whefl stop is pressed.
24. Auto Reverse (112R MKII only) : In one-time,
auto-reverse mode (
~
), both sides
of
the tape play or
record and stop. But, if play or record starts on the reverse
tape side, only that tape side plays or records and stops.
In continuous reverse mode (
c--.:>
),
the entire tape plays
up
to five times and stops, or both sides
of
the tape record
and stop.
25. ADJUST (122 MKIII only) :
If
pressed when
MONITOR is set to AUTO and the transport is in Record
mode, allows you to press the OSC and

High speed cueing functions (#4 and 5, page 6): Depending
on
some conditions such as type of
tape
in
use, environmental temperature and humidity, etc. reverse cueing may not possibly start, or may start
but not smoothly, if the current tape location is close to the beginning of the tape. Similarly, the forward cueing
may not possibly start as expected if attempted near the end of the tape.

Bias and Recording Level Calibration (122 MKIII only)
L BIAS R
L LEVEL R
0
Tapes differ considerably in the bias required to record on them and
in
their
sensitivity. The
122
MKIII allows fine adjustment
of
bias to exactly match the
tape being used ; also the reference recording level can be precisely adjusted to
compensate for difference
in
sensitivity among tapes.
■
Before starting adjustment, clean the heads, tape guides, rollers, etc. and
demagnetize the heads and all metal parts
in
the tape path.
■
In you intend to make adjustment while monitoring through speakers, turn
down their volume to avoid damage
to
them.
■
Have at hand a crisscross screwdriver which fits in with the BIAS/LEVEL
trimmers.
1 . Load the tape.
2. Make the following settings :
INPUT level controls to O ;
OUTPUT level control to O ;
MONITOR switch to AUTO ;
DOLBY NR switch to OFF ;
MPX FILTER to OFF.
3. Press
PLA V and RECORD to put the deck into Record mode.
4. Press
ADJUST. then press OSC.
5. Tum the BIAS trimmers all the way to the left with the appropriate screwdriver.
6. Slowly tum the
BIAS trimmers (one at time) clockwise for maximum reading
on the VU meters.
Suggestions :
Tum
the trimmers
to
the left and right alternately to "pinpoint"
the exact maximum position.
If
the meter needles deflect all the way to the
right, adjust the LEVEL trimmers until the meters read about
O VU at a
maximum setting
of
BIAS.
7. Adjust the
LEVEL trimmers (one at time) for O VU.
8. While alternating the oscillator signal between
IO
kHz and 400 Hz
by
pressing
the
10 kHz switch on and
off
(still
in
record mode), adjust the BIAS trimmers
so that the
VU
meters show almost the same reading at both frequencies.
9. Set the oscillator to 400 Hz (IO kHz LED off) and readjust the
LEVEL
trimmers for O VU.
Repeat the procedure each time you change the tape, especially when you change
the type
of
tape.

Dolby HX PRO
If
the source you are recording
is
rich
in
high-frequency
signals, they can adversely affect the accuracy
of
the
recording and decrease the high-frequency response. The
Dolby HX Pro system takes care
of
these signals during
recording to prevent the accuracy
of
the recording from
decreasing and improve the high-frequency response (by 6
dB
or more).
The Dolby HX Pro system uses no encoding/decoding
process and a cassette tape recorded with this system can be
played back on any stereo cassette player
s.
Care and Maintenance
D
Cleaning the Heads and Tape Guides
All heads and metal parts
in
the tape path must be cleaned
after every 6 hours
of
operation, or before starting and after
ending a recording session.
I . Open the cassette door.
2. Using a good head cleaning fluid and a cotton swab,
clean the heads and tape guides until the swab comes off
clean. Wipe
off
any excess ceaning fluid with a dry
swab.
D Cleaning the Pinch Roller
Clean the pinch roller at least once each day the deck
is
used. Use a good rubber cleancer.
I. Clean the pinch roller with a cotton swab moistened
with rubber cleaner, until there
is
no
visible residue on
the pinch roller
2. Using a clean cotton swab, wipe
off
all excess rubber
cleaner from the pinch roller. Make certain that there
is
no foreign matter remaining on the pinch roller.
D
Cleaning the Capstan Shaft
After cleaning the pinch roller, clean the capstan shaft with
a cotton swab moistened with head cleaning fluid.
