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 called sub codes can be
written on the DAT cassette tape 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.

Features of DTC-700
Application of the serial copy management
system
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.
Three sampling frequencies
Recording/playback can be done with three sampling
frequencies (48 kHz, 44.1 kHz and 32 kHz).
48 kHz: For analog 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 played back 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
Newly developped 1-bit A/D converter (High Density Linear A/
D Converter) is provided for recording. Newly developped 1-bit
pulse D/A converter with excellent linearity is also provided for
playback.
Digital fade-in/fade-out
Professional sounding fade-in/fade-out of either digital or
analog signals can be accomplished by use of the FADER
button.
Post edit recording of sub codes
You can record or rewrite the following sub codes after the
audio signal recording has been completed.
Start 1D: 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.

Precautions
Operate the unit only on 120 V AC, 60 Hz.
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.
One blade of the plug is wider than the other for the purpose of safety and will fit into the power outlet only one way. If you are
unable to insert the plug fully into the outlet, contact your dealer.
CL
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.
¢ Do not place anything on the top of the cabinet. The top ventilation holes must be unobstructed for the proper operation of the
unit and to prolong the life of its components.
Moisture Condensation Po
If the unit is brought directly from a cold to a warm jocation, 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.
{f moisture is present...
e Function controls will not operate.
« All operations will stop.
When the CAUTION indicator lights and the unit will not operate
Leave the unit turned on for about an hour.
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.
