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).
