Your Marantz Model 2230 all solid state receiver incorporates the advanced circuitry for which Marantz is famous in the audio component industry. Unparalled technology and innovation made possible this combination of three superb component sections on a single chassis: Tuner, Preamplifier, and Power Amplifier. Internal connections between these component sections ensure optimum performance from each section, and retain the full flexibility of separate components. The extraordinary flexibility of your Model 2230 permits the connection of: two stereo pairs of loudspeakers; headphones; a turntable or record changer; an additional tuner (such as SW or LW) and a TV sound source. Record, playback, and copying capabilities are included for a tape playback deck or two recorders.
