A new era in
tuning accuracy and convenience with Quartz Synthesized All-Pushbutton Memory
preset Tuning, Dual Super Servo System , and Linear Switching.
The Onkyo
TX-4000 Quartz Synthesized Tuner/Amplifier is one of the most perfect stereo
receivers we've ever designed. Nothing else in its price range provides the
brilliant purity, dynamic headroom, and full excitement of its sound.
The Onkyo
TX-4000 brings tuning accuracy to a new level of precision, with an advanced
approach to quartz-synthesized digital tuning. And the amplifier section
provides all the dynamic headroom demanded by today's audiophile recording
techniques. Onkyo's exclusive Dual-Super-Servo System makes it possible, by
allowing the power supply to perform as if it were 50-times larger. And there's
more, LED power metering, memory to pre-set 6 AM and 6 FM stations, and elegant
styling with a flip-down control panel.
