. INSTALLING YOUR MIRACORD 50 H
1.1
You may support your MIRACORD on a standard base or mounting board designed for this purpose or make your own support in a cabinet or drawer. If you use the standard base or mounting board, the record changer can be easily mounted by slowly lowering the chassis and inserting the springs (in their sound and shock absorbing rubber supports) in the four holes provided. Follow the instructions on the enclosed template (17 452 9705), which gives you the exact size of the cutout necessary as well as the dimensions of the mounting holes. Using a screwdriver or coin, the lower threads of the screws 4 are now screwed clockwise through the bushes 1 so as to leave the plain, unthreaded part of the screws loose inside the bushes and the chassis free to move on the springs. This is the playing position of the unit.
1.11
After placing the mechanism in its support, make sure the record changer is free to move on its springs in all directions. Check the push-button operation to see that no parts bind on the wood board or base and that the lead wires are not drawn so tightly as to restrict the movement of the changer.
1.12
If it is necessary to transport or ship your MIRACORD after it has been installed, secure it to the base or
mounting board by means of the transport locks indicated on the template. This is done by tightening the screws 4 above the bushes 1 so that the chassis springs 6 are compressed and the chassis rests firmly on the bushes 1. Fasten the arm by means of the arm lock (Fig. 1–12, position red). The heavy cast turntable should always be packed separately and should never be shipped on the mechanism. Disconnect the unit before carrying out mounting works on the chassis.
1.2 Putting on the Turntable
Before putting on the turntable, move lever 21 with its associated spring (Fig. 2) sideways since it may be close to the cone bearing on which the turntable will be mounted. Make sure that the turntable is not placed inadvertently on the idler wheel. To do this, place the tone arm on its support and move the movable idler wheel inwards before putting on the turntable. Place the turntable on the cone of the turntable shaft. Do this carefully and gently, since otherwise the ball bearing might be damaged. Finally, put on the rubber mat making sure that the center hole is firmly pressed around the center raised portion of the heavy turntable. Center the metal cover plate (Fig. 1–5) on the rubber mat.
1.3 Installing your Cartridge
The standard accessories include the cartridge insert
Fig. 2
(Fig. 1-15) with the ELAC Stereo Magnetic Cartridge already mounted (Fig. 3). This insert should be pushed on to the tone arm (Fig. 1-7) up to the stop, whereby the cartridge terminals are automatically connected to the tone arm leads. The cartridge insert is best fitted with the arm horizontal.
1.31
Should a different cartridge be fitted, the correct procedure is as follows: The cartridge insert (Fig. 3A) contains a slide with two threaded holes to accept the cartridge. If the latter has its own bracket, this is secured with the aid of the threaded holes. If not, the cartridge itself is fitted to the insert, which is dimensioned to accept all cartridges with standard fixing holes. In mounting the cartridge be sure the stylus protrudes sufficiently below the lower edge of the cartridge insert to properly play either one or a stack of records. If the small spacers supplied do not give enough clearance, use the large spacers enclosed with the cartridge mounting hardware. The final position of the stylus (forward or backward) will be adjusted later (Par. 1.33).
1.32
The respective ground wires for each channel are connected to the terminals marked "O" adjacent to the R and L terminals.
The cartridge insert has four wires and requires no separate or fifth wire connected to ground. The proper connection of these four wires is shown in Fig. 4 (as shown with ELAC STS 344 cartridge). You can connect the
wires for either mono or stereo reproduction as shown. For stereo reproduction the R (right) channel should be connected to the R (right) pin on your cartridge and similarly the L (left channel) should be connected. For mono reproduction the two channels of a stereo cartridge may be connected in parallel or series.
1.33 Adjustment of the cartridge
There is an optimum position of the stylus with respect to the tone arm for every mechanism. If this optimum position is not used, tracking error will increase considerably. The MIRACORD 50 H is provided with a gauge which enables you to adjust the position of the cartridge after it has been installed and set it in the optimum position. This is done by means of the adjusting screw in the front of the cartridge insert (Fig. 5–17) and the gauge located on the chassis plate under the cartridge insert (Fig. 5-16). Turning the screw clockwise will move the entire cart-
ridge forward - counter-clockwise turns will move it backward. Set the position by lifting the gauge up to the stylus S itself (Fig. 5). If the stylus does not line up with the tip of the gauge, turn the adjusting screw until it is exactly in position. (For further description and explanation of this feature see Par. 3.3).
