Realistic STA-2200


The Realistic STA-2200 is a high-powered AM/FM Stereo Receiver utilizing the latest in digital computer technology for a product unmatched in quality, versatility and reliability.

The built-in microprocessor-controlled CMOS LSI Frequency Synthesizer eliminates the dial scale and replaces it with an ultra-accurate digital readout.

The STA-2200 tunes up or down the dial automatically, stopping at each station that's on the air in your area.

In addition, the receiver features:

  • FM front-end uses a dual-gate MOS FET for immunity from problems caused by overloading (local strong signals) and other spurious-response effects. Tuning is with Varicap Diodes, controlled by the Microprocessor (no mechanical tuning problems).

  • FM IF section incorporates 3 ICs resulting in very high gain and outstanding limiting characteristics (ultra-low-noise FM reception). Three linear-phase ceramic filters assure superb selectivity with lowest distortion. Quadrature detector and PLL stereo detector gives you the best possible FM and FM Stereo Signal with state-of-the-art separation.

  • PLL Frequency-Synthesizing CMOS IC provides no drift, digital tuning.

  • 12 Memory Locations store your favourite stations for easy one-button access (six for AM, six for FM).

  • Real-time clock.

  • MOS-FETs in the power amplifier for high-power with ultra-low distortion even at high frequencies.

  • Automatic Protection Circuitry to protect against voltage surges, overloads, shorts and overheating.

  • Switchable DOLBY FM processor to let you enjoy the low-noise and increased dynamic range of stations broadcasting Dolby encoded music.

The pre-amplifier section allows you to tailor the sound to your preference with selectable turnover on the Tone controls and a wide range of inputs.

The Power Amplifier delivers a solid 60 watts RMS per channel. Enough to drive two pairs of even the most inefficient speaker systems.
