GETTING STARTED

Thank you for purchasing the music hall mmf-mark 1 turntable. It is a 2-speed belt-driven, audiophile turntable that comes complete with an Ortofon cartridge mounted in a high-quality aluminum tonearm. The alloy platter runs on a precision, stainless steel, and brass bearing assembly to provide a fluid and quiet operation. These features combine to ensure that the MMF-mark 1 delivers a superior audio performance that will provide years of enjoyment.

FOR YOUR INFORMATION

This manual provides valuable information that will help you get optimum performance from your system. Please contact your authorized music hall dealer for any additional clarifications you may require. Save the music hall mmf- mark 1 shipping carton and all enclosed packing material for future use. Shipping or moving the mmf-mark 1 in anything other than the original packing material may result in severe damage that is not covered by the warranty. Be sure to keep the original sales receipt; it is your best record of the date of purchase, which you will need in the event warranty service is required.

SET-UP
The music hall mmf-mark 1 is supplied partially assembled and carefully packaged for safe transport. To assemble the turntable, please follow the instructions carefully.

1. Clear a level (use a spirit level) and suitable workspace to assemble the turntable. This may be the final playing location.

2. Remove the turntable and all parts from the carton.

3. Install the drive belt (7) for 33 ½ and 45 rpm play. For 33 rpm, loop the belt around the smaller diameter rim of the stepped motor pulley (8) and around the rim of the sub-platter (9). Change the speed to 45rpm by moving the belt around the larger diameter rim of the stepped motor pulley (8) and around the rim of the sub-platter (9).
   

4. Center the platter (1) over the spindle of the sub-platter (9) and lower it until it rests securely on the sub-platter.

5. Find the counterweight (3). It is in a cut-out in the bottom piece of packing foam. Place the counterweight (3) onto the tonearm. To do this, you are positioned in front of the turntable. Orient the counterweight so that the counterweight number (no. 82) is in the back. Carefully, move the counterweight onto the back of the counterweight support rod. Don’t worry about the exact position of the counterweight or the tracking force scale, they will soon be adjusted.

6. Remove the tonearm-locking strap. Place it in a safe position for possible future transport.

7. Make sure the tonearm is in the tonearm rest (5). Carefully, remove the stylus guard (the piece of clear plastic on the bottom of the cartridge). Place it in a safe place for future use.

8. You will now set the cartridge tracking force. The MMF-mark 1 comes complete with a factory-installed Ortofon cartridge. We recommend a tracking force of 1.8g.
   Before setting the Vertical Tracking Force, confirm the exact weight of your cartridge.
   Pushing carefully, move the counterweight onto the rear end of the counterweight support rod as shown in the illustration below. Place the stylus pressure gauge onto the platter. To set the required VTF, lower the tonearm lift lever as indicated in the illustration and place the tip of the stylus exactly in between the two points marked 15mN and 20mN. If the stylus gauge becomes level, then the correct pressure has been achieved. However, if there is insufficient or excessive pressure the gauge will either not move or tilt down.
   To adjust the amount of pressure, carefully move the counterweight (3) along the support rod, until the stylus pressure is sufficient to raise the pressure gauge to the level position. Moving the counterweight (3) away from the cartridge will reduce pressure and will increase pressure. Finally, secure the counterweight (3) using the hexagonal key provided.

9. The anti-skating force must be adjusted corresponding to the tracking force. The anti-skating mechanism is calibrated from O to 5g. The anti-skating force should correspond with the tracking force.
   Three examples of magnetic anti-skating mechanisms:
   a) Tracking force – 1,5g; Anti-skating force 1,5g
   b) Tracking force-1,7g; Anti-skating force 1,7g
   c) Tracking force – 2,3g; Anti-skating force 2,3g

10. Slide the dust cover (17) onto the dust cover hinges (13) on the back of the plinth. If necessary, adjust the tightness of the hinges by turning the dust cover hinge screws (14).

NOTE
If you are substituting another cartridge for Ortofon OM NN, you may need to make the following further adjustments to the tonearm (2) and cartridge:

If you are a novice, music hall recommends getting professional help.
All cartridges with half-inch mounting holes can be fitted. Leaving the stylus guard on, fit the cartridge to the headshell (10) using the screws supplied with the cartridge by passing one screw through each slot in the finger lift and the headshell (10). Snug the nuts.

