Tuner Pioneer F 757 : 2 antene, Made in Japan, afisaj centru, 36 memorii, MPX filter, poze reale, culoare neagra.
The synthesizer tuner which carried newly developed
technologies, such as DDDtypeIV and MPX NR, and pursued the low
distortion and high S/N.
Digital conversion of the radio wave is carried out, it gets
over to an audio signal direct, and DDDtypeIV to which DDD which
realized the low distortion and high S/N was evolved further is
carried.
In order to reduce distortion generated with IF filter, by
the original newly developed linearlizer of Pioneer, the
demodulation signal was returned to the input unit, and is
canceled, and the higher S/N and separation are
realized.
High precision 4-unit front end is carried in front
end.
The tuning element constituted the receiving part of the high
precision as a twin varactor diode, RF amplification part of dual
MOS-FET excellent in the linearity, and a balanced mixer circuit,
and has improved an inter-modulation property of 10dB or
more.
Moreover, RF attenuator circuitry is carried in the front end
input, stonewalling exclusion capacity is heightened further, and
the influence of an adjoining office is suppressed.
MPX NR by newly developed original IC is carried, and the S/N
ratio is improved also at the time of a weak-electric-current
community reception.
The measure against vibration proof is put into practice by a
honeycomb chassis, filling of the resin to a large-sized insulator
and local OSC module, etc.
Moreover, technologies, such as a low pass filter by FDNR
which has improved S/N and distortion, Normal / super narrow change
which operates in an independent distorted regulation circuit, are
adopted.
Furthermore, the power-source part using an audio peculiar
part or an oxygen-free-high-conductivity-copper line is
adopted.
AM and FM monophonic recording also carry the functionalities
in which a natural feeling of a stereo is obtained, such as a
spectrum simulated stereo, a 36-game random pre-set, a two-line
antenna input.

- Digital-Direktdekoder Typ IV: Überragende Kenndaten durch digitale Signalverarbeitung mit direkter Wandlung der frequenzmodulierten HF-Signale in die Komponenten der Stereo-Kanäle. Zusätzlich sorgt ein Linerarisierungswiderstand dafür, daß bei den ZF-Bandbreiten NORMAL oder SUPER NARROW Störgeräusche und Verzerrungen drastisch verringert werden.
- MPX-Rauschunterdrückung: Erbringt einen besseren Fremdspannungsabstand ohne Abstriche an der Trennschärfe
- Spektrumsimuliertes Stereo: Liefert eine überzeugende Stereosimulationa aus UKW- und MW-Monosignalen
- FDNR-Tiefpaßfilter: Das aufgewertete Tiefpaßfilter an der Ausgangsstufe sorgt für eine erhebliche Verringerung unerwünschter Trägerfrequenzreste und damit für eine Minderung von Störgeräuschen und Verzerrungen
- Eingangsstufe mit ID MOS FET: Hohe Empfindlichkeit und ähnliche hohe Trennschärfe wie bei einem Vierfach-Drehkondensator
- HF-Abschwächer: Verhindert ein Übersteuern bei extrem stark einfallende Ortssendern
- Festsenderplätze für 36 UKW/MW-Stationen: Einfache Speichereingabe und Abruf auf Tastendruck
- Umschaltbare ZF-Bandbreite (UKW): NORMAL für hohe Empfangsqualität bei sauberem Empfang, SUPER NARROW für erhöhte Trennschärfe
- Doppelter ANtenneneingang: Zur Erweiterung des Empfangsbereichs und Vermeidung von Mehrwegempfang.
- Schwingungsdämpfende Konstruktion: Harzgefülltes Oszillatormodul, wabenverstärktes Chassis und große Dämpferfüße zum SChutz vor Verfärbungen durch Trittschall und Resonanzen
- MPX-Betriebsartschlater: AUTO/MONO
- Hochwertige Bauteile für einen besseren Klang: HF-Stufe mit nach HiFi-Kriterien ausgewählten Halbleitern und Kondensatoren, Verdrahtung aus sauerstofffreiem Kupfer (OFC)
- Eingangsempfindlichkeit (mono): 11,2 dBf (1,0 µV, 75 Ohm)