1.34 Stylus Landing Position on Record
Adjustment is made after having set the stylus force according to Par. 3.2.
Fig. 5
1.4 Installing the Counterbalance and Balancing the Arm 1.41
The counterbalance (Fig. 6–10) is installed by sliding it on to the rear of the tone arm as far as it will go. Then move it further by using the vernier adjusting knob 10 A (Fig. 6). The adjusting knob on the counterbalance should be on the right side and should be used to move the counterbalance forward and backward for either fine or coarse adjustments. The ratio of knob turns relative to movement of the counterbalance is designed to provide extremely accurate and precise adjustment of the arm balance.
1.42 Arm Lock
The arm may be locked in position for transport or to prevent accidental damage. A positive locking device is
Fig. 7
provided with clear indication of locked (red) and unlocked (green) positions (Fig. 7–12). If by chance an operating button is depressed while the arm is locked, a unique mechanism prevents damage to the mechanism while the changer automatically recycles and stops.
1.43 Balancing the arm (Arm lock [Fig. 7–12] in open [green] position)
After the cartridge has been installed and finally positioned, and the counterbalance has been inserted as above, you are ready to balance the arm. This is done with the stylus force adjustment dial (Fig. 7–9) set at zero. The hairline marking on the arm bearing (Fig. 7-9A) must now be lined up with the zero mark. Move the counterbalance backward or forward by means of the adjusting knob (Fig. 7–10A) until the tone arm is in perfect balance.
1.5 Setting Tracking Force
This force, which is the pressure the stylus exerts on the record, is easily set on MIRACORD 50 H by means of a direct reading dial (Fig. 8–9). It can be set for a minimum of 1/2 gram to 6 grams. Select the gram pressure recommended by the cartridge manufacturer. Then set the tracking force desired by turning the dial to the proper reading opposite the hairline on the bearing (Fig. 8–9A).
1.6 Anti-Skating Mechanism
Your MIRACORD 50 H incorporates a device to counteract the side force exerted on the stylus as it moves
toward the center of the record. While this force is extremely small, it can cause the needle to "skate" toward the center of the record at very low stylus forces, or introduce a very slight distortion due to unequal stylus pressure on the wall of the record groove.
1.61
Fig. 9 shows the operation of the anti-skating mechanism. The skating force exerted on the stylus is balanced by a counteracting force A. The value of the counteracting force can be varied by tightening a rotary spring with the aid of knob 8 and is transferred via a lever H to the bolt B on the tone arm shaft.
1.62
As revealed by thorough tests the force exerted on the stylus toward the center depends on the value of the stylus force. The anti-skating mechanism is designed in such a way that the skating force is compensated if the anti-skating knob (Fig. 8–8) is adjusted to the exact setting of the stylus force. For example: With 2 g stylus force set red point on knob 8 to position 2.
1.7 Amplifier Connections
The MIRACORD 50 H is provided with a 2-wire screened connecting lead which normally has a five-pin round plug
DIN 41524, but can also be supplied, on special order, with a one-pin coax plug for both channels. If it is intended to use the player with a stereo radio receiver or an amplifier with a low-sensitivity input and no equalization network, facilities are provided for inserting the PV 9 equalizer preamplifier under the chassis plate (see Par.6). The preamplifier incorporates the necessary equalizer network for compensating the recording characteristic. It must be ordered as an accessory and is supplied at extra cost. If no preamplifier is used, the terminals in the spring contact strip provided for it underneath the chassis are short-circuited by a shorting strip.
1.8. Mains Connections
The MIRACORD 50 H is supplied for connection to 110/ 115 V, 60 cps A.C. or 220/240 V, 50 cps A.C. The correct mains voltage and frequency are shown on the data plate under the turntable. Subsequent conversion to another voltage or frequency is possible by exchanging the motor with phase condenser respectively. When carrying out such a conversion, it must be borne in mind that the PV 9 preamplifier, if present, must also be adapted to the new voltage and/or frequency. Further details will be found in the Mounting Instructions for the PV 9 preamplifier (B 2–700 D E F).
Caution:
The heavy outer rotor of the hysteresis motor is secured for shipment by 2 plastic wedges. Be shure to remove these wedges before plugging the unit into the power socket.
2. OPERATING YOUR MIRACORD 50 I
2.1
Altough there are four different modes of operating your MIRACORD, depressing a single button is all that is necessary most of the time. These four modes are described in detail below, but before playing a record set the speed as described below, and release the arm by switching the arm lock (Fig. 11–12) to the green position.
