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.
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
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.
3. Cleaning the cabinet

tures or humidity.
Auto tape select mechanism (decks A and B)
5.
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: 70ps) .........................................Type IV
Cr02 (chrome) tape (EQ: 70ps)
• Cassettes without the detection holes:
Normal tape (EQ: 120ps) .......................................Type I
Some earlier types of metal and CrQa (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 ferrichrome tapes whose charac
teristics do not match this unit.

CONNECTIONS
• Do not switch the power on until all the connections are com
pleted.
• Insert the plugs firmly, or poor contact will result, causing
noise.
• When the pin-plug cords are employed, always connect the
white plug to the left channel terminal. This helps to avoid
reversed connections.
• When using the Сотри Link Control System version 3, do not
connect the power cord to the SWITCHED AC OUTLET of an
amplifier or receiver.
1. Connection to a stereo amplifier
Note:
When installing the deck, be sure to install at a distance from
your amplifier. If they are stacked, noise (hum) may occur.
2. Remote cable connection for COMPU LINK
• By connecting a remote cable, COMPU LINK functions (auto
matic power on/STANDBY, automatic source selection,
synchronized recording and DDRP recording) can be per
formed. In this time the provided pin-plug cords must be also
connected.
• When making synchronized recording with a CD player, con
nect the remote cable to the COMPU LINK-3/SYNCHRO
jacks.
Notes:
1. When making synchronized recordings, only a single deck
should be connected to the amplifier.
2. If a component is not a JVC COMPU LINK component,
bypass it when making the remote cable connections.
3. This deck can be connected with an amplifier and a CD
player which have the COMPU LINK-1/SYNCHRO jacks for
COMPU LINK performance. (See page 7 for details.)

PLAYBACK
AUTO REVERSE OPERATION
The auto reverse operation of this unit turns the tape transport
over to the reverse of forward direction automatically when the
tape reaches its end during recording or playback.
• Because of cassette shell construction, a tape recorded in the
forward direction should be played back in the same direction
to obtain stable sound reproduction.
• During recording, auto reverse can be activated only from the
forward to the reverse direction. For good sound quality and to
avoid accidental erasure of previously recorded material,
always start recording with the side A of the tape facing out.
Playback of deck A
Operate in the order of the numbers in the illustration.
O Turn the power on.

• While one deck is playing back, the cassette in the other one
can be replaced. This is convenient for long-time playback of
background music.
Note:
• Use tapes recorded using the same NR mode in decks A and
B.
RECORDING
Notes:
• When the safety tabs are removed from a cassette tape, the
tape cannot be recorded even if you try. Make sure that both
tabs are still in place when performing full recording.
• When the tape is played or recorded in the reverse direction
(side B), only side B is played back or recorded and then the
tape stops automatically.
It may be unlawful to record or playback copyrighted material
without the consent of the copyright owner.
Deck B only
Operate in the order of the numbers in the illustration.
• Make sure the safety tab of the cassette has not been broken
off.
DDRP (Dynamics Detection Recording Processor) record
ing
DDRP recording is performed with suitable JVC CD players and
the recording level adjustment is performed automatically.
Since recording level adjustment is performed automatically for
different types of tape (normal, Cr02 and metal), the adjustment
of INPUT LEVEL control is not required.
Read the instruction book of your CD player carefully.
RECORDING LEVEL ADJUSTMENT
Adjust the recording level while observing the peak level indica
tor indication.
For example:
With metal tape
-30 20 15 12 10
L
Because of metal tape’s higher saturation level, it is OK that “+
2” lights occasionally.
With normal or chrome tape
6 -l-8dB
Turn the power on.
o
Load a cassette for recording.
o
Set the DOLBY NR switch as required.
o
Set the REVERSE MODE switch as desired.
o
Select the side to be recorded.
0
Press the II PAUSE button and #REC/REC MUTE button
0
(record-pause mode).
REG and II indicators light.
Adjust the recording level. (See the right column.)
o
Press to “00 00”.
0
Press the PLAY button to start recording.
0
n -30 20 15 12 10 8 6 ovu 2 0 2 4 6 + 8 dB
It is OK that “-f- 0” lights occasionally.
• When the recording level is too low, the hiss noise inherent in
the tape will be conspicuous.
• When the recording level is too high, exceeding the saturation
level, the recording will contain cracking noise and will be dis
torted.
• If “+ 4” lights too often because the recording level is too high,
the recorded sound may be distorted and seem to be breaking
up. If only “0” lights infrequently, the level is too low and the
recording may contain tape hiss.
It is best to adjust so that the maximum sound level of the
source to be recorded reaches the very limit of the saturation
level of the tape to be used.
The best level varies depending on the type of music and type
of tape so it is better to make a test recording, using FM music,
records, etc.

