CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK,

DO NOT REMOVE COVER (OR BACK).

NO USER-SERVICEABLE PARTS INSIDE.

REFER SERVICING TO QUALIFIED SERVICE PERSONNEL.

This symbol is intended to alert the user to the presence of uninsulated “dangerous voltage” within the prod- uct’s enclosure that may be of suffi- cient magnitude to constitute a risk of electric shock to persons.

This symbol is intended to alert the user to the presence of important operating and maintenance (servicing) instructions in the literature accompa-nying the appliance.

* The graphical symbol are on the rear enclosure.

CAUTION:

TO PREVENT ELECTRIC SHOCK, DO NOT USE THIS

Digital Audio Tape

DAT (Digital Audio Tape) is a new recording system which digitalizes the audio signal and records it on a DAT cassette tape.

DAT records the audio signal by converting the analog sound into a digital signal. This converting system is called the PCM (Pulse Code Modulation), and its accurate processing of the audio signal allows recording/playback with lower wow and flutter, wider dynamic range, lower distortion rate, and superb signal-to-noise ratio. In addition, various control codes calls sub codes can be written on the DAT cassette separately from the audio signal. They are written for a variety of convenient playback/tape editing operations, and except for the absolute time, can be rewritten after audio signal recording has been completed.

Precautions

Features

On safety

• Operate the unit only on 120 V AC, 60 Hz.

• The unit is not disconnected from the AC power source (mains) as long as it is connected to the wall outlet, even if the unit itself has been turned off.

• Should any solid object or liquid fall into the cabinet, unplug the unit and have it checked by qualified personnel before operating it any further.

• Unplug the unit from the wall outlet if it is not to be used for an extended period of time. To disconnect the cord, pull it out by grasping the plug. Never pull the cord itself.

• AC power cord must be changed only at the qualified service shop.

Operation

Before making program source connections, be sure to unplug the unit.

Installation

Do not install the unit in a location near heat sources such as radiators or air ducts, or in a place subject to direct sunlight, excessive dust, mechanical vibration or shock.

Moisture Condensation

If the unit is brought directly from a cold to a warm location, moisture may condense inside the unit. In this condition, the tape may adhere to the head drum and be damaged, or the unit may not operate correctly. Always remove the cassette when the unit will not be used.

If moisture is present...

• Function controls will not operate.

• All operations will stop.

Serial copy management system (SCMS)

This unit utilizes the serial copy management system that permits digital-to-digital recording for one generation. You can record CD sound or other digital formats through a digital-to-digital connection. (See page 54.)

Three sampling frequencies

Recording/playback can be done with three sampling frequencies (48 kHz, 44.1 kHz and 32 kHz). 48 kHz: For analog and digital input signals in a standard mode.

44.1 kHz: For compact disc and pre-recorded DAT tape. 32 kHz: For analog input signals in a long-play mode.

Long play mode

This unit can operate in a long-play mode. Analog input signals can be recorded or playback for up to four consecutive hours when the DT-120 DAT cassette tape is used. The sampling frequency will be 32 kHz in the long-play mode.

Visible cassette loading

You can view the tape operation through the lid of the cassette compartment. Due to a revolutionary new transport mechanism, cassette loading time has been significantly reduced.

Excellent sound quality

1-bit A/D converter

For the A/D converter section which converts analog input signals to digital signals, the unit employs a 1-bit A/D converter which theoretically generates no zero-cross distortion for a clear, elegant sound quality.

Pulse D/A converter

Superior playback performance is achieved with a pulse D/A converter.

When the CAUTION indicator lights and the unit will not operate

Leave the unit turned on for about an hour.

NOTE

When closing the cassette compartment, do not push the cassette lid forcibly by hand, but perform with the 0OPEN/CLOSE button.

For the customers in the U.S.A.

For detailed safety precautions, see the “IMPORTANT SAFEGUARDS” leaflet.

If you have any question or problem concerning your unit, please consult your nearest Sony dealer.

Rich variety of subcode information

This unit can record subcode information such as Start IDs, program numbers, Skip IDs, and absolute time data, enabling you to quickly locate tunes and display the playback time in the same manner as when playing compact discs.

Post edit recording of sub codes

You can record or rewrite the following sub codes after the audio signal recording has been completed. Start ID: Signifies the beginning of a selection. Program number: Gives a number to the selection. Skip ID: Signifies the beginning of a portion to be skipped. End ID: Signifies the end position of recording/playback. Since sub codes are written on the tape separately from audio signals, the audio signals are not affected.

Installing Batteries ı

Notes on remote control

• Do not expose the remote sensor on the deck to strong light such as direct sunlight, lighting apparatus, etc.

• Do not place any obstructions between the remote commander and the remote sensor, or else operations will not be performed correctly.

• The controllable range is limited. Point the remote commander directly at the remote sensor on the deck.

• When remote control operation distance becomes shorter, the batteries are weak. Replace both batteries with new ones.

To avoid battery leakage

When the commander will not be used for a long period of time, remove the batteries to avoid damage caused by battery leakage and corrosion.

Battery life

About half a year of normal operation can be expected when using the Sony SUM-3 (NS) batteries.

2 LINE OUT (line output) jacks (phono

jack) Connect to the DAT or tape inputs of an amplifier. The playback signal of this deck will be output.

3 COAXIAL/OPTICAL DIGITAL IN (digital

4 OPTICAL DIGITAL OUT (digital output)

jack (optical jack) Connect to the digital inputs of an amplifier having a built-in D/A converter or another DAT deck, for playback of a DAT cassette or digital-to-digital recording.

Notes on connection

• Use the connecting cords specified in the illustrations.

• Turn off the power for all equipments before making connections.

• Be sure to insert the plugs firmly into the jacks. Loose connections may cause hum and noise. When unplugging, grasp the plug and not the cord.

Note on sound signals

When connecting an optical cable to the DIGITAL IN/DIGITAL OUT jacks, sound signals (L/R) are transmitted together through the cable.

Connecting Cords

There are following three types of

For LINE IN/OUT (analog input/ output) jacks Å

Use the supplied or an optional audio signal connecting cord such as RKC710HS, RK-C715HS, RK-C910ES, RKC915ES etc.

Note

Red plugs and jacks are for the right channel (R) and white ones for the left channel (L).

For COAXIAL IN (digital input) jacks

Use an optional coaxial connecting cord such as VMC-1ES, VMC-10ES etc.

For OPTICAL IN/OUT (optical transmission digital input/output) jacks Ç

Use an optional optical cable such as POC-15, POC-10HS etc.

]

How to connect the optical cable Î

Remove the cap and plug it in firmly.

Notes on the optical cable

• Do not bend the cord. When the cord is not used, curl it with a diameter of more than 15 cm (5 7/ inches).

• Do not use it under high temperatures.

• When the optical cable is not connected, cover the OPTICAL IN/OUT jacks with the supplied caps.
