Introduction

Optional Accessories

This manual covers the 122 MKIII, 112R MKII, and 112
MKII.
Your new TASCAM deck is a professional rack-mount 4­track, 2-channel recorder/reproducer designed to offer
outstanding audio performance and convenient features.

Speed in operation is, enhanced by CPS (Computomatic
Program Search) (112R MKII only), 2-point Autolocator,
and Retum-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 10 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 112R 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.

NOTE

Each time you turn on the deck, the last on/off status
of the ADJUST switch (122 MKIII only) and Auto
Reverse (CID / ZZD ) 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
normal 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

6. STOP : Stops all tape motion.

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.

11. INPUTS, L and R : Allow individual control of both

channel levels.

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 112R MKII; or 00
00 to 99 99 with the 112 MKII).

A type of tape in use (NORMAL, Cr02 or METAL) 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.

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 MKII 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.

15. MPX FILTER : For 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 1 and

Memo 2 (p.l2)

!CF DIRECTION cannot operate during :

O Repeat play

O Search with LOG or CPS

o Fast cueing
o 4-second blank recording

O” If pressed while in F.FWD or REW, switches the tape

side to play (or record) only when the tape reaches the
end or beginning or when 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 ( ctld ), 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 10 kHz switches
and to "fine tune" the BIAS and LEVEL settings. For more
details, see page 15.

20. MEMO IN ; If pressed together with LOG 1 or 2,

stores the current tape point into memory.

cr MEMO IN cannot operate during repeat play or when

the tape is fast-winding as a result of pressing either
LOG.

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 1 and

Memo 2 points, respectively.

23. DIRECTION (112R MKII only) : Switches over

the tape side to play or record.

Pressing26. OSC and 10 kHz (122 MKIII only)

OSC after ADJUST allows you to get 400 Hz or 10 kHz
oscillator signals for BIAS and LEVEL adjustments (you
get a 400 Hz signal unless you press the 10 kHz switch).

27. BIAS/LEVEL trimmers (122 MKIII only) : For

precise calibration of the bias/record levels to the tape being
used.

location, press F.FWD or REW.

4. Each time a blank space of about 4 seconds is encountered, the tape counter
display will decrement, and at the end of search operation, the tape will

automatically start playing.

■ Before pressing F.FWD or REW in step 3 if any of the following is pressed,

the function pressed is activated and the CPS mode is disabled ;

o Transport controls except F.FWD and REW
o RTZ
o LOC 1/2
o REPEAT

■ If you press F.FWD or REW after once search starts, the function pressed is

activated and the CPS mode is disabled.

■ In continuous reverse mode ( CZD ), you can skip to a selection on either tape

side.

In once-through reverse mode ( ), you can skip from the tape side facing
you to a selection on the reverse tape side, but you cannot skip from the reverse
tape side to a selection on the tape side facing you ; the tape will stop when
either end of the reverse tape side is reached.

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)

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 0 ;
OUTPUT level control to 0 ;
MONITOR switch to AUTO ;
DOLBY NR switch to OFF ;
MPX FILTER to OFF.

6. Slowly turn the BIAS trimmers (one at time) clockwise for maximum reading
on the VU meters.

Suggestions : Turn 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 0 VU at a
maximum setting of BIAS.

7. Adjust the LEVEL trimmers (one at time) for 0 VU.

8. While alternating the oscillator signal between 10 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 (10 kHz LED off) and readjust the LEVEL
trimmers for 0 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 players.

Care and Maintenance

A typical example of effect of Dolby HX Pro
(with Normal Tapes)

□ 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.

1. 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.

□ Cleaning the Pinch Roller

Clean the pinch roller at least once each day the deck is
used. Use a good rubber cleancer.

1. 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.
