Connecting The Power Supply; Adjusting The 33 & 45 Rpm Speeds; Attaching The Ground Lead - Oracle Audio Delphi MkVI Gen-2 Owner's Manual

CONNECTING THE POWER SUPPLY


Plug the power supply output to the turntable input receptacle located to the rear of the turntable.

Plug the input cord to an AC outlet.
Note :
Keep the power supply away from signal carrying leads. The power supply can remain connected to the
wall outlet unless you don't intend to use the turntable for a long period of time.
ADJUSTING THE 33 & 45 RPM SPEEDS
Note : The 33 speed must always be calibrated first. The individual speed potentiometers are accessible from
the rear of the drive module. When viewing the module from the rear, a clockwise rotation of the potentiometer
will result in an increase of the selected speed. The inner circles of strobe marks on the calibrator disc are to be
used at 50 Hz. The set of strobe marks closer to the center are for the 33 RPM, the one next to it is for the 45
RPM. The outer strobe marks are to be used at 60 Hz. The outermost circle is for 45 RPM, the one next to it is
for 33 RPM. The use of incandescent or fluorescent lighting is required to accurately read the calibrator disc.
When the right speed has been reached the appropriate set of strobe marks will be standing still, with no back or
forth movement.

Place the calibrator disc over the spindle, on the platter.

Select the 33 speed and check for accuracy.

Insert the small screw driver supplied with the tool kit in the 33 hole at the rear of the drive module.

Rotate the 33 speed potentiometer, located to the left, when viewing the module from the rear, until the
strobe marks on the calibrator disc come to a standstill position. Rotate clockwise to increase the speed
and counterclockwise to reduce the speed.

Select the 45 speed and check for accuracy.

Insert the screw driver in the 45 hole and repeat the above procedure.

ATTACHING THE GROUND LEAD


Loosen the knurled nut from under the sub-chassis and insert one end of the groung lead.

Attach the other end of the lead to the ground post of your pre-amplifier.
