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.  
(Fig. 2)  
CrO2 tape detection  
holes  
Metal tape detection holes  
Fig. 2  
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

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.  
2. Remote cable connection for COMPU LINK  
By connecting a remote cable, COMPU LINK functions (auto-  
matic power on/STANDBY, automatic source selection, syn-  
chronized recording and DDRP recording) can be performed.  
In this time the provided pin-plug cords must be also con-  
nected.  
When making synchronized recording with a CD player, con-  
nect the remote cable to the COMPU LINK-3/SYNCHRO  
jacks.  
When using the Compu Link Control System version 3, do not  
connect the power cord to the SWITCHED AC OUTLET of an  
amplifier or receiver. In the  
POWER switch ON. Otherwise, the automatic power on/  
STANDBY function cannot be carried out.  
B
version, turn the deck  
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 9 for details.)  
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.

forward direction and enters the standby mode. At the same  
time, the other deck starts playback. These operations con-  
tinue between decks A and B.  
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.

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.  
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.

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

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  
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.  
Note:  
The sound quality will change if the positions of the DOLBY NR  
switch are different in recording and playback.

nents is possible with simple one-touch of the source selector  
button of JVC’s amplifier or receiver.

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.
