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 image ratio while safeguarding against cross-modulation. Additionally, the lF stage is equipped with lC 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 de- coder (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 cir- cuitry 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 equipped with a large, illuminat-
ed 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. lt benefits greatly from the ferrite-
loopstick antenna, as well as the combination of double tuning
IFT and silicon transistors employed throughout for perfect
reception.
FM MUTTIPATH TERMINAT FOR IDEAL RECEPTION The greatest enemy of clear FM stereo sound is FM multipath interfeiance, 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 con- nect the Pioneer Stereo Display (Model SD-1000) to the FN1
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" bet- ween stations. Among the usef ul auxiliary circuits provided with
the TX-600are an extra pair of tape output jacksthat permit di- rect tuner-to-tape recording.
