INTRODUCTIONINTRODUCTION

Audio Refinement was conceived to offer the renowned musicality or "sonic signature" of YBA
Electronics by Yves-Bernard ANDRE' in a more affordable range of products. It benefits from the
same design philosophy and attention to minute detail that is the hallmark of YBA.

Thank you for your purchase of the Audio Refinement Pre-2dsp, pre/processor. It is precisely crafted
innovatively designed and extremely reliable. We appreciate your faith in our products and we trust
that your Pre-2dsp will reward you with many years of audio/video pleasure.

Please read the operating instructions before connecting the Pre-2dsp to your audio/video system.

DESIGN PHILOSOPHYDESIGN PHILOSOPHY

An important design goal for Audio Refinement is the control of parasitic vibrations. These me­chanical vibrations in the air have a negative effect on the purity of sound. The impact of these
vibrations depends on the size of the audio equipment, the internal components and the rigidity
of the construction. The solutions chosen for Audio Refinement include:

The mechanism is designed to be as compact and as rigid as possible. The small physical size of
your Audio Refinement Pre-2dsp moves the resonant frequencies out of the audio domain.

The PRE/PROCESSOR has only 3 feet which is the ideal way to drain vibrations.

The transformer is suspended to reduce the transmission of its vibrations to the rest of the circuitry.

The choice of materials is also an important part of the design of your Audio Refinement Pre-2dsp,
the bottom is made of non-magnetic aluminum, the other parts are brushed and colored
aluminum.

UNPACKING AND INSPECTIONUNPACKING AND INSPECTION

Carefully unpacking your Pre-2DSP and locate the enclosed accessories:

RC-DSP Remote Controller with AA batteries
Detachable AC Cord
Remote Connection cord
Owner's Information

CARE & USECARE & USE

Ensure that your main AC voltage matches the voltage marked on the rear of the unit and on the
exterior of the shipping carton.

To avoid damage to your Pre-2dsp, we recommend that you disconnect the AC during electri­cal storm or if the unit will be unused for an extended period of time.

Do not handle your AC cord with wet hands. If liquid spills on your Pre-2dsp, unplug immediately
and contact your dealer for cleaning instructions.

Do not remove the top cover of your Pre-2dsp or attempt to modify any circuitry. This will void your
guarantee and could result in serious injury.

Always turn the Pre-2dsp off before making any connections. Ensure that the speaker cables of
your power amplifier do not touch each other. A short circuit will damage the unit and is not

covered under the guarantee!

Keep your Pre-2dsp out direct sunlight. Because it could interfere with the remote control sensor.

Keep the Pre-2dsp away from heat sourcres such as hot air ducts, radiators and moistures sources
such as open windows.
