introduction

Thank you for choosing a Concept
receiver. We think you'll most
appreciate this product if you under-
stand it In the context of its design
philosophy. Take a few minutes and
read this manual before you set up
the receiver. Itll save you a lot of
time. and will help you get the lull
potential from the Concept.

The Concept 4.5 is the result of a
concentrated effort to design a line of
stereo receivers without compromise.
Every detail, from the- action of the
controls to the surface area of the
internal heat sinks. has been carefully
thought out and crafted by a
distinguished international team of
designers and production Engineers.
A laboratory standard oi performance
is augmented by bold visual
definition. The final product is a finely
crafted instrument that will satisfy the
most discerning audiophile

A myriad of design innovations
make the Concept 45 as easy to use
as to listen to. Most of the binary
functions are controlled by newly
engineered pushbuttons for maximum
operational simplicity. The buttons
themselves use light-emitting diodes
to provide positive visual indication of
the function.

The Concept 45 volume and tone
controls have multiple detents to
allow precise adjustments that are
easily repeatable. The tone control
and loudness contour circuits are
designed for you to enjoy sound
quality in most environments-even
at low volume.

A sophisticated tuner section will
match the performance of the finest
separate tuners. Effective application
is made of a4-gang tuning assembly.
lull Quadrature detector. hand-picked
filter elements and the latest Phase-
Lock Loop circuitry. Tuning itself is
unusually smooth. due in part to the
massive internal flywheel and bearing
assembly. Exact tuning is aided by a
calibrated meter and a stereo
indicator light.

The hallmark of the Concept 4.5 is
a standard of accuracy unmarred by
significant audible or measurable
dlstortion. This has been achieved by
selecting only premiumouaiity parts
and operating them far below their
related capabilities. A deliberate
benefit of this design criterion is a
dramatic decrease of breakdown due
to parts failure.

Surely this is the most ambitious
way to create a product, but
consistent with making the Concept
45 receiver the ultimate synthesis of
the technical, the visual. and the
tactile.