Connect the tonearm (2) wires to the cartridge pins as follows:
white left channel positive (L +) red
right channel pos. (R+)
green right channel return (R -)
blue left channel return (L -)

To achieve the best sound reproduction, the cartridge must be positioned precisely in the headshell. To do this, fit the tangency guide (you’ll find this in the parts bag . It’s a white rectangular piece of cardboard with black lines) over the spindle at point ‘A’ and onto the platter, black lines side up (See diagram below). Remove the stylus guard. Move the tonearm (2) (adjusted for the correct tracking force of your cartridge) to the pattern. When the stylus tip of the cartridge is at two points shown on the guide, the front of the cartridge should be parallel to the lines on the pattern. If necessary, slide the cartridge back and forth until the stylus tip is positioned correctly. Tighten the cartridge mounting screws.

VTA Adjustment: The VTA for the installed Ortofon cartridge has been properly set at the factory. To adjust the VTA for other cartridges, lay a record on the platter (1 ). Slacken the horizontal adjustment screws (two Allen screws located near the plinth on the back of the tonearm pillar) with the Allen Key provided.

IMPORTANT

Do not loosen the vertical screws that hold the tonearm to the base. Move the tonearm (2) up or down until it is parallel to the record surface when viewed from the side. Tighten the horizontal adjustment screws. VTA like Tracking Force can also be set by ear. Feel free to experiment with VTA positions slightly above or below parallel and choose the position you prefer. If you have any further questions regarding the adjustment of your turntable, please contact your music hall dealer.
*Save all packing materials, parts, and screws for possible future transport.

SITING
FLOOR MOUNTING – Place the deck on a small, light, rigid table, e.g., a coffee table. Ensure that the table is level on the floor and not rocking.
WALL MOUNTING – Wall mounting may be preferable when the floor is springy or when there is a risk of damage by children or pets. The shelf should be light and rigid, and fully supported by, but not firmly screwed or glued to its brackets.
To allow the lid to open fully, a clearance of 3 inches (7.5 cm.) is required behind the plinth and at least 13 inches (33 cm.) above.

MAINS CONNECTION

Locate the wall transformer. It’s in a small white box set into the underside of the packing foam. Plug the small male end of the wall transformer wire into the female receptacle on the DC power input (16) for the motor. The DC power input socket (16) for the motor is located on the underside of the turntable near the back. Plug the transformer into the wall. Turn the motor ‘ON’ (11) and check that the platter (1) spins.
AUDIO CONNECTION
The supplied Ortofon cartridge is a moving-magnet cartridge. Connect the interconnect cable and ground cable to the MM (Moving Magnet) phone input on your receiver, integrated amp, or pre-amplifier.

OPERATION

Place a record on the platter and push the mains switch (11) to the ‘ON’ position. Remove the stylus guard and lift up the tonearm with the cueing lever (6). Position the cartridge stylus tip above the initial groove of the record. Gently lower the cueing lever (6) to drop the arm onto the record.
To stop play, lift the cueing lever (6) to raise the arm and then bring the tonearm back to the tonearm rest (5). Push the mains switch (11) to ‘OFF’.
It is recommended to replace the stylus guard (optional) when the turntable is not in use.

MAINTENANCE

The MMF-mark 1 is designed for long operational life. To preserve the appearance of your deck and maintain its performance, you should note the following points when cleaning (Make sure the stylus guard is in place before you begin):
PLINTH – The plinth is constructed from medium-density fiberboard, therefore it should not be subjected to extremes of temperature or direct sunlight. The finish may change slightly with age. A damp cloth or soft duster is ideal for cleaning the plinth; polish, particularly wax-based, can be hard to remove.
PLATTER – The alloy platter can be cleaned with a soft, dry, lint-free cloth .
MAT – Clean the felt mat with masking tape.
MOTOR – The motor is equipped with self-lubricating bearings. The motor pulley should l;>e cleaned periodically to remove deposits of rubber shed by the belt.
Remove the outer platter and belt. Gently clean with a cotton swab or lint- free cloth dampened with isopropyl alcohol.
BELT – The belt should last for many years. The belt can be cleaned at the same time as the pulley. The best way to clean the belt is to pull it gently through a damp cloth. If the turntable is not going to be used for a long period of time, it is advisable to remove the belt from the platter rim to prevent stretching.
OIL – The oil supplied for the main bearing provides life-long protection. If oil is lost from the bearing housing, replace it with a single drop of Mobil 1 or other 1 0w/40 synthetic oil containing Teflon.
DUST COVER – This can be cleaned using any commercial acrylic or plastic cleaners. The simplest approach is to remove any dust with a damp, lint-free cloth without rubbing and then use a soft duster. Covers are more often damaged in cleaning than in use.
STYLUS – Remove the stylus guard. We recommend a dry, vibrating-pad cleaner. Wet cleaners or soft stylus brushes are not recommended.
