Crown FM 1 tuner

FM Stereo Tuner
An FM only stereo tuner with phase-locked loop digital tuning and LED metering readouts. All tuning functions are touch-controlled for no-moving-parts operation. The memory function allows the pre-setting of five favorite stations for instant recall. The scan search feature allows the listener to sweep up and down the dial, stopping either at every active station or only those broadcasting in stereo automatically. The variable muting control allows the user to set the tuner to receive only signals of sufficient strength to assure noise-free reception. All phases of operation are handled smoothly and facilitate the highest order of tuning accuracy and convenience. Ther is LED  metering for multipath and signal strength variable interstation muting control, selectable stereo de-emphasis and a multiplex filter.
