Here is the
best example of Rotel's cost-performance outperformer. RA-311 is a new and very
versatile stereo pre-main amplifier that let you handle all kinds of program
sources. Besides record player, note two tape recorders you can operate and
with dubbing, too. And yet another input for an additional component, not
counting one for tuner. All can be simply and smoothly controlled by this
amplifier's amplr 20W + 20W RMS continuous power both channels driven at wide
frequency response and negligible distortion, along with other efficient
controls and switches.
