Technics Brochure Highlights

Linearly variable tuning capacitor, FET front end and 5-stage differential IF amplifier for high sensitivity and selectivity, and low capture ratio. Three "Flat Group Delay" ceramic filters for minimal phase distortion. Chebyshev-type low-pass filter permits wide, flat frequency response with sharp attenuation of 19 kHz pilot signal. Phase locked loop IC in FM MPX circuit for wideband, stable stereo FM separation. Test signal generator for accurate setting of levels on tape deck. Antenna terminals directly connected to front end circuit board, for excellent spurious response and image rejection. Zero-center and linear signal strength meters. FM muting to suppress interstation noise. FM linear dial scale. Simulated wood cabinet.
