Realistic STA-2200

Description

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.

Noise reduction system manufactured under licence from Dolby Laboratories.

Yes it is a quite good receiver. I had one I got in 81 for a discount of 400 instead of 600 list. Played well for many years. I eventually gave it to bro. who does not use it. Issues after many years, the typical deal with noisy pots and flaky switches that all need cleaned. And that cool display is like any other green glow display, it gets weaker and weaker and weaker....good luck fixing that. That is the Achilles heel of it I suppose. IF that goes out you tune FM in the blind. However with the presets available, that can be overcome to some extent. Well made machine.

I have worked in the Q-Lab for Tandy from 1976 to 1983. This receiver took a lot of thought and planning that went into the design of this 2200 during 1978 and 79 during it's pre-release. This is probably the best built and sounding 60 watt per channel receiver ever produced up until it's time and possibly there after, and definitely the best sounding receiver built by anyone in 1980 with it's MOS-FET output design. In my opinion it is the last quality receiver sold by Radio Shack. It wasn't very profitable to the company as so much time and money was put into this nice unit as a finally chance to claim it's reputation in the high end audio field at the time. The cutbacks already had begun on the flagship STA-2100's to produce them cheaper while sacrificing the quality of what it once was. Although the 2200 was cheaper to build than the 2100's it was a much more sophisticated design especially in the AM/FM PLL circuit designs and in-house alignment procedures which took special training during manufacturing production standards. Anyone who heard these units for the first time was in for a real treat. I have two of these now, one with restored electrolytics which I would highly recommend as some of the IC's are extremely hard to come by these days and you definitely don't want DC shooting up path into these with leaky out of spec caps.

The STA-2200 is still the best sounding stereo receiver under 100 watts these ears have ever heard to this day.

It's a classic receiver that still plays up to the test of time in the audiophile world today..

re: STA-2200

Sold in 1980 & 81, the STA-2200 is by far the best sounding receiver ever sold by the Shack. This due to it's use of Hitachi MOSFET output transistors and the unit being designed around sound quality. Unlike other Realistics of the time, this receiver was not boomy, and engaging the loudness circuit didn't result in loud muddy bass. Stock the FM tuner was okay, the AM dreadful. After having two of these units tuned up by a tech with the proper RF test equipment, it turns out the tuners are excellent, including AM. Perhaps being a new (digital) design they didn't know how to peak them in manufacturing. The plastic lip on the sliding door cover seemed to break in the first week of usage; superglue solved that problem. Manufactured by Tandy Electronics in Korea.

I need a manual on the sta 2150