AUTOMATIC RECORD MUTING (DECK B)
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
1. When the undesired section comes during recording,
press the • REC/REC MUTE button and release it.
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.
3. Press the PLAY button to start recording again.
B. To leave non-recorded sections of more than 4-5 sec
onds
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.
C. To leave non-recorded section of less than 4-seconds
When the undesired section comes during recording....
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 llPAUSE 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.
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 O, set the INPUT
LEVEL control to MIN.
DOLBY NR and DOLBY HX PRO
Dolby NR System
To reduce the hiss inherent in tape recording, use the Dolby NR
System when making recordings. When listening to a tape
recorded with the Dolby NR System, set the DOLBY NR switch
to B or C according to the system selected in the recording
mode.
Dolby HX PRO headroom extension
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 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.
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.
This greatly improves the high-frequency saturation level while
reducing the low-frequency signal level variations and distortion.
• The dynamic sound recorded with this system sounds the
same even when the tape is played back in a deck that does
not have Dolby HX PRO.
• This system automatically works when in recording: however,
Dolby HX PRO is not a noise reduction system.
COMPU LINK CONTROL SYSTEM
The Сотри 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.)
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.
Automatic Power On/STANBY 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.
Note:
The sound quality will change if the positions of the DOLBY NR
switch are different in recording and playback.
-7-
Page 10
Automatic Source Selection (COMPU LINK-1, 3)
When the provided remote cables are used for connecting this
unit to other components which have COMPU LINK-1 or
3/SYNCHRO terminals, the switch-over of all system compo
nents is possible with simple one-touch of the source selector
button of JVC’s amplifier or receiver.
By doing this, the corresponding component will start playing
automatically.
The source select button of the remote control unit or the acti
vation button of the desired component can be also used for this
purpose. When the components have been switched over, the
previous component will stop playing within five seconds.
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 6.
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.
DDRP (Dynamics Detection Recording Processor) record
ing
The DDRP function makes possible fully automatic recording
when used with a suitable JVC CD player. When the DDRP but
ton of a suitable JVC CD player is pressed, the recording level
is first adjusted automatically, then recording starts; it is not nec
essary to start recording by the normal procedure.
DUBBING
* Synchro dubbing
Operate in the order of the numbers in the illustration.
Notes:
• Synchronized recording or DDRP recording stops automati
cally when the CD player stops playing.

• Synchronized recording does not start except when the recordpause mode is set by simultaneously pressing the
• REC/REC MUTE and II PAUSE buttons in the stop mode.
• The source is locked to the CD position during synchronized
recording or DDRP recording to avoid accidental stops or
switch-over to another component. To switch over the compo
nents, cancel synchronized recording or DDRP recording first.
• The INPUT LEVEL control does not function during DDRP
recording.

Tape editing
1. Press the #REC/REC MUTE button when finished dubbing
a tune. Deck B automatically enters the record muting mode
and leaves a non-recorded section of about 4-seconds then
enters the record-paused mode.
2. Press the ■ (stop) button of deck A and search for the next
tune you want by using the ◄◄ or PLAY button. Then
stop the cassette just before the beginning of the tune.
3. Press the same SYNCHRO DUBBING button pressed
before the pause again, and dubbing will start.
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.
Demagnetizing the heads
Magnetic objects brought close to the head or using the deck for
a long period of time, results in magnetization of the head, thus
noise occurs. When the noise is excessive, high frequencies on
the recorded tape may be erased.
Demagnetize the heads and other metal parts that come into
contact with the tape every 20-30 hours of use with a head
demagnetizer (available from your audio store).
Example: Deck B
MAINTENANCE
The importance of cleaning
When the tape is moving, magnetic powder and dust naturally
accumulate on the heads, capstan and pinch roller. When they
become too dirty.
• tone quality deteriorates.
• the output sound level drops.
• the previous sound is not erased satisfactorily.
• recordings are not satisfactory.
Because of this, clean the heads, etc. every 10 hours of use so
that optimum recordings will be made.
