Set-up Instructions
This section describes how to assemble and install your Paris DAC250 converter. If you have any doubts
or difficulties with this procedure please contact your retailer who will know how to assist you. Open the
box and look that all the components listed in the “content section” are present.
Inside the box the Paris DAC250 is wrapped in a soft plastic bag to prevent damaging the piano lacquer
paint finish surface of the main chassis.
-Carefully remove your Paris DAC250 from the shipping box and protective foam. We suggest you
keep your packaging for future use since it has been optimized to protect your Paris DAC250.
-Level the unit on a solid shelf making sure there is sufficient ventilation all around the unit.
-Connect the audio interconnect cables (not supplied) to the preamplifier or integrated amplifier.
-Note that the Paris DAC250 can be connected with the RCA (unbalanced analog output) or with
the XLR analog output***.
-Connect the AC power cord supplied.
-The Master Switch of the unit is located on the back panel right next to the power cord connector.
Note*** : The Paris DAC250 exists in two different versions. In its unbalanced version the Paris DAC250
contains two fully discrete output analog modules and the XLR connectors in this case are simply there for
convenience as they carry the same signal as the one obtained from the two RCA connecteors at 2V
RMS. In its balanced version the Paris DAC250 is equiped with four fully discrete output analog modules
allowing a fully balanced operation mode in which case the output signal is of 4V RMS.

Using Your Paris DAC 250 as an external DAC for other digital sources
The Paris DAC250 features a 75ohm RCA digital input to convenitnetly be used as D/A converter for
external digital sources such as consumer DVD or Blu-Ray players, digital TV decoders or videogame
consoles. In order to switch your player to become a DAC and have the DAC250 use the digital input at
the rear as source of signal, pressing either IN UP or IN DOWN on your remote control will toggle to the
digital input or CD modes. The Paris DAC250 also features a 75ohm coaxial digital output for eventual
connection to an external digital/analog converters.

Remote control
-Top right button is for the “STANDBY” function.
-The numbers allow selecting a specific track of the disc.
-The “L” and “R” buttons will allow shifting the channel balance.
-The “VOLUME” buttons will vary the playing level from 0dB to minus 80dB. This can be
particularily useful if you would like to connect you analogue output directly to the amplifier
“BYPASS” or the power amplifier “INPUT”. The system’s volume is then controled through the
Paris remote control volume buttons. If you are using your Paris DAC250 through a
preamplifier or integrated amplifier input make sure you keep the volume set at 0dB!
-The “MUTE” button is used to mute the sound of your Paris DAC250. Press again to un-mute.
-The “DISP” is used to turn the front panel display ON or OFF as a toggle.
-The “SHIFT” button is used to sychronise your remote to your Oracle product. To sychronise the
remote for your CD press the “CD” button, release it, and then follow by pressing the “SHIFT”
button.
-The 6 CD control buttons operate the DAC250 exactly ike the buttons on the front panel.
-The “RPT” is not present on the front panel. It is used to set the CD your are playing to repeat the
track or repeat the whole CD.
-The F1, F2, F3 and F4 functions are not used for the CD player operation.
Connecting your Paris DAC250 DIRECTLY to the
amplifier input
The possible application of this is to favor using the DAC250 as your pre-amplifier. It is possible to connect
the DAC250 directly to the inputs of your power amplifier completely bypassing your preamplifier. The
volume control in this situation is entirely provided by the DAC250’s remote control. Such a connectivity is
possible for integrated amplifiers that are equiped with a “BYPASS” mode.
Important note: If you decide to do such connection make sure that you have lowered the volume of your
Paris DAC250 to about –40dB prior to connecting it to your amplifier. Furthermore, make sure the
amplifier is turned OFF prior to conencting your Paris DAC250 to the RCA or XLR inputs.
Explanation : In some applications we have found that we will get a better overall sound if we connect the
Paris DAC250 directly to the amplifier inputs or BYPASS inputs from an integrated amplifer. The reason is
simple: if the performance of your preamplifier is not the best available it is very possible that you would
gain substantially in sound performance by using this method. We invite you to experiment CAREFULLY
with this if your equipement allows it.
