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)

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

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.
