@ KEH-32000R, KEH-22000R
@ Built-in highly sensitive "Super Tuner" for automatic control of
stereo separation, muting and frequency characteristics to match
the strength of the FM signal.
@ The Best Stations Memory automatically memorizes the six best
(strongest) stations in the six preset buttons in the order of their
strength.
@ Preset scan tuning for sequential recall of preset frequencies.
@ Auto reverse function eliminates the need to turn the cassette
over and allows uninterrupted playback.
@ Built-in Dolby B NR for reduced tape hiss.
(This feature is provided for the KEH-32000R.)
@ Music search function allows automatic playback from the begin-

@ Choice of either 4-speaker or 2-speaker system is possible. When
the 4-speaker system (15 W X 4) is used, volume of front and rear
speakers can be adjusted independently, for optimum sound bal-
ance. The 2-speaker system (25 W X 2) provides more than
enough power for clear, high-fidelity playback.
