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 oniy from the
forward to the reverse direction. For good sound quality and tc
avoid accidental erasure of previousiy recorded material,
always start recording with the side A of the tape facing out.
CAUTIONS
1. Prevention of Electric Shocks, Fire Hazards and Damage
1) Even when the POWER switch is set to STANDBY, a very
small current will flow. To save power and for safety when
not using the unit for an extended period of time, disconnect

sion)
2) Do not handle the power cord with wet hands.
3) When unplugging from the wall outlet, always grasp and pull
the plug, not the power cord.
4) Consult your nearest dealer when damage, disconnection, or
contact failure is found with the cord.
5) Do not bend the cord sharply, or pull or twist it.
6) Do not modify the power cord in any manner.
7) Do not remove screws to disassemble the unit and do not
touch anything inside the unit.

Procedure
1. Press the »» button during playback.
2. When more than 2 tunes are to be skipped, after procedure
1 press the PP (or <<) button the number of times you
want to skip tunes. The number of tunes to be skipped is
displayed in the counter.
* Relation between Multi Music Scan and REVERSE MODE.
= : The multi music scan mechanism operates on one
side of the tape only. If the number set is too high
(more than there are tunes remaining on that side),
the tape stops when the end of the tape is reached.
=) : It operates continuously through one cycle of the A
and B sides of the tape. If the number set has not
been reached, the tape stops at the end of the B
side. When the head rotates to play side A from B or
B from A, this rotation is counted as one non-
recorded section. When a recorded tune continues
from side A to B, this tune is recorded as two tunes.
In such a case, press the «++ (or »#;) button one
extra time.
Notes:
In the following cases, the mechanism may not operate cor-
rectly. This is not a malfunction; use the mechanism according
to the type of program.
* Tapes with tunes having long pianissimo passages (very quiet
parts) or non-recorded portions during tunes.
* Tapes with short non-recorded sections.

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, CrOz and metal), the adjustment
of INPUT LEVEL control is not required.
Read the instruction book of your CD player carefully.
COMPU CALIBRATION (COMPU CAL) FUNCTION
* This unit is equipped with a COMPU CAL function which can
automatically set the flat frequency characteristics and optimal
tape sensitivity for each tape in approximately 30 seconds.
Calibration data is retained for each tape type (Type I, Il or IV).
+ Calibration data set with COMPU CAL is retained even if the
power is turned off (or the power cord is unplugged), and the
previous calibration data for the same type of tape as the new
tape is recalled each time tapes are changed.
* Performing COMPU CAL operations again replaces existing
data with the new data.
COMPU CAL operation
* Insert the tape to be recorded and press the COMPU CAL but-
ton. During the operation, “C” -> “CA” -> “CAL” is displayed in
the tape counter. When the operation finishes, the tape returns
to its starting position, and the COMPU CAL indicator lights.
COMPU CALIBRATION is now finished.
* Pressing the IM (stop) button part-way will interrupt the opera-
tions.
* To recalibrate the unit, press the COMPU CAL button and wait
for the COMPU CAL indicator to go out. Then, press the
COMPU CAL button again.
Note:
If the tape is near its end, it will automatically stop and an error
will be generated during operation. Therefore, be sure to check
the time remaining on the tape (more than 2 minutes in the play
mode) before starting the operations.
COMPU CAL Errors
* When the COMPU CAL indicator flashes, this indicates a
COMPU CAL error.
* Press the M (stop) button to stop the error indication.
Care should be taken for the following items as they are the
cause of errors.
1) Dirty heads -Clean the heads.
2) Scratches on the tape surface
-Replace with an undamaged tape.
3) When the tape ends part-way through the operations
-Change the tape position.
4) In rare cases, tapes may have characteristics which fall out-
side the COMPU CAL setting range.
* When an error occurs or when COMPU CAL operations are
interrupted, calibration data cannot be stored in the memory. If
settings were previously performed, the previous setting val-
ues are retained.
- After confirming items 1) to 3) above and stopping the error
indication if there are no problems, even tapes which experi-
ence errors can be recorded on using either (1) the unit's pre-
set values or (2) previous setting values. (These are the values
obtained by opening and closing the cassette holder one time.)
* Preset value: a standard value corresponding to each type of
tape, which allows normal recording. (The pre-
set value condition is in effect when the
COMPU CAL indicator is unlit.)
Notes:
1. Since COMPU CAL operations record a test tone on tapes,
previously recorded contents will be erased.
2. Using new tapes and cleaning the heads beforehand are
recommended for optimal COMPU CAL operations.
3. Some variance in characteristics exists even with the same
type of tape made by the same manufacturer. Therefore,
when precise settings are desired, performing COMPU CAL
operations for each recording is recommended.
4. To delete contents set with COMPU CAL, simultaneously
press the @REC/REC MUTE and B deck COUNTER
RESET buttons. This deletes the calibration data for the type
of tape currently inserted in the unit. Calibration data for
other tape types is not deleted.
MICROPHONE MIXING DURING RECORDING
By connecting a microphone, microphone mixing during record-
ing is possible by foliowing the recording procedure. Adjust the
microphone input level by setting the record-pause mode and
observing the peak level indicators.
* When the record-pause mode is set and the INPUT LEVEL
control is set to MIN, sounds are output only from the micro-
phone, and it can be used as a public address system.
RECORDING LEVEL ADJUSTMENT
Adjust the recording leve! while observing the peak level indica-
tor indication.

