A Note on High-Powered Receivers

The high power output capability
of your Concept receiver will enable
you to hear undistorted musical peaks
and bring fresh clarity and detail to
your music. There are. however, a few
things you should keep in mind
regarding high power capacity and
what it can do.

Concepts amplifier is a wide-band
circuit with no capacitors or filters
between the output transistors and the
speakers. Sound is passed directly to
the speakers even at extremely low
frequencies. Thus, any sonic
deficiencies in your other components
will become very apparent. For this
reason, you should use only the
highest quality equipment with your
new Concept.

You should be especially careful
when using your record player.
Dropping the tonearm on the record, or
flicking dust from the stylus, with the
volume up. can send a power surge
that may damage your speakers. Its
also a good practice to turn the volume
down whenever you're changing a
record.

Check the power-handling
capacity of your speakers; if its low.
you might want to use fuses in the
speaker lines. Your Concept dealer
can give you advice.

Introduction

Thank you for choosing Concept
We think you'll appreciate this product
most it you understand its design
philosophy. Take a few minutes and
read this manual before you set up
your new receiver. It will save you time
and will help you get top performance.

The Concept 12.0D continues the
Concept tradition: stereo receivers
without compromise. Every detail, from
the action of the controls to the size of
the internal heat sinks. has been
carefully crafted by a distinguished
international team of designers and
production engineers. Concept
receivers combine performance of
laboratory standards with bold visual
definition.

A number of design innovations
make the Concept 12.00 a truly
remarkable instrument. All-electronic
tuning with a quartz crystal reference
makes precise tuning as simple as the
touch of a button. Electronic memories
store up to six of your favorite stations
for instant access.

The Concept 12.0D power
amplifier section employs high-gain
voltage amplification followed by
rugged output transistors in a carefully
stabilized, high-speed configuration. A
large toroidal power transformer
efficiently supplies power for the most
demanding musical passages. The
result is a unit that can amplify rapidly
changing audio signals while producing
the lowest possible distortion.

The hallmark of the Concept
12.0D is a standard of accuracy
unmarred by audible distortion. This
has been achieved by selecting only
premium-quality parts and operating
them far below their capabilities. The
result is consistent performance for
years of trouble-free service.
