FM Stereo Tuner CR-1000

• alternative name: Heath Company

CR-1000. Combined with the GRA-1000-1 Power Amplifier, the Tuner offers performance specifications rivaling those of many costly home stereo hi-fi systems ... an honest 7 watts of car-filling power (3.5W min. per channel into 4 ohms) with less than 2% THO; frequency response ±1 dB, 3 Hz to 15,000 Hz; 3 uV sensitivity; 60 dB selectivity; 40 dB min. separation. Ten transistors, 4 ICs and 4 diodes make up the reliable solid-state tuner circuitry. Advance-design features include a muting circuit for noise quieting between stations; automatic frequency control (AFC) for locking-in FM stations. Front-panel convenience features include large Tuning, Volume, Tone and Balance control knobs; on-off rocker switch; high-visibility stereo indicator light and center-tune indicator Iight. .. all designed to give you fingertip control of FM stereo programming without taking your eyes off the road. All hardware supplied for under-dash or transmission hump mounting.
