INHALTSVERZEICHNIS

1. Auto-lift mechanism with non-contact record-end sensor

The automatic arm lift (auto-lift) mechanism functions in such a way that when a record playback is finished, the tonearm is automatically lifted and the turntable rotation stops. This eliminates worry about unexpected wear of the stylus by leaving record at play. At the end of play, a non-contact record-end sensor senses the velocity change of the tonearm with an opto-electronic transducer, eliminating unnecessary load on the record or stylus, consequently sound quality is not impaired.

2. Newly developed angular control motor for arm lift

The arm lifting device employs a servo controlled angular control motor newly developed by DENON, resulting in a smooth and silent up-and-down tonearm motion.

3. New material employed for base

Newly developed special compound, having larger specific mass and superior vibration damping characteristic than convention al aluminum diecasting is employed for the base. Direct sound pressure from speakers or vibration from floor are isolated and, thus acoustic feed-back is effectively eliminated.

4. Front panel operation provides more flexible operation

The operation buttons and controls are arranged outside the dust over. More over, the speed change-over, start/stop and up/down functions are electrically actuated allowing soft touch button controls.

5. Direct drive system featuring speed detection with magnetic recording and AC motor.

The turntable speed is detected by DENON's magnetic recording detection system having numerous features. An AC motor is employed which has less irregularity of torque and much smoother roatation than a DC motor. Superb wow / flutter and rumble characteristics and stable rotation under various load or external conditions have been accomplished. This is the excellent direct drive system DENON proudly presents.

CHARACTERISTIQUES

In order to use this record player in its optimum condition to perform its best, please read this instruction manual thoroughly and acquire full understanding of correct usage beforehand. For future reference in case of problems, be sure to retain this manual after you read.

ALTERNATION OF THE RATED VOLTAGE AND FREQUENCY

The rated voltage and frequency for your set correspond to the main's voltage and frequency used in the country to which it is shipped. (The rated voltage and frequency are shown on the rating label on the set.) If it is necessary to alter the rated voltage and /or the rated frequency, CONTACT YOUR DENON DEALER.

LISEZ CE MANUEL AVANT L'EMPLOI

1. Handle the detecting head and magnetic coating with care

The speed detection head is positioned with a very small gap to the magnetic coating surface. Do not for any reason loosen the attaching screws. Also be very careful not to scratch the magnetic coating surface when attaching or detaching the turntable platter to or from the motor shaft. Do not bring a magnet near the magnetic coating nor wipe it with solvent such as paint thinner, trichlene, toluene, or the pulse signal for speed detection will be disturbed and accurate speed cannot be expected.

2. When moving tonearm

To provide high performance, the tonearm of this record player consists of many prism parts. Avoid impacts or twisting. Especially in mounting or removing the head-shell, do not forcibly move the tonearm more than the swing range in up-and-down or rotational directions.

3. Take care of the turntable platter

Do not turn the power ON while the turntable platter is removed, nor forcibly stall the platter. Problems may result.

4. Select a suitable location

As much as possible, avoid locations where the turntable is exposed directly to the sun, or where it is moist or dusty. Place it on a horizontal position with little vibration. Ris also recommended to place the speakers and the record player away from each other.

5. No lubrication needed

The motor bearings of this record player are filled with special oil, requiring no further lubrication.

6. In your absence

When the set is to be left unused for a long time, be sure to remove the power supply cord from the wall outlet.

7. Avoid insecticides and chemically treated cloth

Avoid insecticides, benzine or paint thinner since they can discolor or deform the cabinet or dust cover. When removing dust, wipe with soft cloth (such as Silicone cloth). Avoid using a chemically treated cloth since it can discolor or remove the paint.

8. If dust is accumulated on the turntable mat, wash it away with water

PRECAUTIONS D'UTILISATION

Turns the power ON ( ) and OFF ( ).

(2) Speed selection button (Start button at the same time)

When this button is pressed, the speed is selected, the platter starts protation and at the same time the arm lifter lowers. Press buttons.

"33" for record at 33-1/3 rpm

"45" for record at 45 rpm.

(3) Speed control knob

Turn this knob left or right to vary speed.

(4) Strobe viewing window

Minitor flow of strobe pattern while adjusting the speed.

(5) Stop button

Press this button, and the arm lifter ascends and the motor stops. Because of inertia, the platter continues rotation for a while before it stops.

(6) Anti-skating knob

In playback of record, an attraction force toward inside of record is introduced at the stylus. This force is varied by adjustment of this knob. Refer to page (14) for adjustment.