2.11 Speed
Your MIRACORD 50 H is designed to operate at all four speeds (78, 45, 331/3, and 162/3 RPM). The speed is set with the lever at the extreme left (Fig. 1–2) and the speed selected is shown in the illuminated window (Fig. 1–18). It will only be illuminated when power is applied to the motor.
Note:
The hysteresis motor of the MIRACORD 50 H is designed to provide extremely accurate rotation of the turntable at the speed selected regardless of the line voltage, so that no further adjustment for speed is necessary.
2.2 Mode 1. Record Changer Operation
Use long Automatic Spindle SA 73 (10–6A) and insert the pointed end in the hollow center (6) of the turntable (Fig. 10–6). Automatic play is possible for either 7", 10" or 12" records. Up to 10 records of the same size can be played
Fig. 10 6A 6
in sequence. (For automatic play of 7" records with a large center hole, use accessory automatic spindle SA 383 [Fig. 12]). To start the record changer, lightly depress the button corresponding to the diameter of the records being played (i. e. for 12" records use the button marked 12). After the button is pushed, the turn-table will start turning, the first record will drop, and the arm will lift and lower the stylus gently onto the lead-in groove of the record. At the conclusion of the first record will drop, and the cord will drop, and the cord will drop, and the cycle will be repeated. At the conclusion of the last record in the stack, the arm will lift and return to the rest, the next record will a brake (Fig. 2–27) is applied to stop the turn-table.
Note:
To add records while the record changer is in automatic operation, be sure that at least one record is still on the Automatic Spindle. If there is no record on the spindle and an additional record is placed on the arm of the spindle, the mechanism will drop this record but will not play it. It will be necessary to depress the appropriate button again to play this record.
2.21
To remove the records after the last record has dropped and has been played, remove the "Automatic" Spindle from the shaft by lifting it up vertically and then remove the stack of records. This prevents undue wear on the center hole of the records.
Fig. 11
2.3 Mode 2. Automatic Single Record Operation
Use short spindle (Fig .1–19) (inserted point down). An individual record can be played automatically (without handling the arm) by using the small spindle and placing the record on the turntable, then lightly depress the button corresponding to the size of the record. The turntable will start rotating, the arm will lift, and the stylus will be gently lowered onto the lead-in groove of the record. At the conclusion of the record the arm will shut off and the brake will be actuated.
2.4 Mode 3. Manual Operation – Single Record
Use short spindle (point down). Manual operation of the MIRACORD 50 H is a very simple operation. Place the record on the short spindle as in 2.3 above, then lift the arm by means of the finger-grip and place it on the desired groove of the record. As soon as the arm is lifted the turntable will start rotating and the unit is ready to play. At the end of the record the arm will lift and return to rest and the mechanism will shut off, and the brake will be actuated.
Note:
As in all modes of operation, the arm may be lifted off the record at any time and returned to the rest or placed on another groove of the record without disturbing the mechanism.
2.5. Mode 4. Automatic Repeat Mode – Single Record Use short spindle ( inserted point up ). A record of any
size can be played over and over again by inserting the short spindle with the point up. The mechanism must be started by depressing the button corresponding to the size of the record being played. At the conclusion of the record the arm will lift and return to the start of the record and replay it. This will continue until the "Stop" button is depressed or the arm is lifted off the record manually and returned to the rest.

3. SPECIAL FEATURES OF THE MIRACORD 50 H
3.1 Cueing Device (Fig. 7–11)
Frequently it is desired to play a specific band of a record. This can be very simply accomplished with the Cueing Device (Fig. 7-11). This mechanism constists of a platform which supports the tone arm and stylus a short distance above the record when the Cueing Lever is moved forward (v). When the arm is moved by hand to the desired position so that the stylus is directly over the band to be played, moving the lever back will lower the stylus very slowly and gently onto the record ( v ). The arm can be lifted off the arm rest either by depressing the appropriate button (Par. 2.3) or by hand (Par. 2.4). The lever can be moved forward at any time, and will lift the stylus off the record and hold it at that point until moved by hand or by moving the lever back again. Do not move lever forward (lifting) when the tone arm is still locked.
