Pioneer TX-6200
TX-6200 - Pioneer's easy-to-operate high quality tuner. A compact, sensitive, practically-priced tuner.
Low-noise junction FET in FM front end.
Exclusive FM IC with 5-stage limiter.
MPX circuit with high-performance IC for wide separation.
Large signal meter and wide linear FM dial scale for easy tuning.
MPX noise filter.
A compact, sensitive, practically-priced AM/FM stereo tuner with FET-equipped front end, monolithic IC, and high-performance IC in the MPX circuit
Although its price is certainly one of its most attractive features, the TX-6200 AM/FM stereo tuner from Pioneer is a sensitive, versatile and extremely competent piece of stereo equipment. For one thing, it is equipped with all the latest solid-state circuitry, including an advanced three-gang variable capacitor in its front end as well as a low-noise junction type FET in its RF amplifier stage. Performance is exceptional, with overall characteristics such as superb spurious rejection and image rejection, and excellent FM sensitivity. If you will be operating the TX-6200 in metropolitan areas of excessive FM signals, you'll discover this tuner to be equal to the task of suppressing jamming and noise while offering an astounding degree of station selectivity. Complete with all necessary controls, and an advanced multiplex circuit for wide stereo separation, the TX-6200 is ideal as the first for your investment of stereo components. Its cost/performance versatility alone makes it one of the great stereo values of the year.
FM Front end with junction type FET
The front end of any tuner is the key factor for receiving weak station signals while offering stability against excessively strong signals suppressing distortion and jamming in the TX-6200 Pioneer has employed a frequency-linear three-gang variable capacitor and low-noise junction type FET in its front end. These features add up to outstanding IHF sensitivity of 1,9 µV as well as image rejection of more than 60 dB and spurious rejection of more than 75 dB. These performance characteristics mean that the unit is more than sufficient to receive very weak signals, while providing necessary stability and excellent rejection characteristics.
Exclusive FM IC with 5-stage limiter
A new and exclusive FM IC is employed in the IF section of the TX-6200. this IC forms the five-stage limiter to ensura extremely stable limiter characteristics against any kind of input level fluctuations. At the same time the circuitry improves capture ratio AM suppression and Signal-to-Noise Ratio. Another feature the quadrature detector adopted in this FM IF section ensures linearity over the wide frequency bandwidth while suppressing distortion to an inaudible level.
Phase-linear ceramic filters
Two phase -linear ceramic filters are utilized in the IF section to assure excellent phase characteristics over the wide frequency bandwidth. Each filter has two elements making for a total of four ceramic filter element and leading to an IHF selectivity figure of more than 60 dB. What this means is that the TX-6200 sharply separates the adjacent stations, especially in areas of multiple station signals.
MPX circuit with high performance IC
A high-performance IC is also adopted in the double-balanced differential demodulator in the tuner's MPX circuit leading to wide separation of more than 40 dB at 1 kHz and more than 30 dB over the 50 to 10 kHz range. An additional sharp low-pass filter is employed for suppressing carrier leakage.
