Description
Product descriptionFM/AM tuner of the same size as L-80V and L-80.The front end of the FM tuner section employs a high-frequency amplification circuit using a quadruple variable capacitor and FET, and is composed of an interstage demodulation circuit, a mixer circuit, and an oscillator circuit with low harmonic distortion, achieving excellent values ??in various characteristics. By realizing this, stable FM reception is achieved from weak electric fields to strong electric fields.The intermediate frequency amplification circuit employs two sets of linear phase type ceramic filter elements, an LC demodulation circuit, and a wideband discrete transformer to obtain excellent characteristics over a wideband.The MPX circuit uses carefully selected PLL type ICs. A constant voltage power supply circuit is adopted in the power supply section, increasing stability against fluctuations in AC power supply voltage.Equipped with additional functions such as FM high blend circuit, FM muting circuit, multipath detection terminal, and output level adjustment.The FM muting circuit uses a pure electronic system using FET, and the set muting width does not change regardless of the strength of the high frequency input level. Also, there is almost no pop noise caused by muting ON/OFF.The AM tuner part uses a double variable capacitor type without a high frequency amplification circuit, but excellent effective selectivity is obtained by adopting a ceramic filter in the intermediate frequency amplification circuit.?Main specificationsModel FM/AM tunerIHF practical sensitivity 2?V (83MHz, 100%mod)2 signal selectivity 60dB (83MHz, 100?V, ±400kHz)Amplitude modulation suppression degree 50dB (83MHz, 1mV)Capture ratio 1.8dB (83MHz, 1mV)Image ratio 90dB(83MHz)IF interference rejection ratio 90dB(83MHz)Total harmonic distortion mono: 0.2% (1kHz)stereo?0.3%(100Hz)?0.3%(1kHz)?0.4%(6kHz)SN ratio mono:72dB(83MHz, 1mV)stereo:68dB(83MHz, 1mV)70dB (listed in the general catalog)Frequency characteristics 50Hz~12kHz -0.5dB(mono&stereo)20Hz?15kHz -2dB(mono&stereo)Stereo separation 43dB(1kHz)30dB(50Hz?10kHz) Antenna impedance 300?
