A Note On ngh-Powered Receivers

The extremely 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 the high
power capacity and what it can do.

Concept's amplifier is direct»
coupled, with no capacitors or filters
between the output transistors and
the speakers. Any audio input is
passed directly to the speakers, no
matter how low the frequency, Thus,
any sonic deficiencies in your other
components will become very
apparent, For this reason, you should
use only the highest quality
associated equipment. Inferior
turntables can cause special
problems; theyre likely to have
excessive rumble, and the low rumble
frequencies have the potential to
damage many speakers.

You should also be careful when
handling 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 woofer. It's good
practice to turn the volume down
whenever youre changing a record.

Check the power-handling capacity
of your speakers; if it's low, you
might want to fuse your speakers,
Your Concept dealer can advise you
on that. Prolonged operation at very
high volume levels can also cause
excessive heat to build up in the
voice coils of the speakers, shorten-
ing their lifespan, This is especially
true of the relatively low-efficiency
acoustic suspension bookshelf-type
speakers. Sonically, they benefit most
from the high power, but prolonged
overdriving can lead to premature
speaker failure.

Introduction

Thank you for choosing a Concept
receiver. We think youll 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. It'll save you a lot of
time, and will help you get the full
potential from the Concept.

The Concept 6.5 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 of 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 6.5 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 6.5 volume and tone
controls have multiple detents to
allow precise adjustments that are
easily repeatable. A unique four-range
tone control system offers a new
level of control over the frequency
response, so you can get the best
possible sound in any environment.

A sophisticated tuner section will
match the performance of the finest
separate tuners. Effective application
is made of a 4-gang tuning assembly,
full 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 65 is
a standard of accuracy unmarred by
significant audible or measurable
distortion. This has been achieved by
selecting only premium-quality 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 consis-
tent with making the Concept 6.5
receiver the ultimate synthesis of the
technical, the visual, and the tactile,

Unpacking

Save the shipping carton and all
packing materials. Theyll assure the
receivers safety should you ever
move or ship the unit.

Record the serial number of
Concept 6.5 in the space provided
here. The number may be found on
the rear panel of your receiver.

Placement

You should, of course, place your
receiver where its most convenient.
However, keep it away from direct
sunlight or any other heat source, and
dont block the vents on the under-
side of the unit. CAUTION: To
prevent fire and avoid shock hazard,
do not expose the receiver to rain or
moisture. Also, as the 6.5 is very
heavy, you should be sure it's on a
secure shelf.
