Flexibility characterizes the SR4021. Not only does it boast 80 watts continuous output from each channel of its stereo amplifier, it includes all the video switching capability to fully integrate a home entertainment system that includes both audio and video sources. From its extruded aluminum front panel to the preamp output/main amp input jacks, the SR4021 is built to support a wide variety of system configurations. There’s a front panel infrared sensor and three pre-programmed code sets that make this component well-suited for remote zone use. Two sets of loudspeaker outputs, a detachable AC cord, and a Marantz System Remote add the final touches for all-in-one utility, and easy placement almost anywhere.