3.2 Stylus Landing Position on Lead-in Groove of Record
This adjustment has already been made at the factory with an ELAC cartridge. If you have installed a different type of cartridge, a readjustment may be necessary. Connect the unit to A.C. power source (see Par. 1.8), set the desired speed of the turntable with the speed change lever (Fig. 1–2) and place a 7", 10" or 12" record on the turntable. Release the arm lock (Fig. 11–12) by switching
to the green position. Start the record changer by depressing the corresponding start button (7", 10" or 12"). The turntable will start to rotate, the tone arm will lift off its support and swing inwards and lower itself into the starting groove of the record. If necessary, correct the landing point of the stylus by turning slotted screw (24) (Fig. 6–24) on the tone arm socket. Turning screw clockwise moves the landing point outward, counter - clock wise—inward.
3.3 Stylus Position Adjustment
A very slight difference in the position of the stylus with respect to the tone arm bearing can result in a large increase in the error introduced in tracking. This is due to the fact that the arm is in a different position with respect to the record at the beginning of the record and at the end of the record. There is an optimum position which is determined by the geometry of the mechanism, depending on the length of the tone arm, the distance from the center of the record, etc. This optimum position has been carefully calculated for your MIRACORD 50 H. A gauge (Fig. 5–16) has been provided locating the exact point the stylus should be at for this optimum setting. To provide a means of moving the cartridge and stylus back and forth, a special mechanism has been built into the cartridge insert. The adjusting screw
(Fig. 5-17) moves the cartridge forward and backward laterally along the arm. When the stylus is positioned directly above the gauge, it is in its optimum position.
3.4 Stop Button (Fig. 11-13)
You will notice a fourth button on the chassis directly above the three operating buttons which are marked with the record size. This button is marked "Stop" and is used to interrupt the playing of a record or stack of records at any time. When depressing during play, it will lift the arm off the record and return it to the arm rest and shut off the mechanism. To resume play, you can depress the stop button again, and the record already on the turntable will be replayed. To drop the next record, it is necessary to depress the appropriate operating button.
3.5 The "Automatic" Spindle
The unsupported record spindle SA 73 for records with standard center hole represents a recognized breakthrough in the technique of record changing. It supports
your records in three places and provides for the most gentle dropping action ever devised for a record changer. For changing 7" records with 38 mm center hole, a special accessory, the SA 383 spindle (Fig. 12 and Par. 5.2) is available to order. This is exchanged for the SA 73 record spindle when required.
3.6 Freely Supported Chassis Suspension
The chassis rests on four soft cone shaped springs with plastic cups (Fig. 13) which have the important function of preventing acoustic feedback between the loudspeakers and the cartridge. The springs are packed with foam rubber in order to cancel oscillations caused by vibrations. The copper-plated spring, seated close to the push-buttons underneath the chassis is stronger than the three others so that the chassis rests in horizontal position. When shipping the unit, the installed chassis must be secured by additional screws to prevent it from moving sideways. Further details are to be found in the enclosed mounting board template.
4. MAINTENANCE
Your Studio Series MIRACORD is designed by the factory to require practically no lubrication during its life. Neither the motor nor turntable bearings should be lubricated, since they are provided with proper long life lubricants at the factory. Under extraordinary conditions where your unit has been subjected to extremes of dust and dryness, it is suggested that you have your local MIRACORD dealer service the unit.
Great care should be used any time the turntable is lifted off the mechanism and the idler wheel is exposed, to prevent oil or grease from reaching the rubber rim or inside rim of the turntable. If the idler wheel is noisy for any reason, a small drop of light machine oil may be care-
fully placed on the idler wheel bearing. Be sure to wipe off any excess oil from the rim with alcohol.
4.2
The needle of the pickup cartridge must always be free of dust. Diamond styli can be used for about 1000 hours of playing. However, despite their hardness, they abrade gradually. Worn needles impair sound reproduction and damage record grooves. The needle should be replaced in due time. A defective needle should be replaced immediately. Stylus exchange is an extremely simple matter, as shown by the example of the ELAC cartridge STS 344 (Fig. 3).
