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

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.