(7) Counterweight

The stylus force applied to the cartridge is adjusted by this weight. Refer to page (14) for adjustment.

Do not connect power supply cord until the assembly is completed.

1. Mounting turntable platter

(1) Insert your fingers into the two holes of the turntable platter as shown in Fig. 1 and slowly mount on the motor shaft. For removing the turntable platter pull it up in the same way.
Note: The magnetic coating surface (inside part of the rim) must be handled with tare so as not to be injured.
(2) After mounting the turntable platter, place the turntable mat aligning the hole to the motor shaft.

2. Attaching counterweight

Push in the counterweight at the rear end of tonearm as shown in Fig. 2 with the stylus force scale facing front. While pushing the counterweight, turn it in the arrow direction. After attaching, make sure that it moves back and forth by turning it.

3. Mounting the cartridge

When mounting a cartridge on this record player, follow the instruction manual of the cartridge to be used as well as referring to Fig. 3 and following instruction.

Cartridges weighing 5g to 10g can be mounted with the use of the attached head shell. Be sure to protect the stylus from damage by leaving the stylus cover attached while mounting.

(1) Be sure to make correct connections. Follow the color coding on the lead wires (Fig. 3).
(2) When fixing the cartridge, at first, lightly fix it with screws so that it will move slightly. Adjust so that the head shell and the cartridge are in parallel and in right angle (Fig. 4).

Securely fix the screws after positioning the cartridge in the dimension shown in Fig. 5. At this position, a specified overhang can be obtained when mounted on the tonearm.

Note: When the cartridge is replaced, its weight will be different and so will be the stylus force. Be sure to adjust the stylus force, anti-skating and the aim lifter height.

It is easier if you replace cartridges readily mounted on a head shell than to replace cartridge alone. Therefore it is recommended to obtain a head shell together when you purchase another cartridge. The combined weight of 14g to 19g of the head shell and accessories is acceptable.

4. Attaching and detaching head shell on/from tonearm

(1) As shown in Fig. 6, align the guide pin with the slot at the tonearm end and insert.
(2) Turn the lock nut in the arrow direction in Fig. 6 until it stops and fix the head shell to the tonearm.
(3) For removing the head shell, turn the lock nut in the opposite direction of the arrow and gently pull it off.

5. Mounting dust cover

Hold the dust cover near the hinges by both hands as shown in Fig. 7 and push the "metal parts" of the hinges deep enough unto the "hinge catchers" of the cabinet.

For removing the dust cover, open it fully and pull it off in the same mariner.

HOW TO CONNECT

After assembly, make the following connections. Make correct and firm connections. Be sure that the power of amplifier is "off".

(1) Connect the L and R pin plugs of output cord to the L and R "phono" inputs of the amplifier to be used. (Fig. 8)
Also connect the Y-shaped lug of ground wire (combined with the output cord) to the "GND" terminal of the amplifier.
Note: Some cartridges may require a step-up transformer or a head amplifier depending on their type.
(2) Plug in the power supply cord to AC receptacle. (Or else, if AC outlet is provided on your amplifier connect the power supply cord thereto, referring to Fig. 8. Make sure at this time that the power capacity of the outlet is sufficient.)

ADJUSTMENT

1. Adjustment of stylus force

Set to the optimum stylus force for your cartridge as follows. If it is used with improper stylus force, mistracking or distorted sound may result. Use the cartridge always at optimum stylus force.

(1) Turn the power switch ON ( ).
(2) Press either "33" or "45" speed selection but-ton. Make sure the arm lifter is down and then turn OFF the power switch.
(3) Turn the anti-skating knob and set "0" to the reference line as in Fig. 9.
(4) Remove the stylus cover of the cartridge
(5) See Fig.10 and unlock the arm clamper. Hold the finger hook of the head shell (Fig. 6) with your fingers and remove the tonearm form the arm rest.
(6) Turn the counter weight to obtain horizontal balance as shown in Fig.11, taking your fingers off momentarily to check.

Note: Carefully and only momentarily remove your fingers to see the balance so that the stylus or tonearm will not be damaged.

(7) After the horizontal balance is obtained, return the tonearm to the arm rest and clamp it by the arm clampsper. Put the stylus cover as well.
(8) Then, being careful not to turn the counterweight, turn only the stylus force scale to bring "0" reading to the reference line. (This condition gives zero stylus force since the horizontal balance of the tonearm has been obtained.)
(9) Lastly, turn the counterweight in the arrow direction and bring the desired stylus force "2 (grams)", for example, on the scale ring to the reference line on the tonearm. (When the counterweight is turned, so is the stylus force scale ring. The number shows the stylus force in grams when turned in the arrow direction alter "0" balance. One division corresponds to 0.1 g.) Use whatever stylus force setting is recommended for your cartridge.

