PIONEER presents the greatest DC power story ever told. It's a simple fact of life that the more pure pure power a receiver possesses, the easier it can reproduce music without straining. And at 270 watts per channel, even the most demanding piece of music will hardly cause the SX1980 to flex its considerable muscle. Each channel, for example, ha a separate DC power configuration that helps to provide richer and more accurate bass. Pioneer has developped a 22 pound toroidal core transformer that's far less susceptible to minor voltage variations. So you get cleaner, clearer sound. Instead of pushing power transistors to their limits Pioneer invented new transistors that last longer and eliminate the need for fans that can cause electrical interference. All these inovations give the SX1980 a total harmonic distorsion level of less than 0.03% from 20 to 20,000 hertz. Inside the SX1980 there's a quartz crystal generating the perfect frequencies of every FM station, so as you rotate the tuning dial, a special integrated circuit compares the station you're trying to tune to it's perfect frequency. When the station is tuned exactly right (all this takes about half a second), a "fine tuned" light comes on; the receiver then senses when you let go of the tuning dial and automatically "locks" onto that broadcast. Technical data: 270 W/ch (min. RMS, 8 ohm 20-20,000 Hz, no more than 0.03% THD) Dimensions: 560 W x 211 H x 497 D mm Weight 35.4 kg.
