ToP-ART™ Total Purity
Audio Reproduction Technology
The fundamental
reason behind the high performance of Yamaha audio components is a
comprehensive design philosophy that we call ToP-ART. It dictates that every
factor that could affect performance is analyzed and optimized. From circuit
design to individual internal parts to feet and knobs, nothing is left to
chance. With the result that each component attains its full potential, so you
enjoy the music the way the artist meant it to be heard.
The Direct Path to
Optimum Signal Purity
The photo below of
the CX-1's interior shows a conspicuous application of the ToP-ART concept. The
path the audio signal traveles is straight and direct, so from beginning to
end, it encounters the last possible amount of interference. The entire interior layout is symmetrical and
logical, resulting in extremely high 85 dB channel separation and ultra-low
distortion of 0,002%. And for the ultimate in signal purity, you can engage the
Pure Direct Switch, causing the signal to bypass teh tone control circuitry.
High Quality Parts
and Materials
In the upper reaches
of audio component performance, small details and even materials take on
increasing importance. Because gold is an excellent conductor and not
susceptible to corrosion, these components have gold plated input terminals and
headphone jacks. The CX-1 goes a step further, with 2-pin gold-plated solid
brass CD and Pre Out terminals for large-size cables. It also uses extremely
thick gold-plated wiring for signal routing. The front and side panels as well
as knobs, are made of extruded aluminum rather than cheaper materials likely to
resonate. Even the nuts and bolts are special types, used only in our separate
components. Our commitment to quality was total, and the results are worth
hearing.
Versatile Control
Centers
The Cx-1 allows you
to select seven different inputs; Cd, tuner, phono, aux, tape 1, 2, 3. It also
has a Rec Out Selector for direct selection of the source to be recorded and
three-way tape copying. This means you can listen to one source while recording
another.
The CX-2 has inputs
for two tape decks and for two VCRs, as well.It also provides a Rec Out
Selector.
Both components come
with a special Power Link cable for connecting them to the MX-1 or MX-2, so the
power amp will turn on and off with the preamp.