Should your MIRACORD 50 H require servicing, it is suggested that you call on your local MIRACORD dealer or ask him for the address of the nearest MIRACORD Service Station. If shipping the unit is required it is impor-
tant to use the original carton with the corresponding inserts to avoid shipping damage. The following hints are applicable for minor repairs:

6. ACCESSORIES
6.1 Stereo-Equalizer-Preamplifier PV 9
The interpolation of this transistor preamplifier, which simultaneously compensates the frequency response curve of the pickup cartridge for a medium recording characteristic, is necessary if the output voltage of the cartridge itself is not sufficient to drive the connected reproduction unit (amplifier) and is necessary, for instance, with nearly all radio sets and control amplifiers. When connecting MIRACORD 50 H to Hi-Fi-Stereo amplifiers with a special input for magnetic pickup cartridges of small sensitivity (3 mV), there is no need for

1. Einbau des Chassis
Man führt die Netzanschlußleitung und die Tonabnehmer-Anschlußleitung von innen durch das große Loch im Zargenboden unter Klemmblech und Isolierstück hindurch nach außen. Nun setzt man das Chassis ohne Plattenteller von oben in den Holzausschnitt ein, und zwar so, daß die Chassis-Federn mit ihren Kunststoff-Ansätzen in die Löcher K kommen (Fig. 1 b) und die Schrauben 4 genau über den Buchsen 1 stehen (Fig. 1).
Nun werden mit einem Schraubenzieher oder einer Münze das untere Gewinde der Schrauben 4 ganz durch die Buchsen 1 gedreht (im Uhrzeigersinn), so daß sich nun der gewindefreie Teil der Schrauben ohne Berührung innerhalb der Buchse befindet und das Chassis frei beweglich auf den Federn ruht. Dies ist die Arbeits- d.h. Spielstellung des Gerätes. Der Plattenteller kann nun aufgesetzt und das Gerät an das Netz und den Verstärker angeschlossen werden.
2. Transportsicherung
Man zieht den Netzstecker aus der Dose und nimmt den Plattenteller ab. Das Chassis wird mit der Hand fest gegen die Holzgrundplatte gepreßt, so daß die Chassisfedern zusammengedrückt werden. Dann dreht man mit Münze oder Schraubenzieher bei beiden Schrauben nacheinander das obere Gewinde bis zum Anschlag ein. Das Chassis sitzt nun fest auf der Grundplatte. Der schwere Plattenteller darf während des Transportes nicht aufgesetzt sein. Er muß gesondert verpackt werden.
3. Lösen der Transportsicherung
Vor Anschluß und Inbetriebnahme muß die Sicherung unbedingt gelöst werden, da sonst Rumpelstörungen auftreten. Man dreht (entgegen dem Uhrzeigersinn) den oberen Gewindeteil der Schrauben aus den Buchsen heraus, so daß sich das Chassis anhebt und nun wieder frei schwingend auf den Federn ruht. Danach wird der Plattenteller wieder aufgesetzt.

Instructions for Mounting the MIRACORD 50 H and MIRAPHON 22 H on Base AZ 6
The base contains the following parts for fixing the turntable, mains cord and pickup lead:
| 2 | Threaded bushes | 17 066 5190 | 1 | Cylindrical screw | 04 011 0054 |
|---|---|---|---|---|---|
| 2 | Nuts | 17 066 5191 | 1 | Washer | 04 341 0010 |
| 2 | Spring washers | 17 066 5205 | 1 | Clip | 11 098 5004 |
| 1 | Insulator | 11 098 5005 |
1. Mounting the chassis
Pass the mains cord and pickup leads through the cutout via the clip and insulator and out through the large hole in the base bottom. The chassis, without the turntable, can now be lowered into the cutout in such a way that the springs with their plastic extensions locate in the holes K (Fig. 1 b) and the screws 4 are exactly above the bushes 1 (Fig. 1).
Using a screwdriver or coin, the lower threads of the screws 4 are now screwed clockwise through the bushes 1 so as to leave the plain, unthreaded part of the screws loose inside the bushes and the chassis free to move on the springs. This is the playing position of the unit. The turntable can now be mounted in place and the necessary connections made to the mains and amplifier.
2. Transport lock
Remove the mains plug from the socket and take off the turntable. Press the chassis with the hand against the wooden base plate so as to compress the chassis springs. Then with a screwdriver or coin, tighten the upper threads of both screws up to the limit. The chassis is now firmly screwed to the base plate. The turntable must not be attached in transit, but should be packed separately.
3. Releasing the transport lock
Before connecting up and operating the record player, it is imperative for the transport lock to be released, otherwise reproduction will be affected by rumble. Unscrew the upper threads of the locking screws (counter-clockwise) out of the bushes, so that the chassis rests freely and resiliently on the springs. Finally, remount the turntable.
4. Detaching the chassis
Remove the mains plug and take off the turntable. Unscrew the lower threads of the locking screws out of the bushes and lift the chassis out of the cutout.
