CAUTIONS

Prevention of Electric Shocks, Fire Hazards and Damage

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 the power cord from the household AC outlet.
Do not handle the power cord with wet hands.
When unplugging from the wall outlet, always grasp and pull the plug, not the power cord.
Consult your nearest dealer when damage, disconnection, or contact failure is found with the cord.
Do not bend the cord sharply, or pull or twist it.
Do not modify the power cord in any manner.
Do not remove screws to disassemble the unit and do not touch anything inside the unit.
Do not insert any metallic objects into the unit.
Unplug the power cord when there is a possibility of lightning.
If water gets inside the unit, unplug the power cord from the outlet and consult your dealer.
Do not block the ventilation holes of the unit so that heat can escape. Do not install the unit in a badly ventilated place.
Be sure to unplug the power cord from the outlet when going out or when the unit is not in use for an extended period.

Installation

Avoid placing the unit on or adjacent to an amplifier, to prevent 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.
Avoid installing the unit in a location subject to ambient temperatures exceeding 40 °C {104 °F) (e.g. direct sunlight, near heaters, etc.) or less than 0 °C (32 °F), excessive humidity, dust or vibrations.
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.

Cleaning the cabinet
Never use benzine or thinner for cabinet cleaning as they may damage the surface finish.

Cassette tape

Loose tape may become tangled in the tape transport mechanism. Remove slack by winding the tape with a pencil.
Turn the pencil to tighten the tape.
The use of C-120 (120 minutes turn around) or thinner tape is not recommended, since characteristic deterioration may occur.
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.
Do not store cassette tapes where there is a magnetic field (e.g. near a TV, etc.) or in a place subject to high temperatures or humidity.
Auto tape select mechanism (decks A and 8)
This deck has an Auto Tape Select mechanism which distinguishes 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:
- 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 ferrichrome tapes whose characteristics do not match this unit.

Operations

Noise may be generated if the power is on or in standby with the deck set to playback or recording mode. Before turning the power on or setting it to standby, confirm that the ■ (stop) button has been pressed.
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, turn off the power once, and then turn it on again, so that the unit can function correctly.

SELECTING THE AC SUPPLY VOLTAGE

When this deck is used in an area where the supply voltage is different from the preset voltage, reset the voltage selector to the correct position. Slide the voltage selector to the desired voltage with a screwdriver.

Cation:
Disconnect the supply cord before changing the voltage.

CONNECTIONS

Do not switch the power on until all the connections are completed.
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 Compu Link Control System version 3, do not connect the power cord to the SWITCHED AC OUTLET of an amplifier or receiver.

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.

Remote cable connection for COMPU LINK

By connecting a remote cable, COMPU LINK functions (automatic power on/STANDBY, automatic source selection, synchronized recording and DDRP recording) can be performed. In this time the provided pin-plug cords must be also connected.
When making synchronized recordings with a CD player, connect the remote cable to the COMPU LINK-3/SYNCHRO jacks.

Notes:

When making synchronized recordings, only a single deck should be connected to the amplifier.
If a component is not a JVC COMPU LINK component, bypass it when making the remote cable connections.
This deck can be connected with an amplifier and a CD player which have the COMPU LINK-1/SYNCHRO jacks for COM PU LINK performance. (See page 7 for details.)

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, the 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 side A of the tape facing out.

PLAYBACK

Playback of deck A

Operate in the order of the numbers m the 1llustrat1on.

Turn the power on.
Load a prerecorded cassette with side A facing out.
Select the side to be played back.
- Side A … Forward direction (PLAY )
- Side 8 … Reverse direction( PLAY)
Set the DOLBY NR to switch to the same setting as when the tape was recorded.
Select the REVERSE MODE switch as desired.
Press the PLAY button of deck A to start playback.
- When the deck contains a tape, the deck is turned on automatically and the tape is played back by only pressing the PLAY button.

Playback of deck B

Perform steps 2 to 6 of the above procedure for deck B.

Continuous play
First, set the REVERSE MODE switch to . Load cassette tapes in both decks and press the PLAY button of the deck to be played first for continuous play of both decks.

