Notes

A hi-fi FM stereo quartz lock digital synthesizer tuner with a digital frequency FL display housed in a metal case with optional wooden side panels. Features Direct Comparator Technology and an Audio Current Transfer (ACT) circuit. With a 10 step Signal Strength indicator, Automatic tuning, Manual tuning, Memory preset tuning (8 AM or FM radio stations), a Program Function, the SCAN/READ button which scans through all the preset radio stations playing each one for 10 seconds, push button switches for Wide and Narrow IF Bandwidth, Hi-Blend, Muting, Mode, Antenna selection (A or B), and a Calibration Tone button which produces a 400Hz, 50% mod. signal for calibrating the recording level on a tape deck. Two FM antennae terminals (A and B) and an ACT output connector (a special ACT cable is supplied for connecting the tuner to an amplifier).
