Preliminary operations

Unpack the unit and all accessories. Please keep the packaging for future use
when transporting the device.
Remove the two transport lockings 8 by pressing them sidewards (fig. 1).
Fit the platter and depress the locking mechanism in its centre until it engages in
the groove of the platter spindle (fig. 2).
Insert the hinges 2 in the appropriate recesses (fig. 3).
Slide the cover 1 parallel to the position of the hinges 2 (opening angle
approximately 60°) until it locks in position. In this position, the cover can be
removed at any time.

Power supply

The delivered power supply will be connected to the socket 16. The mains set,
corresponding to the voltage indication on the nameplate has to be plugged in to a
power-supply plug either with 230V/50 Hz or 115 V/60 Hz on the primary side.
ENGLISH
Connection to amplifier or preamp

preamp (red or black RCA-type plug = right channel, white RCA-type plug = left
channel).
Connect Ground 15 to the ground connector of your amplifier or preamp.
Balancing the tonearm, setting tracking force
and antiskating
1. Switch off antiskating 9
2. Remove the stylus protection
3. Turn the tonearm counterbalance 3 on the tonearm (fig. 4). Unlock the
tonearm and move it over to the tonearm rest. Place the cue control lever 5 in
position. Hold the tonearm whilst doing so.
4. Balance the tonearm precisely by turning the counterbalance. The tonearm is
balanced precisely when it pivots freely.
5. Reposition the tonearm back on the tonearm support. Hold the tonearm
counterweight 3 and rotate the front wheel with the scale to „0" („0" is located
above the marking on the tubular tonearm section.) Now rotate the complete
counterweight in a counterclockwise direction and set the required tracking
force.
Set the appropriate value of the antiskating device 9 on the basis of the following
table:
Trackingforce 4
1 = 10 mN
= 12,5 mN
1,25
1,5 = 15 m
AT91 -> 2 = 20 mN
2,5 = 25 mN
3 = 30 mN
