Solid State Stereophonic AM/FM Receiver (1970)
The new Fisher 500-TX is a highly advanced receiver that houses all the electronics of a complete high fidelity stereo system in one compact, decorator styled unit. It is actually a no-compromise combination of three separate Fisher components: a sensitive, wideband AM FM stereo tuner; a versatile, low-noise preamp control unit; and a wideband, low-distortion power amplifier.
The FM-tuner section itself incorporates several design innovations, among them a dual gate FET front end with Tune O Matic and Autoscan station selection and an extremely selective crystal IF filter, an integrated circuit IF amplifier, and a multiplex decoder with exclusive Stereo Beacon.
While relatively simple to operate, the 500-TX is also extremely versatile, permitting immediate radio listening enjoyment with just the addition of your speakers and the FM dipole antenna, and with the subsequent connection of suitable accessories, expansion into a complete home entertainment system.
It will play a wealth of program sources: AM, FM, and FM stereo broadcasts, mono and stereo phonograph records, plus any one of a wide variety of auxiliary sources of your choice. Special facilities are also included for adding reverberation with the Fisher K-10 Dynamic Spacexpander, for tape recording the selected program while listening, and for playing back the recording or any pre recorded tape through the receiver at your convenience.
Whatever the program, the unit's complete array of controls and switches enable you to shape its sound characteristics to suit your personal tastes and listening conditions, while also providing selective listening through any desired combination of main speakers, optional center and remote speakers, and conveniently connected stereo headphones.
In all cases, the 500-TX's advanced design and superior performance assure you of sensitive, noise free radio reception; excellent channel separation on all stereo sources; wideband audio response; and ample low distortion power reserve; characteristics producing that effortless 'transparent' sound that has become the hallmark of Fisher transistorized components.
