Introduction
At
Jadis
, we are very proud to release a new
product after a lengthy period of
experimentation and trial.
Our
Jadis
amplifier is therefore the result of
long months of technical research and
countless hours of listening.
Enjoy your amplifier.
We thank you for your trust in our product.

Unpacking and checking
The
I-35
amplifier has been packed in a box that has been specially
designed for it. Do not throw away this box as it will be needed for re-packing
the unit when it has to be returned to the factory for maintenance or
upgrading. Please note that the warranty will be considered as cancelled if the
unit has been dispatched incorrectly packed.
The boxes should contain: The module of
I-35
integrated amplifier,
its tubes, the mains power cable and one 6-sided spanner which is used to
remove the covers of the units to allow the tubes to be changed
when necessary.

Description
Front View
On the front side of the integrated, you will find:
- The power switch ON/OFF.
- The Power led is green when the unit is turned on.
- The volume control, it adjusts the sound amplitude.
- The balance control. When you turn it, the sound is moving
from the left to the right channel.
- Source selector: Choose the source input.
On the back side of the amplifier, you will find:
- The RCA inputs:
- Two outputs connectors for each channel (left and right) to
speaker.
- The fuse (4A).
- The mains connectors.

Installation instructions
Read this carefully.
Optimum listening quality is obtained when the following
recommendations have been observed step by step.
1 - Each
I-35
intgrated amplifier unit is packed with its own tested
tubes. Place the tubes: be careful do not mix up the tubes and place them
immediately on to their corresponding place as indicated in the « Tube
position » .
2 - Place your Jadis amplifier on a flat, solid surface. Avoid placing
the units directly on a carpet or on inflammable material. Avoid placing
objects on top of the amplifier to ensure adequate ventilation.
3 - Because your Jadis is a tube amplifier, provide an open space to
allow a correct evacuation of heat. Do not try to cool your Jadis
amplifier with a fan or expose it to air currents: sudden cooling can
create microcracks on the tubes. Do not move your amplifier when the
tubes are hot.
4 - To ensure long term reliability the ON/OFF power switch must
be operated with a quick firm movement. Always use the ON/OFF Switch.
Never unplug the mains cord to turn off the unit. If it is necessary to change
a cable or to modify a connection, make sure the amplifier have been
switched off for at least five minutes before proceeding.

Tubes position
First of all, remove the grid which protects the tubes sockets (be sure
the mains connector is unplugged).
Attention: For mounting the tubes, do not force them, this may
damage the sockets. Be careful at dressing power tubes (A, B, C and D)
because they have stop pins on the central parts of the mounting base.
Mount first the regulator tubes ( 1, 2, 3, 4 and 5) then mount the
power tubes. The tubes placement is shown at the top of this page.
Replace the grid and never remove it when the amplifier is
connected to the mains voltage, whether it is running or not.

How to match your amplifier to your
loudspeakers
The load impedance is pre-adjusted in the factory for loudspeakers
from 4 to 8 ohms.
Nota: For a good listening level, choose loudspeakers with an
efficiency of more than 90 dB.
Internal adjustment of impedance:
Warning for connecting the speakers: This equipment reverse the
phase.

How to turn ON your amplifier
In order to get the best performance from your Jadis amplifier, it is
necessary to follow carefully the instructions below:
1- Check that the power switch is OFF.
2- Verify that the volume control is set to minimum.
3- Connect the loudspeaker wires to the red and black terminals
output at the back of the amplifier.
4 - Connect the interconnect cables between the sources and the
integrated amplifier input RCA connectors.
5 - Connect the mains cord of your amplifier which is detachable to
facilitate safer and easier moving of the unit. Always use the power cord
supplied or one of equivalent electrical rating. Insert the power cord into
its socket on the unit before plugging the other end to the mains network.
6 - Turn on the amplifier by setting the power switch to on.
7 - To change the source, be sure the volume is set to minimum before
turn the source selector.
Your Jadis integrated amplifier is now ready to play. However, its
optimum sound quality will be reached only when the amplifier reaches
its ideal temperature (after about 1/2 hour of operation).
Turn off your amplifier when you don't listen to it for a long time
(exemple: during the night).

Maintenance
Your Jadis amplifier is adjusted for a nominal voltage
corresponding to your country's electrical network.
If the integrated amplifier fails to operate:
1 - Turn OFF the unit immediately.
2 - Unplug all the cables.
3 - Do not forget the mains cord.
4 - Contact your Jadis dealer for diagnostic and repair.
To clean your amplifier, use a soft cloth with a non abrasive
cleaning product.
Do not forget to unplug all connectors before cleaning.