* 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 eREC/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 eREC/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 eREC/REC MUTE button is pressed, press the
PLAY button before the unit enters the pause mode to start
recording again, or press the HPAUSE 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 ©, 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.
Note:
The sound quality will change if the positions of the DOLBY NR
switch are different in recording and playback.
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 Compu Link Control System controls relative operations
between components automatically and facilitates various
operations.
This ts 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-1/5YNCHRO” 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/Off (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 tumed 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
necessary to turn the deck (D POWER switch ON.)
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 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.
DDRP (Dynamics Detection Recording Processor) record-
in
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.
Notes:
- Synchronized recording or DDRP recording stops automati-
cally when the CD player stops playing.
* Synchronized recording does not start except when the record-
pause mode is set by simultaneously pressing the
e REC/REC MUTE and 11PAUSE buttons in the stop mode.
* To cancel synchronized recording or DDRP recording, press
the STOP button of the CD player or cassette deck.
- 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.

* Synchro record muting
When deck A stops or enters any mode other than the play-
back mode during dubbing, deck B enters the record mute
operation automatically and then enters the record-pause
mode.
* Before pressing the SYNCHRO DUBBING button
Confirm that deck B is in the stop mode betore starting dub-
bing.
Dubbing and DOLBY NR switch
During dubbing, the same NR mode selected for the playback
cassette is applied to the recording cassette, regardless of the
position of the NR switch.
Input level
Recording is performed at the same level as the playback tape
during dubbing regardless of the position of the INPUT LEVEL
control.
Microphone mixing during dubbing
By connecting a microphone, microphone mixing during dubbing
IS possible with the playback sounds from deck A. Be sure to
perform dubbing at normal speed. When performing microphone
mixing during dubbing, use cassettes recorded with NR OFF
mode for the deck A.
Tape editing
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 M (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 tum off
the television receiver or use the normal-speed dubbing
mode.
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 satisfactority.
+ recordings are not satisfactory.
Because of this, clean the heads, etc. every 10 hours of use so
that optimum recordings will be made.
Cleaning the heads, pinch roller and capstan
Wipe the heads, the capstan, etc. with a cotton swab with its tip
dipped in alcohol. For effective cleaning, use a cleaning kit avait-
able from your audio store. After cleaning, be sure that the
cleaning fluid has completely dried before loading a cassette.

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).
