OVERVIEW
Dear valued audiophile, thank you for choosing the ORACLE AUDIO SI 3000 integrated
amplifier !
The ORACLE AUDIO SI 3000 is one of the finest integrated amplifier available on the
market today capable of delivering such an outstanding level of realism, finesse and
refinement. The ORACLE AUDIO SI 3000 gives the true meaning to the reproduction of
recorded music with high fidelity and musicality.
Natural reproduction of recorded music is not only an elegant way to describe our
product, it is a feeling that captures your full attention from the very first moment you
experience the ORACLE AUDIO integrated amplifier. You can feel the subtlety and
nuances of the inner details, the lightness of touch within the music which you can only
feel at the concert hall. The ORACLE AUDIO SI 3000 has an extremely quick transient
response where every small micro dynamic signal is….distinctively there !
The SI 3000 delivers 300 watts at 8 Ohms and will power with a ease the most
demanding loudspeakers. This integrated amplifier was designed to include some unique
and very interesting features.

DESIGN PHILOSOPHY
Our goal was to stay as far as possible from flat surfaces as we wanted the ORACLE
SI 3000 to be as sculpturally and aesthetically as possible where comprise was never an
issue.
In the making of the SI 3000 chassis, financial considerations were never a limiting factor, as such issues should never be a limitation to artistic expression.
The chassis of the SI 3000 is an outstanding and unique work-of-art and a masterpiece of
mechanical engineering, specially crafted for people who want to express their
uniqueness. The extremely rigid chassis construction of the SI 3000 combines the use of
tow special magnesium aluminium alloys to minimize the effects that outside vibrations
have on the performance of an amplifier. The whole assembly is an impressive puzzle
specifically designed in a modular fashion similar to all previous Oracle products.
Through structural rigidity, mechanical coloration to the musical reproduction is very
significantly reduced. We applied our 20 years of experience in vibration control to
develop a very unique heat sink with absolutely no resonance.
The mechanical coupling to the playing environment of the SI 3000 is done through the
use of four adjustable threaded conical feet, made of delrin material for an optimal
mechanical filtering action.
The speaker outputs post are mounted at a 15deg. angle from vertical for maximum
flexibility in using any speaker cables available, the binding posts are the Rhodium Plated
by Cardas, chosen for both their sonic merits and manufacturing quality

OPERATION
1. SI 3000 INTEGRATED AMPLIFIER
VOL-DOWN BUTTON SELECTION
The VOL-DOWN button selection will reduce the volume
VOL-UP BUTTON SELECTION
The VOL_UP button selection will increase the volume
MUTE BUTTON SELECTION
When the MUTE BUTTON is selected is will bring the actual volume at 10%. To go back at the previous
volume, press a second time on the MUTE BUTTON or use VOL-UP or VOL-DOWN button selection.
TAPE_MON BUTTON
The TAPE_MON button selection has 2 functions. If the button is pressed then released, you will see the
word TAPE on the display and a led will light in the lower corner of th e
TAPE is indicated, but the TAPE-OUT outputs are always on the active inputs as before the TAPE_MON
was selected.
display. In this mode, the function
INPUT BUTTON SELECTION
Every time you press the INPUT button, you will switch to the following entry.

REMOTE CONTROL HANDSET
REMOTE CONTROL
The buttons selection on the remote control are similar
to the ones found on the SI 3000. The only difference is
with the selection of inputs. The button INPUT on the
remote control will reveal different inputs on the
display. If you choose one selection on the display, you
must press the button ENTER on the remote control. If
you don’t press on the ENTER button, the display will
erase after 2 seconds and you will keep the previous
active input selection. As for the buttons on the SI 3000
they will keep their functions exactly as they are
displayed.
The POWER button has 2 functions. First it will power up and shut down your SI 3000.
All of the circuits remains operational in all time.
In mode POWER OFF, the volume is simply put at 0 and the relays are deactivated.
If the user shuts down the SI 3000 with the POWER button, the display will be the same
as it was when the unit was shut down previously.

CAUTION
SI 3000 INTEGRATED AMPLIFIER
The ORACLE AUDIO SI 3000 is designed to operate at the right voltage line.
100, 120, 220, 230 V
If the voltage line requirement needs to be changed, this work must be accomplished by a
qualified Oracle Audio technician only.
It is recommended to unplug the AC power lead when you plan to leave the house for an
extended period of time.
Do not stack other devices directly on top, it is important to maintain proper ventilation
around the SI 3000. Improper heat dissipation from and around the SI 3000 could cause
overheating related problems.
Do not open the chassis without prior authorization from ORACLE AUDIO or from an
ORACLE AUDIO agent.
Unauthorized repair or tempering of any type will void the manufacturer’s warranty
