CONTENT
We developed this packing material so that your new Oracle Audio CD 2500 MK II player / CD
2000 transport is afforded maximum protection.
It consists of:
•A double layer cardboard box

important to preserve this packaging material since it is the only really safe method of
transporting your Oracle CD turntable.
The following items are located in the upper foam structure:
•4 suspension covers
•Magnetic disc clamp
•Aluminium top cover
•Oracle Power supply
•Suspension calibration tool
•Brilliance cleaner and lint free blue cloth
•AC power cord
•15 pin DC signal cord
•Remote control handset and batteries
The following items are located in the wooden module:
•1 CD turntable assembly
•1 plinth assembly including:
o4 suspensions towers
o1 display module assembly
•1 main CD turntable chassis assembly
•2 main chassis protective foam end caps
•1 main chassis hold down “C” shape foam spacer block

•Remove the wooden top cover using your Phillips screwdriver.
•Grasp the plastic protective bag at each end using the handles and lift the whole Oracle
player unit out of the box.
•Open the plastic bag at one end only and remove the foam protective end cap.
•Hold the plinth and slide the CD turntable assembly out of the bag.
•Remove the “C” shape, hold down spacer block.
•Remove the inner protective bag.
Note: Place the inner bag, the 2 protective end caps and the “C” shape hold down
spacer blocks back in the wooden box thus making sure they do not get lost. Put
the wooden top cover back up.
Note: When repackaging, it is important to use this inner protective bag to prevent
surface damage to the clear lacquer finish.

SUSPENSION FINE TUNING
Caution! Do not attempt to lift the main chassis from the suspension towers as this could
damage the connecting cable between the display module and the main chassis.
If the main chassis needs to be removed, a special technical document is
available from Oracle Audio Technologies or your local area distributor. This
work should always be carried out by an experienced and competent technician.
•Place your Oracle CD player on a flat surface to complete the set up procedure.
Suspension fin Tuning
The suspension of your Oracle CD turntable has been calibrated at the factory but it possibly
might require minor fine-tuning before putting the player into service. To help with this we have
supplied a suspension calibration tool to assist with accurate measurement and calibration of
each suspension tower.
Note: Before beginning this step, very carefully seat the aluminium top cover above the
compact disc in its specially machined recess and position, so that the two finger
slots match the one on the player main chassis. The slightly curved section of the
finger slots should be facing the front of the unit. This will give a more accurate
operational mass of the main chassis.
This picture indicates the target setting of the suspension system.
The tool supplied will help you determine if a suspension fine tuning is required. If no or only
minor changes need to be performed, you might select to leave the system as it is. At this point,
the suspension top covers can be installed and the player moved to its final playing location. To
complete the final leveling of the plinth, it will be necessary to use a spirit level. The leveling will
be achieved by adjusting the height of the threaded feet under the plinth.

Note: The reference to clockwise or counter-clockwise is determined by viewing the
spring module from above. To proceed with minor changes to the suspension fine
tuning, please read the following information.
Make the Suspension Housing Sit Lower
If the suspension housing is sitting to high as on this picture.
•With one hand apply a light down pressure to the main chassis while holding the
suspension housing.
•Rotate the spring counter-clockwise by very small increments until the suspension
housing lightly rests against the step on the gauge.
Make the Suspension Housing Sit Lower
If the suspension housing is sitting to low as on this picture.
•Gently raise the suspension housing with one hand.
•Using needle pliers, insert the tip of the pliers near the end of the spring and hold it firmly.
•While holding the spring to prevent it from turning, rotate by very small increments the
suspension housing, counter-clockwise. This will move the spring further out of the spring
calibration sleeve thus making the suspension housing sit higher.
Note: Do not allow the pliers to contact the aluminium parts since this could damage
the clear lacquer finish.
Important! In the unlikely event that your Oracle suspension system may need to be
completely re calibrated please refer to the caution on the preceding page.
•When all suspension towers are fine tuned, install the suspension covers.

CONNECTION PROCEDURE
The analogue and/or digital connections
CD 2000 Transport
Your Oracle CD transport is equipped with three digital outputs:
•BNC, (75 Ohms) output of 0,5 Volt peak to peak
•XLR, AES/EBU (110 Ohms), balanced output of 4 Volts peak to peak
•Optical, Hewlett Packard (ST, AT&T – glass) – Hp-HFBR 1412
Use the designed output to transfer the signal to your Digital to Analog converter.
Note: We strongly suggest the use of the best possible Digital/Optical Interconnect
cable available, your dealer will help you make the right choice.

Oracle Audio created a proprietary 2 IC chip circuit implementation of the balanced technology,
resulting in excellent audio performance. The fully-balanced technology offers a more open,
transparent sound with improved dynamics. The Oracle Audio balanced circuitry greatly reduces
transient demand on the component power supply, further improving signal integrity and noise
immunity.
Balanced audio interconnects utilize two conductors, while standard RCA audio interconnects use
only a single "unbalanced" conductor. This enhanced design gives balanced audio interconnects
the power to provide greater resistance against sources of noise (RF, EMI, etc.). The result is a
more pure signal transfer, especially in longer-run applications. The industry standard NEUTRIK

XLR connection is utilized due to their robust design and high performance. All internal wiring
consists of twisted shielded wire.
Your Oracle CD Player is equipped with:
•BNC, output of 0,5 Volts peak to peak @ 75 Ohms
•RCA analog output
•XLR balanced analog outputs
•Impedance < 100 Ohms
•Recommended impedance load 50 kOhms (Minimum 5 kOhms)
•Maximum effective output level, 2,4 Volts
•Digital to Analogue converter type, Delta Sigma
•Resolution 24 Bits
You now have a choice of analog connections. You might even consider running both at the
same time.
To utilize the analog RCA capabilities, connect your pair of RCA terminated interconnect cables
from the rear of the player to your preamplifier or integrated amplifier (CD INPUT).
To utilize the analog balanced XLR connections, connect your pair of XLR terminated
interconnect cables from the rear of the player to your preamplifier or integrated amplifier’s XLR
inputs.
Connection to the Pre-Amplifier, CD input
•Connect your pair of RCA terminated Analogue Interconnect cables from the rear of the
player to your pre-amplifier Digital input (CD input).
Note: It is not necessary to use digital output unless connecting to a separate stand
alone DAC.
Note: We strongly suggest the use of the best possible Analogue Interconnect
Simultaneous Connection of an External Digital to Analogue Converter
It is possible to simultaneously use the BNC (75 Ohms) Digital output to compare the players
internal Digital/Analogue converter, with that of an external (stand alone) D/A converter.
•Plug your digital/optical interconnect to the rear of the player and connect it to your stand
alone D/A converter.
•Connect the Analogue outputs to an “Auxiliary” input at the rear of your pre-amplifier.
•Balance the volume between the two D/A converters through the external converter
volume control…should this facility be available.
•Switch from “CD” to “Auxiliary” so as to compare the two options.
Warning! Lower the volume of the pre-amplifier as there could be a major difference in
gain, this could cause damage to your loudspeakers.
