The big features with a digital synthesized tuner are

pronounced tuning ease and accurate tuning. Three

different tuning methods are pessible with the TX-DlOOO.

1. Auto Scan Tuning: By depressed the UP and DOWN
tuning switches, the tuning automatically stops when a
broadcast is received.

2. Manual Tuning: When the tuning mode switch is set
to MANUAL, manual tuning is possible at every
SOkHz for FM reception and at every lkHz for AM
reception.

3. Preset Tuning: Up to six stations each for FM and
AM can be stored in the memory and then called by
fingertip control using the push buttons.

With synthesized tuners, there is a tendency to concentrate
only on improved operating ease, besides accurate tuning
of course, and to ignore the performance and sound quality
which traditional tuners are expected to display. At least,
this is the case when viewed from the standpoint of the
output signal quality. However, with the TX-DlOOO, our
many years of dedication to techniques aimed at repro-
ducing the original sound faithfully merge with our quartz
synthesized techniques to bring you a superior audio
program source in which we have the utmost confidence.

FEATURES

RF Section Featuring Control with LSI Synthe-
sizer

The front end and local oscillator employ a quartz oscilla-
tor 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 intervals for AM, and the signal
is locked so that the tuner maintains its peak performance.
In addition, the RF amplifier which employs a dualgate
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 SOkHz intervals for FM reception and
at 9kHz 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 high-
performance quartz synthesizer system and also to obtain
the best in audio specifications, a linear phase ceramic
filter is employed which allows the group delay character»
istics, 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 improve»
ments 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
iskHztgg dB.

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).
