For sale: JVX FX-1010TN Computer-Controlled Digital Synthesizer Tuner in flawless condition and comes complete as originally packaged. I bought this as new old stock a few years ago and have enjoyed it but no longer need it. This is a high-end tuner the likes of which, are not being made anymore- unless you want to spend multiple thousands. This is a great opportunity! The primary function of a tuner is bring in the station you want precisely and accurately, whether its near or far. Using the latest circuit designs and device, weve made our tuner from the Super Digifine series, the FX-1010TN, more sensitive, selective and interference resistant than ever - the reason the tuner is able to provide wide dynamic range, low noise and low distortion, and wide frequency response. Its also extremely easy to use, thanks to the amazing power of an advanced microprocessor. Reception servo for optimum reception from any station, almost anywhere. A built-in microprocessor detects the strength of a tuned station and compares it against the degree of interference from adjacent stations. Then, depending on the degree of interference, the microprocessor selects the optimum operation mode for front-end. IF and multiplex decoder stages (adjusting such parametersas RF gain, IF bandwidth, Quieting Slope Control and mono/stereo). Therefore when interference is excessive, a narrow IF bandwidth is automatically chosen to prevent noise. And if theres no interference, then a wide IF bandwidth is automatically selected to give you remarkably clear sound. When a signal level is overly strong, the RF gain is reduced to avoid saturation distortion; when its weak, sensitivity is increased. Moreover, the tuner is equipped with inpuls to connect two antennas; each may be oriented for the best reception of stations in diametrical opposition to the other . Conveninlly, the position of antennas, A or B, may be stored in memory station by station, which allows most precise reception from any station, without multipath distortion. To add to convenience, the selected parameters are clearly indicated on a large fluorescent display, letting you quickly confirm tuning status. Features for low noise and low distortion JVC uses components and devices to ensure lowest possible noise and distortion and widest dynamic range from your favorite stations. Opticalink System This system is one developed by JVC to ensure highest purity from your favorite station. It uses eleven photocouplers (each consisting of a photoemitter and photosensor) to electrically decouple the analog from the digital section. As a result, interference between the two due to electric coupling is completely eliminated. This puts an end to digital noise and removes any trace of muddiness from the sound you hear. In the FX-1010TN, each of the analog/tuner, digital control and Opticalink sections is mounted on its own PC board to shut outmutual interference and noise. And the digital control section, which can be a source of noise generation, is fully shielded to contain noise.MOS FET front-end The front end employs a dual-gate MOS FET which, along with high-Q varicaps, makes it as sensitive, selective and resistand to interference as a front end using an elaborate 5-ganged tuning capacitor. Therefore, the Signal-to-Noise ratio and interference rejection capability are outstanding. Low-distortion IF section The IF section of the FX-1010TN features ceramic filters coupled with a distortion reduction circuit for better phase response and low distortion PLL detector and Beatless PLL multiplex circuit. A PLL detector combines low distortion and high Signal-to-Noise ratio for dynamic and wide-range sound. Also the FX-1010TN uses a new PLL multiplex circuit that electrically filteres out beat noise-noise resulting from two or more frequencies interfering with one another. In a conventional CR-type MPX circuit using a VCO (Voltage Controlled Oscillator), however, a device called an anti-birdie filter is used to remove beat noise, but the coils in the circuit tend to degrade signal qulaity. In our beatless multiplex circuit, moreover, a pilot canceller is featured to suppress the leakage of the pilot signal, thus obviating the need for a 19 kHz filter, another component that would harm sound quality. Active Filter To prevent leakage of the 38 kHz subcarrier contained in a stereo broadcast, an LC filter built from coils and capacitors is commonly used, but, due to the magnetic distortion the core of the coil causes, this system tends to degrade sound quality in the FX-1010TN, however, an active filter; with coil eliminated, it provides better high-frequency response, wider separation and higher Signal-to-Noise ratio.
