A medium-priced
stereo AM/FM solid state tuner with advanced circuitry, high sensitivity and
outstanding tonal response.
In designing the new
TX-600 tuner, the objective of Pioneer engineers was to create an
uncompromising unit of excellence that could be offered to the music public at
a very reasonable price. The performance specifications of this new Pioneer
component go a long way to show how this objective was fulfilled. The TX-600
combines FET, ICs and ceramic filters to offer unusually high sensitivity and
image ratio, along with improved selecitvity and capture ratio. The sound that
emanates from the unit is finely balanced, solid stereo sound. And although
this Pioneer tuner reflects the very finest of engineering and performance
through and through, it is priced surprisingly low so that even the stereo fan
operating within a limited budget may fit the TX-600 into his group of
components.
Advanced Circuitry
In FM Front-end
Nothing has been
spared to make the TX-600 one of the finest performing tuners in its price
range. Circuitry in the FM tuner section
includes an FET to raise sensitivity and imge ratio while safeguarding against
cross-modulation. Additionally , the if stage is equipped with IC and ceramic
filters which are necessary for improved selectivity and capture ratio. You
will find that the TX-600 receives signals with rare sensitivity even in areas
where these signals are usually weak. Moreover, since the MPX decoder (the
circuit that separates the two channels of FM stereo programs) works on the
highly accurate switching system, it provides a very wide frequency response
and stability. Then there is also a discriminator amplifier included in the set
that assures sharp channel separation at all times. All of these circuitry
features are especially vital today in times of increasing numbers of FM
stations.
Easy Tuning
FM tuning on the
TX-600 is accomplished with ease, thanks to the extra-wide linear type dial
scale. Even in metropolitan areas where a large number of FM stations may
exist, this Pioneer tuner has the knack of separating station signals,
affording you precision tuning with minimum noise and maximum stereo
separation. The TX-600 is also eqipped with a large, illuminated dial and dual
meters - one a signal strength meter, the other a center zero meter. When you
are using AM, the signal strength meter alone is sufficient for precise tuning.
AM Tuner Section
The AM tuner section
of the TX-600 is designed for optimum sound quality and reception. It benefits
greatly from the ferrite-loopstick antenna, as well as the combination of
double tuning and silicon transitors employed throughout for perfect reception.
FM Multipath
Terminal for Ideal Reception
The greatest enemy
of clear FM stereo sound is FM multipath interference, which most often occurs
when the path of the signal is deflected by a mountain or high-rise building.
This interference, however, can often be reduced by changing the direction of the
antenna in the optimum direction. The TX-600 is equipped with an FM multipath
terminal to help you discover the ideal antenna position. To do this requires
that you connect the Pioneer Stereo Display. (Model SD-1000) to the FM
multipath terminal on the rear panel of the TX-600.
Additional Features
The TX-600 has a
number of other important features that add up to maximum sound performance.
There are separate AM and FM output level controls, which can be set to
compensate for differences in AM and FM signal strengths, so that the master
volume control will not require readjustment-when the selector is switched.
Also, there is an FM muting switch, that helps to eliminate FM inter-station
noise, that irritating "rustling" between stations. Among the useful
auxiliary circuits provided with the TX-600 are an extra pair of tape output
jacks that permit direct tuner-to-tape recording.