At this time, the CONT indicator lights in the multimode display. When the tape in the deck that plays first reaches the end of side B (in the reverse direction), it automatically switches to the forward direction and enters the standby mode. At the same time, the other deck starts playback. These operations continue 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.

Note:

Use tapes recorded using the same NR mode in decks A and B.

RECORDING

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.

Turn the power on.
Load a cassette for recording.
Set the DOLBY NR switch as required.
Set the REVERSE MODE switch as desired.
Select the side to be recorded.
Press the PAUSE button and the REC/REC MUTE button (record-pause mode). REC and indicators light.
Adjust the recording level. (See the right column.)
Press to “0000”.
Press the PLAY button to start 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 8), 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.

DDRP (Dynamics Detection Recording Processor) recording
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, CrO2 and metal), the adjustment of INPUT LEVEL control is not required. Read the instruction book for your CD player carefully.

RECORDING LEVEL ADJUSTMENT
Adjust the recording level while observing the peak level indicator indication.

For example: With metal tape

Because of the metal tape’s higher saturation level, it is OK that “+ 2” lights occasionally . With normal or chrome tape

It is OK that “+ O” lights occasionally.

When the recording level is too low, the hissing 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 distorted.
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 “O” 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.

To leave non-recorded sections of about 4-5 seconds automatically

When the undesired section comes during recording, press the REC/REC MUTE button and release it.
The REC indicator flashes and a non-recorded section is made during the record muting operation. About 4-5 seconds later, the tape automatically stops, and the unit enters the record-pause mode.
Press the PLAY button to start recording again.

To leave non-recorded sections of more than 4-5 seconds

Keep the REC/REC MUTE button pressed continuously as long as you want to make a non-recorded section. By releasing the finger from the button after the above operation, the unit enters the record-pause mode.
Press the PLAY button to start recording again.

To leave a 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 II PAUSE button to enter the record-pause mode.

The peak level indicator lights even during record muting according to the input level 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 7, 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 that contains many high-frequency components 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 is a system originated and developed by JVC for facilitating various system operations. There are two versions of this system; 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/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.

Automatic Source Selection (COMPU LINK-1, 3)
When the provided remote cables are used to connect this unit to other components that have COMPU LINK-1 or 3/SYNCHRO terminals, the switch-over of all system components is possible with a 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 activation 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:

Set the cassette deck to the record-pause mode by the recording procedures on page 6.
If you want the programmed recording, program the desired tunes in any order you wish to hear.
Press the PLAY/PAUSE button on 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) recording
The DDRP function makes possible fully automatic recording when used with a suitable JVC CD player. When the DDRP button of a suitable JVC CD player is pressed, the recording level is first adjusted automatically, then recording starts; it is not necessary to start recording by the normal procedure.

Notes:

Synchronized recording or DDRP recording stops automatically when the CD player stops playing.
To cancel synchronized recording or DDRP recording, press the STOP button of the CD player or cassette deck.
Synchronized recording does not start except when the record pause mode is set by simultaneously pressing the REC/REC MUTE and 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 components, cancel synchronized recording or DDRP recording first.
The INPUT LEVEL control does not function during DDRP recording.

DUBBING

Synchro dubbing
Operate in the order of the numbers in the illustration.

Turn the power on.
Load a prerecorded tape with side A facing out into deck A, and press the ◄I► (direction) button to select the travel direction.
Load the blank tape with side A facing out into deck B, and press the ◄ I► (direction) button to select the side to be recorded.
Select the REVERSE MODE.
Press to “00 00”. (Deck B)
Press the SYNCHRO DUBBING (NORM or HIGH SPEED) button to start dubbing.
Press the ■ (stop) button of deck B to stop dubbing.

When deck B stops, the dubbing mode is automatically released.

Synchro record muting
When deck A stops or enters any mode other than the playback 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 before starting dubbing.

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.

Tape editing

Press the e 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.
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.
Press the same SYNCHRO DUBBING button pressed before the pause again, and dubbing will start.

Notes at dubbing

Normal-speed dubbing is recommended to obtain good sound quality.
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.

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.

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 available 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 result 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 in contact with the tape every 20-30 hours of use with a head demagnetizer (available from your audio store).
