Realistic STA-90
Brief description[edit]
Your new STA-90 is a highly versatile AM/FM Stereo Receiver which delivers enough power to drive almost any speaker system. The “honest” 45 watts per channel over the entire audio bandwidth will drive both “main’ and ‘remote’’ speakers. And it has the performance and convenience features that distinguish a truly great receiver. Built-in Quatravox® synthesizes 4-channel sound from ordinary stereo sources. Whenever you’re ready, just add a second set of stereo speakers for the rear channels. It's the best of both worlds—stereo and 4-channel. At Radio Shack we also believe a receiver should look as good as it sounds. So we built the STA-90 with a blackout dial and a dial pointer that changes from yellow to red to indicate stereo broadcasts. Like every Realistic component, the STA-90 comes with a beautiful oiled walnut case—and it doesn’t cost you a penny extra.
