AM/FM Stereophonic Tuner (1962-63)
The Fisher R-200 AM/FM Multiplex stereo tuner is an instrument so close to the perfectionist's ideal that you'll be especially glad if you haven't made a permanent tuner choice yet.
The Fisher engineering team that created the world's most sophisticated FM Stereo Multiplex designs has outdone itself.
Here is a tuner that combines the latest Fisher ideas on FM Stereo with an AM section of the highest attainable fidelity.
For those who require superb AM reception in addition to the ultimate in FM Mono and FM Stereo, the R-200 is the tuner regardless of price.
The FM front end is of the new Fisher Golden Synchrode design, a remarkable new development that permits the greatest possible overload margin and rejection of unwanted signals, as well as amazingly simple and reliable circuitry.
Five wide-band IF stages, four stages of limiting and an extremely linear wideband ratio detector complete the basic FM section.
The Multiplex section utilizes the time division system - found superior to all others in extensive field tests.
The exclusive Fisher Stereo Beacon instantly turns on an indicator light when a Multiplex broadcast is being received and automatically switches the tuner to FM Stereo operation.
The AM section incorporates a tuned RF amplifier, followed by a converter and two IF amplifiers; other AM features include a three-position bandwidth switch and a 10 Kc whistle filter.
Performance? The FM sensitivity of the R-200 is 1.6 microvolts; the capture ratio is 1.8 db. Even Fisher engineers find these figures difficult to believe but test instruments don't lie. The AM sensitivity is 5 microvolts for 2 volts output.
