FOREWORD
We would first like to thank you, and this from the whole team at Oracle Audio,
for purchasing our Paris PH100 phono preamplifier !
This is your Paris PH100 Owner’s Manual. The following pages will describe the
key features, connectivity and safe operation of your new phono preamplifier. Although
some operations are self explanatory, we strongly suggest you read this booklet to
better understand the importance of the different key adjustments.

Features
Input / Output
There is one input ( R & L ) and one output ( R & L ) using RCA connectors.
RIAA Equalization
The RIAA circuit is designed by following the true RIAA standard.
The accuracy of RIAA standard curve is +/- 1dB.
Jumper-selectable gain setting
The Oracle Paris PH100 phono preamplifier has 3 gain settings. The gain must be
adapted to match your cartridge’s output with the input of your PH100 to provide an
optimal volume level and to prevent any overloading which would cause distortion.
Those settings are done by changing the position of a specific jumper as indicated in
the diagram on page 5 of this user manual.
The different gain levels are 41.5dB, 52dB or 62dB.
Jumper-selectable load impedance setting
The Oracle Paris PH100 phono preamplifier allows 5 different impedance settings. The
impedance is modified by changing the position of specific jumpers on each stereo
channel as indicated on the diagram on page 5.
-For MM phono cartridges (moving magnet) use the 47k Ohms load impedance
(standard).
-For MC phono cartidges (moving coil) you can choose an impedance of 100, 200, 511,
1k and 1.5K ohms.
Fixed value capacitance
-The 47k Ohms setting is coupled with a fixed capacitive charge of 150pF.
-There is no capacitive charge for the moving coil resistive load settings.
-The default factory gain setting is set at 41.5k with a resistive load of 1k Ohms.

Gain and Impedance setting
Moving Magnet (MM) cartridge gain & load setting:
Use the standard 47k Ohms impedance jumper setting on both channels
as shown in the diagram below with a gain of 41.5dB.
Moving coil (MC) cartridge gain & load setting:
Always follow the recommendations from your cartridge’s manufacturer to
determine whether to use the 100, 200, 511, 1K or 1.5K Ohm load
impedance setting. As a guideline, the phono cartridge output of 1,5mv to
2,5mv should use the 52dB. Phono cartridges with an output under 1,5mv
should use the 62dB gain setting.
IMPORTANT NOTE ABOUT JUMPER POSITIONING
1 ) ONE JUMPER MUST ALWAYS BE INSTALLED ON
ONE OF THE 3 "GAIN" JUMPER POSTS
2 )
THE SECOND JUMPER MUST BE INSTALLED ON
EITHER ONE OF THE 5M/C LOAD POSTS
OR ON THE M/M 47K ohms POSTS
3 )
FOR M/M 47K ohms SETTING ALWAYS
USE THE 41,5 db GAIN SHORTING POSTS
Gain 62 db
Gain 52 db
Gain 41.5 db

CONNECTION PROCEDURE
Ground connection
The knurled nut connection post between the INPUT and the OUTPUT is to be linked
with your tonearm / turntable’s ground lead.
Input RCA connectors
Connect the leads coming from your tonearm to the R & L “INPUT”of the PH100.
Note : The audio interconnect cables required for this connection are not included.
Output RCA connectors
Connect the RCA interconnect leads from the R & L “OUTPUT”of the PH100 to an
auxiliary INPUT of prepreamplifier or integrated preamplifier. Do not connect to a
turntable INPUT because this could be linked to an internal phono preamplifier section
of your integrated preamplifier.
Important note : The PH100 always has to be connected to an auxiliary input. Never
hook up the PH100 into a phono input on your amplifier or preamplifier.
AC Power
Connect of the supplied power cord to an AC wall outlet.

OPERATING INSTRUCTIONS
Operating your audio system should always be done by following an orderly ritual both
when powering it up or powering it down. We suggest you always begin by powering up
the phono preamplifier first followed by the pre-preamplifier then the preamplifier section
after a moment. Following this procedure will prevent hearing a loud thumping sound
generated by source components as they charge up their electronics. Powering down
your sound system should always be done by beginning with preamplifier, pre-
preamplifier to then finish with the phono preamplifier.
Always operate your Oracle PH100 phono preamplifier in a well ventilated area to avoid
overheating. Phono preamplifiers are very sensitive to their electromagnetic
environment and it is recommended to position your Paris PH100 as far as possible
from your preamplifier and other high voltage equipment or wires. Proximity to such
devices can create “HUM” noise. Such noise could definitely pollute the audio signal
noise and lessen the sonic performance of the Paris PH100 thus adversely impact your
musical experience.
