Information

RF Section Featuring Control with LSI Synthesizer The front end and local oscillator employ a quartz oscillator as a source of the reference signal, and this is controlled by the synthesizer PLL circuit. This provides accurate tuning with the broadcasting station frequency, 50kHz intervals for FM and 9kHz or 10kHz intervals for AM, and the signal is locked so that the Tuner maintains its peak performance. In addition, the RF Amplifier which employs a dual-gate MOS FET and the varactor diode, which is selected under strict quality control standards, enhance the noise factor, and by their sensitivity and ability to suppress interference they home in on the desired signals in a complex signal environment. PLL Synthesizer which Adds a New Dimension to Operating Ease Quartz PLL synthesizers have made it possible to receive signals stably and with a high degree of precision. This tuner, however, goes a step further. It offers FM auto scan tuning where the stations are tuned automatically, and manual tuning which enables stations to be picked up at fingertrip control at 50kHz intervals for FM reception and at 9kHz or 10kHz intervals for AM. Furthermore, there is a memory function capable of storing up to 6 stations each for AM and FM. Once the frequencies of the stations have been stored in the memory, they can be called back at the touch of a button. The reception mode is indicated by a digital display, and there is also a memory display and a signal indicator which makes tuning much easier. High-performance IF Section In order to do justice to the features of the highperformance quartz synthesizer system and also to obtain the best in audio specifications, a linear phase ceramic filter is employed which allows the group delay characteristics, which have a bearing on the distortion and resolution, to be flat. PLL MPX with Self-contained Auto Pilot Signal Canceler This Tuner incorporates Pioneer original auto pilot signal canceler which tracks the pilot signal level, and an NFB PLL MPX decoder. Together, they help yield improvements in the overall characteristics such as a signal-to-noise ratio of 72dB, distortion of 0.06% and a separation of 55dB as well as a wide-range frequency response of 20Hz to 15kHz+gjdB. Off-air Recording Function A built-in oscillator generates 330Hz reference signals (50% modulation) which are extremely handy for recording programs off the air (FM).
