2. Installation
1) Avoid placing the unit on or adjacent to an amplifier, to pre-
vent hum from being produced by some types of amplifiers.
Move the unit to a place not affected by the amplifier. Keep
the unit as far as possible from a TV set.
4) Do not store cassette tapes where there is a magnetic field
(e.g. near a TV, etc.) or in a place subject to high tempera-
tures or humidity.
2) Avoid installing the unit in a location subject to ambient tem-
peratures exceeding 40 °C (104 °F) (e.g. direct sunlight,
near heaters, etc.) or less than 0 °C (32 °F), excessive
humidity, dust or vibrations.
3) If this set is moved suddenly from a cold place (0 °C) to a
warm place, it may not function properly because of moisture
generated inside the unit. The unit will function properly
30 minutes after being moved.
5. Auto tape select mechanism (decks A and B)
This deck has an Auto Tape Select mechanism which distin-
guishes between different types of tape from holes in the
cassette. After the type of tape has been detected, bias and
equalization are set to be suitable for the tape.
•
Cassettes with the detection holes:
Metal tape (EQ: 70µs) ........................................ Type IV
CrO2 (chrome) tape (EQ: 70µs) .......................... Type II
•
Cassettes without the detection holes:
3. Cleaning the cabinet
Never use benzine or thinner for cabinet cleaning as they may
damage the surface finish.
Normal tape (EQ: 120µs) ..................................... Type I
Some earlier types of metal and CrO2 (chrome) tapes may
not be provided with the detection holes. Avoid using such
tapes, since correct equalization characteristics cannot be
obtained. Also do not use ferrochrome tapes whose charac-
teristics do not match this unit.
4. Cassette tape
1) Loose tape may become tangled in the tape transport
mechanism. Remove slack by winding the tape with a pen-
cil.

Turn the pencil to tighten the tape.
2) The use of C-120 (120 minutes turn around) or thinner tape
is not recommended, since characteristic deterioration may
occur.
3) To prevent recordings from being erased accidentally,
remove the tab(s) with a screwdriver. Reseal the slots with
adhesive tape to erase and re-record after the tabs have
been broken off.
6. Operations
1) Noise may be generated if the
switched OFF with the deck set to playback or recording
mode. Before switching the POWER switch OFF, confirm
that the (stop) button has been pressed. (B version)
2) Many operations of this unit are performed under the control
of a microcomputer. Use the unit only after carefully studying
the descriptions and cautions in each item. If operations are
done incorrectly, the unit may stop functioning correctly. If
this happens, for the J version, unplug the power cord and

Dolby HX PRO headroom extension
AUTOMATIC RECORD MUTING (DECK B)
When a source which contains many high-frequency compo-
nents is recorded, these high-frequency signals have the same
function as bias and therefore, the effective bias current
changes.
This facility is used to eliminate undesired sections and leave an
appropriate non-recorded section.
A. To leave non-recorded sections of about 4–5 seconds
automatically
This will result in phenomena such as changes in the level of
low-frequency signal and subsequent distortion and reduction of
the high-frequency saturation level.
1. When the undesired section comes during recording,
press the
REC/REC MUTE button and release it.
Dolby HX PRO headroom extension system controls the bias
current so that the effective bias is constant even when there
are fluctuations in the high-frequency components of the input
signal.
2. The REC indicator flashes and a non-recorded section is
made during record muting operation. About 4–5 sec-
onds later, the tape automatically stops, and the unit
enters the record-pause mode.
This greatly improves the high-frequency saturation level while
reducing the low-frequency signal level variations and distortion.
3. Press the PLAY button to start recording again.
•
The dynamic sound recorded with this system sounds the

This system automatically works when in recording; however,
1. Keep the
REC/REC MUTE button pressed continu-
•
ously as long as you want to make a non-recorded sec-
tion. By releasing the finger from the button after the
above operation, the unit enters the record-pause mode.
2. Press the PLAY button to start recording again.
Dolby HX PRO is not a noise reduction system.
COMPU LINK CONTROL SYSTEM
C. To leave non-recorded section of less than 4-seconds
When the undesired section comes during recording....
The Compu Link Control System controls relative operations
between components automatically and facilitates various
operations.
This is a system originated and developed by JVC for facilitating
various system operations. There are two versions of this sys-
tem; version 1 and 3. (For version 1 components, ‘‘COMPU
LINK-1/SYNCHRO’’ is marked on the rear panel. For version 3
components, ‘‘COMPU LINK-3/SYNCHRO’’ is marked on the
rear panel. This unit belongs to version 3.)
After the
REC/REC MUTE button is pressed, press the
PLAY button before the unit enters the pause mode to start
recording again, or press the PAUSE button to enter the
record-pause mode.
The peak level indicator lights even during record muting
according to the input level which can be heard from the
speakers or headphones so that recording can be resumed at
the exact point on the tape.
•
The version 3 system controls relative functions between this
unit and an amplifier or receiver, in addition to all of the functions
of version 1.
ERASING
When recording on a prerecorded tape, the previous recording
is automatically erased and only the new program is recorded
on the tape.
To erase a tape without making a new recording...
Follow the section ‘‘RECORDING’’ but in step 7, set the INPUT
LEVEL control to MIN.
Automatic Power On/STANDBY Function (COMPU LINK-3)
This function is available when an amplifier or receiver having a
COMPU LINK-3/SYNCHRO terminal is connected. For example,
if a deck contains a tape, the deck is turned on automatically
and the tape is played back by only pressing the PLAY button.
When the amplifier or receiver is switched STANDBY, the source
unit is automatically switched STANDBY. (In the B version, it is
DOLBY NR and DOLBY HX PRO
necessary to turn the deck
POWER switch ON.)
Dolby NR System
To reduce the hiss inherent in tape recording, use the Dolby NR

Synchronized Recording (COMPU LINK-1, 3)
Synchronized recording refers to the process in which the deck
starts recording in synchronism with the CD player. Perform the
synchronized recording as follows:
1. Set the cassette deck to the record-pause mode in accor-
dance with the recording procedures on page 8.
2. If you want the programmed recording, program the desired
tunes in any order you wish to hear.
3. Press the PLAY/PAUSE button of the CD player. By so
doing, the cassette deck is placed in the record mode and
synchronized with the CD player for recording. Synchronized
recording thus can be made possible.

Notes at dubbing
1. Normal-speed dubbing is recommended to obtain good
sound quality.
2. Television receivers placed close to the deck may cause
interference on the recorded signal when the deck is used in
the high-speed dubbing mode. If this happens, either turn off
the television receiver or use the normal-speed dubbing
mode.