2. Adjustment of anti-skating

Turn the anti-skating knob and set the reading of scale to almost the same number as the stylus force. Read the scale at the reference line. Set to "2" on the reference line in the case of stylus force of 2 grams. (Fig. 12)

3. Adjustment of arm lifter

Adjust the height of arm lifter as follows. (Fig. 13)

(1) Turn the power switch ON (■) and press either of "33" or "45" speed selection buttons. Making sure the arm lifter is lowered, turn OFF (■) the power switch.
(2) Loosen the height fixing screw and let the arm lifter to the most lowerd position.
(3) Remove stylus cover, release clampper and place the tonearm over the record.
(4) With this condition, adjust the height of the arm lifter so that the gap between the arm lifter and the tonearm pipe is around 0.5 ~mm , and tighten the loosened screw.

Note: In order to avoid damaging the stylus, always put the stylus cover in place except when checking the gap by placing the stylus on the record.

HOW TO PLAY

Starting of play

(1) Turn the power switch ON ( ). The neon lamp in the strobe viewing window lights.
(2) Place a record on the platter, remove the stylus cover on the cartridge and release the arm clamper.
(3) Bring the tonearm over the desired position of the record and press either "33" or "45" speed selection button proper to the record. The indication lamp of the selected speed lights and at the same time, the turntable starts rotation and the stylus is lowered onto the record to start playing.
(4) When the last cut of one side is over, the stylus is automatically lifted off the record (auto-lift), and turntable rotation stops.

- Stopping play in the-middle

Press the stop button. The stylus is automatically lifted off the record and the turntable rotation stops.

- Adjustment of speed

Speed can be adjusted at both "33" and "45" by a single speed control knob. After lowering the stylus on the record, adjust the speed control knob so that the flow of strobe pattern in the strobe viweing window stops. The strobe patterns are lined up as in Fig. 14.

If the strobe pattern is flowing to the left (speed is fast), turn the speed control knob from left to right (to slow down speed), and if it is flowing to the right, turn it from right to left. This control knob changes speed more than ± 3% (Fig. 15)

Note: Even the strobe pattern stands still, it may flow a little, after a while. Since the neon lamp of this record player is lit by commercial power source, the strobe pattern flows if the power source frequency fluctuates even while the turntable speed is constant.

Note: The strobe pattern may sway a little front-and backward. This is because of eccentricity of strobe pattern and not the turntable platter. This causes no wow and flutter.

CAUTION: Do not make solder connections to cartridge terminals. Make all solder connections to terminal jacks

provided before slipping them over the terminals.

MONAURAL OPERATION: For monaural playback of records, the left and right channels should be connected in parallel. This is accomplished most conveniently by setting the function switch on the associated amplifier to "A+B" or "Mono."

SUGGESTIONS FOR CLEANING YOUR STYLUS : To clean the stylus, use a camel's-hair brush (No. 2 size or smaller) dipped lightly in alcohol or alcohol-water solution; grain alcohol is preferred. (WARNING: Commercial record or stylus cleaning solutions may cause corrosion and permanent stylus damage.) The alcohol will remove any sludge deposits which may have coated the stylus tip. The brush bristles should be trimmed to a length no longer than 14 inch. ALWAYS brush the stylus with a forward movement from the rear (terminal end of the cartridge) to the front. NEVER brush or wipe the stylus from front to back or side to side.

RECORD CLEANING: An effective way to clean a record is to immerse it in a solution of mild dishwashing liquid detergent and lukewarm or cool water (preferably distilled water). Use a lint-free cloth to work the mixture into the grooves, following the grooves around for a thorough cleansing. Then, rinse with clear, cool or lukewarm water (preferably distilled) and dry with a lint-free cloth.

EASY STYLUS REPLACEMENT

Grasp molded housing of stylus between thumb and forefinger. Gently withdraw stylus by pulling forward out of cartridge. Grasp replacement stylus between thumb and forefinger and insert into stylus socket. Press stylus into socket until molded housing of the stylus mates with the cartridge case. Care must be taken not to allow the finger to slip off the molded housing of the stylus, resulting in damage to the stylus tip or shank.

SPECIAL NOTE: The Dynetic stylus assembly used in these cartridges is the most critical component. To maintain the original performance standards of your cartridge, be certain that any replacement stylus you buy bears the following certification on the package: "This Stereo Dynetic stylus is precision manufactured by Shure Brothers Inc."
