    The tuner design is based on microprocessor-controlled digital frequency synthesised tuning and provides 19 FM and 9 MW preset with C-MOS memory back-up.
    The unit provides variable speed up/down scanning, automatic search, as well as manual tuning. Automatic FM mute is provided to eliminate irritating interstation noise. The quartz-locked tuning system is adopted for ultimate tuning accuracy and minimal frequency drift. An informative Fluorescent Tube Display electronically generates digital frequency readout, "Tuning " indication, "Stereo" reception, and, when selected, preset channel number. For the finest reception quality under adverse signal conditions, the Cyrus Tuner has FET front-ends (dual-gate with automatic gain control on FM). The FM mixer oscillator is buffered to ensure high immunity to interference, and Ceramic filters are incorporated for high selectivity on both AM and FM wavebands. The Cyrus Tuner offers "Sliding Stereo" decoder maintaining full channel separation on strong signals, and changing gradually to mono for fullest noise suppression on weak signals. PLL decoder circuitry produces a stable audio signal with optimum channel separation, and an SISC filter cuts out interference on stereo broadcasts.
