OWNERS MANUAL
First may we thank you for choosing a valve amplifier from
A.R.I.A. Advanced Research In Audio srl.
Your new amplifier is the result of many years of electronic
design experience allied to a thorough understanding of
electronic tubes. But more than that it is the fruit of our
passion, and of our wish to create products to give musical
enjoyment and lasting value, in which the traditional
craftsman’s skill is blended with advanced electronic design.
Each and very one of our products is built using the best and
most trusted materials, before being subjected to rigorous
testing and final inspection.
All the wood parts are hand made in solid wood by expert
craftsmen, and finished exclusively with natural organic
lacquers. As well giving a very pleasing appearance to the eye,
the wood also benefits sound quality by helping to dampen
resonance in the metal chassis .
UNPACKING
First of all please make sure that the carton is scaled and that
the amplifier has not suffered any damage in transit. If you
notice any signs of damage, consult your Authorised Dealer
before attempting to operate the unit.
To protect delicate parts against shocks during transport, valves
are normally packed separately.
Please refer to the fitting instructions for valves contained in
this manual .

IMPORTANT !
When unpacking an amplifier which is cold, allow it to
stand for sufficient time to reach normal room temperature
before attempting to operate it. This precaution will allow
any condensation which may have formed on the electronic
parts to fully dissipate.
Keep the original carton and packing material in a safe
place. You will need it if you have to send the unit for service
or transport it for any other reason.
VALVE FITTING
Fit the valves into their corresponding sockets following the
scheme you can see on the transformers covers and the
indications on the valves themselves which ensure the correct
orientation.
When fitting (or removing) valves, use firm but gentle
pressure. Never use force !
PLACEMENT
The unit should be placed on a safe, stable surface, out of
reach of children or pets. Adequate ventilation is required
above and around the unit. Take care not to expose the unit to
high temperature or humidity.

CONNECTING INPUTS AND OUTPUTS
Situated on the rear panel of the Performance are the input
and output sockets.
IMPORTANT !
Ensure that all other items of equipment to be connected to
the amplifier are switched off before making the
connections.
Do not insert the amplifier AC mains cord until all input
and loudspeaker connections are securely made.
To avoid the possibility of hum and noise, it is good practice
to ensure that all connections to and from the amplifier are
clean and tight, and that all cable runs are neat and tidy.
For best results, AC mains cables should not be placed
alongside signal or loudspeaker cables.
Using RCA phono interconnects of suitable quality, connect
the various sources (CD, tuner, phono) to the corresponding
inputs of the amplifier.
On the rear panel of the unit is also located a power supply
plug for the unit Simply Phono by Unison Research.
The power supply circuit has fuses not accessible externally,
whose characteristics are listed at the end of this manual.
Remember when connecting the loudspeaker cables to the
amplifier output terminals to respect the correct phase (red =
+/black = -) for each channel. With the double loudspeaker
outputs provided on the Performance it is possible to connect
to loudspeakers using bi-wiring, (provided of course that the
loudspeakers are fitted with two sets of input terminals). Note
that the upper and lower loudspeaker sets of output terminals of
6
the Performance are in parallel, therefore either set may be
used for normal loudspeaker connection.
The circuitry of the Performance is conceived to provide an
effective protection from short circuits which may occur at
the outputs.
CONNECTION TO MAINS
Before connecting the mains cable and switching on, make
sure that your local power supply voltage corresponds to the
value shown on the rear panel of the unit.
IMPORTANT !
Never connect the amplifier to a mains supply of a different
voltage to that shown on the unit !
Mains fuses are located in the IEC mains input socket
located on the rear of the unit. The correct value is indicated on
the rear panel and also in the technical specifications at the end
of this manual.
If you need to replace a mains fuse, always use one of the
same type and rating !
OPERATION
After switching on, the Performance stands by for a time of
about 5 seconds, during which the four diodes on the front
panel are on and the outputs are disabled.
This time is necessary to allow the valves to stabilise and
reach the operating temperature. The optimal temperature,
7
corresponding to the best sound performance, is reached after
about 15 minutes from switching on.
After the initial warm up the outputs are enbled, the last
input used is selected and the corresponding led on the front
panel lights on.
VOLUME CONTROL
Before swithcing on the unit, ensure that the volume control
is at the minimum (fully anticlockwise) position.
During the initial warm up keep the volume at the minimum
to avoid any possible sollicitation due to transient effects.
After the warm up time it is possible to regulate the volume
either rotating the volume control handle on the front panel or
pushing the dedicated buttons on the remote handset.
IMPORTANT !
All the operations at the inputs or outputs should be
preferably executed when the device is switched off or
anyway keeping the volume at the minimum.
INPUT SELECTION
The desired input can be selected either rotating the input
selector handle on the front panel or from the remote control.
Inputs are activated in sequence; the one currently active is
identified be the corresponding led on the front panel switched
on.
In case you use the remote control, press the “Sel” button
until you reach the desired input (see remote control functions).
8
REMOTE CONTROL FUNCTIONS
Both volume and input selection of the amplifier can be
controlled by means of the InfraRed remote handset.
The remote control unit supplied with the Performance is fully
compatible with the standard handset of the Unico series
amplifiers and the Unico CD.
IMPORTANT !
When using the wood remote control for the first time press
the learning button (marked by the Unison Research logo).
Every time you will use the standard handset, to switch
back to the wood remote control you will have to repeat
this operation.
This operation has always to be repeated after using the
standard handset to control the Performance.
The remote handset is supplied with two AAA type batteries
(1.5V) which should be inserted into the handset by opening
the rear flap. Ensure that the correct polarity is respected when
fitting the batteries. Replacement batteries should be of the
same type.
SWITCHING OFF THE UNIT
After switching off the unit, wait around 5 minutes before
switching it on again. This time is necessary to allow the valves
to cool down to room temperature.

SAFETY AND MAINTENANCE
Do not open the amplifier !
High voltages are present inside. There are no user
serviceable parts inside, and all service operations should be
undertaken only by an Authorised Service Centre.
Please note that any service work or modification to the unit
carried out by unauthorised personnel may invalidate the
warranty. Refer any service queries in the first instance to your
Dealer.
Do not spill liquid into the amplifier.
If that should happen, switch off immediately and remove
the mains plug from the wall. Have the amplifier checked by an
Authorised Service Centre.
When inserting the mains plug into the wall socket or
mains outlet, make sure that the on/off switch on the unit is
in the off position.
If you do not intend to use the unit for a long period,
remove the mains plug from the mains supply.
Cleaning the amplifier
Cleaning the unit should take place only when it is switched
off and the valves are cold.
Use a soft dry cloth. Do not use solvents or alcohol based
detergents.
Do not rub hard when cleaning the printed lettering.
Never operate the unit if it is covered !
Never attempt to remove the valves when the unit is
switched on !
10
If you need to remove and replace the valves, do so only
when the valves are cold and the unit is switched off.
Replace valves only with others of the same type,
preferably in matched pairs.
Avoid shocks and vibration to the unit, which can damage
or reduce the life of the valves.
